[WTS] Access to my Twitter bot that wins you contests online for $5 in BTC

Over the past two years, I have been running a twitter bot whose sole purpose is to enter contests. It has taken lots of trial and error, but I'm finally comfortable enough to start allowing others to use it.
The way it works is pretty simple. It searches twitter for tweets that match the phrase "retweet to win". It will gather as many as those tweets as it can and check if the tweet requires the user to like the tweet and follow the user as well.
A huge hurdle I've had to overcome is Twitter's limitations. Twitter only allows bots to search, follow, retweet, and like a certain amount of tweets in a single day. For that reason, I have the bot set up to act as human as possible by entering the contests throughout the day.
Another issue I've had to overcome is the sheer amount of fake contests/scams there are on twitter. I try and filter out as much as possible, and when everything is said and done, my bot is entering just over 150 contests per day. Filtering out the scams is an ongoing process.
I've won quite a few things, and to be honest, most of it is crap. I win a lot of useless stuff that I wouldn't ever use so I either decline the prize or try and sell it. However, over the two year time period, I can tell you about some of the more interesting things I've won:
  1. Signed baseball by former Yankee's first baseman, Don Mattingly
  2. Bitcoin Mining Rig that I was able to sell on ebay for $700
  3. Many books (lots of them signed by the author)
  4. Shirts, socks, sweaters, etc.
  5. NBA tickets (suite level)
  6. Concert tickets (3-4 different times)
  7. Tickets to Cirque Du Soleil
  8. Essential Oil set worth $100
  9. $10 Playstation Network Gift Card
  10. $25 Nintendo Switch Gift Card
  11. Etsy Jewelry
  12. Xbox Live Gold 3-Month Membership
  13. Steam Account with over 100 games
  14. Sports Jersey
  15. Tactical Flashlight
  16. Tape Measure (yeah I know, weird)
  17. $20 credit to some shady online casino which I turned into $50 and cashed out
  18. $265 Purse
These are some of the more memorable things I've won but there are many more. My bot has entered somewhere near 30,000 contests on my account, so it's really just a numbers game.
Because of ongoing servehosting costs, this is a recurring service. Once you connect your twitter account, it is completely automated and you don't need to do anything except check your twitter to see if you've won anything.
I will give you 1 month access (30 days) for $5 USD (Paypal or Bitcoin), although I recommend using the service for longer to increase your chances of winning something really cool. For that reason I also offer a year (365 days) of this service for $50 USD.
There is no guarantee you will win anything. This is simply an automated service that will automate your twitter account. I am limiting this service to a select few to ensure my server can handle the extra load.

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!

Just dropped out of school and got some money, can't wait to get started!

My friend was telling me about how bitcoin was worth almost 20k last month, and I saw Keemstar make some money. So I decided to invest. I had to sacrifice my scholarship and my car but I was able to get 5 1050ti's for only $600 each! I'm going to start next month once I move back in with my parents, hopefully I can get them to pay the electric bill for maximum profits lol.
A couple of questions.
How do I mine the blockchain?
How much is bitcoin right now?
Where is the bitcoin bank?
What is a ethereum?
Can I mine without internet?
I was reading that somepeople were using oil to cool their rigs? Can I just use some oil from the gas station or do I need cooking oil?
How much bitcoins will i make a day? 40-60? Or something like 100?
Will god save me?
Thanks!

Up to $120 bounties for answering altcoin mining questions

I'm thinking about sinking some major money into mining. Probably $15,000 to $20,000. Not all up front but sliding into it pretty quickly.
I've got about three rigs up and running with ethereum but I have several issues I want input on. I am setting aside a $40 bounty for the three top answers ($20 for the top, two $10 for the runner ups) paid in bitcoins. I will be posting this in several places.
If there is a REALLY good answer I will offer an additional $80 (total of $100) for the top answer. This is my research that may save me from making a big mistake.
I live in the Midwest with temperature that hits 100f / 38c for 3 to 4 consecutive months a year. I want to run this operation in my garage.
Cooling. This is by far my biggest concern. I live in the Midwest with three months of 100f / 38c per year. I've dealt with this before with litecoin. I don't want to have to air condition. In my previous experience fans aren't adequate.
Will this gpu be able to stay cool at the temps I've mentioned without air conditioning?
http://www.newegg.com/Product/Product.aspx?Item=N82E16814131676
If not … does anyone have experience using dialetric fluid / oil to submersible the cards in? I'm going to have to cool the oil somehow right? Is there a book way to do this? (Drop sealed containers of ice in the vat, pump it thru an oil radiator?
Hardware. As linked above I'm leaning towards the 390X to try to retain value a year from now. I'm thinking of using this motherboard
http://www.amazon.com/ASRock-Motherboard-H81-PRO-BTC/dp/B00HEUIS2G
USB risers. http://www.ebay.com/itm/Powered-PCI-E-Express-1X-To-16X-Extender-Riser-Card-With-60CM-USB-3-0-Cable-/301105921855?hash=item461b4fbf3f:g:oGMAAMXQuTNTMSBV
Mining. Has anyone developed a proprietary ether miner they are selling? Has vertcoin or monero mining stayed profitable with a .09 kw electric rate between the litecoin dropout and today if you are able to get a good cooling (non ac) system in place?
Power. I'm leaning towards this as my PSU. http://holybitcoin.com/product/dps-2000bb-breakout-adapter-board/ (I know I'll have to install a fan for the PSU). I'm fairly comfortable with the electric side of things until it gets to the PSU (I understand amps, volts, watts, and required wire gauges. Any warnings on running server PSUs?

Blockchain summit report: Day 1 - "Enterprise cloud"

previous days
`
Event details
Today was day 1 of the 2 day "International Blockchain summit" presentations. On every seat was a little bag that had 3 books about the Blockchain! Unfortunately they were all in Chinese.
http://imgur.com/jmkRYVj http://imgur.com/g66KeRD
`
Presentations summary
Whereas DEVCON2 was all about development, and leveraging the network effects of leveraging other projects in the ecosystem, the presentations today were VERY high level talks.
There was a massive stark difference between "the old guard" in the Fintech space, and the disruptors that are shaking things up.
Take a look at the BOC (Bank of China) and ChinaLedger presentations. They talk about how Distributed computing is dangerous. ChinaLedger go on to say that they need the power to be able to go in and halt transactions, modify smart contracts on the fly, liquidate accounts when they need. While also saying that they will make sure they will do everything to help privacy and use encryption… which only the Government can unlock ("Golden keys"?). It was the most centralised "Blockchain" I have ever heard of.
On the flip side I was inspired by the forward thinking of the Consensys presentation, and their long term vision for where to drive the Ethereum platform. They are helping to create open tools and platforms that will be leveragable by a multitude of projects (as demonstrated with Ujo and BHP project "Rai stones").
http://imgur.com/AXHw1Df
After the Consensys presentation, my 2nd favourite presentation was by Wanxiang labs "10 years to build a city", talking about how they plan on taking some land and creating from scratch a smart city powered by the blockchain and electric vehicles. While the other old guard are squabbling about how it is going to impact their "business as usual" profits, there were the new projects out there envisioning and disrupting.
The BHP presentation was also pretty cool, a great implemenation of using Blockchain to improve a business process.
`
Presentations
New Finance: Technical & Legal rules - BoC He is from bank of China. Entire presentation was him being scared and trying to justify why current Blockchain tech is an unregulated wasteland, and why there needs to be regulation from banks and government.
For Fintech they think Blockchain will not be successful without proper regulations Blockchain finance - it is distributed. Storing all of the transactions will take a lot of storage space. What to do once the transaction rates exceed what can be processed. Thinks that public distributed transactions will not be more than a toy like with Bitcoin. For real FinTech they need something different for a high frequency. Thinks that decentralisation should not be the core feature of Blockchains (due to transaction limit). Thinks it should be decentralised, not distributed.
Should be done with private consortiums. Needs legal rules and technical rules. They think that self rulemaking currencies (Bitcoin) can not be regulated. So need to stop them, to prevent bad things like money laundering. This is showing the loopholes brought about by Bitcoin. So when using digital currencies, they need certifications and tracking.
"We need more regulations and rules to facilitate the healthy development of this space. Only with support of regulations can new technology take off".
Me: I totally disagree… (if not already apparent)
Blockchain futures & realities - CSDC
China Securities Depository and clearinghouse
He was much more open minded and forward looking. Is a pep talk for "things are going to change", how are we going to use these new things. He said that he recorded it into English that should be able to be downloaded, would be worth watching if you are into this space.
Summary: Genie is out of the bottle, we need to embrace this and think how we are going to put the requirements of securities ("real name transactions") in a decentralised way. And the registration and tracking of assets to real names.
People have ideals because they are not happy with reality. Due to this dissatisfaction, people are passionate about trying to make that dream a reality. Need to play by the rules, or the market will be chaos. So now we have facilities law, regulations, etc. This forms the framework of China economic. This is very different from Blockchain. This is at odds to the distributed systems. Seems like we are dissatisfied with this, so trying to reconcile these differences.
All securities transactions need to follow "real name" transactions, but want to do this in a decentralised manner. Market cap is 54 trillion (of something in China). GDP is over 70 million
They are researching Blockchain, but not just in the lab. Need to find potential applications and use cases for it. If we want to implement Blockchain technologies, we need to see what the hurdles will be, so we can get closer to the ideal. As BoC speaker said, the number of transactions per seconds is HUGE. Daily may reach 10s of millions at its peak. How are we going to handle this with a theoretical framework. Need to start from the reality of China. And the reality is it is a giant country with a huge population, which depends on the capital market. If you just implement within a lab it is okay. But if it is going to be put into the industry, then we need to work with the government. We can't just get rid of the government, it is impossible (REVOLUTION!!). So need to focus on key senarios to tackle, as you can't just apply Blockchain everywhere simultaneously. Or all your efforts will fruitless. How to complement it initially, not replace it.
Ten years efforts to build a city (Wanxiang Labs)
Me: I reallly liked this presentation. I've been keeping notes for months around building this type of innovative city in Australia. I plan on rewatching this one again later.
Going to build a city in 10 years. An energy gathering city in HangZhou 10KM2. Their US company is starting to build new energy vehicle. 900m RMB? 90k people. Deploy the city into the cloud. Intelligent life, traffic & services. Everything will be connected. IoT, Internet, smart living, smart transport. Once this is successful, they plan on launching it across the world. Will publish their learnings. Launching incubators and accelerators. Their own cloud Blockchain as a Service. Many scenarios in this smart city that could utilise Blockchain. Distribution for Solar power. ID & Vehicle registration. Intelligent community services. Can promote a sharing economy throughout the community. Partnering with Microsoft, IBM, Consensys, Ethereum foundation, WeBank, AliCloud
Vitalik Buterin keynote
Talking of the progress China has made in Blockchain innovation in such a short period of time. He visited China 3 years ago and visited a number of Bitcoin companies and was impressed on the scale of what China had, much more than what was happening in USA. But all the focus was just on cryptocurrencies, not Blockchain technologies, Just mining. 2nd time, he saw some kind of experimentation happening with interesting things (like coloured coins?) 3rd time saw more interest in Blockchains. 4th? time, he did a hackathon with Wanxiang labs (event sponsor), and there were ~30 projects. The growth since then has been rapidly growing. The scale of projects we couldn't have imagined 3 years ago. Was just theoretical, now a lot of ideas are almost reality. e.g. Self-sovereign identity, instant settlement.
Hyperledger
https://www.hyperledger.org/ Goals. Build an opensource dev focused community of communities to build a hyperledger based solution. Create a family of "etnerprise grade" open source blockchain framework, platform & libraries.
Because it is an enterprise opensource project, they need to track contributions, patent details, etc. Is part of the Linux Foundation, which has 16 years of providing governance stucture support for major open source projects. 80 project partners. IBM, Intel, Accenture, JP Morgan, Airbus, ANZ bank, Cisco, etc. 20 of the 80 project partners, are based in China. Apache license v2.
A world or many chains. There will not be only one blockchain. There will be many public chians and millions of private chains. Each may use different consensus mechanisms.
Major projects are: Fabric: Developed by IBM. PBFT, moving to Raft and other pluggable consensus mechanisms. Written in Go. Sawtooth Lake: Proof of Elapsed Time. Runs on secure enclaves. Written in Python. Hyperledger explorer: GUI for navigating Fabric & swatooth lake. Fabric-py SDK. (Java proposed later).
Future: Smart contract engines. Portable identities. Will never see a "HyperCoin". It is about making Hyperledger a standard, and a governance group.
IBM keynote - IBM Blockchain & Hyperledger
Today if you want to do something in your business on Blockchain it is difficult. Hard to scale, issues with privacy. No Enterprise support. Need tools to write tests for smart contracts. Need good solution patterns. Difficult to scale up, especially around transaction rates.
Built Fabric to support "serious business" Permissioned blockchains can't scale. Every node shouldn't execute every transaction. The 2 peers that are interacting are the only ones that should execute. IBM has implemented this internally to resolve invoice disputes with their suppliers.

All the slides were in Chinese. Difficult to follow unfortuantely. The (original) Silk Road was important for trade. Blockchain may be just as important for trade in the future People are debating the need of distributed systems being an important thing of Blockchains, is it really necessiary? Blockchain should instead be focused on unblocking instead. IBM will provide an IBM certified docker container. IBM Blockchain. http://www-31.ibm.com/ibm/cn/blockchain/index.html Has a concept of a "shadow chain"?
Blockchain Platform @ Microsoft
At Devcon1 Microsoft announced Blockchain as a Service. Rolled out DevTest Labs to allow you to spin up public, private, permissioned, and consotrium blockchians quickly. Provisoin with 1 click. Mix & match from best available blockchain tech.
Bletchley: Open infrastructure, Enterprise capabilities. Microsoft is not building their own Blockchain.
Blockchain has some missing parts (identity, privacy, key management lifecycle, tools). Asked our partners what are the missing parts. A database in itself isn't an application.
(re)Announcing: Bletchley v1. 2 parts. Distributed infrastructure layer (Blockapps, R3, bitpay, parity, Eris). There isn't going to be 1 Blockchain to rule them all, so allow you to leverage any of them. Lots of customers were taking a long time trying to spin up private consortiums, and trying to secure them correctly. Used to take 3 weeks, now down to 8 questions and 5 minutes. Spins up a private Ethereum consortium. 4-100s of nodes.
Distributed middleware "fabric" layer. Tools that can work across many blockchain technologies. Cryptlets are a way of doing offchain processing. Receive market data based on an event (market price daily closing, CRM event). Need to have trusted execution of the logic, to attest that it was not tampered with. Secure IP protected algorithms. Scale an algorithm for max performance by running it off blockchain in a secure & attested way in the cloud. Oracles may be malicious, or they may be intercepted during transmission. Cryptlets run on a secure host with a secure communication channel in a trust envelope. Marketplace for publishing the cryptlets into a market for others to consume. Azure cloud is twice the size of Amazon & Google COMBINED.
Bletchley Cryptlet Fabric. Supports Ethereum, will support more Blockchains. It is middleware that will support many. Secure execution on demand. Standard way of publishing and accessing external resources.
BaaS roadmap. DevTest labs, will continue to onboard more. Bletchley v1. Kinakuta to help improve security. Bletchley SDK
Longer range implications of Ethereum & other decentralising technologies (Consensys) LOVED this presentation.
Simplest view: Next gen database. Blockchain based, maximal replication, Prevents rogue actors Force for universal disintermediation, will distrupt every industry. Previously it was mostly just Bitcoin. Future projects were "BitCoin 2.0", instead of "Blockchain 2.0". So Ethereum project built the most powerful and capable Blockchain platform, both public (permisionless) and private (permissioned) Deeply secure, non-repudiable shared source of truth. Dapp is a set of smart contracts. And a user interface to interact with it. Was important to get an initial version of Ethereum out into the hands of devs, to start thinking how to start building decentralised applications. Ethereum has a vision for scalability, which includes sharding and state channels. Privacy, state channels is one option. Zcash/zk-Snarks is another way.
Currently building out an ecosystem of decentralised applications. Building core components: Identity/persona (uPort, metamask). Wallet (uPort wallet). Registries (Regis, ENS). Token Factory. Do private enterprise Blockchains make sense? Yes, large entities can have a complex internal mix of business units, having a shared source of truth can help. If enterprises have their own private consortium Blockchains, will be a harder target to infiltrate and modify databases. Business processes emboided as state transition graphs.
If you plan on building your own tools or technology on top of Blockchain tech (public or private), build it on Ethereum so it can be reused in many different places by other entities running their private chains Developed "Balance" for real time compliance, accounting auditing and monitoring. Real time dashboard for companies & regulators. Organisations using certified software wil not be able to break or bend any financial accounting rules.
The Blockchain will last for years or decades giving a persistent database. Gives a chance to do persistent portable identity. uPort self-sovereign identity.
Blockapps Announcement
Is Ethereum for Enterprise. Partnered with Microsoft to announce Blockchain as a Service (BaaS). Over 1k projects have used it, over 300 customers. Being released in Azure China datacentre (mooncake), and other Chinese clouds : Alibaba cloud, tencent cloud, Wancloud. Initial China projects: Minsheng insurance, Wanxiang smart city, Qianhai smart city, Shanghai smart city. China is going to be the country leading the world in Blockchain projects.
The Rise of Blockchain Consortia: Uniting the Banking World
One of the largest banks in Spain. Banks are just a ledger (a very large ledger). Each bank has its own ledger. They don't trust each others. Which is why you need clearing houses and things like this. What if there was a shared ledger trusted by all banks. "It's not about the coin, its about the ledger.
`
New development of ChinaLedger: Forging a powerful tool for Chinese capital market in the FinTech era
Was literally the most centralised blockchain I have ever heard of. Please excuse me as I rant inline.
ChinaLedger is a consortium. 11 founders established it. Chinese financial institutions and Wanxiang labs. "we created our own Blockchain and tools". Will come up with their own custom software and implementation. Will create a whitepaper and create reference architecture. Partners will use the network to do transactions. Need facilities to be able to freeze or take over acounts, and get access to all data. A need to be able to halt or freeze a transaction or smart contract. A need to be able to halt or freeze a transaction or smart contract. and the facility to liquidate an account or smart conract or manually change the state of a smart contract We need to be able to stop the trading of certain stocks. Let regulators control things. Will be fully in control of the gas. Wants to support 100k/s and 1 ms latency.
Then ironically says tries to say they are going to put privacy into this. "Everything will be encrypted and private. Except that CCP & regulators who will have ability to read everything". I'm SURE that won't be abused…
http://imgur.com/Qt4qh3O You keep using that word... Blockchain, distributed ledger, privacy, encryption
Re-imagining Global Payments (For business)
Banks make a LOT of money from bank wires. So they have no incentive to come up with anything better. The person sending the money needs to give 26 pieces of information. Don't know when you'll get the money, what the rate will be. About $20 to send, $20 to receive, plus lose a few percentage through the conversion.
Their solution (for business payments). Register for an account, can use online. No fees. Transparent FX rate. Can track the payment. Uses Bitcoin in the middle. Before international calls used to call many $s per minute. Now with VoIP (Skype) you can do it for cents. Same thing will happen to international money transfers.
Enabling Global P2P Cash Transfers with Abra (For consumer)
https://www.goabra.com/ http://www.coindesk.com/abra-remittance-app-us-launch/
Nowadays you can send an IM to anyone else in the world instantly for free. Why can't you do the same thing with money? Can do it locally in some domestic markets, like paytm (india, WeChat pay (China), mpesa (Africa). But not for cross border transactions. iOS & Android. Real digital cash wallet. Send & receive globally. No FX risk. Add cash via bank or in person. As private as paper cash. Abra tellers earn $$ (as a percentage fee). The wallet is stored locally on the phone. So you "physically" control it. (need to back up your private key). Use an Abra teller (someone else using the app) to exchange buy/sell cash for digital cash. Anyone can be a teller. Tellers charge a fee. Teller & user rate each other. When 2 people send money each other via Abra, happens instantly, . No FX volatility.
Awaking the Sleeping Giant: The Natural Resource Industry and the Blockchain
Note: Hispresentation was in English, but I thought it was extremely considerate that he had his slides translated into Chinese as well. Every slide had simultaneous English & Chinese descriptions so that the attendees using the live translation headsets could follow along easier. If I ever present in another country again, I'll try and plan ahead like he did. Was very thoughtful.
Why is BHP interested in the Blockchain? They are the largest mining company in the world (natural resources mining, not Bitcoin mining. Hehe) They are a global distributed organisation. So a distributed Blockchain
Project Rai Stones. Sample tracking of geological samples. They are highly valuable resources. Some of the wells cost $100M, and you only get 1 chance to take the sample. They currently only track the samples manually through emails & spreadsheets. They are working with Consensys & Blockapps. Runs on Ethereum & IPFS, on top of Microsoft Azure. 1 node at BHP, 1 at their collaborator, 1 at their regulator. 3 roles in the business flow, BHP out in the field, the analysis team, and BHP corp. They create/register a smart contract on the network for each sample. When the person collects the sample, they go to the dashboard, click the checkboxes to say they acquired, that updates the smart contract. They ship it off, so they put in the details of which analysis office it is being sent to, updates state from collected to shipped. Analysis team can log in, see what samples are in transit to them to be analysed. They receive it, give it a unique Id based on their internal process. They get trusted tracking of samples, and real time updates.
What if they could automatically operate machines, they could help avoid bad combinations of machines operating at the same time. Like a crane operating on an oil rig, when a helicopter is coming in. Disable a piece of machinery if it is past its allowed usage before routine preventative maintenance. Disabled until it is tested, and certified as okay on the Blockchain. Stop unqualified people from using a tool or vehicle.
Ore gets mined and put onto shipping freighters. Need to track Provenance, custodians, entire supply chain.
Need to give regulatory data to the regulators in each country the operate in. All the mines in the industry need to submit this public data to gov, it all gets aggregated, and disseminated. But it costs HEAPS to do this. What if they built a consortium chain. They can all publish the public data, ready to be analysed instantly by peers. Could make the entire industry more effienct and transparent by making the consortium not just for the 1 country, but a public one. Give a global transparent view of the entire industry. Would help drop costs of compliance.
They started on Ethereum Mainnet & Testnet. Now they are seeing the emergence of many private chains. They will see the bridging between chains. Seen that Ethereum plans on sharding (many chains). Forsees that there will be a global mesh of these Public & Private chains all supporting each other.
Cotricity – “a prosumer to business”- virtual energy market on the Ethereum blockchain (Consensys)
https://co-tricity.com Energy meets Blockchain Joint venture between Consensys & an energy company in Germany. Energy sector is changing rapidly. Prosumer is someone with generative capacity (eg. Solar panels & battery storage). Normal smart meter collects usage about production & consumption. Tracked on Ethereum. Matches up Prosumers to local community things like Schools. The local environmental and economic benefits of keeping it in the local community.
Mechanism design, "reverse game theory". Goal is to effectiveise the energy market and reduce costs. Means creating incentives such that the optimal strategy for every participant results in the realisation of this goal. e.g. Help to smooth out the peak in the morning, give a small reward for not using energy in the morning
