Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet.
If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

Beginners guide to Syscoin (SYS) and why you should be investing in this cryptocurrency in 2018

What is Syscoin?

Some have described Syscoin (SYS) as the Shopify, Amazon and Ebay of the blockchain world. Syscoin is a revolutionary cryptocurrency that offers near zero cost financial transactions, incredible speed and provides businesses the infrastructure to trade goods, assets, digital certificates and data securely. Syscoin isn’t just about money and trading, it has the ability to attract various business types thanks to its native set of features geared towards business on the blockchain. From eBay traders and High Street shops to Medical applications, Insurance and Gaming, Syscoin’s decentralized network benefits everyone!
Syscoin is developed by Blockchain Foundry (BF). BF provides blockchain technology based services, projects and products for a wide variety of use cases with the stated aim of disrupting markets by leveraging the potential of blockchain technology. Syscoin is mainly known to be the first cryptocurrency to offer a fully decentralized marketplace based on blockchain. What is lesser known is that this is only a part of what Syscoin offers.
With the introduction of Masternodes in February or March 2018 SYS will be transformed from just a ’marketplace coin’ to a completely ‘utilitarian coin’. The Masternode infrastructure allows the addition of decentralized databases and file storage, increased transaction speed to surpass POS/Visa/Mastercard capabilities, true Turing complete smart contract capabilities for unlimited business logic, sidechains, application layers and an identity layer. This will all be accessible through an API, rather than a new language, enabling nearly any developer to create any blockchain application they can conceive. This will usher in the next generation of blockchain applications - made for new or existing businesses - by conveniently offering everything available from the blockchain space today.

SYS Origin

The blockchain as conceptualized by Satoshi Nakamoto back in 2008 envisioned a peer-to-peer electronic cash network that would prevent double-spending. A year later, the blockchain became an integral part of bitcoin, serving as the latter's public ledger of transactions. Although Nakamoto's reference client mentioned a decentralized marketplace service, the subsequent implementation did not incorporate this due to a lack of resources.
Syscoin was initially described in a 2014 draft whitepaper that envisioned Decentralized Marketplace Creation, Decentralized Smart Contracts and Documents, Decentralized Certificate Issuance and Transfer, and Decentralized Data Storage and Retrieval, as among the services that it would offer upon its release.
Syscoin aimed to bring Nakamoto's vision of a decentralized marketplace back into the blockchain, among the other commercial-grade services it aims to deliver to clients. Other services that Syscoin plans to provide include secure data storage and transfer, and unique user aliases that link their owners to the services controlled by the alias.
The early Syscoin wallet was superseded by the release of Blockmarket Desktop 1.0 on September 12, 2017, marking the culmination of Syscoin's vision of a fully decentralized marketplace with a desktop GUI based on the blockchain.
The planned release of Blockmarket Web, a fully web-based version, and Blockmarket Professional in 2018 takes that vision one step further, as more advanced seller stores become a reality.

The Team

The Team that NEVER quits! Before the launch of Syscoin (Q3 2014), there was a presale ICO by Moolah (as a partner), which turned out to be detrimental for Syscoin. The project raised around 1,000BTC for development but the Syscoin Team only managed to access 250BTC which were used for price support. Moolah (Ryan Kennedy) absconded with the bulk of the ICO funds and the Syscoin team were left with ~30million Syscoin at a price around 400 satoshi. Even after this tragic event, the devs didn’t quit and continued to work on the project without stopping. The case against Moolah is still on-going. See the article from CoinDesk here: http://www.coindesk.com/uk-court-syscoin-injunction-moolah-750-btc/.
What is this detail telling us about the dev team? While some crypto projects are just scams and bring little to no innovation, they’ve proven that they are in it for the long term - ably demonstrated by the fact that they continued to work despite their funds being stolen. And now that hard work is beginning to pay off with the entire team going full-time for the first time in January 2018 and new developers being hired following VC funding for BF.

What is Blockmarket Desktop?

Building on the World's First Decentralized Marketplace, Blockmarket is the newest generation of Syscoin's Desktop wallet with a complete, state-of-the-art marketplace built-in where you can securely and reliably buy and sell any items you wish. Entire stores can be created directly through the marketplace where you can sell your own products or re-sell others’ products for commission. Use of blockchain technology eliminates middlemen, credit card fees, maintenance fees, downtime and political interference. Persons are literally able to buy or sell anything to anyone, anytime, anywhere on Earth! Blockmarket Desktop was launched on September 12, 2017.

Key Blockmarket Features

• Price Pegging to currencies such as USD, EUR, GBP, CAD, CNY and BTC
• Bitcoin and Zcash as payment options
• Arbitrated Escrow
• Encrypted Messaging
• KYC/AML Compliance
• Images
• Unlimited Inventory Items

Name Aliases

Wallet addresses for cryptocurrencies generally consist of a unique string of between 27-34 alphanumeric characters. Such an address isn’t easy to memorize. Although the addresses can be added to an address book within the wallet, Syscoin has taken the user's convenience one step further, allowing you to create a unique Alias for your wallet address, such as a name, title, or characters specific to a username. These can be used to send SYS from home, to a mobile wallet, to work, to friends, to common suppliers or to repeat customers easily, without requiring any memorizing, writing it down, copy & pasting or emailing yourself the address.

Digital Certificates

Using the cryptography of the blockchain persons can issue, authorize, and exchange digital certificates of any kind. With Syscoin anyone can issue provably-unique certificates with text or ASCII content to one or multiple parties on the Syscoin blockchain. These certificates can be authenticated by anyone via Syscoin’s cryptographic proof of work. This allows for the creation and free exchange of any kind of digital asset such as ownership certificates, warranties, receipts, tickets, certifications, diplomas, software licenses and more.

Integrated Exchanges

Integrated Crypto exchanges - Flypme and Changelly will facilitate exchanging 30+ cryptos for SYS, directly within the Blockmarket wallet.

Security Audit Verified

Blockmarket was successfully and independently security audited by Digital Boundary Group and was deemed low risk. Audit Results: [https://medium.com/@BlockchainFoundry/blockmarket-security-audit-results-and-next-steps-f69f94f149bf]

Blockmarket Web – (The Key to Mass Adoption)

BM web will bring SYS’s existing decentralized marketplace and all its features into a web-based version, enabling ease of use with a simple email and password login (grandma friendly) without any need for downloading a wallet or waiting for sync. Blockmarket web will be launched in February 2018.

Key Syscoin Developments

Masternodes

Ability for world-class transactions-per-second performance to scale-out with added nodes (theoretically 100k TPS per 1000 Masternodes, 300k TPS/3k masternodes, etc). In later releases, masternodes will also process smart contracts and facilitate sharded+encrypted offchain file-storage (with onchain anchors), among other touted functionality. They should also result in steadying the price movements - less volatility as holding will be incentivized

Smart Contracts

Scalable Ethereum Virtual Machine: Allows Turing complete smart contracts to be executed following the ethereum protocol at a much faster speed and at a fraction of the ethereum gas price.

Assets & Token Issuance

With its token issuance service, Syscoin allows anyone to create a custom asset token which can then be sent directly to anyone else on the network. This facilitates a variety of use cases including ICO token issuance, supply chain management, reward points, and loyalty programs.

Anonymous Transactions

Anonymous transactions: via mixing/shuffling at user-specified denomination. Afterwards, additional tech will be added in the near future which will further compound the degree of anonymity provided -Add ValueShuffle running on top of the masternode layer and you have the world's most advanced privacy tech in any coin. This brings true money fungibility to Syscoin and the missing link for true economic sovereignty. https://twitter.com/realSidhuJag/status/948588279540035584

Instant Send

Transactions can be sent and received instantly. This represents a similar sending capability as Dash, but is a step beyond- A type of backend node locking will allow an instantly received sum to be sent immediately, without delay, and without network risk of double-spend.

Discord Log from Ravencoin Open Developer Meeting - Oct 5, 2018

joey at 1:57 PM

What kind of transaction types are possible with RVN assets? Is it possible to create an asset that has a set lifetime or self-destruct time?

Tron at 2:00 PM

Not for assets/sub-assets/unique. We might be able to do that with voting tokens.

RavencoinDev at 2:01 PM

Hello Everybody!📷1

Hi boss📷1

[Dev] Blondfrogs at 2:01 PM

BruceFenton at 2:01 PM

Probably lots of ways to do a self destruct on second layer as well if desired

russ at 2:01 PM

suuuuuupso what is todays topic?

RavencoinDev at 2:02 PM

Thanks for joining us today. We would like to discuss the current status of the 2.1 release.As well as doing an open Q&A at the end.First though I want to thank everybody that helped get the word out on upgrading to the 2.0.4.1 release!Without that fix being in place and exchanges and pools upgrading we would be having a different conversation today.This community is amazing.

russ at 2:04 PM

we would have ended up like pigeoncoinnot a good look📷2

watsure at 2:05 PM

Hello Mr. God

RavencoinDev at 2:05 PM

Exactly

russ at 2:05 PM

i gave pigeoncoin the pullrequest but they ignored meglad we have competent devs

[Dev] Blondfrogs at 2:05 PM

Everyone, So we are planning on getting out build 2.1 as soon as possible. We are still doing bug fixes, and getting the code hardened for release. There is currently one bug is the asset layer that we are fixing right now, and once that is done we should have a couple days of testing. It would be lovely if the community helped with testing, and we appreciate all of the testing that the community has already done. Once, we have a basic build that is tested, we are going to make a public release and notify the miners and pools.

RavencoinDev at 2:06 PM

Once that bug is addressed a release branch will be created.

russ at 2:06 PM

that duplicate ownership asset bug is nasty

RavencoinDev at 2:06 PM

You should all be able to build that and jump on testnet.

[Dev] Blondfrogs at 2:07 PM

@russ Yeah, didn't see that one. BUt I have a fix right now that seems to be working on my local machine

RavencoinDev at 2:07 PM

We need as much testing help from our devs as possible.

[Dev] Blondfrogs at 2:07 PM

so, I will have that pushed up with the day.

russ at 2:07 PM

nice

[Dev] Blondfrogs at 2:08 PM

Just a reminder, that when the new wallet is published, if you don't update your wallet by the time assets are voting in by the blocks you will fork. So, we are going to try and get the wallet out there as soon as we can so users have weeks to upgrade.

Skan at 2:09 PM

Hey everyone

RavencoinDev at 2:10 PM

Any questions comments about the 2.1 release?

Skan at 2:10 PM

Mojave support?

SpyderDev at 2:10 PM

Yes and no

RavencoinDev at 2:10 PM

Good question SkanRight now that's also an issue with Bitcoin.

SpyderDev at 2:12 PM

The short version for Mojave is that the released binaries will work fine.

Skan at 2:12 PM

Interesting, so is it likely going to be a future upgrade that brings stability?

SpyderDev at 2:12 PM

However, developers should hold off.

RavencoinDev at 2:12 PM

We are currently building on High Sierra

Skan at 2:12 PM

Ok good to know for those who ask

SpyderDev at 2:13 PM

There is an incompatibility with Berkeley db version 4 that causes a segfault on init.

RavencoinDev at 2:13 PM

Or using the build scripts that Under created to build on Linux. Thjanks @Under

[Master] Roshii at 2:13 PM

Looks I'm late to the event

[Dev] Blondfrogs at 2:13 PM

THE MASTER!

RavencoinDev at 2:13 PM

Sorry it's late for you @[Master] Roshii

Skan at 2:14 PM

master roshi is never late, he is simply the turtle hermit

SpyderDev at 2:14 PM

One can upgrade Berkeley-db to the latest version and compile with the --incompatible-bdb and things will run, but there are some unknowns as far as wallet compatibility is concerned.

RavencoinDev at 2:15 PM

Raven will likely follow Bitcoin on Mojave support.

SpyderDev at 2:15 PM

The release binaries are compiled on Linux which we have tested on Mojave, so as long as you aren't compiling binaries go ahead and update to Mojave

RavencoinDev at 2:15 PM

It's a problem they have to solve as well, so...

SpyderDev at 2:15 PM

There is supposed to be a patch to bdb, but so far it isn't working

[Master] Roshii at 2:15 PM

@RavencoinDev it's never late for me.

Skan at 2:15 PM

Ok, and for the devs interested just point them to the berkeley upgrade with some warnings or to Under's scripts?

RavencoinDev at 2:16 PM

Right, the wallet runs just fine on Mojave. It's just a developer issue.

[Master] Roshii at 2:16 PM

If I can say anything it will be : don't update to Mojave

SpyderDev at 2:16 PM

There is a warning note in the docs section for OSX building

RavencoinDev at 2:16 PM

Mojave slowed down @[Master] Roshii and the iOS wallet.

Skan at 2:16 PM

YikesOk good to know, just want to be able to help / point people in the right direction

RavencoinDev at 2:17 PM

Thanks @Skan

SpyderDev at 2:17 PM

There is also an issue with Mojave dark mode and the QT wallet that makes things difficult to read (white on white text). We have a workaround which is to disable dark mode for QT in the plist file.

Skan at 2:17 PM

Ok so this is going to be pretty soon then, right ? Next week, likely?

RavencoinDev at 2:18 PM

Any further Mojave questions?Which @Skan ?

Skan at 2:18 PM

I think that covers it for me2.1 releaseIn order to have weeks to upgrade before main net

RavencoinDev at 2:18 PM

Yes, it is looking like we can work through this last issue with asset re-org very soon.Likely early next week.

Skan at 2:20 PM

Is 2.1 going to have any UI updates ?

RavencoinDev at 2:20 PM

Yes, frogs has more details.

[Dev] Blondfrogs at 2:20 PM

The UI is done. It is currently in the develop2. So if you have built the develop2 branch, you would be looking at the new UI for now.

RavencoinDev at 2:21 PM

There have been other QT designs kicked around and we would love to see more from the community.

[Dev] Blondfrogs at 2:21 PM

Future upgrades to come though. but those won't be mandatory upgrades. Just visual upgrades.

SpyderDev at 2:21 PM

The UI tweaks are subtle, but they make a big difference.

Skan at 2:22 PM

Very cool, I will check out dev2 branch

russ at 2:22 PM

new asset creation UI is awesome

Skan at 2:22 PM

I saw that, I like it. And the longer asset holdings list

RavencoinDev at 2:22 PM

@russ Don't make @[Dev] Blondfrogs head any larger...

russ at 2:23 PM

lol

RavencoinDev at 2:23 PM

Other 2.1 release questions/comments?

Skan at 2:23 PM

Cant think of anything else at the momentThanks!

Hans_Schmidt at 2:23 PM

Is dividend support officially part of 2.1 release? It wasn't intuitive to me how that works.

RavencoinDev at 2:24 PM

No it will be in the next release. However, you could write a script that would provide the same functionality with what will be released in 2.1.

Skan at 2:25 PM

I heard something about Phase 4 being complete already, is that true, and is that in 2.1?

RavencoinDev at 2:25 PM

List all addresses with an asset, loop through sending X raven to each.

Skan at 2:25 PM

Unique assets>

RavencoinDev at 2:25 PM

Yes, Unique assets are complete.(edited)

Tron at 2:25 PM

Dividend support can be done without modifying the protocol. We can add it to a version of the software that can be used by the payer, without requiring others to upgrade.So we did phase 1, 2, 4

Skan at 2:26 PM

Oh wowGreat job everyone!

RavencoinDev at 2:26 PM

Yeah, we're super excited about the use cases that assets and unique assets provide to our develoepers(edited)

Skan at 2:27 PM

Can you tell us anything else about this separate software client? Will it be geared more towards enterprise use in general or will it just be that feature?

RavencoinDev at 2:27 PM

Speaking of, do any of you have a dev project in the works with assets?

russ at 2:27 PM

well its not a separate software client, its a backwards compatible release @Skan(edited)kind of like a softfork if you know what that is

Skan at 2:28 PM

Yeah unique assets will be awesome, actually there's a korean community member planning on issuing them along with silver ravencoinsIf im not mistaken

RavencoinDev at 2:28 PM

That's awesome!

russ at 2:28 PM

@RavencoinDev @Scotty is working on an asset explorerhttp://ravencoin.asset-explorer.net/

RavencoinDev at 2:29 PM

Yes, we've been watching that.

Skan at 2:29 PM

I am working with him on a Korean translation of the whitepaper, x16r whitepaper, and an introduction article so that we can take advantage of our availability in that market📷1

RavencoinDev at 2:29 PM

Super excited to see that mature.

Skan at 2:29 PM

@russ ah ok that makes senseWill there be anything else to that release?

RavencoinDev at 2:30 PM

Thanks @Skan. We want Raven to span the globe.Okay, Open Q&A time.What other questions do you guys have?

Skan at 2:31 PM

This release with rewards capability, will there be anything else added/changed for that version?

Tron at 2:31 PM

It might be released as phase 3, 5, 6.Although it could be released separately, without impacting anything.

Skan at 2:32 PM

Ah ok, so all of these features can be opted-into by someone who wants to take advantage, without cluttering the experience for a basic user

Tron at 2:32 PM

Phase 5 and 6 will be together as it requires a hard-fork.

RavencoinDev at 2:33 PM

Yes, we want to focus on user experience so it's super simple to do what you want to do.

Skan at 2:33 PM

Awesome

russ at 2:33 PM

so is anyone working on RSK yet

[Dev] Blondfrogs at 2:34 PM

We aren't yet.

russ at 2:34 PM

yea im gonna have a look at the code soon

[Master] Roshii at 2:34 PM

Who said ravencoin needs RSK

RavencoinDev at 2:34 PM

It'd be great to have that done by the community.

russ at 2:34 PM

i think some people would like smart contracts @[Master] Roshii

Skan at 2:35 PM

RSK would be great for token distributions

russ at 2:35 PM

the real trick would be getting RSK to recognize assets

Tron at 2:35 PM

RSK, Segwit, Lightning are all on the table, but lower priority than phases 3, 5, 6.

[Master] Roshii at 2:35 PM

This is just like saying let's do what ravencoin does in the old fassion!

russ at 2:35 PM

well not really, smart contracts can do other things

[Master] Roshii at 2:36 PM

What's the RBF status @Tron

Skan at 2:36 PM

Keep us posted russ I think that would be amazingWhen you write smart contracts in RSK what language is it in?

russ at 2:36 PM

solidity i thinlthink

RavencoinDev at 2:36 PM

yes

russ at 2:36 PM

eth contracts also work on RSKso thats a plus

Skan at 2:37 PM

Ok great so we dont even have to work on templates or anything

RavencoinDev at 2:37 PM

Having solidity contracts that interact with Raven assets would open up a lot of possibilities.

Skan at 2:37 PM

I think so too, especially for stuff like tokens in gaming use case📷1

russ at 2:37 PM

i guess it would also help with cross chain atomic swaps too

Skan at 2:37 PM

Yep

RavencoinDev at 2:37 PM

Yes!

russ at 2:38 PM

BTC directly for an asset

Skan at 2:38 PM

sounds like a good product

russ at 2:38 PM

making ICOs easier

Tron at 2:38 PM

Yes, cross-chain atomic swaps would be amazing with user issued assets.

RavencoinDev at 2:39 PM

Other questions?

Skan at 2:40 PM

Smart contract atomic swap erc20token 1:1 for their new RVN counterpart

Hans_Schmidt at 2:40 PM

I believe that every cross-chain atomic swap implementation I have seen requires a trusted federation. That's even true for RSK.

Tron at 2:40 PM

@Skan I like it!

Skan at 2:42 PM

No more questions from me

RavencoinDev at 2:42 PM

Okay, seems that we're winding down on the Q&A.Thank you all for joining us today. I've really liked how this discussion has worked out on Discord.Did anybody miss IRC today?

russ at 2:43 PM

hell no

Hans_Schmidt at 2:43 PM

Like a toothache

russ at 2:43 PM

this was waaay better

RavencoinDev at 2:44 PM

📷

Hans_Schmidtat 2:44 PM

Missed the mems tho

RavencoinDevToday at 2:44 PM

I agree. I was even able to fix my typos.That's right, we had some epic memes last time.Where are you @Pathfinder

Chatturga at 2:45 PM

@Pathfinder Do you have an epic meme for us today?

Skan at 2:45 PM

Meme please

[Master] Roshii at 2:46 PM

Can somebody give @Pathfinder a Master Memer role and color

Useful Beginner's Guide to Syscoin

What is Syscoin?

Some have described Syscoin (SYS) as the Shopify, Amazon and Ebay of the blockchain world. Syscoin is a revolutionary cryptocurrency that offers near zero cost financial transactions, incredible speed and provides businesses the infrastructure to trade goods, assets, digital certificates and data securely. Syscoin isn’t just about money and trading, it has the ability to attract various business types thanks to its native set of features geared towards business on the blockchain. From eBay traders and High Street shops to Medical applications, Insurance and Gaming, Syscoin’s decentralized network benefits everyone!   Syscoin is developed by Blockchain Foundry (BF). BF provides blockchain technology based services, projects and products for a wide variety of use cases with the stated aim of disrupting markets by leveraging the potential of blockchain technology. Syscoin is mainly known to be the first cryptocurrency to offer a fully decentralized marketplace based on blockchain. What is lesser known is that this is only a part of what Syscoin offers.   With the introduction of Masternodes in February or March 2018 SYS will be transformed from just a ’marketplace coin’ to a completely ‘utilitarian coin’. The Masternode infrastructure allows the addition of decentralized databases and file storage, increased transaction speed to surpass POS/Visa/Mastercard capabilities, true Turing complete smart contract capabilities for unlimited business logic, sidechains, application layers and an identity layer. This will all be accessible through an API, rather than a new language, enabling nearly any developer to create any blockchain application they can conceive. This will usher in the next generation of blockchain applications - made for new or existing businesses - by conveniently offering everything available from the blockchain space today. In simple terms think Dash + Ethereum/Lisk + Monero + Nano + Storj + Particl capabilities all in one coin!    

SYS Origin

The blockchain as conceptualized by Satoshi Nakamoto back in 2008 envisioned a peer-to-peer electronic cash network that would prevent double-spending. A year later, the blockchain became an integral part of bitcoin, serving as the latter's public ledger of transactions. Although Nakamoto's reference client mentioned a decentralized marketplace service, the subsequent implementation did not incorporate this due to a lack of resources.   Syscoin was initially described in a 2014 draft whitepaper that envisioned Decentralized Marketplace Creation, Decentralized Smart Contracts and Documents, Decentralized Certificate Issuance and Transfer, and Decentralized Data Storage and Retrieval, as among the services that it would offer upon its release.   Syscoin aimed to bring Nakamoto's vision of a decentralized marketplace back into the blockchain, among the other commercial-grade services it aims to deliver to clients. Other services that Syscoin plans to provide include secure data storage and transfer, and unique user aliases that link their owners to the services controlled by the alias.   The early Syscoin wallet was superseded by the release of Blockmarket Desktop 1.0 on September 12, 2017, marking the culmination of Syscoin's vision of a fully decentralized marketplace with a desktop GUI based on the blockchain.   The planned release of Blockmarket Web, a fully web-based version, and Blockmarket Professional in 2018 takes that vision one step further, as more advanced seller stores become a reality.    

The Team

The Team that NEVER quits! Before the launch of Syscoin (Q3 2014), there was a presale ICO by Moolah (as a partner), which turned out to be detrimental for Syscoin. The project raised around 1,000BTC for development but the Syscoin Team only managed to access 250BTC which were used for price support. Moolah (Ryan Kennedy) absconded with the bulk of the ICO funds and the Syscoin team were left with ~30million Syscoin at a price around 400 satoshi. Even after this tragic event, the devs didn’t quit and continued to work on the project without stopping. The case against Moolah is still on-going. See the article from CoinDesk here: http://www.coindesk.com/uk-court-syscoin-injunction-moolah-750-btc/.   What is this detail telling us about the dev team? While some crypto projects are just scams and bring little to no innovation, they’ve proven that they are in it for the long term - ably demonstrated by the fact that they continued to work despite their funds being stolen. And now that hard work is beginning to pay off with the entire team going full-time for the first time in January 2018 and new developers being hired following VC funding for BF.

What is Blockmarket Desktop?

Building on the World's First Decentralized Marketplace, Blockmarket is the newest generation of Syscoin's Desktop wallet with a complete, state-of-the-art marketplace built-in where you can securely and reliably buy and sell any items you wish. Entire stores can be created directly through the marketplace where you can sell your own products or re-sell others’ products for commission. Use of blockchain technology eliminates middlemen, credit card fees, maintenance fees, downtime and political interference. Persons are literally able to buy or sell anything to anyone, anytime, anywhere on Earth! Blockmarket Desktop was launched on September 12, 2017. Download Blockmarket Desktop 1.2    

Key Blockmarket Features

- Decentralized Marketplace

The marketplace platform provides a decentralized and high redundant channel for selling goods and services. Features include: • Price Pegging to currencies such as USD, EUR, GBP, CAD, CNY and BTC • Bitcoin and Zcash as payment options • Arbitrated Escrow • Encrypted Messaging • KYC/AML Compliance • Images • Unlimited Inventory Items  

- Name Aliases

Wallet addresses for cryptocurrencies generally consist of a unique string of between 27-34 alphanumeric characters. Such an address isn’t easy to memorize. Although the addresses can be added to an address book within the wallet, Syscoin has taken the user's convenience one step further, allowing you to create a unique Alias for your wallet address, such as a name, title, or characters specific to a username. These can be used to send SYS from home, to a mobile wallet, to work, to friends, to common suppliers or to repeat customers easily, without requiring any memorizing, writing it down, copy & pasting or emailing yourself the address.  

- Digital Certificates

Using the cryptography of the blockchain persons can issue, authorize, and exchange digital certificates of any kind. With Syscoin anyone can issue provably-unique certificates with text or ASCII content to one or multiple parties on the Syscoin blockchain. These certificates can be authenticated by anyone via Syscoin’s cryptographic proof of work. This allows for the creation and free exchange of any kind of digital asset such as ownership certificates, warranties, receipts, tickets, certifications, diplomas, software licenses and more.  

- Integrated Exchanges

Integrated Crypto exchanges - Flypme and Changelly will facilitate exchanging 30+ cryptos for SYS, directly within the Blockmarket wallet.  

- Security Audit Verified

Blockmarket was successfully and independently security audited by Digital Boundary Group and was deemed low risk. View Audit Results.

BM Desktop – Quickstart Tutorials    

Blockmarket Web – (The Key to Mass Adoption)

BM web will bring SYS’s existing decentralized marketplace and all its features into a web-based version, enabling ease of use with a simple email and password login (grandma friendly) without any need for downloading a wallet or waiting for sync. Blockmarket web will be launched in Q1 2018.   This launch will be accompanied by a marketing campaign roll-out that seeks to build brand recognition with audiences within the existing crypto ecosystem and more significantly with the broader, global, non-crypto audience. For this reason Ballistic Arts, a full-service marketing agency was retained by BF. BF Engages Marketing Agency    

Primary Target Market + Value Potential

The primary target market for BF’s Syscoin/Blockmarket web flagship is the retail e-commerce industry. This sets up their decentralized marketplace to rival such commercial giants as Amazon ($648B market cap), Alibaba ($453B market cap) and eBay ($43B market cap). According to eMarketer’s Worldwide Retail and Ecommerce Sales report, global retail e-commerce sales for 2017 were $2.3 Trillion. This is expected to reach an estimated $4 Trillion by 2020 reflecting the rapid growth within this sector.   To perform a very simple assessment of the Syscoin/Blockmarket web’s potential let’s assume that a 1% portion of the forecasted $4 trillion market is captured, which represents $40 billion in revenue. Assuming a sales to market cap ratio of 1:1 for simplicity, the circulating supply of 531 million SYS, with a $40 billion market cap yields a price of roughly $75 per coin. However, with masternodes that limit the circulating supply and token utility that extends beyond retail e-commerce, the SYS price could likely reach much higher. Please note that these are just very simple assumptions and projections for this exercise, however the real world driven potential that this project has is clearly evident.    

Key Syscoin Developments

- Z-DAG: Zero Confirmation Transactions with Double Spend Protection (WORLD’S FIRST)

View Developer’s Twitter post View Syscoin’s Twitter post  

- Masternodes

Ability for world-class transactions-per-second performance to scale-out with added nodes (theoretically 100k TPS per 1000 Masternodes, 300k TPS/3k masternodes, etc). In later releases, masternodes will also process smart contracts and facilitate sharded+encrypted offchain file-storage (with onchain anchors), among other touted functionality. They should also result in steadying the price movements - less volatility as holding will be incentivized.  

- Masternode Rewards + Min. Hardware Specs

Masternode Rewards + Min. Hardware Specs Masternode ROI Calculator  

- Smart Contracts

Scalable Ethereum Virtual Machine: Allows Turin complete smart contracts to be executed following the ethereum protocol at a much faster speed and at a fraction of the ethereum gas price.  

- Assets & Token Issuance

With its token issuance service, Syscoin allows anyone to create a custom asset token which can then be sent directly to anyone else on the network. This facilitates a variety of use cases including ICO token issuance, supply chain management, reward points, and loyalty programs.  

- Anonymous Transactions

Anonymous transactions: via mixing/shuffling at user-specified denomination. Afterwards, additional tech will be added in the near future which will further compound the degree of anonymity provided -Add ValueShuffle running on top of the masternode layer and you have the world's most advanced privacy tech in any coin. This brings true money fungibility to Syscoin and the missing link for true economic sovereignty. View Developer’s Twitter post.  

- Instant Send

Transactions can be sent and received instantly. This represents a similar sending capability as Dash, but is a step beyond- A type of backend node locking will allow an instantly received sum to be sent immediately, without delay, and without network risk of double-spend.

Run a 0.14 Full-Node on RaspberryPi3 Pruned(less than 16GB SD needed)

Hi!
Happy if this guide helps you.
Tip if you want: 19656Uwdwko5RjtnuwQENpjBwE3ChzD59v
UPDATE 04/06/17
Add 'uacomment=UASF-SegWit-BIP148' into your bitcoin.conf if you want to signal UASF.
UPDATE 03/13/17
ADDED a tl;dr; Version at the end of this Post.
UPDATE 03/12/17:
Just to test it - I reinstalled all on 8GB SD and it works as well. But maybe you should use at least 16GB for the beginning.
Using a 128GB card for the first version was a little bit stupid - so I reinstalled everything on a 8GB SD card. Including Linux and a pruned blockchain - and it works.
I used prune=550 and Jessie Lite (headless / command line) - without wallet and gui.
The SD is almost full, but it works so far
I also updated the whole manual a bit to make things more clear. Thank you for all your feedback!
Just started my Bitcoin Node today and wanted to share the way I did it with people who are interested in running their own full node. It took some time to write everything down - hopefully correct so far.
I am sure, many people around bitcoin are way more informed and educated as I am - I am the noob. So I wrote this manual to help users like me - noobs, to get started with a cheap, simple bitcoin node on raspberry pi.
Have fun!
I wanted to get my Raspberry Pi 3 working as a node to support the network. Actually the process of installing and running the node was more or less easy - but for Noobs (like I am) it might be a bit tricky to start the whole thing, because there are different ways.
Did you - like me - think you would need +120GB on the raspi, external USB HDD to be a full node? You won't!
If you have a Raspberry and you know what Bitcoin is, I guess, you are a little bit aware of linux, networks and of course bitcoin - so I won't go into detail too much.
This guide is just a little helper to get a full node running on your raspberry pi. Thanks to the help of the nice people in this sub and of course the documentation by the developers, I got it working - and of course also special thanks to raspnode.com - as I followed their tutorial to start - I went some other ways here and there - so please read carefully.
For the Part 2 I would suggest to have http://raspnode.com/diyBitcoin.html open and read through my manual.
I split the tutorial in 2 Parts - PART ONE is about installing the client on your PC and downloading the Blockchain.
PART TWO is about the setup of the raspberryPi and transferring the pruned blockchain to the pi and run it as a full node!
The first thing to be aware of is: You actually need to download the whole blockchain to get this working - if you already have your bitcoin client synced on the PC / MAC great you can reuse it!
Now you might think "but you said less than 16GB in the title!"
Yes, but the good thing is you won't need to download it on your Raspberry, neither you need to sync it completely on your raspberry which took ages (weeks!) before. When you finished this Guide, you will just have a max. 4GB Blockchain on your Raspberry Pi - but it still is a full node! The magic word is Pruning.
Maybe even a 8GB SD Card works just fine including Linux (jessie lite)!
So, if you already have a full node on your PC - Great you can almost skip PART ONE - BUT have at how to Prune in PART ONE if you don't know about it.
For PART TWO you'll need a Raspberry Pi 2 or 3 (I used 3) min. 8GB (works also) or better 16GB SD Card. (I used a 128GB for the first version of this manual - which is way too big)

PART ONE

This is the manual how to get started on you PC / MAC / Linux (I did it on Win7)
Go to: https://bitcoin.org/en/download and download the core Client for your Machine (I used win64).
Install it and configure it to save the Blockchaindata to the directory of your choice - so instead getting 120GB on your C drive, I would suggest to download it to another place like a USB drive.
You can set this up during the install. Standard folder for the blockchain folder is "%APPDATA%\Bitcoin" on Windows.
or you can do it after the install by creating a bitcoin.conf file inside your installation folder / or %APPDATA%\Bitcoin and add
datadir=l:\yourfolder
to the file. Line by line.
By the way here you could also just add dbcache - to use more memory to speed up the process a bit:
dbcache=4096
if you don't want to use the settings inside the program. (you can also set this inside the program under settings! If you have this inside the bitcoin.conf you will see the amount you set there from inside the program - it overrides the values)
You can check inside the windows client under settings, if you can see a manual dbcache is set by having a look at the left footer area. When your dbcache value shows up, everything is fine.
So the Blockchain download process will take time - maybe a few days! Depending on your machine, internet connection and HDD.
The Blockchain is huge as it contains every single transaction of the past until today. You won't need to keep your PC running all the time, you can turn it off and on and it will resync automatically when you start bitcoin-qt.exe!
Make sure to close the client always via "quit" - ctrl+q.
After you have your bitcoin core installed, the blockchain downloaded and synced - you are ready to PRUNE!
First - close the Client and let it close smoothly. After it is really closed you can follow these steps:
By pruning, your blockchain will dramatically shrink. From 120GB to just a few GB.
Be aware, that you will lose your Downloaded Blockchain as pruning will erase a big chunk of it! If you have enough space, you could of course keep the full blockchain saved somewhere on another HDD.
You can prune by editing your bitcoin.conf file by adding:
prune=550
I used prune=1024 - not sure where the differences are right now (min. prune=550). (for my 8GB version I used 550! I suggest to use this.)
Save the bitcoind.conf file and restart your windows client.
It will now clean up the Blockchain. So just the latest blocks are saved. The client should start without any problems. Maybe it takes some time to prune the blockchain data.
Check if everything works normally (the client opens as usual, you can see an empty wallet) than close the client.
Inside the Bitcoin Folder, you'll find two folders called:
blocks chainstate
those are the interesting folders containing the important data (now pruned) - and we will transfer those two to the raspberry later!
Now you are good to start the raspi transfer explained in the next part.

PART 2

Here is what I did:
1) I installed Raspian Pixel (https://www.raspberrypi.org/downloads/raspbian/) using a 128 GB SD - which is not needed because of "Pruning" - I think a 16GB card might work, too! (You can also install Raspian Jessie Lite - which saves you even more space, as it runs headless - only command line) (Updated: It is better to use Jessie Lite to save a lot of space - when you are fine with only command line)
2) I followed partly this tutorial to get everything running and setup:
http://raspnode.com/diyBitcoin.html
Please have a look at it - I have copied the Headlines in capitals to let you know what I did, and what I skipped.
On Tutorial Page: Start with RASPBIAN (OPTIONAL) CONFIG OPTIONS.
Set You RasPi up including "EDITING FILES" to save your Layout at the tutorial page and come back here.
I skipped the CONFIGURE USB AND SET AUTOMOUNT process, as we are going to use PRUNING to reduce the 120GB to a tiny filesize - so USB Devices are not needed here!
It was necessary to ENLARGE SWAP FILE to install bitcoin core - otherwise it didn't went through which ended in a frozen raspi.
So have a close look by following the raspnode tutorial at: ENLARGE SWAP FILE.
I have my raspi running via cable to router - but you can also WiFi setup everything described under NETWORKING ON THE RASPBERRY PI.
Now comes the interesting part: Follow the steps at DOWNLOADING BITCOIN CORE DEPENDENCIES - they work fine for 0.14.0 too. Git should be on Board already when you installed Pixel - otherwise you would need to install it.
sudo apt-get install git -y (only jessy lite)
I skipped the next command lines - as I don't use bitcoin-qt wallet. If you want to use it as wallet - do the step.
mkdir ~/bin cd ~bin
Now you are in the folder you want your bitcoin core data be downloaded to via git. I didn't Downloaded the Berkeley Database source code - so I also skipped the whole next command lines

and went on with "INSTALLING BITCOIN"!
I followed the first part but instead downloading 0.13 I took of course the latest version:0.14
git clone -b 0.14 https://github.com/bitcoin/bitcoin.git cd bitcoin ./autogen.sh
this might take some time to start.
If you have trouble with hanging RESOLVING DELTAS - just restart the Raspberry Pi and remove the bitcoin folder inside /~bin using
rm -rf bitcoin
this command will delete the folder and you can reuse
git clone -b 0.14 https://github.com/bitcoin/bitcoin.git

For some reason RESOLVING DELTAS is a common problem with different downloads - so just retry it and at least after 3 times it should work!

as I didn't use the GUI/ Wallet, I ran
./configure --enable-upnp-default --disable-wallet
as I don't need the wallet functionality.
I didn't need to use "MAKE" which saves you maybe up to 2.5 hours.
instead you can just go ahead with:
sudo make install
(If I am wrong in doing so - please let me know)
The install takes some time - and just a heads up: when it gets stuck somewhere - just redo the installation process - it took three times to went through - stuck at some processing.
After the installation took place you can finally get your Raspberry Pi Node running in no time!
To test if the the installation went through - you can just start bitcoind using:
bitcoind &
than check if everything is working so far:
bitcoin-cli getinfo
after a few seconds you should see version: etc...
if not, something went wrong. Try to redo the steps in the raspnode tutorial.
(don't give up if it failed - retry! Ask your questions here)
IMPORTANT: you need to stop bitcoin on your raspberry now!
bitcoin-cli stop
If you don't need an external USB Drive - what I hope - as we are going to use pruning just go ahead and skip the USB part and create a file inside (or follow the raspnode tutorial on how to setup the USB drive):
cd .bitcoin
sudo nano bitcoin.conf
and enter the exact same pruning size you have used on your Desktop Machine to prune. I used 1024 but the minimum is 550. (used 550 for the 8GB SD card on PC and Raspberry)
prune=550
That's it for the raspi.
update: To signal UASF enter in a new line:
uacomment=UASF-SegWit-BIP148

TRANSFER

Now you have to transfer the two folders CHAINSTATE and BLOCKS from your PC bitcoind directory to your raspberry.
I am using a program called "WINSCP" - it is free and easy to use: https://winscp.net/eng/download.php
We need this to transfer the files to the Raspberry pi. Pretty sure you can also do it via SSH - but I am the noob. So let's keep it simple.
Open Winscp and put in the IP Address of your Raspberry Pi, User and Password (same as in SSH)
You should now see the directories on your Raspberry Pi. There is a folder called
.bitcoin
enter it and you will see the two folders
blocks & chainstate
you can delete them on the raspberry as they have some data from your previous test inside.
Make sure you can also see the bitcoin.conf file in that directory, which needs to contain the exact same prune line, like the one on your desktop machine. If not, make sure to edit it via SSH. The line "datadir=l:\yourfolder" is obviously not needed in the Raspberry bitcoin.conf file.
Now grab the two folders CHAINSTATE and BLOCKS from your PC and copy them to your .bitcoind folder.
I also copied banlist.dat, fee_estimation.dat, mempool.dat and peers.dat to the folder - not really knowing if needed! Not needed.
The whole copy process might take some minutes (against some weeks in the old way).
After copying is finished, you can now start bitcoind on the Raspberry.
bitcoind &
the & symbol let you still use the command line while the process is running btw.
The process - if succesfull - will take some time to finish.
bitcoin-cli getinfo
Will give you some informations what is going on right now. When you can see, that it is checking the blocks, this is good!
If you get an error - double check - if you have the correct prune size (same as on desktop machine) - in bitcoin.conf and that this file is inside .bitcoin on RaspberryPi. It took me some time, to find my mistakes.
Congrats! You are almost a part of the network!
To make your node now a fullnode, you will need to go to your router (often 192.168.1.1) and enable portforwarding for your raspberry pi - and open ports 8333 - that's it!
You can now go to: https://bitnodes.21.co/nodes/
scroll down to "JOIN THE NETWORK" and check check if your node IP is connected!
It will show up as soon as the blocks are checked and the raspi is running.
Well done!
Now you are running a full node, with a small Blockchain and got it working in Minutes, not weeks!
I really hope, my little tutorial worked for you and your are part of the Node network now.
If you have problems or I made a mistake in this helper tut, just let me know and I will try to make it better.
Have fun and NODL!
the noob
tl;dr; (if you are a real noob start with the non-tl;dr version!)
tl;dr; PART ONE
1) Download & install / setup bitcoincore @ https://bitcoin.org/de/download
2) change dbcache to something smaller than your memory and download the whole Blockchain (120GB).
3) create a file called bitcoin.conf put the line prune=550 (or higher) in to activate pruning on win inside %appData%/bitcoin
4) Open ports 8333 on your Router to make this a full node with a smaller Blockchain.
You are running a full node on your PC.
tl;dr; PART TWO
1) Install jessie lite and the needed dependencies on your SDCard - Raspberry
( >git clone -b 0.14 https://github.com/bitcoin/bitcoin.git )
  • see tutorial for more info.
2) create a file called bitcoin.conf inside .bitcoin and add the same prune=Number you had on your PC.
3) transfer the pruned folders BLOCKS and CHAINSTATE to the Raspberry Folder .bitcoin
4)Start "bitcoind &"
5) let everything sync
6) Make sure you have port 8333 opened on your router.
You are running a full node on your Raspberry with a super small Blockchain (I put all on a 8GB SDcard)

A Guide to Keeping Keys Offline Using Armory +rPi

Hi Redditors.
I am going to post in this thread my experiences in getting my Desktop (Debian) machine running Armory in watch-only mode, and coupling that with an offline Raspberry Pi (which holds my private keys) for signing the transactions previously made in watch-only mode.
I actually compiled Armory from source directly on my Pi. This guide is probably more for the bitcoin 'power user', as to run Armory online, and broadcast the signed transactions, you need to have a bitcoin full node running (bitcoind).
Basic requirements:
Aimed-for Setup:
I'll post the guide in digestible sections...

Section 1

I should begin by saying I installed source code from git, and got Armory to build the DB on my desktop initially, WITHOUT creating a wallet.. (This allowed me to debug what was going on a little!)
Go to Bitcoin.org, select Armory..
It leads to a Download from Git:
https://github.com/goatpig/BitcoinArmory/releases
Followed the procedure for Linux Debian verify code, compile, install, all straight-forward..
Began by running bitcoind, and telling Armory where to find it. This is the command I used, obviously it was all on one line and didn't include the arrows/explanations!:
python ArmoryQt.py \ --satoshi-datadir=/BlockChain/chain20180414/blocks \ # <-----(where my bitcoind blocks live) --datadir=/ArmoryDataDi \ # <-----(this is instead of ~/.armory) --dbdir=/ArmoryDataDidatabases # <-------(again, non std. place used for Armory's databases.. my choice.) 
So, on the Desktop, after the initial "build databases"
(NB the initial "Build Databases" took about 1.5h and my two CPUs were maxed the whole time, Temps up to 62C. Not ideal; Im not in a rush!)
I then wanted to import a watch-only wallet.
Before I did this, I took a full backup of the Armory data dir:
/ArmoryDataDi
(or ~/.armory in a default installation).
I'd hate to have to make Armory do another full sync with the bitcoind node!

Section 2

Next step: offline wallet (with Private Keys) is on a Raspberry Pi.
I downloaded the source and managed to compile it on the pi itself! :)
Though there were some gymnastics needed to setup the Pi.
My Pi is running Raspbian based on Wheezy.. quite old!
I did the following on the Pi:
apt-get update apt-get upgrade (<---took about an hour!) apt-get install autotools-dev apt-get install autoconf 
Then I followed the instructions exactly as I had done for my Debian Desktop machine, EXCEPT:
I had to increase the Pi's swap space. I upped it from 100Mb to 400Mb.
The compilation took 7 hours, and my poor SD card got a thrashing.
But after compilation, I put the Swap back to 100Mb and Armory runs ok with about 150Mb of memory (no swap needed).
Swap increase on the Pi:
use your favourite editor, and open the file /etc/dphys-swapfile
add/change the following line:
CONF_SWAPSIZE=400 
Then, REBOOT the Pi:
sudo shutdown -h -P now 
Once the compilation was done on the Pi, put the swap back, rebooted and created an Armory wallet.
I added manual entropy and upped the encryption 'time' from 250ms to 2500ms - since the Pi is slow, but I'll be happy to wait for more iterations in the Key Derivation Function.
Once the wallet was created, it obviously prompts you for backup.
I want to add a private key of my own (i.e. import), so don't do the backup until this is over.
I import my Private Key, and Armory checks that this corresponds to a Public Key, which I check is correct.
This is the point now where the Pi storage medium (e.g an SD card) has to be properly destroyed if you ever get rid of it.
I had thought that now would be a good time to decide if your new wallet will generate Segwit receiving addresses, and also addresses used to receive 'change' after a transaction..
But it seems Armory WON'T let you switch to P2SH-P2WPKH unless your Armory is connected to a node offering "WITNESS" service.
Obviously, my Pi is offline and will never connect to a node, so the following will not work on the Pi:
NB: I thought about setting this on the Debian "watch-only" wallet, but that would surely mean doom, as the Pi would not know about those addresses and backups might not keep them.. who knows...
So, end result:- no segwit for me just yet in my offline funds.

--If anyone can offer a solution to this, I'd be very grateful--

Section 3

Ok, now this is a good point to back up your wallet on the Pi. It has your imported keys. I choose a Digital Backup - and put it on a USB key, which will never touch the internet and will be stored off-site. I also chose to encrypt it, because I'm good with passwords..
NB: The Armory paper backup will NOT back up your imported private keys, so keep those somewhere if you're not sweeping them. It would be prudent to have an Armory paper backup anyway, but remember it will likely NOT help you with that imported key.
Now for the watch-only copy of the wallet. I want to get the "watch-only" version onto my Desktop Debian machine.
On the Pi, I created (exported to a USB key) a "watching-only" copy of my wallet.
I would use the RECOMMENDED approach, export the "Entire Wallet File".
As you will see below, I initially exported only the ROOT data, which will NOT capture the watching-only part of the Private Key I entered manually above (i.e. the public Key!).
Now, back on the Debian Desktop machine...
I stopped all my crontab jobs; just give Armory uninterrupted CPU/memory/disk...
I also stopped bitcoind and made a backup prior to any watch-only wallet being imported.
I already made a backup of Armory on my Desktop, before any wallet import.
(this was needed, as I made a mistake.. see below)
So on the Debian Desktop machine, I begin by firing up bitcoind.
my command for this is:
./bitcoind -daemon -datadir=/BlockChain/chain20180414 -dbcache=400 -maxmempool=400 

Section 4

I try running Armory like this:
(I'm actually starting Armory from a script - StartArm.sh)
Inside the script StartArm.sh, it has the line:
python ArmoryQt.py --ram-usage=4 --satoshi-datadir=/BlockChain/chain20180414/blocks --datadir=/ArmoryDataDi --dbdir=/ArmoryDataDidatabases 
I know from bitter experience that doing a scan over the blockchain for a new wallet takes a looong time and a lot of CPU, and I'd like it to play nicely; not gobble all the memory and swap and run my 2xCPUs both at 100% for four hours...
So... I aim to run with --ram-usage=X and --thread-count=X
(For me in the end, X=1 but I began with X=4)
I began with --ram-usage=4 (<--- = 4x128Mb)
The result is below...
TypeError: cannot concatenate 'str' and 'int' objects 
It didn't recognise the ram-usage and carried on, crippling my Debian desktop PC.
This is where it gets dangerous; Armory can gobble so much memory and CPU that the windowing environment can cease up, and it can take over 30 minutes just to exit nicely from bitcoind and ArmoryDB.
So, I ssh to the machine from another computer, and keep an eye on it with the command
"free -h" 
I'd also be able to do a "sudo reboot now" if needed from here.

Section 5

So, trying to get my --ram-usage command recognised, I tried this line (added quotes):
python ArmoryQt.py --ram-usage="4" --satoshi-datadir=/BlockChain/chain20180414/blocks --datadir=/ArmoryDataDi --dbdir=/ArmoryDataDidatabases 
But no, same error...
Loading Armory Engine: Armory Version: 0.96.4 Armory Build: None PyBtcWallet Version: 1.35 Detected Operating system: Linux OS Variant : ('debian', '9.4', '') User home-directory : /home/ Satoshi BTC directory : /BlockChain/chain20180414 Armory home dir : /ArmoryDataDi ArmoryDB directory : /ArmoryDataDidatabases Armory settings file : /ArmoryDataDiArmorySettings.txt Armory log file : /ArmoryDataDiarmorylog.txt Do wallet checking : True (ERROR) ArmoryUtils.py:3723 - Unsupported language specified. Defaulting to English (en) (ERROR) ArmoryQt.py:1833 - Failed to start Armory database: cannot concatenate 'str' and 'int' objects Traceback (most recent call last): File "ArmoryQt.py", line 1808, in startArmoryDBIfNecessary TheSDM.spawnDB(str(ARMORY_HOME_DIR), TheBDM.armoryDBDir) File "/BitcoinArmory/SDM.py", line 387, in spawnDB pargs.append('--ram-usage=' + ARMORY_RAM_USAGE) TypeError: cannot concatenate 'str' and 'int' objects 

Section 6

So, I edit the Armory python file SDM.py:
if ARMORY_RAM_USAGE != -1: pargs.append('--ram-usage=4') #COMMENTED THIS, SO I CAN HARDCODE =4 # ' + ARMORY_RAM_USAGE) 
Running it, I now have acknowledgement of the --ram-usage=4:
(WARNING) SDM.py:400 - Spawning DB with command: /BitcoinArmory/ArmoryDB --db-type="DB_FULL" --cookie --satoshi-datadir="/BlockChain/chain20180414/blocks" --datadir="/ArmoryDataDi" --dbdir="/ArmoryDataDidatabases" --ram-usage=4 
Also, even with ram-usage=4, it used too much memory, so I told it to quit.
It took over 30 minutes to stop semi-nicely. The last thing it reported was:
ERROR - 00:25:21: (StringSockets.cpp:351) FcgiSocket::writeAndRead FcgiError: unexpected fcgi header version 
But that didn't seem to matter or corrupt the Armory Database, so I think it's ok.
So, I get brave and change SDM.py as below, and I make sure my script has a command line for --ram-usage="ABCDE" and --thread-count="FGHIJ"; the logic being that these strings "ABCDE" will pass the IF criteria below, and my hardcoded values will be used...
if ARMORY_RAM_USAGE != -1: pargs.append('--ram-usage=1') #COMMENTED THIS, SO I CAN HARDCODE =1 # ' + ARMORY_RAM_USAGE) if ARMORY_THREAD_COUNT != -1 pargs.append('--thread-count=1') #COMMENTED THIS, SO I CAN HARDCODE =1 #' + ARMORY_THREAD_COUNT) 
So, as usual, I use my script and start this with: ./StartArm.sh
(which uses command line:)
python ArmoryQt.py --ram-usage="ABCDE" --thread-count="FGHIJ" --satoshi-datadir=/BlockChain/chain20180414/blocks --datadir=/ArmoryDataDi --dbdir=/ArmoryDataDidatabases 
(this forces it to use my hard-coded values in SDM.py...)
So, this is the command which it reports that it starts with:
(WARNING) SDM.py:400 - Spawning DB with command: /BitcoinArmory/ArmoryDB --db-type="DB_FULL" --cookie --satoshi-datadir="/BlockChain/chain20180414/blocks" --datadir="/ArmoryDataDi" --dbdir="/ArmoryDataDidatabases" --ram-usage=1 --thread-count=1 
Again, this is where it gets dangerous; Armory can gobble so much memory and CPU that the windowing environment can cease up. So I ssh to the machine and keep an eye on it with:
"free -h" 

Section 7

So, on the Debian Desktop PC, I inserted the USB stick with the watch-only wallet I exported from the Pi.
Start Armory...
Import "Entire Wallet File" watch-only copy.
Wait 4 hours..
YAY!!!
After running Armory for about 30m, the memory usage dropped by 400m... wierd...
It took ~2 hours to get 40% completion.
After 3.5 hours it's almost there...
The memory went up to about 1.7Gb in use and 900Mb of Swap, but the machine remained fairly responsive throughout, apart from a few (10?) periods at the start, where it appeared to freeze for 10-30s at a time.
(That's where my ssh session came in handy - I could check the machine was still ok with a "free -h" command)
Now, I can:
Create an unsigned transaction on my Desktop,
Save the tx to USB stick,
Move to the Pi,
Sign the tx,
Move back to the Desktop,
Broadcast the signed tx.

Section 8

My initial Mistake:
This caused me to have to roll-back my Armory database, using the backup. so you should try to avoid doing this..
On the Pi, I exported only the ROOT data, which will NOT capture the watching-only part of the Private Key
It is RECOMMENDED to use the Digital Export of Entire Wallet File from the Pi when making a watch-only copy. If you just export just the "ROOT data", not the "Entire Wallet File", you'll have problems if you used an imported Private Key in the offline wallet, like I did.
Using the ROOT data text import, after it finished... my balance was zero. So,. I tried a Help->Rescan Balance (Restart Armory, takes 1minute to get back up and running) No Luck. Still zero balance.
So, I try Rescan Databases.. This will take longer. Nah.. no luck.
So, I tried again, thinking it might be to do with the fact that I imported the text "root data" stuff, instead of following the (Recommended) export of watching-wallet file.
So, I used my Armory backup, and wound back the ArmoryDataDi to the point before the install of the (zero balance) wallet. (you should not need to do this, as you will hopefully use the RECOMMENDED approach of exporting the "Entire Wallet File"!)

BTCPay Server + EPS + RTL - how?

I am trying to build a box with: - Linux Ubuntu 18.04 - BTCPay Server, using docker - EPS (Electrum Personal Server) - RTL (Ride the lightning)
I have the full bitcoin data synced in a folder already, from a previous bitcoin-qt/bitcoind instance.
  1. Can I install BTCPay Server with docker and then run beside another docker with EPS?
  2. I understand that RTL is already integrated into BTCPay, so I just have to update the server and activate it?
  3. Is possible to integrate also EPS into the BTCPay docker file, after the installation? Or is it in "works" to be integrated in the same docker installation/update server by BTCPay ?
  4. Is possible to run EPS without docker, but using the bitcoind from BTCPay docker instance?
  5. Is possible to connect a mobile wallet (ex. Samourai) to that bitcoind instance from BTCPay Server ?
  6. One last question: is there a procedure to backup all the BTCPay server settings, for in case of disaster recovery moment? So to restore all data at once after reinstall OS ?
This is very important thing, if I start to put a BTCPay server at work in production and the machine gets fucked, how easy is to restore it?
Please somebody can respond to these questions, not in a super technical manner so many others can understand it?
Maybe u/belcher_ and u/CardCollector1 or u/NicolasDorier can help with some answers here, please?
EDIT: I hope I don't have to add a meme to this post to bring more attention... seems that lately only memes are "important" here, subjects like this are ignored. EDIT2: 21 hours and still not any answer... fuck, nobody uses BTCPay ?

INTRODUCTION

According to wikipedia, Blockchain is originally known as bloc chain, It is a growing list of records known as blocks which is linked using cryptography, each of these blocks contain a cryptographic hash of the initial block, a transaction data and a time stamp.
Since its emergence in the year 2008, when Nakamoto satoshi discovered and introduced bitcoin, there has been serious efforts to integrate the blockchain technology into several aspects of various process of global business , The blockchain technology has been described as having the potential to disrupt many industries with immutability, low-cost transaction, and enhanced maximum security. So many other blockchain implementations have been deployed and developed with unique features designed to specific use-cases.
The blockchain technology has made possible to issue assets through a distributed ledger framework. With cryptocurrency tokens, Assets can be given economic value in order to validate and initiate transactional processes.

ADVANTAGES OF BLOCKCHAIN:

  1. Decentralised payment processing,
  2. Creating an immutable system of recording,
  3. Reducing Cost of Transaction and
  4. Enhanced Security.
  5. Now that we have reminded ourselves of what blockchain technology is, let’s look into the subject matter.

ABOUT WolfpackBOT

Masternode and Proof of Work X11 Blockchain
Wolfcoin Blockchain with X11 Proof of Work Mining and Masternode Reward Systems The Wolfcoin blockchain and network are both designed and engineered to ensure store of value, transactional speed and security, and fungibility. The main goal of the Wolfcoin blockchain is to facilitate fast and secure transactions with a governance that helps sustain the network for the benefit of all users. The Wolfcoin blockchain is a two-tier network comprised of a Proof of Work (PoW) consensus mechanism powered by miners and a Proof of Service (PoSe) system powered by masternodes.
The Wolfcoin blockchain is secured through Proof of Work (PoW) in which miners attempt to solve difficult problems with specialized computers. When a problem is solved, the miner receives the right to add a new block to the blockchain. If the problem was solved correctly, the miner is rewarded once the block is added.
The second tier, which is powered by masternodes, enables Wolfcoin to facilitate private and instant transactions with Private Send and Instant Send. Masternodes are also rewarded when miners discover new blocks.
The block reward is distributed with 80% going to the masternodes and 20% going to miners. The masternode system is referred to as Proof of Service (PoSe), since the masternodes provide crucial services that support the features of the network.
Masternodes also oversee the network and have the power to reject improperly formed blocks from miners. If a miner tried to take the entire block reward for themselves, the masternode network would orphan the block ensuring that it would not be added to the blockchain.
In short, miners power the first tier, which is the basic sending and receiving of funds and prevention of double spending. Masternodes power the second tier, which provide the added features that make Wolfcoin different from other cryptocurrencies. Masternodes do not mine, and mining computers cannot serve as masternodes.
Additionally, each masternode is “secured” by 10,000 WOLF. Those WOLF remain under the sole control of their owner at all times. The funds are not locked in any way; however, if enough of the funds are moved or spent to cause the user’s holdings to drop below 10,000 Wolfcoin, the associated masternode will go offline and stop receiving rewards.
By pre-ordering your WolfpackBOT subscription, you will also receive Wolfcoin as a reward that can be utilized in the following ways:
  • Redeemable for WolfpackBOT subscriptions
  • Redeemable for the WolfBOX Console
  • Redeemable for WolfpackBOT and Wolfcoin apparel and merchandise
  • Fungible utility that can be exchanged for like value on exchanges
When you hold at least 10,000 Wolfcoin in your Wolfcoin wallet connected to a static IP address, you will become a masternode, meaning you will have a chance to receive 80 percent of the block reward every sixty seconds.
