Mining bitcoin on GPU.....

Mining bitcoin on GPU..... submitted by closest-num-2-0 to Bitcoin [link] [comments]

I earned about 4000% more btc with my android tablet than with a $250 ASIC mini rig setup using GekkoScience Newpac USB miners!

Requirements:
1.) Android Device with access to Google Play Store. *I haven't tried yet but you may be able to use tis on Android TV devces as well by sideloading. If anyone has success before I try, let me know! -Note, I did this with a Samsung Galaxy Tab S6 so its a newer more powerful device. If your android is older, your profts will most likely be less than what I earned but to give a projected range I also tested on my Raspberry Pi 4 running a custom LineageOS rom that doesn't allow the OS to make full use of the Pi's specs and I still got 500 h/s on that with Cloud boost, so about 60% of what my Tab 6 with MUCH Higher Specs does.
**Hey guys. Before I get started i just wanted to be clear about one thing. Yes I have seen those scammy posts sharing "miracle" boosts and fixes. I have a hard time believing stuff online anymore. But this is honestly real. Ill attach photos and explain the whole story and process below. Thanks for taking the time to read and feel free to share any thoughts, concerns, tips, etc*
So last week I finally got started with my first mini rig type mining build. I started getting into crypto about a year ago and it has taken me a long time to even grasp half of the projects out there but its been fun thus far! Anyways my rig was 2 GekkoScience Newpac USB miners, a Moonlander USB miner to pair with an FPGA i already had mining, a 10 port 60W 3.0 USB hub and 2 usb fans. The Newpacs actually are hashing at a combined 280 g/s which is actually better than their reported max hash rate when overclocked. Pleasant surpise and they are simple!! I just wanted to get a moonlander because my fpga already mines on Odocrypt for DGB and I just wanted to experience Scrypt mining and help build the DGB project. The Newpacs are mining BTC though.
After I got everything up and running i checked my payout daily average after 1 week. I averaged .01 a day TOTAL between all three miners with them all perforing ABOVE SPEC!!! I had done research so i knew I wouldnt earn much. More than anything i just wanted to learn. But still. I was kinda surprised in a negative way. Yesterday I actually earned less than .01 Frustrated I went back to scouring the web for new ideas. About a year ago, when II was starting, I saw an app on my iphone called CryptoBrowser that claimed to mine btc on your phone without actually using phone resources using a method of cloud mining. I tried it for a week and quit because I earned like .03 after a ton of use and seemed scammy. Plus my iphone actually would get very hot when doing this so I quit using it as it seemed like a possible scam with all the cryptonight browser mining hacks and malware out there.
Anyways I was on my Galaxy Tab S6 and saw that CryptoBrowser released a "PRO" edition for 3.99 on Google Play. I bought it for Sh*ts and giggles and booted it up. It came with what they called "Cloud Boost" Essentially this is a button you press and it multiplys the estimated hashrate that it gives you device by the number shown on the boost button. (With the purchase of PRO you get one free x10 boost. You can purchase additional boosts to use with other android devices but those are actually pretty pricy. Another x10 boost was like $25 if i remember correctly).
I played with it for about an hour to see if it actually worked like it said it would this time. To my surprise, as i was browsing, my device didnt increase in temperature AT ALL!!!!! I checked my tast manager to confirm and it was indeed true, my memory and usage barely went up. it was giving me an estimated range of 80-105 on the hashrate. Once i pushed the x10 boost button, that went to 800-1150 h/s. I switched my screen to not go to sleep, plugged it to the charge and let it run on the browser page, hashing. When you push the boost button, it runs for 3 hours at the boosted speeds. After that it goes back to normal but if you press the button again, it boosts everything again. There is no limit to how many times you use it. After checking what I earned after 24 hours, I HAD MADE .40 in BTC!!!!! I JUST EARNED OVER 4000% MORE THAN MY $280 MINING RIG EARNED ME!!!! I was blown away. Maybe this was a fluke? I did it again next day. Every 3 hours or so I would push the button again but thats all. Sure enough, .35 that day. Also, it realy BTC. I requested a payout and although it took like 12 hours for them to send me an email stating they had just sent it, I actually did recieve the state amount of BTC within 24 hours in my personal wallet. The fees to send are SUPER LOW!. Like .01
Below I will list the steps I took, along with an explanation of thier "Mining" process on Androids. Reminder, this ONLY WORKS ON ANDROIDS. Also DO NOT use cryptobrowser on a physcal laptop or desktop. I ran it on an old laptop for three days last year and it fried it. It does actually use your hardware on those platforms to mine and it is not efficnet at all as I suspect they prob steal over half of your power for themselves using the REAL RandomX protocol via browser mining which is EXTREMELY INEFFICIENT DONT TRY IT!!
-----How To Do This Yourself:
Cryptotab Browser states the program works on Android devices by estimating what it thinks the hashrate would be for your device specs and siimulates what you would mine in a remote server however you still earn that estimated coin amount. It is not a SHA-256 process or coin that they say is mining, rather it is XMR and they swap that and pay it out to you in BTC Bitcoin. However I know damn well my Tab S6 doesnt hash 80-105 h/s on RandomX because I have done it with a moodified XMRig module i ported to Android. I got 5 h/s a sec if I was getting any hashes at all. But thats besides the point as I still was making money.
Now, when you press that cloud boost button it immediately boosts that hash rate it estimates by the number on the cloud boost. As stated above, you can purchase more boosts and gift them or use them on extra android devices that you may have. Again, they are pricey so I'm not doing that plus it would just mean that I have another device that I have to leave on and open. The boosts come in x2, x4, x6, x8 and x10 variants. Again, they have unlimited uses.
Here is the link to grab yourself CryptoBrowser Pro from CryptoTab. This IS A REFERRAL LINK! This is where I benefit from doing tis tutorial. Like i said, I want to be transparent as this is not a scam but I'm also not doing this out of the love of my heart. Their referral system works in that people that use the donwload the app using your link are your stage 1 referrals. Anytime they are mining, you earn a 15% bonus. So say they mine $.30 one day. You would get paid out an additional $.045 in your own balance (it does not come out of the referred user balance fyi so no worries). Then lets say that referred miner also gets their own referrals. I would get a 10% bonus on whatever THOSE people mine. This goes on and on for like 8 tiers. Each tier the bonus percntage essential halves. So again, I stand to benefit from this but it also is stupid to not make this visible as its WAY CHEAPER, EASIER AND MORE PROFITABLE TO GET BTC USING THIS METHOD THAN IT IS USING ASICS!! THIS EARNS ALMOST AS MUCH BTC AS AN ANTMINER S7 DOES RUNNING 24/7 ONLY WITHOUT THE HUGE ELLECTRICTY BILL AND COSTS!!!!)
Thats it. Again, if you have concerns, let me know or if you have suggestions, other tips, etc... mention those as well!!!

GPU Mining Crash Course - START HERE!

Welcome All to the GPUMining Crash Course!
With the increase in prices in cryptocurrency, a lot of people are getting back into mining and a lot of people are brand new to the concept overall. So, I quickly wrote this crash course to help you understand what to expect and how to successfully mine your first cryptocurrency. This crash course isn't gonna have all of the fluff you'd see in a normal publication. This is just everything you need to know to get up and running on your first cryptocurrency mining rig.

What is cryptocurrency mining?

One of the main things about cryptocurrencies is that they are "decentralized". Sounds great, but WTF does that even mean? Well, the easiest way to explain it is...
You know how if you want to send your friend/family money digitally, you can do so through your bank. Your bank likely takes a transaction fee and in a few days they will transfer the money. Since cryptocurrencies are decentralized, they don't have a bank or organization to fulfill the transfer of money. Instead, they outsource the computing power of their cryptocurrency network to miners (soon to be you). These miners are verifying transactions, securing the blockchain, and powering the cryptocurrency's specific network among other things. As an incentive, the miners collect transaction fees on the transactions that they verify and collect block rewards while new currency is still being introduced into the ecosystem.

What kind of rig should I build?

You can mine cryptocurrencies using your CPU, GPU, FPGA, or ASIC, but this is a GPU Mining subreddit, so I will cater this to GPUs.
For building a great all-around GPU rig, there are two models of GPUs that I'd recommend:
Both of these GPUs have solid hashrates across most mining algorithms and for a decent price! You should be able to find both of these kinds of GPUs used for around $200-$250 each, which is a great price if you know what happened during the last mining craze! ($200 GPUs were out of stock everywhere and people were reselling them for $600+ each)
There are also plenty of great AMD GPUs for mining, but I've worked mostly with Nvidia so that's why both of my recommendations are Nvidia and not AMD.
Other parts to your rig that you'll need are listed below. Most of these can be pieces of crap and are just needed to make the rig actually run, but the one spot you DON'T want to cheap out on is the power supply unit. A decent power supply unit will keep your home from burning down while also keeping your rigs up and running smoothly. Here are my recommendations:

She's built, now what?

Now you need to do a few things. I am a Windows miner, so I will be speaking to Windows here:
  1. Update Windows - Do all of the updates. Just do it.
  2. Update Drivers - Go to the EVGA website and download GeForce experience. It will keep your GPU drivers up to date.
  3. Go to Windows Device Manager and make sure all of your GPUs show up under "Display Adapters". If it is there, but it isn't showing the Name/Model of the GPU as the name, right click it and select "Update Driver". This should fix it.
Assuming you've done all of this, you're ready to download a mining application.

Mining Software

There are tons to choose from! Claymore, Phoenix, EWBF, LolMiner, etc... It can be overwhelming pretty quickly since they all have different algorithm support, speeds, efficiencies, and a whole lot more. On top of that, in order to get them running you need to set up batch files to call the proper exe, point you to the correct pool, and a whole bunch of other stuff that can be confusing to a new user. Not to mention, you will probably need a separate miner, config file, batch file, etc. for each different algorithm that you're interested in mining on.
Instead, I recommend that you download a miner management software that will take care of most of this tedious work for you. There are a few in the sidebar, but the /GPUMining favorite is AIOMiner. It was developed by our very own community member, xixspiderxix with the intention of making mining as easy as possible to do and without any fees. It supports over 100 different algorithms, so you'll be able to mine nearly ANY cryptocurrency you'd like. Just download it from their website and it will take you through a quick tutorial to help you get set up! You can also connect your rig to their website for remote monitoring and control. You've probably seen a few of their posts around this subreddit.
Other Windows mining softwares include:
Note: Many mining softwares have fees built into them. Most are around 1%, but can go as high as 5% or greater! You want a mining software with little or no fees at all so that you get to keep as much cryptocurrency as possible. These fees aren't something you actively pay, the software will automatically take it by mining on the developers behalf for a given amount of time and then switching back to mining on your own behalf. So, please be diligent in the software that you evaluate and make sure it is reputable.

I keep hearing about NiceHash. What is that?

The asshole of the mining industry. Jk, but not really.
NiceHash is a software program that allows you to sell your rig's hashing power to someone on their marketplace. They market themselves as profitable mining, but you're not really mining. You're selling your power in exchange for Bitcoin.
They did a great job telling people that with them, you're always mining the most profitable coin, but that's just not true. Since it is a mining marketplace, they make you mine whatever their most expensive contract is. If their contracts are below market prices, then you're not operating as efficiently and profitably as you could be.
NiceHash also has a sketchy history, which continues to this day. In 2017, they were hacked and lost $65M worth of Bitcoin. No one got paid out for MONTHS and many of their executives conveniently resigned. Their platform is also used to destroy cryptocurrencies. Since people are able to purchase mining power on their platform, people have used their platform to purchase enough mining power to control individual cryptocurrencies and duplicate coins, which increased the malicious user's wealth while completely destroying the integrity of the coin's blockchain. HoriZEN (formerly ZenCash), Ethereum Classic, and many other great cryptocurrencies have been the victim of NiceHash's platform.
For this and many other reasons, we highly recommend that you stay AWAY from Nicehash. We understand that it is extremely easy to use and you get paid in bitcoin, but they are destroying the industry with their greed and lack of motivation to change their platform for the protection of cryptocurrencies.

Concluding Thoughts

This is pretty much everything you need to know to get started. We covered the hardware, setting up the software, which software to use, and AIOMiner's tutorial will get you up to speed on how to actually mine the cryptocurrency that you want better than I can explain it, so I'll leave that part to them.
If you have any questions on this crash course, please leave a comment below where myself and other community members will be able to help you out.

THE END OF ALL ASIC MINERS? - Monero's New Superweapon: "Time Locked Proof of Non-ASIC work challenge reward" algorithms.

I propose the following algorithm to end this War of attrition with ASIC / FPGA manufacturers , hopefully once and for all and save us Precious PoW Tweaks during the upcoming forks.
"A time-locked, Proof of 'Non-ASIC work' Challenge reward algorithm"
Here's an image to help you visualise how the algorithm works (details below):
https://imgur.com/a/9S8dA
Here's why we need it:
ASIC manufacturers mine in Secret to attack our decentralized network. They'll win the war since they'll 'get their investment back' before we brick their ASICs, allowing them to launch never-ending attacks against our decentralization, for eternity.
Quick Overview
This algorithm uses the concept of "time-locked reward challenges".
The algorithm ‘time-locks’ the reward, then issues a ‘non-ASIC’ work challenge during each regular PoW Fork, which distributes mined rewards only to CPU and GPU miners who can pass the challenge and prove they are not ASICS, by maintaining their hashrate during the ASIC downtime.
These Hash-rate challenges after PoW Forks successfully ‘detect’, and ‘Severely Penalize’ anyone Mining with an ASIC/FPGA, even those in Secret.
Proof of Concept: An Actual Demonstration
I'll demonstrate this algorithm in action:
Please see this image to help you Visualise how the algorithm works:
https://imgur.com/a/9S8dA
There is a critical flaw and uniquely identifying feature that exists in absolutely 'ALL ASIC and FPGA miners', even those mining in Secret.
As most of you may know, with the upcoming V7 PoW hardfork,
Instead of just destroying an ASIC with a fork, we can further exploit this to attack the ASIC Manufacturer or Miner by taking back all their mined rewards and giving them to the community
The Special timeframe is PoW Fork + 'N' Days. ('N' being however many days remaining where it would be "impossible" to build and startup a new ASIC/FPGA after the fork.)
To exploit this, the algorithm introduces a period of time called the "Mining Rewards Collection Timeframe" (MRCT), the time period in between regular PoW Hardforks. the grey shaded area in this image
This "Mining Rewards Collection Timeframe" is a time whereby all mining profit rewards are 'time-locked' or held hostage in escrow, on either the mining pool, or on the Actual Blockchain code itself, or Both, depending on where this algorithm is eventually deployed.
The algorithm stores the wallet address a mining reward belongs to, and the maximum hash rate (or maximum value adjusted share rate per day) observed during the "Mining rewards collection timeframe" for that particular wallet address.
This "Mining Rewards Collection Timeframe" can be of any duration as required by the developers; 1,2,3,4,5,6 Months or longer . The longer This Timeframe, the more dangerous it is to ASIC miners. Meaning we don't have to rush with forks.
Since it's time-locked, mined coins/rewards cannot be cashed out until the coming challenge; However, mining pools can still choose to payout smaller miners before that time if they have a 'good stable Non-Asic Hash challenge passing history', or a deposit on file, or at their own risk, so most good miners don't have to wait to cashout rewards!. Big miners on the other hand, won't care! Why? Because the delay doesn't cost them anything. (it's a TINY TINY inconvenience compared to the damage ASICs would do to GPU mining profits. I hope this makes sense)
Now for the Critical ANTI-ASIC Work Challenge.
Time passes and the mining rewards collection timeframe ends with a Hardfork that changes the PoW algorithm slightly,
All ASICS and FPGAs are INSTANTLY destroyed.
At the same time, the mining rewards from that collection timeframe are now ready to be paid out.
Since only the CPU / GPU miners are able to hash normally,
The Algorithm now issues a Hash Rate challenge to determine how much of the coins mined were actually mined by ASIC or FPGA miners.
The challenge is nothing special. Miners just have to leave their miners running normally at maximum speed for the period of the challenge, same as they do everyday!
During this challenge, their "Average Maximum Hash rate during the challenge" is compared to the "Maximum Hash Rate speed" recorded on the blockchain during the Mining Rewards Collection Timeframe.
See the green dotted line in the image
Thus at this point, since ASICs are DEAD, they cannot Hash at the same rate during this challenge period, so any significant difference in hashrate would thus clearly indicate the use of an ASIC or FPGA miner.
Now, we have all the information we need to STRIP ASIC Miners of ALL their gains, and Reward GPU miners instead.
As shown in the earlier image
What if a 1 GPU breaks in a 12 GPU mining farm during the challenge? (Very rare) or for some reason, you can't mine during that period? then the miner can simply rent the GPUs from nicehash for the Challenge. An ASIC miner however, cannot use this strategy (because ASICS are not GPUs, explained further below). Also we can implement a 2nd chance option; the confiscated reward may be frozen for the next Cycle; and the miner may get a 2nd chance to prove the hashrate again, with a % reward penalty.
The Beautiful thing is that If ASIC miners fail the challenge, Everyone gets a Bonus share of the Reward Forefitted by the ASIC miners, So Everyone wants the ASIC miners to fail so they get Free extra money. and thus have a financial reason to support this algorithm.
*There is no escaping it... or is there?
Is it ASIC PROOF? Can you Cheat this algorithm?
I've also tried to see if you can work around this algorithm:
  • Example 1: What if they switched in GPUS to mine for an ASIC during the challenge? Well, that wouldn't work. When the challenge comes, they can either save the rewards mined by the GPUs, or save the rewards mined by the ASICs, One will always be lost and result is the same anyway because you'd only get paid for the Hash rate of the GPU. The ASIC portion of the hash rate will ALWAYS be lost.
  • Example 2: What if they use the GPUs to mine a different coin and have them only hash for the ASIC during the challenge period?
  • Consider the Antminer X3. at 200KH/s, to support just "ONE ASIC", they would need over 200 RX 580 Cards or 100 VEGA cards to pass the challenge... costing well over $60,000 (SIXTY THOUSAND DOLLARS) and if they depreciate at ~ 10~15% a year, they'd lose $6000~$9000 a year. it's not enough to cover your losses,
  • Also, What other coin could you mine? If ASICS are so powerful, there won't be another coin except those running this algorithm. Then, the dev can choose to issue the challenge at the same point as the other coin using the same algorithm, so they lose all rewards from one coin as 1 rig cannot sustain two challenge algorithms at the same time.
  • Example 3: What if they just leave some GPUS on standby to avoid the power costs? Then ASIC's would still be unable to be mass produced anyway. Because for every ASIC Mass produced, you'd need to Mass Produce 200 times the GPUS to support them in their place, and own of all them. practically impossible.
  • Example 4: What if they rented hashing power from Nicehash to fill in during the Challenge period?
  • Yes, but so can we! The beautiful thing about this algorithm, is if we rent the limited hashing power on Nicehash first before them at break even or loss, it doesn't matter, Because, the ASIC miner cannot rent and hash rate and will fail the challenge, and Forefit the ENORMOUS amount of Rewards to the community. Imagine, Mining at such a high rate for months on end , the rewards confiscated and paid to GPU miners will easily offset any of the tiny losses renting hashrate from Nicehash, so ultimately, The ASIC miners lose Everything, and the community (you and me) gets all their money.
  • Also if ASICs Dominate the crypto market, there won't be any GPU to rent, all remaining coins would be mining this algorithm, meaning they would have to save their own hashrate for themselves, not rent it to ASIC miners. otherwise they lose their reward. Brand new users may rent their GPU's but its no where near enough to cover the ASIC hash shortfall in the challenge.
  • Example 5: What if they waited till we exhausted our supply of PoW fork tweaks? That's the beauty of this algorithm!. We don't actually have to tweak the PoW algorithm on a constant basis! We can intentionally leave it the same. So Everyone passes the Challenge, Then when we do detect an asic "trying to Mine their Money Back in secret (as they do now)", We tweak the PoW at the Next Hardfork. Destroying and bankrupting their very first attempt, and we get all their money and rewards, So there's no need to waste a PoW tweak in a pre-emptive strike, because the rewards are Time-Locked to the future. We can lie in wait with a single PoW like a Trap, and eat them alive (literally we get all their rewards after the challenge!). We can maintain this lethal threat to ASIC manufacturers without having to change the PoW at all!
And remember, all this effort is just for ONLY, ONE ASIC. meaning you Can't mass produce it.
So ultimately it wouldn't even make sense to even develop an ASIC, as you'd be far more profitable just mining only with the 200+ GPU's required to cheat the algorithm.
*So in summary, *
  • No ASIC/FPGA miner can escape the challenge. Not even those running in secret.
  • All ASIC miners are guaranteed to suffer a huge (possibly fatal) financial loss, with no prospect of any return on investment. Time locked rewards ensure No secret pre-mining with ASICs is possible. ASICs are destroyed with each challenge, all R&D and manufacturing costs and the electricity bill used to power them is wasted for basically "ZERO returns",
  • …..and lets not forget that all their rewards gets given away to other honest miners like you and Me!. ( LOL!) or potentially the developers of the fork :)
  • As long as the algorithm is active and used by multiple coins, no ASICs will ever exist to mine in secret,
  • We save precious PoW tweak changes, since there's no need for a pre-emptive PoW strike to prevent 'ASIC hit and run' pre-mine scenarios.
  • ASIC manufacturers see that the war is un-winnable and go invest in other things,
So, in theory, The War Ends. (at least for a very good part of the future)
As they say: " Don't build a wall and hide in fear.... Build a wall and launch missiles from behind it against the enemy so they will never dare attack us again."
I would like to point out that time locked reward challenges are already in use by the Olympic games to Strip drug cheats in the past by storing samples and testing them in the future, and it's also in the PPLNS minig pool algorithms to deter pool hopping cheats, and also in the Bitcoin's Lightning network in the form of decrementing time-locks" that 'enforce the transfer of funds' under certain conditions.
Is it beautiful? Will it work? Can it be done? Let's discuss this

Debunking myths about mining and GPUs

E: Going to bed, will contribute more tomorrow. Thanks for the discussion!
Myth: Mining is more stressful than gaming. Fact: It depends. During the old days, this was plausible, because older GPUs (Pre-polaris) are/were bottlenecked by core clock when mining the most profitable coins. Thus, miners overclocked and overvolted these cards quite frequently, especially with cheap electricity. This meant that those cards were often run hot, pushing the limits and stressing VRM and fans quite a lot. Nowadays, ethash (Ethereum) is the most profitable algorithm for AMD cards 99% of the time, and newer GPUs (Polaris) are limited by memory bandwidth and latency. Miners can underclock core to the low 1100MHz range before seeing performance drop. To save power, miners who know what they are doing also undervolt, since it is no longer necessary to sustain a high core clock. Thus, it is quite feasible to run polaris cards below 70C at a reasonable fan speed. However, dual mining (mining more than one coin at once) does increase power consumption by up to 20%, and there are also idiots who run their polaris cards OCd while mining. With the exception of a few idiots, miners treat their Polaris GPUs pretty much the same; that is, running underclocked and undervolted 24/7 with a memory strap mod and mem OC. On the other hand, former gaming cards are highly variable in use cases. Some gamers leave their cards at stock settings, some undervolt, and some OC and/or overvolt. Most of the time, these cards are thermal cycled far more often than mining cards, which is known to weaken solder. Another thing to consider is that manufacturers have learned (somewhat) from their mistakes of putting shit tier fans in GPUs, and many fans on modern GPUs are ball bearing and/or swappable. Even some budget cards, such as MSI Armor, use decent ball bearing fans. Bottom line: the risk of buying mined Polaris cards is not as high as the risk of buying older mined cards. I would not be against buying mined polaris cards, but it's not necessarily better than buying a gamer's card instead. At the end of the day, it depends more on how the owner treated it than what they used it for.
Myth: GPUs are obsolete because of FPGAs and ASICs Fact: Mostly false. Older algorithms such as scrypt and SHA256 (lite/doge/feathebitcoin etc) are no longer feasible to mine with GPUs, but there have been multiple algorithms since then that are built to deter ASICs; most of the time it is done by making it memory-hard because designing an ASIC with high memory throughput is considerably more expensive to design and manufacture. Many devs prefer their blockchain to be ASIC resistant to avoid the concentration of power problem that Bitcoin is having nowadays, where a giant, near-monopolistic ASIC manufacturer (Bitmain) is causing a lot of (subjective) controversy. Blockchains based on ethash (Ethereum and its forks), equihash (Zcash and its forks) and cryptonight (Monero and forks) are some examples, but there are scores of other shitcoins and a few other algos that are GPU dominant. It is almost impossible that there will be another ASIC takeover, which is what was responsible for the stop in GPU demand in the bitcoin and litecoin days. Bottom line: ASICs no longer threaten GPU miners, or the demand for GPUs
Myth: Ethereum switching to Proof of Stake will kill mining soon Fact: Doomsayers have been preaching about proof of stake since late 2015. It has always been "coming soon." The fact is, the Ethereum roadmap goes from proof of work (mining) -> Casper (mining + PoS) -> Metropolis (PoS). Currently, the release date of Casper is not even announced yet, nor is it being tested in a (public) testnet. Proof of Stake might one day take over, but mining is here to stay for a while yet. Another thing to consider is that there are tons of other GPU mineable blockchains, and although Ethereum is biggest, it is certainly feasible that mining stays profitable even after Ethereum goes PoS (if it ever does). However, it is possible that profits will be low enough to discourage new miners. Bottom line: It's very unlikely. E: I screwed up the roadmap; here is a better source than me with some interesting information: https://www.ethnews.com/ethereums-vitalik-buterin-gives-keynote-on-metropolis
Myth: The current Ethereum demand spike is a bubble Opinion: Honestly, I don't know. I would not be surprised if stricter regulations on ICOs come sooner or later, which would fuck with Ether prices. There is also the inherent volatility of cryptocurrencies. However, it is also possible that blockchain technology continues to gain traction; that is, the price could just as easily go up as go down. Although it's fun to read about other people's opinions, only time-travelling wizards can tell you when it will become economical again to upgrade your poor HD5770. Bottom line: No one knows.
Myth: Miners will "steal" all the RX Vegas Fact: Only a reckless miner would buy Vegas on release, since mining performance is not known. In fact, it is possible that it can't mine at all (or at some stupidly low speed) until devs add support to existing miners. It would be even more reckless than gamers who buy without seeing benchmarks, since at least gamers can expect the games to actually run. It's also not necessarily the case that Vega will be good once miners do add support. Maybe there will be enough reckless miners to affect supply, maybe not. Of course, it is possible that miners will deplete the supply after it is demonstrated that Vega is good for mining. Bottom line: Most miners won't preorder, but it's possible that a significant number will. E: Important to remember that even if mining demand isn't high, doesn't mean that supply will be plentiful.
Myth: Nvidia cards SUCK at mining Fact: Mostly false. They USED to suck in the old pre-Maxwell days, but now they are actually more efficient at mining Ethereum and Zcash compared to AMD cards, even after both cards are undervolted. The flipside is that they (used to) cost more for the equivalent hashrate. For reference, my old 5xRX470 rig drew just under 800W when mining ETH only and hashed at 150MH/s. My current 6xGTX1060 rig draws just over half of that (<450W) and hashes at about 135MH/s. Certainly not as good in raw performance, but they are viable nonetheless, especially given the AMD GPU shortage. In fact, Nvidia cards (1060 and especially 1070) are becoming scarce as well. Bottom line: Nvidia is still the underdog when it comes to mining, but far from irrelevant nowadays.
Myth: 4GB cards will be obsolete for mining soon Fact: FALSE. The Ethereum DAG is not even 3GB yet, and won't be for a few months. The recent reports of 4GB Polaris cards slowing down soon due to DAG size is caused by limited TLB capacity, not VRAM restrictions. Polaris cards will still be able to mine ETH forks such as Expanse and UBIQ without diminished speed, and even if they are used to mine ETH, it is not that much of a performance hit at first. It would certainly not make polaris useless or undesirable for mining anytime soon. Tahiti GPUs already suffer from this issue and Hawaii is the most resistant to this issue. Have not benched Nvidia at a later epoch.
Myth: Creating miner-bashing posts on Reddit will help alleviate the GPU supply problem Fact: False, you are simply giving cryptocurrencies and mining more exposure to the general public, increasing demand.
Myth: Mining-specific GPUs will solve the shortage problems Opinion: There's not enough info to tell yet, but I am a skeptic for the following reasons. First, no display limits the resale value of the card for obvious reasons. IMO, the whole point of crypto mining from a profitability standpoint is to have a hedge against coin volatility (hardware is still worth something if the coin crashes). Otherwise it is much less effort to just buy and hold the coin. If the hardware is useless without demand from other (significant) sources, then it doesn't make much sense to buy it unless the price is extremely low. I'm sure that cost-downing the PCB and warranty will make for a cheap card, but it has to be extremely cheap and plentiful in supply, or else miners will buy whatever they can get. I could envision "failed" chips (not meeting spec of consumer editions) being stuck in miner cards, but I doubt there are enough to meet demand without ramping up production as a whole, which carries its own risks. I guess that it would help a little, but probably not solve the problems. Alternatively, since modern GPUs are bottlenecked by RAM when mining, it might be enticing to miners to have the fastest (GDDR5) RAM on the market (probably the 9gbps chips from the 1060 6G 9gbps edition, although I don't have one to test). However, my previous points still apply; buying such a card without display outputs carries a big risk. Bottom line: It's not a great idea, unless they are super cheap or use really good RAM.
Hope this helped; if you have any further questions I will try to answer them. I'm both a gamer and miner who uses both AMD and Nvidia roughly equally and don't favor one group over another. I've mined and gamed on all high end AMD GPUs since Tahiti (except Tonga) and all Pascal cards except 1050ti.

Electroneum Fork 324500

Source: https://www.facebook.com/electroneum/posts/2030562537205714
Hi Everyone!
ALL ELECTRONEUM NODE OWNERS MUST UPDATE THEIR SOFTWARE BY BLOCK 324500 (approx. 36 hours from now – this is an URGENT UPDATE – PLEASE SHARE THIS INFORMATION)
We have an urgent software update below for anyone who runs a full Electroneum Node. If you don’t know what a node is , don’t worry! You won’t need to do anything.
We also have a VERY exciting update about an upcoming listing on a top 10 exchange.
How will I mine Electroneum after this update?
Instant Payment vendor API is open for BETA applicants.How can ETN change the world?
Please note that nothing in this message refers to MOBILE MINING – we are referring to the underlying blockchain miners.
Urgent Electroneum Node / RPC / Command Line Wallet Update
ALL ELECTRONEUM NODE OWNERS MUST UPDATE THEIR SOFTWARE BY BLOCK 324500 (approx. 36 hours from now – this is an URGENT UPDATE – PLEASE SHARE THIS INFORMATION)
https://github.com/electron…/electroneum/releases/…/v2.1.0.0
It’s only been a few short days since I made a video and said “our fork went well! We’re ready for 20m Users!”.
The fork was a great success, from a technical standpoint. Unfortunately, we never got back the number of GPU miners that are needed to ensure our network runs smoothly and has stable block emission. A new phenomenon has emerged where a number of users are mining Electroneum in waves. They come on and then leave after a few hours in a coordinated manner to mine ETN in a completely selfish way. We can’t blame people for maximizing their profit, but we have not built up the amount of “hashing power” that is required to make this impossible and create the stability we need in the network.
This has left us at risk. As such, we have to take urgent action to stabilise our network and protect the Electroneum community.
Coinbene Listing Electroneum & our network stability
We have formally agreed and signed contracts to be listed in July on the AWESOME, top 10, cryptocurrency exchange https://Coinbene.com & https://Coinbene.com.br
Coinbene have 1.5m active users and are a GREAT fit for Electroneum. Their primary markets are Latin America and Asia – which fits perfectly with Electroneum’s customer base. They have seen enormous growth over the last few months and have been very positive about the Electroneum Project.
Whilst this is great news, we will need much more hashing power to ensure we have network stability for our listing on this exchange, so we’ve taken the decision that we can’t wait any longer for GPU miners to return to us and we must run an urgent software update to re-introduce ASIC mining to Electroneum.
This is a very positive move for Electroneum. A great deal of Bitcoin’s trust and appeal is from the enormous hashing power and distribution of miners on the network. Bitcoin & LiteCoin have embraced ASICs and we feel that it is the right thing for Electroneum to do the same.
ASICS are becoming more prevalent, they cost considerably less to run than a GPU rig and use a fraction of the electricity. We are going to encourage more ASIC ownership and take our hashing rate up to (and beyond) the enormous levels of hashing power that we had before the May fork.
There is a further development. The first generation of hardware called an FPGA miner is arriving during 2018 and they make ANTI-ASIC capabilities a thing of the past, as they circumvent the slow delivery time of new ASICs by being re-programmable. If we are ready to embrace these rather than fight them, our network hashing power is increased further and our network stability and security is further enhanced.
Because ASICS run cooler, quieter and use a fraction of GPU rig power, they are suitable for MORE people to run in their homes. If you are interested, a search of “Cryptonight ASIC miner” in Google or Ebay will find the equipment needed to mine Electroneum. You will need to be reasonably technical to achieve this!
Having a stable network is absolutely key to both delivering mass adoption and to ensure we have a great relationship with the great exchanges that we’re already listed with, and to encourage more of the larger exchanges to see Electroneum as a coin that they want on board.
How will I mine Electroneum after this update?
If you are a mobile miner – nothing changes. If you are a GPU or ASIC miner then you’ll need to connect to an Electroneum pool but it is important to note that you will need to change your ALGORITHM. You MUST use the algorithm “Cryptonight” and NOT “Electroneum” or “CryptonightV7”. This will ensure your device works after the update. We will communicate this to all pools, but if you are a member of a mining pool – PLEASE LET THE ADMINS KNOW ABOUT THIS CRITICAL UPDATE. They must update their pool node by block 324500, which is only around 36 hours away.
Instant Payment vendor API is open for BETA applicants
Instant Cryptocurrency Payments via smart phone has always been a critical part of what Electroneum required to achieve mass market adoption. It’s never been done, but 9 short months after our ICO we are excited to announce that we have opened to the doors to vendors who would like to accept payment via Electroneum. The application is to be part of the BETA rollout of instant payment, but will operate on the live blockchain with real ETN!
If you run a business or know someone who does – why not recommend they apply to accept ETN. The Press and Marketing opportunities for the first, in any sector, to accept cryptocurrency are huge! Be part of the instant payment API BETA program by completing this form:
https://docs.google.com/…/1FAIpQLSfKTwWT7W4ltmApZO…/viewform
How can ETN change the world?
Instant payment does far more than allow people to pay for their coffee with crypto instead of their VISA card.
If you’d like to know more about Electroneum’s future I suggest you read a fantastic article that describes its coming role in the world, by fellow director Chris Gorman OBE (Officer of the British Empire – awarded by the Queen of England!): https://www.linkedin.com/…/how-cryptocurrency-enable-financ…
Electroneum has one of the largest of all cryptocurrency communities and it is made up of passionate and amazing people. With your support and world changing things we have coming out over the next few weeks, we can use this update to make our blockchain foundation secure and lead the world in mobile cryptocurrency.
I'm sure you agree that we've been through some challenging times which our team have always dealt with and learned from. The strength and support from our community and many of our goals becoming a reality combined with this blockchain update will give us the perfect foundation to deliver the Electroneum vision that we all share.
Thanks for taking the time to read this long message.
Have a great day everyone,

The Problem with PoW

The Problem with PoW
Miners have always had it rough..
"Frustrated Miners"

The Problem with PoW
(and what is being done to solve it)

Proof of Work (PoW) is one of the most commonly used consensus mechanisms entrusted to secure and validate many of today’s most successful cryptocurrencies, Bitcoin being one. Battle-hardened and having weathered the test of time, Bitcoin has demonstrated the undeniable strength and reliability of the PoW consensus model through sheer market saturation, and of course, its persistency.
In addition to the cost of powerful computing hardware, miners prove that they are benefiting the network by expending energy in the form of electricity, by solving and hashing away complex math problems on their computers, utilizing any suitable tools that they have at their disposal. The mathematics involved in securing proof of work revolve around unique algorithms, each with their own benefits and vulnerabilities, and can require different software/hardware to mine depending on the coin.
Because each block has a unique and entirely random hash, or “puzzle” to solve, the “work” has to be performed for each block individually and the difficulty of the problem can be increased as the speed at which blocks are solved increases.

Hashrates and Hardware Types

While proof of work is an effective means of securing a blockchain, it inherently promotes competition amongst miners seeking higher and higher hashrates due to the rewards earned by the node who wins the right to add the next block. In turn, these higher hash rates benefit the blockchain, providing better security when it’s a result of a well distributed/decentralized network of miners.
When Bitcoin first launched its genesis block, it was mined exclusively by CPUs. Over the years, various programmers and developers have devised newer, faster, and more energy efficient ways to generate higher hashrates; some by perfecting the software end of things, and others, when the incentives are great enough, create expensive specialized hardware such as ASICs (application-specific integrated circuit). With the express purpose of extracting every last bit of hashing power, efficiency being paramount, ASICs are stripped down, bare minimum, hardware representations of a specific coin’s algorithm.
This gives ASICS a massive advantage in terms of raw hashing power and also in terms of energy consumption against CPUs/GPUs, but with significant drawbacks of being very expensive to design/manufacture, translating to a high economic barrier for the casual miner. Due to the fact that they are virtual hardware representations of a single targeted algorithm, this means that if a project decides to fork and change algorithms suddenly, your powerful brand-new ASIC becomes a very expensive paperweight. The high costs in developing and manufacturing ASICs and the associated risks involved, make them unfit for mass adoption at this time.
Somewhere on the high end, in the vast hashrate expanse created between GPU and ASIC, sits the FPGA (field programmable gate array). FPGAs are basically ASICs that make some compromises with efficiency in order to have more flexibility, namely they are reprogrammable and often used in the “field” to test an algorithm before implementing it in an ASIC. As a precursor to the ASIC, FPGAs are somewhat similar to GPUs in their flexibility, but require advanced programming skills and, like ASICs, are expensive and still fairly uncommon.

2 Guys 1 ASIC

One of the issues with proof of work incentivizing the pursuit of higher hashrates is in how the network calculates block reward coinbase payouts and rewards miners based on the work that they have submitted. If a coin generated, say a block a minute, and this is a constant, then what happens if more miners jump on a network and do more work? The network cannot pay out more than 1 block reward per 1 minute, and so a difficulty mechanism is used to maintain balance. The difficulty will scale up and down in response to the overall nethash, so if many miners join the network, or extremely high hashing devices such as ASICs or FPGAs jump on, the network will respond accordingly, using the difficulty mechanism to make the problems harder, effectively giving an edge to hardware that can solve them faster, balancing the network. This not only maintains the block a minute reward but it has the added side-effect of energy requirements that scale up with network adoption.
Imagine, for example, if one miner gets on a network all alone with a CPU doing 50 MH/s and is getting all 100 coins that can possibly be paid out in a day. Then, if another miner jumps on the network with the same CPU, each miner would receive 50 coins in a day instead of 100 since they are splitting the required work evenly, despite the fact that the net electrical output has doubled along with the work. Electricity costs miner’s money and is a factor in driving up coin price along with adoption, and since more people are now mining, the coin is less centralized. Now let’s say a large corporation has found it profitable to manufacture an ASIC for this coin, knowing they will make their money back mining it or selling the units to professionals. They join the network doing 900 MH/s and will be pulling in 90 coins a day, while the two guys with their CPUs each get 5 now. Those two guys aren’t very happy, but the corporation is. Not only does this negatively affect the miners, it compromises the security of the entire network by centralizing the coin supply and hashrate, opening the doors to double spends and 51% attacks from potential malicious actors. Uncertainty of motives and questionable validity in a distributed ledger do not mix.
When technology advances in a field, it is usually applauded and welcomed with open arms, but in the world of crypto things can work quite differently. One of the glaring flaws in the current model and the advent of specialized hardware is that it’s never ending. Suppose the two men from the rather extreme example above took out a loan to get themselves that ASIC they heard about that can get them 90 coins a day? When they join the other ASIC on the network, the difficulty adjusts to keep daily payouts consistent at 100, and they will each receive only 33 coins instead of 90 since the reward is now being split three ways. Now what happens if a better ASIC is released by that corporation? Hopefully, those two guys were able to pay off their loans and sell their old ASICs before they became obsolete.
This system, as it stands now, only perpetuates a never ending hashrate arms race in which the weapons of choice are usually a combination of efficiency, economics, profitability and in some cases control.

Implications of Centralization

This brings us to another big concern with expensive specialized hardware: the risk of centralization. Because they are so expensive and inaccessible to the casual miner, ASICs and FPGAs predominantly remain limited to a select few. Centralization occurs when one small group or a single entity controls the vast majority hash power and, as a result, coin supply and is able to exert its influence to manipulate the market or in some cases, the network itself (usually the case of dishonest nodes or bad actors).
This is entirely antithetical of what cryptocurrency was born of, and since its inception many concerted efforts have been made to avoid centralization at all costs. An entity in control of a centralized coin would have the power to manipulate the price, and having a centralized hashrate would enable them to affect network usability, reliability, and even perform double spends leading to the demise of a coin, among other things.
The world of crypto is a strange new place, with rapidly growing advancements across many fields, economies, and boarders, leaving plenty of room for improvement; while it may feel like a never-ending game of catch up, there are many talented developers and programmers working around the clock to bring us all more sustainable solutions.

The Rise of FPGAs

With the recent implementation of the commonly used coding language C++, and due to their overall flexibility, FPGAs are becoming somewhat more common, especially in larger farms and in industrial setting; but they still remain primarily out of the hands of most mining enthusiasts and almost unheard of to the average hobby miner. Things appear to be changing though, one example of which I’ll discuss below, and it is thought by some, that soon we will see a day when mining with a CPU or GPU just won’t cut it any longer, and the market will be dominated by FPGAs and specialized ASICs, bringing with them efficiency gains for proof of work, while also carelessly leading us all towards the next round of spending.
A perfect real-world example of the effect specialized hardware has had on the crypto-community was recently discovered involving a fairly new project called VerusCoin and a fairly new, relatively more economically accessible FPGA. The FPGA is designed to target specific alt-coins whose algo’s do not require RAM overhead. It was discovered the company had released a new algorithm, kept secret from the public, which could effectively mine Verus at 20x the speed of GPUs, which were the next fastest hardware types mining on the Verus network.
Unfortunately this was done with a deliberately secret approach, calling the Verus algorithm “Algo1” and encouraging owners of the FPGA to never speak of the algorithm in public channels, admonishing a user when they did let the cat out of the bag. The problem with this business model is that it is parasitic in nature. In an ecosystem where advancements can benefit the entire crypto community, this sort of secret mining approach also does not support the philosophies set forth by the Bitcoin or subsequent open source and decentralization movements.
Although this was not done in the spirit of open source, it does hint to an important step in hardware innovation where we could see more efficient specialized systems within reach of the casual miner. The FPGA requires unique sets of data called a bitstream in order to be able to recognize each individual coin’s algorithm and mine them. Because it’s reprogrammable, with the support of a strong development team creating such bitstreams, the miner doesn’t end up with a brick if an algorithm changes.

All is not lost thanks to.. um.. Technology?

Shortly after discovering FPGAs on the network, the Verus developers quickly designed, tested, and implemented a new, much more complex and improved algorithm via a fork that enabled Verus to transition smoothly from VerusHash 1.0 to VerusHash 2.0 at block 310,000. Since the fork, VerusHash 2.0 has demonstrated doing exactly what it was designed for- equalizing hardware performance relative to the device being used while enabling CPUs (the most widely available “ASICs”) to mine side by side with GPUs, at a profit and it appears this will also apply to other specialized hardware. This is something no other project has been able to do until now. Rather than pursue the folly of so many other projects before it- attempting to be “ASIC proof”, Verus effectively achieved and presents to the world an entirely new model of “hardware homogeny”. As the late, great, Bruce Lee once said- “Don’t get set into one form, adapt it and build your own, and let it grow, be like water.”
In the design of VerusHash 2.0, Verus has shown it doesn’t resist progress like so many other new algorithms try to do, it embraces change and adapts to it in the way that water becomes whatever vessel it inhabits. This new approach- an industry first- could very well become an industry standard and in doing so, would usher in a new age for proof of work based coins. VerusHash 2.0 has the potential to correct the single largest design flaw in the proof of work consensus mechanism- the ever expanding monetary and energy requirements that have plagued PoW based projects since the inception of the consensus mechanism. Verus also solves another major issue of coin and net hash centralization by enabling legitimate CPU mining, offering greater coin and hashrate distribution.
Digging a bit deeper it turns out the Verus development team are no rookies. The lead developer Michael F Toutonghi has spent decades in the field programming and is a former Vice President and Technical Fellow at Microsoft, recognized founder and architect of Microsoft's .Net platform, ex-Technical Fellow of Microsoft's advertising platform, ex-CTO, Parallels Corporation, and an experienced distributed computing and machine learning architect. The project he helped create employs and makes use of a diverse myriad of technologies and security features to form one of the most advanced and secure cryptocurrency to date. A brief description of what makes VerusCoin special quoted from a community member-
"Verus has a unique and new consensus algorithm called Proof of Power which is a 50% PoW/50% PoS algorithm that solves theoretical weaknesses in other PoS systems (Nothing at Stake problem for example) and is provably immune to 51% hash attacks. With this, Verus uses the new hash algorithm, VerusHash 2.0. VerusHash 2.0 is designed to better equalize mining across all hardware platforms, while favoring the latest CPUs over older types, which is also one defense against the centralizing potential of botnets. Unlike past efforts to equalize hardware hash-rates across different hardware types, VerusHash 2.0 explicitly enables CPUs to gain even more power relative to GPUs and FPGAs, enabling the most decentralizing hardware, CPUs (due to their virtually complete market penetration), to stay relevant as miners for the indefinite future. As for anonymity, Verus is not a "forced private", allowing for both transparent and shielded (private) transactions...and private messages as well"

If other projects can learn from this and adopt a similar approach or continue to innovate with new ideas, it could mean an end to all the doom and gloom predictions that CPU and GPU mining are dead, offering a much needed reprieve and an alternative to miners who have been faced with the difficult decision of either pulling the plug and shutting down shop or breaking down their rigs to sell off parts and buy new, more expensive hardware…and in so doing present an overall unprecedented level of decentralization not yet seen in cryptocurrency.
Technological advancements led us to the world of secure digital currencies and the progress being made with hardware efficiencies is indisputably beneficial to us all. ASICs and FPGAs aren’t inherently bad, and there are ways in which they could be made more affordable and available for mass distribution. More than anything, it is important that we work together as communities to find solutions that can benefit us all for the long term.

In an ever changing world where it may be easy to lose sight of the real accomplishments that brought us to this point one thing is certain, cryptocurrency is here to stay and the projects that are doing something to solve the current problems in the proof of work consensus mechanism will be the ones that lead us toward our collective vision of a better world- not just for the world of crypto but for each and every one of us.

Profitable Crypto Mining: ASIC vs GPU, Which One Is Better?

Profitable Crypto Mining: ASIC vs GPU, Which One Is Better?
If you’re new to mining you probably have multiple questions running through your head right now. Good news is that it gets easier with time, assuming that you do your homework and research, and we will try to help you out.
One of the common questions is whether one should choose GPU or ASIC mining and we definitely have some advice on that topic.
When we’re considering classic POW mining we can quickly rule out CPU hardware for not being efficient and FPGA hardware because of its high costs. This leaves you with ASIC and GPU to choose from.

https://preview.redd.it/igev3y4v8pv31.png?width=1920&format=png&auto=webp&s=2a0c9271fc36252181d086e74101d13875619c80

Buying Mining Equipment

Let’s get things straight — you won’t be able to buy ASIC devices in any of you local electronic shops, even in the biggest ones. There are two ways you can get this hardware: buying it online which shouldn’t be a problem these days unless that’s the newest model you’re after. Second option is to find a local company that sells ASIC equipment.
Also, you can try to purchase the equipment directly from the manufacture company, however, mind the huge customs and delivery fees if the company is located abroad.
It is highly recommended to test ASICs before buying them to make sure the equipment works properly.
GPU or graphics cards and other equipment that you will need to build your very own mining farm can be easily purchased at a regular computer store. The only problem you may have is getting the right set of hardware, so make sure to come prepared.
When buying a used (second-hand) graphics card don’t forget to test it.
What’s better?
If you’re not into hardware and have no clue how to set up a farm by yourself buying ASIC equipment would be a better option as you won’t need to build anything yourself.

Warranty Policy

In general, an official warranty policy for ASIC hardware is up to 180 days since the equipment was shipped to the buyer. When the seller is confident about the quality of their equipment, they can offer their personal 1 month warranty.
When you’re buying computer hardware in most of the cases you are getting full 2 year warranty policy including exchange or repairments of the equipment.
What’s better?
Warranty policy is especially important when you have no chance to check the equipment yourself or when you’re buying large inventory of it. Also, if you plan to go with overclocking, you will probably need a decent warranty as well.
We need to add that when you’re using the equipment accordingly and conduct regular maintenance both ASIC and GPU can work past the warranty period.

Setting Up Process

With ASICs it’s simple: you plug and connect it, pick a pool to join and start mining right away.
With GPU, it’s a little complicated. First, you need to build your farm. You will need a framework, motherboard with installed CPU and cooling, storage unit, power supply, risers and video cards. If you have no experience with assembling computer hardware you’re gonna need to save some time and prepare to put extra effort. Once your rig is ready you will have to install OS and optimize it which is usually even harder than setting up a rig. But luckily we’ve got a solution for that. CoinFly can do the work for you and help you with setting up and optimizing your equipment.
What’s better?
Although ASICs are very easy, you shouldn’t quickly give up on GPU mining. If assembling computer hardware is not a big problem for you, CoinFly will help you with setting it up.

Maintenance

ASIC equipment won’t give you too much trouble: it’s safe, stable, and doesn’t require any special knowledge. Maintenance includes cleaning off dust and oiling the fans.
When dealing with rigs, you will have to work a little harder and study the basics about at least graphics cards’ temperatures and operational frequency. A stable workflow depends heavily on the software and as it has a tendency to fail, it could become a problem. Unless you’re using CoinFly — our system will notify you in case of emergency so you can tune your equipment online.
What’s better?
Once again, when it comes to maintaining ASICs are almost trouble-free. GPU rigs are a bit tricky but when using the right tools like CoinFly to monitor their work, it can serve you just fine.

The Noise

ASICs are loud: when you’re in a room with a working ASIC you’re gonna need to shout, so people can hear you.
GPU farms have no such problem. Some of them are almost silent and that doesn’t affect the cooling process at all.
What’s better?
Maybe the level of noise your equipment makes was not the first issue on your list but we recommend you to consider it. ASICs are suitable only for the commercial and industrial premises.

Mining

ASICs can work with only one algorithm and mine one or several types of cryptocurrencies and are perfect for mining Bitcoin and its forks.
GPU rigs are universal: you can mine a huge variety of coins if you set your miner right.
What’s better?
If you want to mine Bitcoin, you gotta go with ASIC. But think again if that’s what you’re really after. After all, you can choose mining any altcoin that you’d like with your GPU rig and then simply exchange it to BTC. And if you’re lucky enough to mine a coin that will do good ASICs do not give you that choice, however, their mining capability is higher.

Relevance of the Equipment

ASICs are quickly getting out of date as the new models come along. Back in the day, the new versions used to come out every half a year and they were 10 times more efficient. In general, you need to change your ASIC hardware every year.
GPU equipment can perfectly serve you for 2 to 3 years and if you wish to sell the graphics card afterwards that wouldn’t be a problem either.
What’s better?
In terms of relevance, it’s probably reasonable to go with the GPU.

Return on Investment

In the long run, the profitableness of ASICs is higher but because the new models are being released quite frequently you cannot expect huge profits. It is always important to do your research and get the most relevant equipment.
GPU hardware will take its time to pay you back but it also depends if you manage to find the right coin to mine that will eventually increase your profits.
What’s better?
ASIC mining is definitely a good option for those who don’t want to constantly monitor the crypto market.
But in the case that you’re interested in what’s happening in the crypto space and you also have time to do your own research, the GPU farm would the better choice. If you’re not willing to spend your efforts on that, CoinFly Autopilot mode will help you mine the most profitable coin on the market automatically.

Conclusion

ASICs are great for people who can provide a non-residential space for mining and not willing to spend too much time and effort for setting up the equipment and stay updated with the latest trends in the crypto industry.
GPU rigs are suitable for mining at home and won’t scare away all the crypto and computer enthusiasts. If you’re just starting your mining journey but not sure how to do it, we recommend to register on CoinFly. From setting up your hardware to tuning it online and picking the best coin to mine at the moment — we’ve got you covered!

Cryptocurrency Mining History : Journey to PoC

Cryptocurrency just like any other technological development has given birth to many side industries and trends like ICO, white paper writing, and mining etc… just the cryptocurrency itself rises, falls and changes to adapt real life conditions, so does its side industries and trends. Today we are going to be focusing on mining. How it has risen, fell and adapted through the journey of cryptocurrency till date.
Without going into details crypto mining is the process by which new blocks are validated and added to the blockchain. It first took to main stream in January 2009 when the mysterious Satoshi Nakamoto launched the bitcoin white paper within which he/she/they proposed the first mining consensus mechanism called proof of work (Pow).
The PoW consensus mechanism required that one should spend a certain amount of computational power to solve a cryptographic problem (nounce) in other to have the have the right to pack/verify the next block on the blockchain. In this mechanism, the more computational power one possesses the more rights they have over the packing of the next block. The quest for faster hardware has seen significant changes in the types of hard ware dominating the PoW mining community.
Back in 2009 when bitcoin first started a normal pc and its processing power worked just fine. In fact a pc with an i7 Intel processor could mine up to 50btc per day but back then it almost nothing since btc was only some few cents. When the difficulty of the network became significantly high, simple computer processing units could not match the competitiveness and so miners settled for something more powerful, the high end graphic processors (GPU). This is when the era of rigs began It was in 2010. People would combine GPUs together in mining rigs on a mother board usually in order of 6 per rig some miners operated farms containing many of these rigs. Of course with greater power came greater network difficulty and so the search for faster hard ware let to implementation of Field Programmable Gate Arrays (FPGA) in June 2012. A further search for faster, less consuming and cheaper hard ware let us to where we are today. In the year 2013, Application Specific Integrated Circuits (ASIC) miners were introduced. One ASIC miner processes 1500H/s which is 100 times processing power of CPU and GPU. But all this speed and efficiency achievements brought about another problem one which touches the core of cryptocurrency itself. The idea of decentralization was gradually fading away as wealthy and big companies are the once who could afford and build the miners therefore centralizing mining around the rich, there was a called for ASIC resistant consensus mechanism.
A movement for ASIC resistant PoW algorithms began the idea is to make ASIC mining impossible or at least make it such that using ASIC doesn’t give a miner any additional advantage as to using CPU . In 2013 the MONERO the famous privacy coin proposed CryptoNight an ASIC resistant PoW consensus at least that is how they intended it to be. But things have proven much more difficult in practice than they had anticipated as ASIC producers keep matching up to every barrier put in place the PoW designers at a rate faster than it takes to build these barriers. MONERO for example has to fork every now and then in other to keep the CryptoNight ASIC resistant a trick which is still not working as reported by their CEO “We [also] saw that this was very unsustainable. … It takes a lot to keep [hard forking] again and again for one. For two, it may decentralize mining but it centralizes in another area. It centralizes on the developers because now there’s a lot of trust in developers to keep hard forking.” Another PoW ASIC resistance algorithm is the RamdonX and there are many others but could quickly imagine that the barriers to ASIC mining in these ASIC resistance algorithm would eventually be broken by the ASIC miners and so a total shift from PoW mining to other consensus mechanisms which are ASIC resistance from core were proposed some of which are in use today.
Entered the Proof of Stake (PoS) consensus mechanism. PoS was first introduced in 2013 by the PeerCoin team. Here, a validator’s right to mine is proportionate to his/heit economic value in the network simple put the more amounts of coins you have the more mining rights you get. Apart from PeerCoin, NEO and LISK also use POS and soon to follow is EThereum. There are different variations to PoS including but not limited to delegated proof of stake DPoS, masternode proof of stake MPoS each of which seek to improve on something in the POS. This is a very good ASIC resistance consensus mechanism but it still doesn’t solves the centralization problem as the rich always have the power to more coins and have more mining rights plus it is also expensive to start. And then we have gotten many other proposals to combat this among which are Proof of Weight (PoW) and Proof of Capacity (PoC). We take more interest in PoC it is the latest and gives the best solution to all our mining challenges consensus as of now.
Proof of Capacity was first was described 2013 in the Proofs of Space paper by Dziembowski, Faust, Kolmogorov and Pietrzak and it is now being used in Burst. The main factor that separates all the mining mechanisms is the resource used. These resources which miners spend in other to have mining rights is a measure of ensuring that one has expense a none-trivial amount of effort in making a statement. The resource being spent in PoC is disk space. This is less expensive since many people already have some unused space lying around and space is a cheap resource in the field of tech. it has no discrimination over topography… it really solves lots of centralized problems present in all most other consensus. If the future is now then one could say the future of crypto mining is PoC.

Some rational thinking (and numbers) on ASICs/Dedicated Hardware

The current ETH price is bad - we can all clearly see that, having dropped to almost 25% of ATH. So over that period of time miners have lost 75% of their profits + the difficulty increases.
The current difficulty HAS started slowing/plateauing. Just zoom in on that etherscan.io graph for Oct-Present and that is obvious.
Current difficulty is 265 TH/s or so. That’s about 10 MILLION GPUs @ 26 MH average.
The looming fear has been this idea that Dedicated hardware (regardless of ASIC/FPGA/Custom GPUs) are going to completely destroy mining in the near term. I’m here to loudly say that’s a bunch of FUD. Here is my reasoning.
  1. The rumors peg F3 hashrates between 250 and 600 MH for $3000-$6000. $3000-7500 would get you about the same range with commodity GPUs (if you bargain shop and are efficient building rigs). Initial cost is maybe a 10-20% advantage. Those buying used cards get that deal now.
  2. Power usage rumored are 750w or so. Commodity rig with the same GPU power 1200-2400W. So maybe 3x power advantage / operating cost. At $0.10/kW that amounts to $120/mo of savings in the best case, and the 600 MH is currently worth $520 or so at these depressed prices. So you make 23% more.
  3. Next gen GPUs using GDDR6 will almost certainly double hashrates. Without going into the details, it is sufficient to say GDDR6 will double memory bandwidth for all classes of GPUs using it and thus will almost certainly double hashrate for the same power. A major memory change like this hasn’t happened in more than 5 years. Mining has basically never seen it. This should narrow or eliminate any dedicated hardware gap, even if it doesn’t help current card investments... but those are still pretty safe, see #4.
  4. ASIC/Dedicated production is super unlikely to make any significant dent in difficulty for a while. Let’s say the batch size is an extremely aggressive 5,000 units a week, each producing the output of 20 typical GPUs. That’s the same as 100,000 GPUs being introduced a week - but that would only be a 1.1% difficulty increase per week. It would take two years of ASICs for difficulty to double and your $520/mo to drop to $260 - assuming ETH price remained constant. Meanwhile over 4 million GPUs came online between December and January - Thats 10x more new GPU miners per week than Bitmain production could have supported brining online.
You aren’t competing against ASICs. You’re competing against price, which is partially dropping due to all this FUD and uncertainty about ASICs, and you are competing with the millions of get rich quick miners that started, with their GPUs, this spring.
For reference bitcoin ASICs, and other not-ASIC resistant algorithms compete with ASIC systems that are 1-100 orders of magnitude faster for cost/power than the GPU miners. That is NOT the case here, we’re looking at 20-30% savings and only till the next gen of GPUs, and this is why ETH has met its project goal of being ASIC resistant - which does not mean it is impossible to build dedicated hardware to mine ETH, it simply means that such hardware won’t change the landscape.
Bitcoin was also much smaller than ETH in terms of number of GPUs mining when ASICs were introduced, which is why a relatively low volume of ASIC production that were orders of magnitude better than GPUs resulted in such a disruption to Bitcoin mining. The same holds true of the much smaller coins that were being dual mined.
In summary - you are losing profits because of FUD and market shifts lowering price, and that will continue to be why you’re losing money - not ASICs or dedicated hardware. The sooner the community stops running around like chickens with their heads cut off and realigns with focusing on the goals for Ethereum itself, the sooner the situation and price will stabilize. Besides, POS is always coming eventually...

Flashback Friday: When I though I was going to be rich :-)

I was going through my crypto archive and here a picture when time were not just better but unbelievably profitable for a hobby miner (and made me spend a bit too much money on hardware).

This was on 24 January 2018, and I was pulling 0,0026 BTC per day (back then it was 23ish EUR with the EUBTC rate) on 10 low-middle grade GPUs. This was without any kind of OC (I was going full blast, it was just so profitable, lol).
2 * rx570 + 8 Nvidia (3 * 1050ti + 5 1060 6Go).
Now I have 2 more GPUs, finely tuned OC, and I would get around 0,5mBTC/Day (below electricity cost in my region).
https://i.redd.it/ikgdsawsysk11.jpg
I guess when something is too good to be true, it's too good to be true. But I was drawn into it. I was always curious about Bitcoin when BTC was 200 euro but back then it wasn't profitable anyway already because of FPGA and ASIC and I wasn't really clear where to buy BTC that wouldn't scam me of my money. BTC went to 600 euro and I though things have peaked already so I was fuck it I'm too late for the party. I admit FOMO brought me in with the Bullrun end 2017.

Now, we are in september, back in DecembeJanuary I projected that I should BE my initial investment in July and start printing money by then. Right now, I'm something like <30% BE it and the value of my stack is still going down since I've HODL all of my BTC and never sold.

Nowadays, my rig is off because electricity is too expensive to make it run (Western Europe problem I know) so I can't even continue to progress to my BE even when electricity is cheaper at night. Tried mining ETH directly but the difficulty is ridiculous, the value took a nose dive, payout are unpredictably because of pool luck and pplns scheme, tried mining RVN but came late to the party pool luck and payement are even worse on RVN than on ETH.
- I would make more RVN mining ETH and buying RVN with ETH.
- I would also make more ETH mining on Nicehash and purchasing ETH with BTC.
But then, I would be trading so what's the point of mining.

I think I'll go deeper the rabbit hole and start mining speculative low diff coins if I can find a good project, but every project I hear from seems to already being past that point so I can't build a bag :-(

I'm happy I haven't got overboard with the spending and I'm glad I've learn many thing in this space along the way. So glad I didn't pull the trigger on a couple of Titan XP, I seriously considered it back when it was still profitable. But being in profit seems to be a concept that I'll probably never reach. So I'll guess "I'm in it for the tech" like so many people can say.

I guess this post will have the merit to warn potential adventurers to reconsider spending any amount of money they are not ready to be parted from.

If however you have "free electricity" I still wish you good luck because at a large scale you still won't BE the initial investment if you want to build today, and at a small scale, you won't make a buck anyway and just provide cheap hashrate to NH buyers.

The Problem with PoW


Miners have always had it rough..
"Frustrated Miners"


The Problem with PoW
(and what is being done to solve it)

Proof of Work (PoW) is one of the most commonly used consensus mechanisms entrusted to secure and validate many of today’s most successful cryptocurrencies, Bitcoin being one. Battle-hardened and having weathered the test of time, Bitcoin has demonstrated the undeniable strength and reliability of the PoW consensus model through sheer market saturation, and of course, its persistency.
In addition to the cost of powerful computing hardware, miners prove that they are benefiting the network by expending energy in the form of electricity, by solving and hashing away complex math problems on their computers, utilizing any suitable tools that they have at their disposal. The mathematics involved in securing proof of work revolve around unique algorithms, each with their own benefits and vulnerabilities, and can require different software/hardware to mine depending on the coin.
Because each block has a unique and entirely random hash, or “puzzle” to solve, the “work” has to be performed for each block individually and the difficulty of the problem can be increased as the speed at which blocks are solved increases.
Hashrates and Hardware Types
While proof of work is an effective means of securing a blockchain, it inherently promotes competition amongst miners seeking higher and higher hashrates due to the rewards earned by the node who wins the right to add the next block. In turn, these higher hash rates benefit the blockchain, providing better security when it’s a result of a well distributed/decentralized network of miners.
When Bitcoin first launched its genesis block, it was mined exclusively by CPUs. Over the years, various programmers and developers have devised newer, faster, and more energy efficient ways to generate higher hashrates; some by perfecting the software end of things, and others, when the incentives are great enough, create expensive specialized hardware such as ASICs (application-specific integrated circuit). With the express purpose of extracting every last bit of hashing power, efficiency being paramount, ASICs are stripped down, bare minimum, hardware representations of a specific coin’s algorithm.
This gives ASICS a massive advantage in terms of raw hashing power and also in terms of energy consumption against CPUs/GPUs, but with significant drawbacks of being very expensive to design/manufacture, translating to a high economic barrier for the casual miner. Due to the fact that they are virtual hardware representations of a single targeted algorithm, this means that if a project decides to fork and change algorithms suddenly, your powerful brand-new ASIC becomes a very expensive paperweight. The high costs in developing and manufacturing ASICs and the associated risks involved, make them unfit for mass adoption at this time.
Somewhere on the high end, in the vast hashrate expanse created between GPU and ASIC, sits the FPGA (field programmable gate array). FPGAs are basically ASICs that make some compromises with efficiency in order to have more flexibility, namely they are reprogrammable and often used in the “field” to test an algorithm before implementing it in an ASIC. As a precursor to the ASIC, FPGAs are somewhat similar to GPUs in their flexibility, but require advanced programming skills and, like ASICs, are expensive and still fairly uncommon.
2 Guys 1 ASIC
One of the issues with proof of work incentivizing the pursuit of higher hashrates is in how the network calculates block reward coinbase payouts and rewards miners based on the work that they have submitted. If a coin generated, say a block a minute, and this is a constant, then what happens if more miners jump on a network and do more work? The network cannot pay out more than 1 block reward per 1 minute, and so a difficulty mechanism is used to maintain balance. The difficulty will scale up and down in response to the overall nethash, so if many miners join the network, or extremely high hashing devices such as ASICs or FPGAs jump on, the network will respond accordingly, using the difficulty mechanism to make the problems harder, effectively giving an edge to hardware that can solve them faster, balancing the network. This not only maintains the block a minute reward but it has the added side-effect of energy requirements that scale up with network adoption.
Imagine, for example, if one miner gets on a network all alone with a CPU doing 50 MH/s and is getting all 100 coins that can possibly be paid out in a day. Then, if another miner jumps on the network with the same CPU, each miner would receive 50 coins in a day instead of 100 since they are splitting the required work evenly, despite the fact that the net electrical output has doubled along with the work. Electricity costs miner’s money and is a factor in driving up coin price along with adoption, and since more people are now mining, the coin is less centralized. Now let’s say a large corporation has found it profitable to manufacture an ASIC for this coin, knowing they will make their money back mining it or selling the units to professionals. They join the network doing 900 MH/s and will be pulling in 90 coins a day, while the two guys with their CPUs each get 5 now. Those two guys aren’t very happy, but the corporation is. Not only does this negatively affect the miners, it compromises the security of the entire network by centralizing the coin supply and hashrate, opening the doors to double spends and 51% attacks from potential malicious actors. Uncertainty of motives and questionable validity in a distributed ledger do not mix.
When technology advances in a field, it is usually applauded and welcomed with open arms, but in the world of crypto things can work quite differently. One of the glaring flaws in the current model and the advent of specialized hardware is that it’s never ending. Suppose the two men from the rather extreme example above took out a loan to get themselves that ASIC they heard about that can get them 90 coins a day? When they join the other ASIC on the network, the difficulty adjusts to keep daily payouts consistent at 100, and they will each receive only 33 coins instead of 90 since the reward is now being split three ways. Now what happens if a better ASIC is released by that corporation? Hopefully, those two guys were able to pay off their loans and sell their old ASICs before they became obsolete.
This system, as it stands now, only perpetuates a never ending hashrate arms race in which the weapons of choice are usually a combination of efficiency, economics, profitability and in some cases control.
Implications of Centralization
This brings us to another big concern with expensive specialized hardware: the risk of centralization. Because they are so expensive and inaccessible to the casual miner, ASICs and FPGAs predominantly remain limited to a select few. Centralization occurs when one small group or a single entity controls the vast majority hash power and, as a result, coin supply and is able to exert its influence to manipulate the market or in some cases, the network itself (usually the case of dishonest nodes or bad actors).
This is entirely antithetical of what cryptocurrency was born of, and since its inception many concerted efforts have been made to avoid centralization at all costs. An entity in control of a centralized coin would have the power to manipulate the price, and having a centralized hashrate would enable them to affect network usability, reliability, and even perform double spends leading to the demise of a coin, among other things.
The world of crypto is a strange new place, with rapidly growing advancements across many fields, economies, and boarders, leaving plenty of room for improvement; while it may feel like a never-ending game of catch up, there are many talented developers and programmers working around the clock to bring us all more sustainable solutions.
The Rise of FPGAs
With the recent implementation of the commonly used coding language C++, and due to their overall flexibility, FPGAs are becoming somewhat more common, especially in larger farms and in industrial setting; but they still remain primarily out of the hands of most mining enthusiasts and almost unheard of to the average hobby miner. Things appear to be changing though, one example of which I’ll discuss below, and it is thought by some, that soon we will see a day when mining with a CPU or GPU just won’t cut it any longer, and the market will be dominated by FPGAs and specialized ASICs, bringing with them efficiency gains for proof of work, while also carelessly leading us all towards the next round of spending.
A perfect real-world example of the effect specialized hardware has had on the crypto-community was recently discovered involving a fairly new project called VerusCoin and a fairly new, relatively more economically accessible FPGA. The FPGA is designed to target specific alt-coins whose algo’s do not require RAM overhead. It was discovered the company had released a new algorithm, kept secret from the public, which could effectively mine Verus at 20x the speed of GPUs, which were the next fastest hardware types mining on the Verus network.
Unfortunately this was done with a deliberately secret approach, calling the Verus algorithm “Algo1” and encouraging owners of the FPGA to never speak of the algorithm in public channels, admonishing a user when they did let the cat out of the bag. The problem with this business model is that it is parasitic in nature. In an ecosystem where advancements can benefit the entire crypto community, this sort of secret mining approach also does not support the philosophies set forth by the Bitcoin or subsequent open source and decentralization movements.
Although this was not done in the spirit of open source, it does hint to an important step in hardware innovation where we could see more efficient specialized systems within reach of the casual miner. The FPGA requires unique sets of data called a bitstream in order to be able to recognize each individual coin’s algorithm and mine them. Because it’s reprogrammable, with the support of a strong development team creating such bitstreams, the miner doesn’t end up with a brick if an algorithm changes.
All is not lost thanks to.. um.. Technology?
Shortly after discovering FPGAs on the network, the Verus developers quickly designed, tested, and implemented a new, much more complex and improved algorithm via a fork that enabled Verus to transition smoothly from VerusHash 1.0 to VerusHash 2.0 at block 310,000. Since the fork, VerusHash 2.0 has demonstrated doing exactly what it was designed for- equalizing hardware performance relative to the device being used while enabling CPUs (the most widely available “ASICs”) to mine side by side with GPUs, at a profit and it appears this will also apply to other specialized hardware. This is something no other project has been able to do until now. Rather than pursue the folly of so many other projects before it- attempting to be “ASIC proof”, Verus effectively achieved and presents to the world an entirely new model of “hardware homogeny”. As the late, great, Bruce Lee once said- “Don’t get set into one form, adapt it and build your own, and let it grow, be like water.”
In the design of VerusHash 2.0, Verus has shown it doesn’t resist progress like so many other new algorithms try to do, it embraces change and adapts to it in the way that water becomes whatever vessel it inhabits. This new approach- an industry first- could very well become an industry standard and in doing so, would usher in a new age for proof of work based coins. VerusHash 2.0 has the potential to correct the single largest design flaw in the proof of work consensus mechanism- the ever expanding monetary and energy requirements that have plagued PoW based projects since the inception of the consensus mechanism. Verus also solves another major issue of coin and net hash centralization by enabling legitimate CPU mining, offering greater coin and hashrate distribution.
Digging a bit deeper it turns out the Verus development team are no rookies. The lead developer Michael F Toutonghi has spent decades in the field programming and is a former Vice President and Technical Fellow at Microsoft, recognized founder and architect of Microsoft's .Net platform, ex-Technical Fellow of Microsoft's advertising platform, ex-CTO, Parallels Corporation, and an experienced distributed computing and machine learning architect. The project he helped create employs and makes use of a diverse myriad of technologies and security features to form one of the most advanced and secure cryptocurrency to date. A brief description of what makes VerusCoin special quoted from a community member-
"Verus has a unique and new consensus algorithm called Proof of Power which is a 50% PoW/50% PoS algorithm that solves theoretical weaknesses in other PoS systems (Nothing at Stake problem for example) and is provably immune to 51% hash attacks. With this, Verus uses the new hash algorithm, VerusHash 2.0. VerusHash 2.0 is designed to better equalize mining across all hardware platforms, while favoring the latest CPUs over older types, which is also one defense against the centralizing potential of botnets. Unlike past efforts to equalize hardware hash-rates across different hardware types, VerusHash 2.0 explicitly enables CPUs to gain even more power relative to GPUs and FPGAs, enabling the most decentralizing hardware, CPUs (due to their virtually complete market penetration), to stay relevant as miners for the indefinite future. As for anonymity, Verus is not a "forced private", allowing for both transparent and shielded (private) transactions...and private messages as well"
If other projects can learn from this and adopt a similar approach or continue to innovate with new ideas, it could mean an end to all the doom and gloom predictions that CPU and GPU mining are dead, offering a much needed reprieve and an alternative to miners who have been faced with the difficult decision of either pulling the plug and shutting down shop or breaking down their rigs to sell off parts and buy new, more expensive hardware…and in so doing present an overall unprecedented level of decentralization not yet seen in cryptocurrency.
Technological advancements led us to the world of secure digital currencies and the progress being made with hardware efficiencies is indisputably beneficial to us all. ASICs and FPGAs aren’t inherently bad, and there are ways in which they could be made more affordable and available for mass distribution. More than anything, it is important that we work together as communities to find solutions that can benefit us all for the long term.
In an ever changing world where it may be easy to lose sight of the real accomplishments that brought us to this point one thing is certain, cryptocurrency is here to stay and the projects that are doing something to solve the current problems in the proof of work consensus mechanism will be the ones that lead us toward our collective vision of a better world- not just for the world of crypto but for each and every one of us.

Mining Bitcoin - The Coming Environmental Subsidy

Mining Bitcoin - The Coming Environmental Subsidy.
Mining Bitcoin incentives one to stake hardware and electricity in return for digital assets, which have or can have a market price that exceeds the cost of the electricity staked. Bitcoin is an uncorrelated hedge against the world economy, it’s programmable scarcity, not perceived scarcity, and is perhaps the hardest money the world has ever seen. Coming and developing second layer protocols for Bitcoin will execute transactions at the speed of light, and for virtually no cost. In time a decentralized economy will become our new reality, and networks will be owned by their users. There will be lighter weight consensus algorithms for most networks, but Proof Of Work, and in turn Bitcoin, will be the internets reserve currency, and what we peg the value of all decentralized networks to in the coming “Web 3” world. Bitcoin is here to stay, and Bitcoin mining presents a new opportunity in renewable energy.
Today, miners are moving as fast as they can to scale, lower their power cost, and decrease counter party risk. We are seeing a trend with miners setting up modular data centres behind the meter, tucked up to power plants that are located in areas where capacity is not in line with local demand, so miners become an obvious choice to churn through the surplus capacity of these plants. The issue here as it pertains to “environmental concern” is that miners cannot enter into energy purchase agreements (EPA’s) with plants that produce renewable power intermittently. So the result, we have mining farms finding blocks with coal or gas. Operators setting up such mining infrastructure often cite opportunity cost, which is definitely understandable, but irrespective of environmental hazard, the opportunity & economics of mining with fossil fuels will be short lived. Additionally these fossil fuel miners are beginning to face major counter party risk. Buying power to mine from major corporations, public utilities, or governments is convoluted and risky. Even one day without access to electricity can affect the bottom line, miners must begin thinking about energy independence. In the next 5 years setting up or sustaining a fossil fuel farm will be akin to thinking its a good idea to open and run a blockbuster video.
There are two major changes happening now in mining, and these changes will be the principal underwriters of Bitcoins coming “Environmental Subsidy”.
  1. Cost reductions in renewables & storage.
  2. The decentralization of mining.
In 2009 the global average cost to produce a Mwh of Solar was $350, in 2018 it was $50. The global average for coal production in 2018 was $100 per Mwh. Couple the declining cost bases for renewables with supportive policy and subsidies, and from a more macro POV its obvious where were going in terms of the type of energy that will be flowing into the grid. Although the sun doesn’t always shine and the wind doesn’t always blow, but there is a trend that is mitigating that - declining costs in storage. Today the average cost to the consumer of lithium ion storage is dropping rapidly, and multiple sources point to a cost base of $100 per Mwh or lower by 2025. In that not too distant future it is reasonable to speculate that we will see non grid tied mining ops running 24/7 - 365, whilst capturing and storing a surplus & finding blocks with their batteries.
Bitcoin mining is ironically centralized. Although with closer observation, we can see that mining centralization is the result of an expeditious technology adoption curve. In approximately 4-5 years miners went from CPUs, to GPUs, FPGAs, and now of course ASIC’s. These changes each represented more than 10,000X improvements, which meant that miners were completely writing down their hardware within 4-6 months. So to mine at scale in the earlier years, you basically needed direct access to a chip factory and massive capital. It made more sense for a hardware manufacturers to run their own hardware than to sell it, and in turn mining became centralized. Although were now close to the top of the hardware improvement curve, and will perhaps see improvements of 2X every 2 or 3 years going forward. So, with that being said, hardware manufactures have it in their best interest to sell their rigs, being that they no longer have the “chip advantage”. The plateau of mining hardware innovation marks the advent of mining decentralization.
In the coming years allocating some or all electricity generated at the point of production to mine Bitcoin, will allow one to amortize an investment in renewables sooner than if the power was sold into the grid. Bitcoin will become the reserve currency of the internet and as such de-risk the capital deployed in renewables when operators of renewable energy assets allocate some or all of their power to secure the Bitcoin blockchain. Electricity production will also become more decentralized as localized production and mini grids become complimentary to larger legacy points of production, which will in turn support the decentralization of mining. Our future energy needs will be met using renewables, and the same renewable power that heats our homes and charges our cars, will underpin the Bitcoin blockchain and the internet of money.

Transcript of Open Developer Meeting In Discord - 5/10/2019

[Dev-Happy] Blondfrogs05/10/2019
Channel should be open now
Chill05/10/2019
you all rock!
just getting that out of the way :wink:
Tron05/10/2019
Cheers everyone.
theking05/10/2019
Hi fabulous dev team!
Hans_Schmidt05/10/2019
Howdy!
Tron05/10/2019
No specific agenda today.
Questions?
Has everyone seen Zelcore wallet, and Spend app?
theDopeMedic05/10/2019
Any major development status updates that haven't been listed in #news?
Synicide05/10/2019
How was the meetup yesterday? I heard it would be recorded, it is uploaded anywhere yet?
Tron05/10/2019
And Trezor support on Mango Farm assets?
@Synicide Yes it was recorded. The Bitcoin meetup organizer has the video.
I talked about Ravencoin, but mostly about the stuff that was being built on/with/for Ravencoin.
There was about 70% overlap with folks who were at the Ravencoin meetup in March.
Synicide05/10/2019
awesome, looking forward to watching it when it's available
Tron05/10/2019
I'll hit up James and see if he's posting the video.
S1LVA | GetRavencoin.org05/10/2019
@theDopeMedic I'd follow github if youre interested in development status
Synicide05/10/2019
zelcore looks super slick. Been meaning to research its security more with the username/pw being stored on device
Chill05/10/2019
How is the progress on the restricted assets and testnet coming along? A secondary question would be about the approximate fork timeframe.
S1LVA | GetRavencoin.org05/10/2019
Has anyone heard from the community dev (BW) working on Dividends?
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Any word on BW and his progress w dividends?
@S1LVA | GetRavencoin.org LOL
Tron05/10/2019
@S1LVA | GetRavencoin.org Great question. I haven't heard.
Synicide05/10/2019
last meeting BlondFrogs said he would try to connect with BW as he was sick with the flu at the time. Maybe he has an update
S1LVA | GetRavencoin.org05/10/2019
I've tried to get in contact, but with no success.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Got a funny feeling...
Jeroz05/10/2019
Last time we left off with someone mentioning a foundation and Tron saying let’s discuss that next time iirc
kryptoshi05/10/2019
Has anyone taken a look at the merits for this proposal? Thoughts? https://medium.com/systems-nexus/modified-x16r-algorithm-proposal-for-constant-hash-rate-in-short-time-164711dd9044
Medium
Modified X16R algorithm proposal for constant hash rate in short time
Interpretation Lens V. a0.01
Tron05/10/2019
I did see it. Does anyone think this is a problem?
Synicide05/10/2019
It looks interesting... but I'm not sure what it is trying to solve. Looking at netstats, our 1 hour average block time is perfectly 1 minute
S1LVA | GetRavencoin.org05/10/2019
Last I heard from him he expressed how important finishing the code was. I wouldnt jump to conclusions on his absence within the community.
Synicide05/10/2019
x16r by nature will fluctuate, but DGW seems to be doing a good job keeping consistent block times
Tron05/10/2019
Because of relatively broad distribution across the algorithms, the block times are fairly consistent. It is possible, but very, very unlikely to get a sequence that takes up to 4x longer, but that's super rare, and only 4 minutes.
We did some timing analysis of the algorithms early on. A few are 1/2 as long as SHA-256 and some are up to 4x longer. But when you randomly select 16 it usually comes out about even.
Synicide05/10/2019
1hr avg: 1.02min - 24hr avg: 1min
I think we should focus on building, and not trying to fix what isnt necessarily broken
Tron05/10/2019
Agreed.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Agreed
Tron05/10/2019
Is everyone ok with the frequency (every other week) of this discussion?
Jeroz05/10/2019
(Added thumbs down to measure)
Tron05/10/2019
@Jeroz Did you do thumbs-up and thumbs down?
S1LVA | GetRavencoin.org05/10/2019
Seems appropriate. Its not like the devs dont poke around here and chat anyways.
Tron05/10/2019
Anything critical that we should be aware of?
Jeroz05/10/2019
When I need a dev, I poke a dev. When that dev is unavailable. I poke another one :smiley:
Hans_Schmidt05/10/2019
BlondFrogs was testing some github code last month to create a dividends snapshot database of asset holders at a given blockheight. Is that planned for inclusion? That's the only thing needed for dividends.
Jeroz05/10/2019
I hope I didn’t offend any devs
With poking around
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Was thinking voting would be an excellent use case for restricted assets. Local communities, nations, etc... could kyc their residents
radiodub05/10/2019
Is x16r will remain fpga mineable
Tron05/10/2019
@Jeroz We're hard to offend.
Chill05/10/2019
Is the general dev feeling that the next fork should and will include everything needed for the next 6-9 months (barring something completely unforeseen)?
Jeroz05/10/2019
I know :smile:
Tron05/10/2019
@radiodub Nearly impossible to stop FPGAs and still keep GPUs
Jeroz05/10/2019
About that: voting is another hard fork right? Not too soon?
Tron05/10/2019
FPGAs can be reprogrammed as fast. It is silicon (true ASIC) that we can obsolete with a tiny change.
@Jeroz Messaging, voting, Tags, Restricted Assets would require a hard fork (upgrade).
We could do them each individually, but folks get weary of upgrades, so current plan is to roll them together into one.
MrFanelli™05/10/2019
Good idea
Jeroz05/10/2019
Oh voting too?
MrFanelli™05/10/2019
People will like that
Jeroz05/10/2019
I thought that was coming later
Tron05/10/2019
Voting is the one that isn't being worked on now. Tags and Restricted assets have taken precedence.
Jeroz05/10/2019
I know. But you plan on waiting to fork until voting is also done?
That would have my preference tbh
But I can see an issue with too many things at the same time
Tron05/10/2019
If someone wants to step in, we've had one of our devs sidelined and he was working on BlockBook support so more light wallets can connect to Ravencoin. Mostly test cases needed at this point.
S1LVA | GetRavencoin.org05/10/2019
Thats a pretty large upgrade.. Bigger surface for unknowns
Rikki RATTOE Sr. SEC Impresantor05/10/2019
At what point would RVN community consider moving to ASICs because having a Bitcoin level of security would eventually be needed?
MrFanelli™05/10/2019
Never rikki
Tron05/10/2019
@S1LVA | GetRavencoin.org 100% Lots of testing on testnet and bounties.
[Dev-Happy] Blondfrogs05/10/2019
I am here :smiley:
Tron05/10/2019
@Rikki RATTOE Sr. SEC Impresantor There's nothing inherently wrong with ASICs but it tends to centralize to data centers and less opportunity for anyone to just run their gaming rig overnight and collect RVN.
Welcome Blondfrogs
MrFanelli™05/10/2019
Asics are too expensive. If we want normal people to mine, then we cant be an asic network
Rikki RATTOE Sr. SEC Impresantor05/10/2019
@Tron True but what happens when the chain needs a Bitcoin level of protection?
Tron05/10/2019
More GPUs, more FPGAs
MrFanelli™05/10/2019
Nvidia loves ravencoin :stuck_out_tongue:
Chill05/10/2019
ok, so we are pro FPGAs
𝕿𝖍𝖊 𝕯𝖔𝖓 𝕳𝖆𝖗𝖎𝖘𝖙𝖔 CEO ∞05/10/2019
Build it and they will come
Tron05/10/2019
It's all relative. It is cost to attack. If an ASIC isn't available for rent, then only option is rental of non-allocated GPUs
Rikki RATTOE Sr. SEC Impresantor05/10/2019
@Chill Eventually everyone will need FPGAs to be profitable on RVN, at that point I don't see why we just don't make the switch to ASICs
Tron05/10/2019
Also, as much as we don't focus on price, the price does matter because it determines the amount of electricity and hardware will be deployed to get the block reward. Price increase means more security, more mining means more security means higher price.
It's a circle.
Chill05/10/2019
someone tell that to the twitter handler
HailKira05/10/2019
you guys adding seedphrase to desktop wallet?
[Dev-Happy] Blondfrogs05/10/2019
@HailKira We will, just is not a high priority right now.
MrFanelli™05/10/2019
Twitter handle wants rvn ded
Rikki RATTOE Sr. SEC Impresantor05/10/2019
I just don't see much difference between ASIC and FPGA and I'd rather have the added nethash an ASIC will provide once GPUs are virtually kicked off the network
kryptoshi05/10/2019
I'm at 11 GB future proof
Tron05/10/2019
That also limits miners to big money, not gaming rigs.
Synicide05/10/2019
@Rikki RATTOE Sr. SEC Impresantor you have to keep in mind the 'added nethash' is all relative
Rikki RATTOE Sr. SEC Impresantor05/10/2019
FPGAs will limit miners to big $$$ too IMO
Tron05/10/2019
@kryptoshi New algo x16r-12G requires 12GB :frowning:
Seal <:cricat:> Clubber05/10/2019
But sperating smaller gb cards would lead to less adoption if we ever become a mainstream coin.
Adpotion of mining that is
Chill05/10/2019
but we are a mainstream coin
Seal <:cricat:> Clubber05/10/2019
Mains stream as in what eth did
Tron05/10/2019
@Rikki RATTOE Sr. SEC Impresantor I agree. Not a perfect solution.
Steelers05/10/2019
Is this a Dev meeting or Algo meeting :smiley:
Seal <:cricat:> Clubber05/10/2019
But if we ever go mem lane. We should aim for 6 or 8gb.
Tron05/10/2019
Open to other questions.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
@Tron Probably not the time and the place to have this discussion as we stand currently but IMO we're gonna have this conversation for real eventually
Seal <:cricat:> Clubber05/10/2019
Most cards have 6gb now.
kryptoshi05/10/2019
Why 12 gb ? Such a massive jump
Seal <:cricat:> Clubber05/10/2019
^
Would also like to know
Tron05/10/2019
@kryptoshi I was joking. You said you had 11GB card.
Seal <:cricat:> Clubber05/10/2019
Haha
You got em good
I cant imaghine the face he had when he was 1gb short
Lel
Rikki RATTOE Sr. SEC Impresantor05/10/2019
That's what she said
kryptoshi05/10/2019
Hahaha
MrFanelli™05/10/2019
need a 2080ti
Seal <:cricat:> Clubber05/10/2019
How much does the VII have?
16?
[Dev-Happy] Blondfrogs05/10/2019
Any other questions you have for us?
Hans_Schmidt05/10/2019
@[Dev-Happy] Blondfrogs You were testing some github code last month to create a dividends snapshot database of asset holders at a given blockheight. Is that planned for inclusion? That's the only thing needed for dividends.
Chill05/10/2019
a dev might want to contact Crypto Chico for some 'splaining
[Dev-Happy] Blondfrogs05/10/2019
I still haven't contacted the developer that was working on dividends. Was pretty busy with some other stuff. I will contact him this next week, and see where we are at for that.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Chico doesn't do interviews, shame. Tron would be a much needed interview for his community
[Dev-Happy] Blondfrogs05/10/2019
As far as releasing dividends, I can be released at anytime the code is finished and doesn't require any voting or hardfork to occur
kryptoshi05/10/2019
Android asset aware wallet?
Seal <:cricat:> Clubber05/10/2019
Is in beta right
Tron05/10/2019
Testing went well today on Android. Nearing release.
[Dev-Happy] Blondfrogs05/10/2019
as it is a mechanism that is wallet specific
liqdmetal05/10/2019
no protocol level dividends you guys are saying?
[Dev-Happy] Blondfrogs05/10/2019
correct
Tron05/10/2019
DM me if you want to test Android with Asset support. I'll send you the .APK.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
RVN gonna be on tZero wallet? :yum:
liqdmetal05/10/2019
why not? what is the logic on non-protocol dividends
assets + protocol dividends is nirvana
[Dev-Happy] Blondfrogs05/10/2019
dividends is pretty much sending payments to addresses. Right now, you would have to do this manually. The dividends code, will allow this to be done quicker and easier.
No consensus changes are required.
Tron05/10/2019
New Android wallet is BIP44 and original Android wallet is BIP32/BIP39 so the words will not find the funds. You'll need to send them to another wallet, and then send them to new BIP44 derived address.
liqdmetal05/10/2019
we already have payments to addresses
so dividends is not a feature so much as simple wallet script
Hans_Schmidt05/10/2019
@[Dev-Happy] Blondfrogs The dividend code changes look risky'er to me than messaging. Would you consider "tags" branch test-ready?
[Dev-Happy] Blondfrogs05/10/2019
Not yet @Hans_Schmidt
Dividends is easier then you would think if coded correctly. I still haven't seen the code from the community developer. Excited to view it though.
Hans_Schmidt05/10/2019
@[Dev-Happy] Blondfrogs Sorry- I meant restricted, not dividend
kryptoshi05/10/2019
@Tron on the Android wallet, anyone successfully added their own node and got it to sync faster? Always have issues. I have a supped up node and cannot get it to work with the Android wallet...
[Dev-Happy] Blondfrogs05/10/2019
@Hans_Schmidt Oh, that makes more sense. Yes, they are very risky! That is why we are going to create a new bug bounty program for restricted assets testing.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Once the network does get flooded w FPGAs, should we even consider changing the algo a couple times a year? That would only give bitstream developers added time to hoard their creations for themselves
Kind of like they're already doing with their x16r bitstreams :yum:
kryptoshi05/10/2019
Flooded... lol... like that hardware has mass production scale like gpus...come on dude
MrFanelli™05/10/2019
Bip44 wallet? :smiley:
Rikki RATTOE Sr. SEC Impresantor05/10/2019
@kryptoshi Eventually yes, where there's $$$ to be made, people make things happen
MrFanelli™05/10/2019
So can we trade from that in the new Binance Dex when RVN get listed?
kryptoshi05/10/2019
@Rikki RATTOE Sr. SEC Impresantor Yes Soon TM lol. :soontm:
Tron05/10/2019
@kryptoshi There are some things we can do to speed it up. For a new wallet, it shouldn't need to sync. For recovered wallet, it needs to sync from beginning of BIP44 wallet support on iOS so words can be moved between the two.
Other options include grabbing the first derived address and looking it up on an explorer to see when it was first used and sync from there.
Another option is to add an optional number with the 12 words so it knows when to start syncing.
There isn't a good reason on an SPV wallet to sync before the seed was created.
kryptoshi05/10/2019
Cool. Glad you are looking at speedup options.. :right_facing_fist: :left_facing_fist:
[Dev-Happy] Blondfrogs05/10/2019
@MrFanelli™ If the binance dex support RVN deposits. I am sure you would be able to send from it
MrFanelli™05/10/2019
Has binance reached out for any info or anything?
I seen that we ranked in some voting competition they had on twitter
for an ama
Rikki RATTOE Sr. SEC Impresantor05/10/2019
I believe we'll need to create a fund of approximately $300,000 in order to get a BNB-RVN asset created and listed on the Binance FDEX
[Dev-Happy] Blondfrogs05/10/2019
In order to work with binance we need Ravencoin integrated into Blockbook.
Tron05/10/2019
@MrFanelli™ I've reached back out to Binance on the AMA.
MrFanelli™05/10/2019
Awesome :smile:
kryptoshi05/10/2019
@Tron you are a natural on the interviews... cool as a cucumber. :sunglasses:
Tron05/10/2019
Thanks @kryptoshi
[Dev-Happy] Blondfrogs05/10/2019
Cool. We are done for today.
Please don't ask us any more questions :smiley:
Tron05/10/2019
Thanks everyone!!!!

The Problem with PoW

The Problem with PoW

Miners have always had it rough..
"Frustrated Miners"


The Problem with PoW
(and what is being done to solve it)

Proof of Work (PoW) is one of the most commonly used consensus mechanisms entrusted to secure and validate many of today’s most successful cryptocurrencies, Bitcoin being one. Battle-hardened and having weathered the test of time, Bitcoin has demonstrated the undeniable strength and reliability of the PoW consensus model through sheer market saturation, and of course, its persistency.
In addition to the cost of powerful computing hardware, miners prove that they are benefiting the network by expending energy in the form of electricity, by solving and hashing away complex math problems on their computers, utilizing any suitable tools that they have at their disposal. The mathematics involved in securing proof of work revolve around unique algorithms, each with their own benefits and vulnerabilities, and can require different software/hardware to mine depending on the coin.
Because each block has a unique and entirely random hash, or “puzzle” to solve, the “work” has to be performed for each block individually and the difficulty of the problem can be increased as the speed at which blocks are solved increases.
Hashrates and Hardware Types
While proof of work is an effective means of securing a blockchain, it inherently promotes competition amongst miners seeking higher and higher hashrates due to the rewards earned by the node who wins the right to add the next block. In turn, these higher hash rates benefit the blockchain, providing better security when it’s a result of a well distributed/decentralized network of miners.
When Bitcoin first launched its genesis block, it was mined exclusively by CPUs. Over the years, various programmers and developers have devised newer, faster, and more energy efficient ways to generate higher hashrates; some by perfecting the software end of things, and others, when the incentives are great enough, create expensive specialized hardware such as ASICs (application-specific integrated circuit). With the express purpose of extracting every last bit of hashing power, efficiency being paramount, ASICs are stripped down, bare minimum, hardware representations of a specific coin’s algorithm.
This gives ASICS a massive advantage in terms of raw hashing power and also in terms of energy consumption against CPUs/GPUs, but with significant drawbacks of being very expensive to design/manufacture, translating to a high economic barrier for the casual miner. Due to the fact that they are virtual hardware representations of a single targeted algorithm, this means that if a project decides to fork and change algorithms suddenly, your powerful brand-new ASIC becomes a very expensive paperweight. The high costs in developing and manufacturing ASICs and the associated risks involved, make them unfit for mass adoption at this time.
Somewhere on the high end, in the vast hashrate expanse created between GPU and ASIC, sits the FPGA (field programmable gate array). FPGAs are basically ASICs that make some compromises with efficiency in order to have more flexibility, namely they are reprogrammable and often used in the “field” to test an algorithm before implementing it in an ASIC. As a precursor to the ASIC, FPGAs are somewhat similar to GPUs in their flexibility, but require advanced programming skills and, like ASICs, are expensive and still fairly uncommon.
2 Guys 1 ASIC
One of the issues with proof of work incentivizing the pursuit of higher hashrates is in how the network calculates block reward coinbase payouts and rewards miners based on the work that they have submitted. If a coin generated, say a block a minute, and this is a constant, then what happens if more miners jump on a network and do more work? The network cannot pay out more than 1 block reward per 1 minute, and so a difficulty mechanism is used to maintain balance. The difficulty will scale up and down in response to the overall nethash, so if many miners join the network, or extremely high hashing devices such as ASICs or FPGAs jump on, the network will respond accordingly, using the difficulty mechanism to make the problems harder, effectively giving an edge to hardware that can solve them faster, balancing the network. This not only maintains the block a minute reward but it has the added side-effect of energy requirements that scale up with network adoption.
Imagine, for example, if one miner gets on a network all alone with a CPU doing 50 MH/s and is getting all 100 coins that can possibly be paid out in a day. Then, if another miner jumps on the network with the same CPU, each miner would receive 50 coins in a day instead of 100 since they are splitting the required work evenly, despite the fact that the net electrical output has doubled along with the work. Electricity costs miner’s money and is a factor in driving up coin price along with adoption, and since more people are now mining, the coin is less centralized. Now let’s say a large corporation has found it profitable to manufacture an ASIC for this coin, knowing they will make their money back mining it or selling the units to professionals. They join the network doing 900 MH/s and will be pulling in 90 coins a day, while the two guys with their CPUs each get 5 now. Those two guys aren’t very happy, but the corporation is. Not only does this negatively affect the miners, it compromises the security of the entire network by centralizing the coin supply and hashrate, opening the doors to double spends and 51% attacks from potential malicious actors. Uncertainty of motives and questionable validity in a distributed ledger do not mix.
When technology advances in a field, it is usually applauded and welcomed with open arms, but in the world of crypto things can work quite differently. One of the glaring flaws in the current model and the advent of specialized hardware is that it’s never ending. Suppose the two men from the rather extreme example above took out a loan to get themselves that ASIC they heard about that can get them 90 coins a day? When they join the other ASIC on the network, the difficulty adjusts to keep daily payouts consistent at 100, and they will each receive only 33 coins instead of 90 since the reward is now being split three ways. Now what happens if a better ASIC is released by that corporation? Hopefully, those two guys were able to pay off their loans and sell their old ASICs before they became obsolete.
This system, as it stands now, only perpetuates a never ending hashrate arms race in which the weapons of choice are usually a combination of efficiency, economics, profitability and in some cases control.
Implications of Centralization
This brings us to another big concern with expensive specialized hardware: the risk of centralization. Because they are so expensive and inaccessible to the casual miner, ASICs and FPGAs predominantly remain limited to a select few. Centralization occurs when one small group or a single entity controls the vast majority hash power and, as a result, coin supply and is able to exert its influence to manipulate the market or in some cases, the network itself (usually the case of dishonest nodes or bad actors).
This is entirely antithetical of what cryptocurrency was born of, and since its inception many concerted efforts have been made to avoid centralization at all costs. An entity in control of a centralized coin would have the power to manipulate the price, and having a centralized hashrate would enable them to affect network usability, reliability, and even perform double spends leading to the demise of a coin, among other things.
The world of crypto is a strange new place, with rapidly growing advancements across many fields, economies, and boarders, leaving plenty of room for improvement; while it may feel like a never-ending game of catch up, there are many talented developers and programmers working around the clock to bring us all more sustainable solutions.
The Rise of FPGAs
With the recent implementation of the commonly used coding language C++, and due to their overall flexibility, FPGAs are becoming somewhat more common, especially in larger farms and in industrial setting; but they still remain primarily out of the hands of most mining enthusiasts and almost unheard of to the average hobby miner. Things appear to be changing though, one example of which I’ll discuss below, and it is thought by some, that soon we will see a day when mining with a CPU or GPU just won’t cut it any longer, and the market will be dominated by FPGAs and specialized ASICs, bringing with them efficiency gains for proof of work, while also carelessly leading us all towards the next round of spending.
A perfect real-world example of the effect specialized hardware has had on the crypto-community was recently discovered involving a fairly new project called VerusCoin and a fairly new, relatively more economically accessible FPGA. The FPGA is designed to target specific alt-coins whose algo’s do not require RAM overhead. It was discovered the company had released a new algorithm, kept secret from the public, which could effectively mine Verus at 20x the speed of GPUs, which were the next fastest hardware types mining on the Verus network.
Unfortunately this was done with a deliberately secret approach, calling the Verus algorithm “Algo1” and encouraging owners of the FPGA to never speak of the algorithm in public channels, admonishing a user when they did let the cat out of the bag. The problem with this business model is that it is parasitic in nature. In an ecosystem where advancements can benefit the entire crypto community, this sort of secret mining approach also does not support the philosophies set forth by the Bitcoin or subsequent open source and decentralization movements.
Although this was not done in the spirit of open source, it does hint to an important step in hardware innovation where we could see more efficient specialized systems within reach of the casual miner. The FPGA requires unique sets of data called a bitstream in order to be able to recognize each individual coin’s algorithm and mine them. Because it’s reprogrammable, with the support of a strong development team creating such bitstreams, the miner doesn’t end up with a brick if an algorithm changes.
All is not lost thanks to.. um.. Technology?
Shortly after discovering FPGAs on the network, the Verus developers quickly designed, tested, and implemented a new, much more complex and improved algorithm via a fork that enabled Verus to transition smoothly from VerusHash 1.0 to VerusHash 2.0 at block 310,000. Since the fork, VerusHash 2.0 has demonstrated doing exactly what it was designed for- equalizing hardware performance relative to the device being used while enabling CPUs (the most widely available “ASICs”) to mine side by side with GPUs, at a profit and it appears this will also apply to other specialized hardware. This is something no other project has been able to do until now. Rather than pursue the folly of so many other projects before it- attempting to be “ASIC proof”, Verus effectively achieved and presents to the world an entirely new model of “hardware homogeny”. As the late, great, Bruce Lee once said- “Don’t get set into one form, adapt it and build your own, and let it grow, be like water.”
In the design of VerusHash 2.0, Verus has shown it doesn’t resist progress like so many other new algorithms try to do, it embraces change and adapts to it in the way that water becomes whatever vessel it inhabits. This new approach- an industry first- could very well become an industry standard and in doing so, would usher in a new age for proof of work based coins. VerusHash 2.0 has the potential to correct the single largest design flaw in the proof of work consensus mechanism- the ever expanding monetary and energy requirements that have plagued PoW based projects since the inception of the consensus mechanism. Verus also solves another major issue of coin and net hash centralization by enabling legitimate CPU mining, offering greater coin and hashrate distribution.
Digging a bit deeper it turns out the Verus development team are no rookies. The lead developer Michael F Toutonghi has spent decades in the field programming and is a former Vice President and Technical Fellow at Microsoft, recognized founder and architect of Microsoft's .Net platform, ex-Technical Fellow of Microsoft's advertising platform, ex-CTO, Parallels Corporation, and an experienced distributed computing and machine learning architect. The project he helped create employs and makes use of a diverse myriad of technologies and security features to form one of the most advanced and secure cryptocurrency to date. A brief description of what makes VerusCoin special quoted from a community member-
"Verus has a unique and new consensus algorithm called Proof of Power which is a 50% PoW/50% PoS algorithm that solves theoretical weaknesses in other PoS systems (Nothing at Stake problem for example) and is provably immune to 51% hash attacks. With this, Verus uses the new hash algorithm, VerusHash 2.0. VerusHash 2.0 is designed to better equalize mining across all hardware platforms, while favoring the latest CPUs over older types, which is also one defense against the centralizing potential of botnets. Unlike past efforts to equalize hardware hash-rates across different hardware types, VerusHash 2.0 explicitly enables CPUs to gain even more power relative to GPUs and FPGAs, enabling the most decentralizing hardware, CPUs (due to their virtually complete market penetration), to stay relevant as miners for the indefinite future. As for anonymity, Verus is not a "forced private", allowing for both transparent and shielded (private) transactions...and private messages as well"
If other projects can learn from this and adopt a similar approach or continue to innovate with new ideas, it could mean an end to all the doom and gloom predictions that CPU and GPU mining are dead, offering a much needed reprieve and an alternative to miners who have been faced with the difficult decision of either pulling the plug and shutting down shop or breaking down their rigs to sell off parts and buy new, more expensive hardware…and in so doing present an overall unprecedented level of decentralization not yet seen in cryptocurrency.
Technological advancements led us to the world of secure digital currencies and the progress being made with hardware efficiencies is indisputably beneficial to us all. ASICs and FPGAs aren’t inherently bad, and there are ways in which they could be made more affordable and available for mass distribution. More than anything, it is important that we work together as communities to find solutions that can benefit us all for the long term.
In an ever changing world where it may be easy to lose sight of the real accomplishments that brought us to this point one thing is certain, cryptocurrency is here to stay and the projects that are doing something to solve the current problems in the proof of work consensus mechanism will be the ones that lead us toward our collective vision of a better world- not just for the world of crypto but for each and every one of us.

Open Source FGPA Bitcoin MinerJust released was the Open Source FPGA Bitcoin Miner software. This miner allows bitcoins to be mined using a commercially available FPGA board. FPGA boards consume much less electricity compared to GPUs for the hashing work performed when mining bitcoins. The Field Programmable Gate Array (or FPGA for short) are effectively mining rigs that can be quickly programmed with a good deal of speed and ease. If there was ever a need for a dedicated mining network to spontaneously change the makeup of its algorithm, FPGA can make the changes needed.
