https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/126.96.36.199 Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that. Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap. We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout. Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.
Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now. Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date. The transition height is also when the team requirement will be relaxed for the network.
Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.
The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use. There are so many goodies here it is hard to summarize them all. I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures. The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!
Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.
Network magnitude unit pinned to a static value of 0.25
Max research reward allowed per block raised to 16384 GRC (from 12750 GRC)
New CPIDs begin accruing research rewards from the first superblock that contains the CPID instead of from the time of the beacon advertisement
500 GRC research reward limit for a CPID's first stake
6-month expiration for unclaimed rewards
10-block spacing requirement between research reward claims
Rolling 5-day payment-per-day limit
Legacy tolerances for floating-point error and time drift
The need to include a valid copy of a CPID's magnitude in a claim
10-block emission adjustment interval for the magnitude unit
One-time beacon activation requires that participants temporarily change their usernames to a verification code at one whitelisted BOINC project
Verification codes of pending beacons expire after 3 days
Self-service beacon removal
Burn fee for beacon advertisement increased from 0.00001 GRC to 0.5 GRC
Rain addresses derived from beacon keys instead of a default wallet address
Beacon expiration determined as of the current block instead of the previous block
The ability for developers to remove beacons
The ability to sign research reward claims with non-current but unexpired beacons
As a reminder:
Beacons expire after 6 months pass (180 days)
Beacons can be renewed after 5 months pass (150 days)
Renewed beacons must be signed with the same key as the original beacon
Magnitudes less than 1 include two fractional places
Magnitudes greater than or equal to 1 but less than 10 include one fractional place
A valid superblock must match a scraper convergence
Superblock popularity election mechanics
Yes/no/abstain and single-choice response types (no user-facing support yet)
To create a poll, a maximum of 250 UTXOs for a single address must add up to 100000 GRC. These are selected from the largest downwards.
Burn fee for creating polls scaled by the number of UTXOs claimed
50 GRC for a poll contract
0.001 GRC per claimed UTXO
Burn fee for casting votes scaled by the number of UTXOs claimed
0.01 GRC for a vote contract
0.01 GRC to claim magnitude
0.01 GRC per claimed address
0.001 GRC per claimed UTXO
Maximum length of a poll title: 80 characters
Maximum length of a poll question: 100 characters
Maximum length of a poll discussion website URL: 100 characters
Maximum number of poll choices: 20
Maximum length of a poll choice label: 100 characters
Magnitude, CPID count, and participant count poll weight types

This was also followed by the plan to release product updates, events, listings, or partnerships every week until the end of 2020. Bringing their promise and commitment true to the public, here are the activities that Swipe has released for the past two weeks: https://preview.redd.it/5ztwd3p3crh51.jpg?width=1280&format=pjpg&auto=webp&s=a5305d9e040318cfe9e3da0a3a721c88cbaf80ae Swipe Launches Staking/DeFi Swipe has recently launched its test network for Swipe Network Testnet Staking and, at the same time, announced its plans to launch a Decentralized Finance Lending/Earn application on Binance Smart Chain. With the launch of the Swipe Network testnet, users can use the Swipe Faucet to grab testnet-SXP to use on the decentralized finance application. Users will be able to bond SXP to the Swipe Network smart contract as collateral to ensure the guarantee of conversions for these exchanges. A reserve system in place to lock SXP and guarantee that the merchant and payment networks receive the exact fiat amount is in place as Swipe facilitates real-time conversions on-demand. Users will receive up 12% APY on their staked SXP within the Swipe Network off-chain and a variable rate for on-chain. Swipe plans to enable staked SXP to earn the processing fees it charges in the future as well on top of the collateral rewards from staking. Also, Swipe revealed its plans to launch a DeFi App on Binance Chain called SwipeFi, which will enable Binance Chain tokens to be used to earn interest on their supply of collateral to the protocol and borrow against their collateral directly on the Binance blockchain. Swipe (SXP) Trading Competition Last August 5 to 12, Swipe and Binance team have both committed a total of 100,000 SXP and 50,000 USDT in prizes to thank its users worldwide for their continued support and to also celebrate the Swipe acquisition and SXP/USDT listing in Futures, Margin and Spot markets. The contest was divided into three categories: a new user exclusive rewards, a trading competition, and the Lucky 99, which awarded users ranked 99th, 199th, 299th, 399th, and so forth until the 9999th place of the top 10,000 SXP traders based on their trading volume. Swipe x WBTC Swipe has partnered with WBTC Network and has officially been approved as a merchant for WBTC minting through the WBTC Network’s DAO Governance process. Swipe Wallet users will be able to benefit from instantly wrapping Bitcoin BTC to Wrapped Bitcoin (WBTC) and vice versa with just a few clicks. Swipe has also listed WBTC on the Swipe Wallet platform and Swipe Visa Card to enable users to buy, sell, exchange, and spend WBTC at over 60 million merchants worldwide. SXP on CoinDCX SXP, the native token of Swipe, is now listed and live on its second Indian Exchange CoinDCX. Trading for $SXP token is now live for CoinDCX users who wish to trade SXP/BTC and SXP/USDT. CoinDCX trading links for SXP: https://coindcx.com/trade/SXPBTC&https://coindcx.com/trade/SXPUSDT Wazirx AMA Session Swipe Chief Executive Officer (CEO) Joselito Lizarondo, held an AMA session with the Telegram community of Wazirx, a bitcoin exchange in India, last August 7. In the AMA session, Lizarondo answered questions about Swipe, Swipe Card, its new partnership with Binance, and the recent projects that the company has announced. The community also asked if Swipe is planning to bring its card services to India as it is one of the biggest crypto market countries at present. To read the whole summary of the AMA visit: https://blog.wazirx.com/ama-with-joselito-lizarondo-ceo-founder-of-swipe-summary/ New Swipe Product Manual Swipe has released a new “redefined” white paper under the title: Swipe Product Manual. The Swipe Product Manual was designed with simplicity in mind for easy and coherent descriptions of the Swipe ecosystem of products. This will describe all of Swipe’s current and future products that the team has planned. Technical descriptions and documentation will be made available, as required, per protocol, as some will have API access for developers. The Swipe Product Manual can be viewed by clicking here or by going to https://sw.pe/ProductManual or downloading https://swipe.io/ProductManual.pdf to your desktop. Swipe 0% Fees Starting Monday, August 17, Swipe Wallet and Swipe Card users will no longer have to pay any fees to buy, sell, and pay with crypto. Users can now purchase, sell, and convert cryptocurrencies to and from fiat currencies without the previous 1% fee. Swipe cardholders will also enjoy waived membership fees and free card shipping. Swipe Staking As Swipe prepares to launch the Swipe Network Staking mainnet, the Swipe Wallet application will support SXP staking. Users will enjoy staking rewards based on their SXP balances that are held on the Swipe Wallet beginning on August 23, 00:00 UTC. More details of the staking can be viewed at: https://medium.com/swipe/swipe-wallet-to-support-sxp-staking-acfab4589813 Swipe Reddit AMA In his first blog post on Medium, Swipe CEO Joselito Lizarondo answered the questions that the Reddit community asked regarding Swipe’s activities and plans for the future. He talked about the new partnership programs of Swipe, its newly released “Product Manual,” and the new roadmap, which will be kept in stealth “to focus on bringing maximum value to these announcements and products.” Read the whole transcript of Joselito Lizarondo’s AMA here: https://medium.com/swipe/swipe-reddit-ama-8-13-80690e2f6589 Swipe and Kava Partnership Swipe has formed a strategic partnership with Kava Labs to further grow the USDX DeFi Ecosystem as Swipe prepares to bring decentralized finance applications to the Binance Smart Chain. Swipe has also listed KAVA and USDX on the Swipe Wallet platform where users can buy and sell KAVA and USDX with a linked bank account or credit/debit card as well as enabled it to be converted and spent at over 60 million merchants worldwide with the Swipe Visa Card. $16M+ Ecosystem Rewards Program for BNB Holders on Binance Swipe is launching a 12-week-period $16,000,000 Ecosystem Rewards Program for BNB holders, starting August 17. This program aims to continue to promote the usage of Swipe products, including the Swipe Network Staking and Governance within a strong community. With Swipe’s partnership with Binance, a weekly distribution of 333,333.33 SXP will run to BNB holders on Binance.com. Know more about the Rewards Program here: https://medium.com/swipe/swipe-launches-16m-ecosystem-rewards-program-for-bnb-holders-on-binance-e79ffc9dc252 Swipe’s Chainlink Based Price Oracles Now Live Swipe has collaborated with Chainlink, the market-leading decentralized oracle network, to launch a live SXP-USD price oracle on the Ethereum mainnet. By switching to Chainlink, users receive stronger guarantees around trust and transparency in the payments process, as critical price feeds for the network are now completely decentralized and available to monitor on the blockchain. This decentralized infrastructure ensures that reward issuances and token burns only take place based on accurate, highly available, and tamper-proof on-chain prices that have no single point of failure or absolute truth. Users can independently verify the current price, how price updates occur, which nodes are providing data to the network, and more. This means users no longer need to rely on Swipe to produce fair conversion rates. --- Stay up-to-date with all the latest news from Swipe Website: https://swipe.io Twitter: https://twitter.com/SwipeWallet Facebook: https://facebook.com/Swipe Instagram: https://instagram.com/Swipe Medium: https://medium.com/Swipe Telegram: https://t.me/SwipeWallet & https://t.me/Swipe LinkedIn: https://www.linkedin.com/company/swipewallet YouTube: https://youtube.com/SwipeWallet

Upcoming Major Riecoin 0.20 Upgrade A new major Riecoin upgrade is planned, and includes a hard fork. Below is a summary of the changes so far and the hard fork improvements. More details can be found on BitcoinTalk. Feel free to ask Pttn there or on Discord if you have questions regarding the update. The first step of this upgrade was to update the base code to Bitcoin’s 0.20, which is done. You can find the experimental code at the Github repository. Experimental binaries can also be downloaded here. Despite their prerelease status, they should work fine, though please backup your wallets if you plan to use 0.20, just in case. Pool operators and other advanced Riecoin users should start looking into the changes and update their software accordingly, as well as closely follow the Riecoin Core development. Here is a list of notable changes from 0.16.3.1.
There were inconsistencies regarding the nTime and nBits positions in the Block Header. This is now fixed, with nTime always coming before nBits like for Bitcoin. Note that rieMiner needs an update to Solo Mine with 0.20, which is already available;
Testnet was reset. Additionally, the constellations for Testnet are no longer sextuplets, but quadruplets, and the minimum Difficulty was raised to 600. If you want to run a public Testnet node, please use the bootstrap found here and share your node IP;
The “getnetworkhashps” command was replaced by “getnetworkminingpower” and uses a new metric, standardized such that 1 correspond to mining a minimum difficulty block (Difficulty 304 in Mainnet or 600 in Testnet) every 150 s;
The GetBlockTemplate’s “primes” field is replaced by “constellations”, which gives a list of accepted constellations for mining. The “segwit” rule is now mandatory;
The “getprimes” RPC call is replaced by “getresult” and gives directly the base prime number, instead of all the prime numbers;
Generated addresses are now Bech32 by default;
The RegTest is now properly implemented (the PoW here is simply prime numbers). Most of the test units were ported to Riecoin;
And of course, all the Bitcoin features and bug fixes since 0.17 are now included in Riecoin. Read the Bitcoin Core change logs for more information.
The next step will be the hard fork, in order to improve Riecoin in multiple ways. Here is the list of planned changes.
The constellation pattern will be changed from sextuplets to septuplets (quintuplets in Testnet). Both possible patterns will be accepted, so the blockchain will provide more diverse results. One of them will have a chance to be a 8-tuple or longer, which would help a lot to beat records and improve the Riecoin’s scientific usefulness. Moreover, longer tuples are more practical as PoW;
The SuperBlock system will be removed. While records have indeed been broken this way, it also has significant drawbacks, like freezing the network during an hour every week and a complicated implementation that also confuses a lot of people;
The Difficulty Adjustment Algorithm will be updated to improve the network’s robustness and make the adjustment more dynamic. No particular algorithm has been chosen yet and the discussion is open;
The nOffset encoding will be updated in order to allow more efficient mining.
Once the development is advanced enough, a date will be chosen for the hard fork. Testnet will be hardforked first to ensure the well functioning of the implementation. Stay tuned!

Hey. I've been running a full bitcoin node for almost a year, but i want to run a LN node as well if its not so much of a hassle. I tried to find some previous posts but things get outdated pretty fast. I have a few channels open using the eclair app on my phone, but i assume this node is only useful when I'm using the phone? I assume it is better to run it on my home server instead. I know there are several software implementations available, but are any of them further along in UX? Eclair, LND and so on, as well as the wallets like ZAP, that counts as a node too right? Which one of these do you people recommend? I'm probably looking for a lightweight client with the bare minimum of features, while still participating in the lightning network. I'm using bitcoin core with my addresses as watch only, together with electrum personal server and a hardware wallet. Will the funds and addresses i have in the bitcoin core wallet somehow be visible through the LN node, will i be exposed in any significant way?
Reddcoin (RDD) Core Wallet v3.0.1 - January 09, 2020 Version 3.0.1 is the official release version of Reddcoin Core. It is available for download at Reddcoin Core's Github repository here: https://github.com/reddcoin-project/reddcoin/releases/tag/v3.0.1 This release features PoSV v2.supermajority activation and new staking ruleset (and minor misc fixes). v3.0.1 is still not yet MacOS Catalina compatible. We are still working and should have that fix issued very soon. Sincere apologies to our Mac-using ReddHeads. It is particularly important that all users upgrade, as once PoSV v2 is enforced, version 4 blocks will be rejected from the network entirely. Therefore v3.0.1 is a "strongly recommended" update for all users. Note: If you have already installed v3.0.0, this upgrade is not required. If you have not yet upgraded from v2.0.x or earlier, this is a REQUIRED upgrade. Please install the newest version v3.0.1 to avoid losing functionality during supermajority activation of PoSV v2. Reddcoin Core version 3.0.1 is now available from: https://github.com/reddcoin-project/reddcoin/releases Release Notes are available here and replicated below in this announcement: https://github.com/reddcoin-project/reddcoin/blob/mastedoc/release-notes.md This is a new major version release of Reddcoin. Previously, the original and subsequent versions of Reddcoin were taken from a fork of the Litecoin code base. With the release of Reddcoin V2.0.0, the code was based directly from a fork of Bitcoin. This allows for better source control and feature implementation from upstream changes into the future With the release of Reddcoin V3.0.0, the PoSV stake reward has been improved to allow for a target 5% network growth, in process re-incentivizing individual network stakers and providing for integrated dev support. Upgrading to this release is strongly recommended and required for continued operation. Once a supermajority of 90% is reached, old wallets will no longer accept the new v5 blocks. Please report bugs using the issue tracker at github: https://github.com/reddcoin-project/reddcoin/issues How to Upgrade If you are running an older version of Reddcoin, shut it down. Wait until it has completely shut down (which may take a few minutes for older versions). Run the installer (on Windows) or just copy over /Applications/Reddcoin-Qt (on Mac) or reddcoind/reddcoin-qt (on Linux). Start wallet. All done!
Reddcoin v3.0.0 introduced an updated PoSV method to better distribute staking rewards and target a overall 5% network growth. Staking and relay policy enhancements
To implement PoSV v2, Reddcoin Core's block templates are now for version 5 blocks only. When PoSV v2 consensus (Supermajority 9000/10000) is reached, only v5 blocks will be accepted by the network.This equates to approximately 90% of blocks being generated over 1 week period. Status at any time may be viewed in node debug.log Blockchain Download: Blockchain data for both testnet and mainnet along with instructions can be downloaded from github. https://github.com/reddcoin-project/bootstrap_files 3.0.1 changelog *83e212838 - John Nash, 2020-01-09 : really delete these files *3a1458ecd - Oliver Webb, 2020-01-08 : Added missing dependency libminiupnpc-dev for Jessie *d21915431 - Tiago Peralta, 2019-06-21 : Add vout to listtransactions/gettransaction *8d58ea7cf - Oliver Webb, 2020-01-08 : Script for downloading pre compiled binaries for Raspbian Jessie, Stretch or Buster *d4eced1bc - Oliver Webb, 2020-01-08 : Delete reddcoin_core_download_raspbian_stretch.sh *c5e9f91cf - Oliver Webb, 2020-01-08 : Delete reddcoin_core_download_raspbian_jessie.sh *5d5771b00 - Oliver Webb, 2020-01-08 : Delete reddcoin_core_download_raspbian_buster.sh *75c6ae91b - Oliver Webb, 2020-01-05 : add reddcoin-qt and remove starting daemon process *54c501787 - Oliver Webb, 2020-01-05 : add reddcoin-qt and remove starting daemon process *acb30a2b6 - Oliver Webb, 2020-01-05 : script files for Raspbian Jessie (also Stakebox) *cfddbe594 - John Nash, 2020-01-05 : Update copyright year and version *e46e5e7de - John Nash, 2020-01-05 : download script for pre compiled wallet *37386790a - John Nash, 2020-01-05 : change libssl deb packages links to github *9dbc772e6 - Oliver Webb, 2020-01-03 : download script for pre compiled wallet *857d697fd - Oliver Webb, 2020-01-03 : change libssl deb packages links to github *2cb74b9a8 - John Nash, 2019-12-31 : update copyright year *c641a1ab3 - Oliver Webb, 2019-12-30 : Raspberry Pi build script files for v3 wallet *a3f21a4a4 - John Nash, 2019-12-30 : add install script for building db4 update instructions for unix, osx, arm building using the db4 install script *5f6299b2a - John Nash, 2019-12-28 : docs: Update build notes for arm processors *465716c01 - John Nash, 2019-12-28 : test for arm devices *3fec3a535 - John Nash, 2018-02-02 : build: update source paths *5f6031ab4 - John Nash, 2019-12-28 : Scrypt n=1024 Pow hash based upon Colin Percival's Tarnsnap (2009) Modified by Artforz, coblee, pooler, wtogami, Nikolay Belikov, reddink *2fd4d91a0 - John Nash, 2019-12-24 : update copyright year *326828b36 - John Nash, 2019-12-24 : set release state true *8ebede0a6 - John Nash, 2019-12-24 : release notes *36df6fdfb - John Nash, 2019-12-23 : add check explictly for v5 blocks or greater *874dc1f0c - John Nash, 2019-12-17 : remove hardcoded global variable rearrange debug log output *763b25db8 - John Nash, 2019-12-17 : move copyright to new line *536baf635 - John Nash, 2019-12-17 : update version and set release state to false *cde9009f3 - John Nash, 2019-12-17 : update copyright year *ae41b7ed3 - John Nash, 2019-12-17 : set isSuperMajority to 90% for mainnet *e43e1c8ed - John Nash, 2019-12-10 : additional logging to verify isSuperMajority in the debug.log output *e31783cac - John Nash, 2019-12-05 : add/update public key for mainnet *405c6f002 - John Nash, 2019-12-05 : add log output for current inflation rate *9cc43c3f7 - John Nash, 2019-12-02 : determine calculated stake based on posv version *7baa3bf75 - John Nash, 2019-11-25 : check the posv transaction for correct pubkey *9ffa7ca38 - John Nash, 2019-11-21 : check for posv v1 or posv v2 blocks when calculating stake reward *39f7aad68 - John Nash, 2019-11-14 : add logging *0e283e6c3 - John Nash, 2019-11-13 : correct maths *74cbdeffd - John Nash, 2019-11-11 : use new posv v2 functions addidtional logging *35d7413b5 - John Nash, 2019-11-11 : add new proofofstakereward *3d917216c - John Nash, 2019-11-11 : get inflation adjustment *f63d17443 - John Nash, 2019-11-08 : add the developer output split fund output *ca263c9c9 - John Nash, 2019-11-05 : add dev key to chainparams *df6996ab0 - John Nash, 2019-11-05 : add block version checking *14b663479 - John Nash, 2019-11-05 : increase block version Credits Thanks to everyone who contributed to coding, testing and feedback for this release, notably:
Recap of Chromia AMA with the CEO of Chromia, @henrik_hjelte on BithumbGlobal telegram community dated 14.04.2020.
The AMA was moderated by u/Sidonpee. Sidonpee Let’s start with the introduction question: u/henrik_hjelteCan you introduce yourself to the community? What is your background? Henrik Hjelte I’m the CEO of ChromaWay, the company that started the Chromia project. My background is 30+ years as a developer (got payed first when I was 15), then studied Business and other things (politics and philosophy). Worked as Finance and IT consultant. THen wanted to be an entrepreneur. started a “web 2.0” startup about a free-speech internet. Hired our current CTO as a developer. THen joined his colored-coins project, the first token protocol ie the start of blockchain in 2012. Sorry. I’m now 50 years old, the math didn’t add up. That is why I’m the CEO and not CFO. Sidonpee Q1. What is Chromia? Can you tell us the technology behind it and the features that makes it unique? Henrik Hjelte Chromia is a new public blockchain based on the idea of integrating traditional databases, “Relational databases” with blockchain security. In the normal world outside blockchain, there is one technology that is in 100% of all enterprises and powers almost all webpages. It build Facebook, SAP, banks, blogging platforms. It is the relational database, or SQL database. Has been used for 30+ years and is still dominant with 85% market share. Why are people using it (NoSQL has been around for 15+ years)? Because it is the best way of managing data known to mankind. Now what is blockchani? It is a way to manage data that is shared. So if you agree that blockchain is about managing data, a relational database should be an obvious technology. Chromia is a general purpose blockchain with full smart contract capabilities, just that it is a lot easier to code, even complex applications. You code with an easy to learn new programming language that combines the power of SQL and “normal languages” but makes it secure in a blockchain context. Up to 1/10 the code-lines vs other blockchains. Sidonpee Q2. I often see Chromia and ChromaWay being used interchangeably, what is the relationship between the two? Henrik Hjelte The idea for Chromia and parts of the codebase originated from the company ChromaWay. It is actually one of the first blockchain companies, we had a project for tokens before ethereum called the “colored coins” project that led to us starting a company with a name take from the greek word for color. In 2015 we did what is now called stable-coin, EURO payments based on tokens on a public blockchain (tokens on bitcoin). It was for a bank LHV in Estonia. When we need to quickly find information, we could not search the blockchain and instead started to dump everything to a relational database, and then the idea started to grow to build a blockchain around this. So we did a private blockchain, intended for usecases in land-registration, banking and more. And then came up with the idea of doing a public blockchain for it. ChromaWay is the company that ideated Chromia and provided the first open source code for it. The Chromia pre-sale of tokens is now funding the development of Chromia, which is done by ChromaWay. When Chromia is released as a decentralized network, it will not be governed or run by ChromaWay. Of course we know it has to be decentralized, we understand the virtues of decentralization since 2012 when our CTO did the worlds first code for tokens, then started an open-source project which even inspired Vitalik (who soon quit and did his own thing). ChromaWay as a company will take a role as providing optional support and maintenance of Chromia projects (open for competition by other players). Sidonpee Q3. What’s the usefulness of $CHR token in Chromia ecosystem? Henrik Hjelte CHR can be used to pay for running dapps (normally by the developer of the dapp, not users). It can also be used as a mean of exchange between dapps, and to provide collateral/stake for providers (the ones running the blockchain), incentivizing good behaviour. Sidonpee Q4. What are the major milestones Chromia has achieved so far & what are your plans for 2020? Henrik Hjelte We have released Rell, the new programming language that is needed, and supported tooling (online Development Environment, downloadable IDE, documentation). We have release the first testnet in december, and at the same time another company 4irelabs has done the first dapp running on testnet. They could take our old code (done as a private blockchain), learn our new language Rell and port it to Chromia. That project is the Green Assets Wallet, green bond environmental impact reporting, run by a non-profit and with banks and institutions as users. Plans for 2020 is to both release a series of dApps to showcase how fantastic Chromia is, as well as continue to develop the platform. And when it is secure and good enough, we will release mainnet. Dapps are now being made by us as well as others. We do a decentralized social network framework call chromunity, now release to testnet. If is really cool, users can vote over moderators, and in the future users might even govern the complete application, how it can be updated. This is a great showcase for Chromia and why we use the slogan Power to the Public. Games coming are….
Mines of Dalarnia (by Workinman Interactive). An action game in a mine with blockchain rental of plots and stuff.
Krystopia 2, novas journey. A puzzle game done by Antler Interactive.
An indie game (not done by us so I don’t know how much I shoiul;d menton), but: it is a strategy game with FULL-LOGIC ON BLOCKHCHAIN yes ubercool that is why it is in caps
A secret demo-project that we do together with Antler to showcase the technical potential of Chromia platform.
More comin in 2020: Other dapps from other companies, one in impact-tech Games is a great way to show scalability and features BTW. I didn’t mention that Chromia is very scalable (everyone says that). But it is true, and with no tradeoff vs decentralization well, but I can also see enterprise projects going into more of public blockchain direction and hybrid, and there I think Chromia can really shine Sidonpee Q5. Revenue and adoption are the main points of all projects, can you tell us your Business model and how you generate revenue? Henrik Hjelte Chromia itself is a public network with no intrinsic business model, but participants in the network has. For example Providers make money from supplying quality hardware running dapps and the core software, dapp developers have individual business models. I already told about about ChromaWay/Chromia, but ChromaWay the company can provide support/maintenance and various services and add-ons for Chromia. It is very similar to how normal open-source vendors make money. Still up to competition from others, and without control over the Chromia network. We need it to be independent, otherwise it has no value. So it is sound business to have it decentralized as well, who would care otherwise? Sidonpee Q6. Regarding Chromia’s blockchain game (Minesofdalarnia), I’m quite sure that vast majority of game lovers would be anticipating for it release, could you please share with us the likely date it will be released? Henrik Hjelte Yes I can We have made very good progress recently, and I can happily share that MoD is planned to be released now in Q2. Anastasia Meanwhile you can check the Mines of Dalarnia Social Media page for recent updates on the game https://twitter.com/Chromia_Studios . We publish development updates there often. You can also sign-up for early access on https://www.minesofdalarnia.com 😉 Sidonpee Q7. Recently Chromia welcome Malcolm Lerider who was formally a Senior R&D Manager for Neo Blockchain as its new team and family member. When he was with Neo, he worked together with the community and was able to build the project from a top 50-something market cap project to a top 5 market cap project. Should we be expecting a replica of this at Chromia in the nearest future? Henrik Hjelte Yes. we are very excited to have Malcolm on-board, he is very knowledgeable in the area, and his expertise will definitely help with achieving that. Malcolm recently published an article where he introduced himself as a new member of Chromia. You can read it over here, if you haven’t already: https://medium.com/@MalcolmLeridei-am-joining-team-chromia-b25d527b5b6f Sidonpee Q8. Green Asset Wallet is absolutely an amazing starter in the Chromia blockchain! I would like to hear how you guys see the future business development possibilities in the next /6/12 months? Are there specific business areas, geographical locations, which you want to focus on most? Henrik Hjelte Thank you, yes, it is nice to have a project that is enterprise, and green too as the first one. We are working both to reach out but also support inbound requests for projects, I shared some above. Sometimes with business development, ChromaWAy might find a customeprospect but we don’t know where it will end. We think however, and Gartner too, that enterprise blockchain is gradually looking more at public blockchain projects. I think DeFI, tokenization of assets and things like that is interesting. Also, hopefully someone will be inspired by our solution to a free, open, user-governed decentralized social web, what we are now showing with Chromunity. Jack Dorsey, are you listening? We don’t have a particular geographical focus though, and really it is a generic platform use-case agnostic. We use games to show potential and scalability, but who knows maybe other applications will be more. It is not only up to us. Sidonpee Q9. Who are Chromia’s strategic investors and partners? What criteria/ process do you follow in evaluating your partnership deal with them? Henrik Hjelte We have some strategic investors and partners that have helped us during the way, I think maybe I should not mention them here with the risk of forgetting some of them, and I have no time to check if we should mention them, We (and the partner) look at how we can help each other on a case by case basis. There is no simple scorecard that we can follow. We try to avoid vanity partnership deals with no real meaning Sidonpee Q10. Why did Chromia develop a new language called Rell (Relational language) for dapp programming? Is the development of this new language really necessary? If yes, what are some of its unique features that cannot be found in other existing languages/environments? Henrik Hjelte Yes it was necessary. We need the features of relational alegbra. It is is a mathematical basis, very similar to logic, that has only had basically one implementation (SQL). But SQL was not secure enough and lacked features that can be used in a shared context like a blockchain. Everything needs to be secure. Also we wanted to add blockchain features, and make it look more like “normal programming”. Now some of the readers might ask? Can’t you do this on the EVM? No. Ethereum does simply not have anything similar to a relational database, and it would be technically infeasible. Some others may ask? How can you compete with the EVM /pet-project that have soo many developers etc…? My answer is : we are building on top of a virtual machine called Postgresql. Check how much time, optimization and money has been spent on that virtual machine… I think it is 20 years or more of development time, maybe more. Static typing is one feature we add that SQL doesn’t have (you can detect bugs at compile time) Yusuf What have been the major obstacle Chromia has faced in the past years while developing its idea? Whats the benefits for developers at Chromia? Why should we use Chromia instead of your competitors? Henrik Hjelte Obstacle: Technology/software developement is hard sometimes, difficult to predict when things are ready. Major benefits for developers: A LOT EASIER to code COMPLEX applications. I’m serious. If you are frustrated with blockchain development, take a look at the ease of use of Rell/Chromia LA LA DeFi is projected to buzz up in 2020 and is on everybody lips, what ROLES does Chromia play in the innovativeness and future of DeFi and how does it spearhead adoption of DeFi using blockchain solution? Henrik Hjelte Finance would be almost unthinkable without relational databases, the power core banking and more. An exchange is a table of bid and ask, and you match them. This is very easy to do with our tech. Sujit If any Dapp is created on Chromia Blockchain! Then is there any Gas fees charged by Chromia? Whats the concept of fees for Dapps on Chromia Blockchain? Henrik Hjelte No gas per user fee. The application pays for hosting, like a cloud. Normally the developer, unless the developer hands over the governenace of the application to someone else (maybe the users). Sujit If any Dapp is created on Chromia Blockchain! Then are there any Gas fees charged by Chromia? Whats the concept of fees for Dapps on Chromia Blockchain? Henrik Hjelte No gas per user fee. The application pays for hosting, like a cloud. Normally the developer, unless the developer hands over the governenace of the application to someone else (maybe the users). Mayowa Most blockchain projects have donated to COVID-19, but no news from Chromia. How will you contribute to fight COVID-19? Henrik Hjelte I had to answr this: I spent my free weekend time on a covid-19 hackathon the other week to do a solution to share medical equipment across countries. It is on our facebook I think u/anastasiazudina maybe you can share Anastasia We want to do our part for the ongoing covid19 crisis. Therefore, we were participating in the critical initiative HackTheCrisis. During the virtual hackathon, we tried to find good solutions for the new unique challenges that we now as a society are facing. https://www.facebook.com/chromaway/posts/2171037456376083 Mayowa Chromia creates a new lightweight programming language called RELL. How is this different and better for programmers than other popular language like Solidity, C++ and Java? Henrik Hjelte When you think about a large Java project done for say a bank. Ask the developers what OTHER thing they use? DO they ONLY use Java and store files on a server? Or do they also use a database. You will find that in 99.9% of cases they ALSO use a relational database. No one would EVER think about doing a solution to manage data with ONLY Java, C++ or whatever. Alejandro Urich For the development of the Dapps, do you only support Rell? Is it possible to program in another language that works with Chromia? Henrik Hjelte Because we require both relational database properties and more security than SQL, currently Rell is the only choice. It is really easy to learn, and in all cases if we allowed a “normal” language it would miss the feautures of relational databases. zafer metin Mr Henrik What are the advantages of Postchain used for Chromia? How is a consortium provided to database management with distributed control? Anastasia Thank you for your interest in Postchain uses! We have an article written what answers exactly those questions: https://blog.chromia.com/postchain-for-the-public-scaling-relational-blockchain/ Stay At Home As I know providers will be chosen by Chromaway, so how is it decentralized due to choice is totally in Chromaway? Henrik Hjelte Initial providers. We will migrate to a model where ChromaWAy has no more say than anyone else. But we need to bootstrap and start. Better to choose good initial providers. David Prince What is your long-term vision about the industry which Chromia is working at? Are you afraid someday there will be another Project with more innovative technology can replace Chromia? Henrik Hjelte Well. Blockchain is about managing data (in a shared context). I’m repeating myself but the market leading (85%) for 30+ years slution to manage data is a relational database. We are now the only relational database + blockchain. Who knows, maybe some better way to manage data will be invented? But even NoSQL who has been around and bark like a little dog has after a decade or more time only 15% market share. I think our tech will stand the mark of time. Sidonpee The AMA session with the Chronia team has finally come to an end. We’re greatly astonished having a well-articulated AMA session with Chronia’s CEO Henrik Hjelte u/henrik_hjelte and community/social media manager team Anastasia u/anastasiazudina in the community👨💻👌 Also, we are indeed overwhelmed by all our esteemed community members, for your support and enthusiasm for the project.

Huobi Lite currently supports MYR / HKD / VND / USD (Credit Card deposit only), with more to come in the future. Huobi Derivative Market (Huobi DM) Margin Trading Huobi Global launched Huobi Derivative Market (Huobi DM) exchange to selected countries. It provides margin trading, with very low daily loan interest rates of 0.1%. Margin Trading allows users to increase their investment exposure given a limited base principal to enjoy multiple returns. 3-Steps taken in Margin Trading:
Request for Loan
Trade on Margin (Long/Short)
Repay Margin Loan and Interest
With the introduction of Cross Margin on Huobi, users will have to explicitly input the respective margin type before executing the above 3 steps. Balances on the Cross Margin balance does not show on the Isolated Margin balance. Huobi Futures Huobi Futures is a kind of digital currency derivatives. Users can make a profit from the rising/falling of digital currencies prices by going long or selling short based on their own judgment. The Huobi Futures Contract adopts spread delivery. When the contract expires, all open positions will be closed at the index-based last-hour arithmetic average price, instead of physical delivery. BTC/ETH/EOS/LTC/XRP/BCH/TRX/BSV/ETC Contracts are available on Huobi DM. Contracts are priced in USD, with corresponding digital currency (BTC/ETH/EOS/LTC/XRP/BCH/TRX respectively) as margin to open positions, and PnL is also settled in corresponding digital currency. Weekly, bi-weekly and quarterly contracts are available in Huobi DM. Weekly contracts will be settled on imminent Friday; Bi-weekly contracts will be settled on next Friday; Quarterly contracts will be settled on the last Friday of March, June, September and December. Choices of leverage: 1x, 5x, 10x, 20x Huobi Perpetual Swap Huobi introduced Perpetual Swaps on March 27, 2020 (GMT+8). Huobi Perpetual swap is a kind of digital currency derivatives. Users can make a profit from the rising/falling of digital currencies prices by going long or selling short based on their own judgment. Similar to a margin spot market, its price is close to the price of the underlying reference index. The main mechanism for anchoring spot prices is the cost of funds. Perpetual swap have no delivery date. Users can always hold it. Perpetual swap are settled every 8 hours. After each settlement, the realized profit/loss and unrealized profits/losses are transferred to the user account balance. Partial Liquidation Huobi Futures adopted partial liquidation to help position holders reduce liquidation risk. Users with large positions and high leverage bear high risk. Huobi Futures releases partial liquidation with the aim to lower possible losses due to high price volatility thus giving users better trading experience. Under partial liquidation mechanism, when liquidation is triggered, instead of liquidating all positions at once, the system reduces positions gradually till a grade whose margin ratio is great than 0. Full liquidation will only occur when the margin ratio of tier 1 upper limit net position still fails to be great than 0. Trading Fees The Huobi exchange has a fair trading fee structure. Every asset traded via Huobi Global is subject to a 0.2% trade fee, for both market makers and takers. Further, Huobi Global has introduced a tiered fee system which offers competitively lower fees for high volume traders. VIP membership gives access to various fee reductions and other benefits. Huobi Prime Huobi Prime, the Launchpad platform which we can call Direct Premium Offering (DPO), does share some similarities with initial exchange offerings (IEO) like Binance Launchpad, but it is unique as it is not a fundraising platform, and any coins purchased on the platform are immediately deposited into the users’ wallets and tradable on Huobi Global. Huobi Prime offers its users early access to the coins of premium projects, which can be bought using its native crypto currency, the Huobi Token. To avoid dumping, Huobi has implemented an innovative idea of a period of tiered price limits. Huobi FastTrack Huobit FastTrack, rebranded from Huobi Prime Lite, is a new listing model. Wherein, all participants will have a direct say in what projects are listed on Huobi Global and when. In addition, winning voters will get access to quality tokens at below market rates. The program also provides much needed exposure and a straightforward listing process.

Huobi wallet is the first wallet to expand support to cover seven stablecoins including, Paxos Standard Token (PAX), TrueUSD (TUSD), USD Coin (USDC), Gemini Dollar (GUSD), Dai (DAI), Stasis EURS (EURS), and Tether (USDT). Huobi Wallet is built based on the core principle of security-first. The wallet gives back its users, complete control of their private keys. In simple terms, You own your assets. The wallet is backed up with mnemonics, so in future when you want to import your wallet, it’s just simple few clicks. Currently, the wallet is compatible with both iOS and Android devices and you can download both from here (www.huobiwallet.com/en) Huobi Chain Huobi launched Huobi Chain’s Testnet (“the Testnet”) on February 29th 2020 (GMT+8). Huobi Chain is China’s autonomous cum compliant-ready blockchain platform, and is committed to providing a global, blockchain-based, digital asset infrastructure. Huobi Chain is committed to providing a high-performance, blockchain-based, global digital asset infrastructure. Once the Mainnet goes live, Huobi Chain will announce HT- related events: e.g. pledge HT to be a Super Node, etc. HT Lock & Mine (Huobi Pool) Huobi launched HT Lock and Mine operations on 25th July 2019 (GMT+8). Users who lock HT tokens receive daily HPT rewards. Specific reward quantity will depend on lock option period selected, quantity locked and Huobi Pool’ s mining hash power and daily float. DPOS Rewards: All Huobi Global users with more than 1,000HPT holdings in their HBG account will receive DPOS mining rewards. Currently, token reward received under DPOS mining include EOS, TRX, CMT, ONG, IOST, ATOM, IRIS, LAMB。 Huobi Support Users of the Huobi exchange can access 24/7 live chat and Huobi help center. Those facing issues can also open a support ticket to have their issue resolved by an expert representative immediately. The Huobi Group has a very active YouTube channel, featuring Huobi Talk, where it posts user tutorials, detailed guides, and crypto currency information for traders. What I like the most about Huobi
An established platform that’s been operating since 2013, which is a long time in the crypto world.
Highly secured with decentralized exchange structure, which helps to resist DDOS attacks. Huobi has never suffered a large hack.
Huobi Security Reserve of 20000 BTC to compensate users’ loss of funds.
Dedicated, fast and 24/7 customer support.
Regulated in major jurisdictions.
User interface is very smooth and clean.
Over 230 crypto assets are available.
User education program is good initiative.
Separate trading desk for institution and firm size users.
Very transparent about its operations, listings and projects.
Huobi Wallet is secured and very easy to operate.
Huobi mobile app is smooth and very easy to use.
Has taken serious steps towards avoiding wash trading.
Impressive array of trading pairs.
Has given more important on community participation, like voting for listing, mining pool, Huobi Knights program etc.
I like Huobi Prime because of following reasons: -
(a) Purchased tokens are immediately deposited into user’s accounts, (b) As projects launch exclusively through Huobi Prime from day one, all users get assets at the best price. (c) Tiered price limits on the platform protect both investors and projects from immediate dump.
Huobi screen projects and launches which are only the best. I don’t have to worry about poor or scammy projects.
Burning of HT is a great move and it would benefit long term holders.
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.
Builds are now done through Gitian
Calls to getblocktemplate will fail if the segwit rule is not specified. Calling getblocktemplate without segwit specified is almost certainly a misconfiguration since doing so results in lower rewards for the miner. Failed calls will produce an error message describing how to enable the segwit rule.
A warning is printed if an unrecognized section name is used in the configuration file. Recognized sections are [test], [main], and [regtest].
Four new options are available for configuring the maximum number of messages that ZMQ will queue in memory (the "high water mark") before dropping additional messages. The default value is 1,000, the same as was used for previous releases.
The rpcallowip option can no longer be used to automatically listen on all network interfaces. Instead, the rpcbind parameter must be used to specify the IP addresses to listen on. Listening for RPC commands over a public network connection is insecure and should be disabled, so a warning is now printed if a user selects such a configuration. If you need to expose RPC in order to use a tool like Docker, ensure you only bind RPC to your localhost, e.g. docker run [...] -p 127.0.0.1:1441:1441 (this is an extra :1441 over the normal Docker port specification).
The rpcpassword option now causes a startup error if the password set in the configuration file contains a hash character (#), as it's ambiguous whether the hash character is meant for the password or as a comment.
The whitelistforcerelay option is used to relay transactions from whitelisted peers even when not accepted to the mempool. This option now defaults to being off, so that changes in policy and disconnect/ban behavior will not cause a node that is whitelisting another to be dropped by peers.
A new short about the JSON-RPC interface describes cases where the results of anRPC might contain inconsistencies between data sourced from differentsubsystems, such as wallet state and mempool state.
A new document introduces Groestlcoin Core's BIP174 interface, which is used to allow multiple programs to collaboratively work to create, sign, and broadcast new transactions. This is useful for offline (cold storage) wallets, multisig wallets, coinjoin implementations, and many other cases where two or more programs need to interact to generate a complete transaction.
The output script descriptor (https://github.com/groestlcoin/groestlcoin/blob/mastedoc/descriptors.md) documentation has been updated with information about new features in this still-developing language for describing the output scripts that a wallet or other program wants to receive notifications for, such as which addresses it wants to know received payments. The language is currently used in multiple new and updated RPCs described in these release notes and is expected to be adapted to other RPCs and to the underlying wallet structure.
A new --disable-bip70 option may be passed to ./configure to prevent Groestlcoin-Qt from being built with support for the BIP70 payment protocol or from linking libssl. As the payment protocol has exposed Groestlcoin Core to libssl vulnerabilities in the past, builders who don't need BIP70 support are encouraged to use this option to reduce their exposure to future vulnerabilities.
The minimum required version of Qt (when building the GUI) has been increased from 5.2 to 5.5.1 (the depends system provides 5.9.7)
getnodeaddresses returns peer addresses known to this node. It may be used to find nodes to connect to without using a DNS seeder.
listwalletdir returns a list of wallets in the wallet directory (either the default wallet directory or the directory configured bythe -walletdir parameter).
getrpcinfo returns runtime details of the RPC server. Currently, it returns an array of the currently active commands and how long they've been running.
deriveaddresses returns one or more addresses corresponding to an output descriptor.
getdescriptorinfo accepts a descriptor and returns information aboutit, including its computed checksum.
joinpsbts merges multiple distinct PSBTs into a single PSBT. The multiple PSBTs must have different inputs. The resulting PSBT will contain every input and output from all the PSBTs. Any signatures provided in any of the PSBTs will be dropped.
analyzepsbt examines a PSBT and provides information about what the PSBT contains and the next steps that need to be taken in order to complete the transaction. For each input of a PSBT, analyze psbt provides information about what information is missing for that input, including whether a UTXO needs to be provided, what pubkeys still need to be provided, which scripts need to be provided, and what signatures are still needed. Every input will also list which role is needed to complete that input, and analyzepsbt will also list the next role in general needed to complete the PSBT. analyzepsbt will also provide the estimated fee rate and estimated virtual size of the completed transaction if it has enough information to do so.
utxoupdatepsbt searches the set of Unspent Transaction Outputs (UTXOs) to find the outputs being spent by the partial transaction. PSBTs need to have the UTXOs being spent to be provided because the signing algorithm requires information from the UTXO being spent. For segwit inputs, only the UTXO itself is necessary. For non-segwit outputs, the entire previous transaction is needed so that signers can be sure that they are signing the correct thing. Unfortunately, because the UTXO set only contains UTXOs and not full transactions, utxoupdatepsbt will only add the UTXO for segwit inputs.
getpeerinfo now returns an additional minfeefilter field set to the peer's BIP133 fee filter. You can use this to detect that you have peers that are willing to accept transactions below the default minimum relay fee.
The mempool RPCs, such as getrawmempool with verbose=true, now return an additional "bip125-replaceable" value indicating whether thetransaction (or its unconfirmed ancestors) opts-in to asking nodes and miners to replace it with a higher-feerate transaction spending any of the same inputs.
settxfee previously silently ignored attempts to set the fee below the allowed minimums. It now prints a warning. The special value of"0" may still be used to request the minimum value.
getaddressinfo now provides an ischange field indicating whether the wallet used the address in a change output.
importmulti has been updated to support P2WSH, P2WPKH, P2SH-P2WPKH, and P2SH-P2WSH. Requests for P2WSH and P2SH-P2WSH accept an additional witnessscript parameter.
importmulti now returns an additional warnings field for each request with an array of strings explaining when fields are being ignored or are inconsistent, if there are any.
getaddressinfo now returns an additional solvable Boolean field when Groestlcoin Core knows enough about the address's scriptPubKey, optional redeemScript, and optional witnessScript for the wallet to be able to generate an unsigned input spending funds sent to that address.
The getaddressinfo, listunspent, and scantxoutset RPCs now return an additional desc field that contains an output descriptor containing all key paths and signing information for the address (except for the private key). The desc field is only returned for getaddressinfo and listunspent when the address is solvable.
importprivkey will preserve previously-set labels for addresses or public keys corresponding to the private key being imported. For example, if you imported a watch-only address with the label "coldwallet" in earlier releases of Groestlcoin Core, subsequently importing the private key would default to resetting the address's label to the default empty-string label (""). In this release, the previous label of "cold wallet" will be retained. If you optionally specify any label besides the default when calling importprivkey, the new label will be applied to the address.
getmininginfo now omits currentblockweight and currentblocktx when a block was never assembled via RPC on this node.
The getrawtransaction RPC & REST endpoints no longer check the unspent UTXO set for a transaction. The remaining behaviors are as follows:
If a blockhash is provided, check the corresponding block.
If no blockhash is provided, check the mempool.
If no blockhash is provided but txindex is enabled, also check txindex.
unloadwallet is now synchronous, meaning it will not return until the wallet is fully unloaded.
importmulti now supports importing of addresses from descriptors. A desc parameter can be provided instead of the "scriptPubKey" in are quest, as well as an optional range for ranged descriptors to specify the start and end of the range to import. Descriptors with key origin information imported through importmulti will have their key origin information stored in the wallet for use with creating PSBTs.
listunspent has been modified so that it also returns witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output.
createwallet now has an optional blank argument that can be used to create a blank wallet. Blank wallets do not have any keys or HDseed. They cannot be opened in software older than 2.18.2. Once a blank wallet has a HD seed set (by using sethdseed) or private keys, scripts, addresses, and other watch only things have been imported, the wallet is no longer blank and can be opened in 2.17.2. Encrypting a blank wallet will also set a HD seed for it.
signrawtransaction is removed after being deprecated and hidden behind a special configuration option in version 2.17.2.
The 'account' API is removed after being deprecated in v2.17.2 The 'label' API was introduced in v2.17.2 as a replacement for accounts. See the release notes from v2.17.2 for a full description of the changes from the 'account' API to the 'label' API.
addwitnessaddress is removed after being deprecated in version 2.16.0.
generate is deprecated and will be fully removed in a subsequent major version. This RPC is only used for testing, but its implementation reached across multiple subsystems (wallet and mining), so it is being deprecated to simplify the wallet-node interface. Projects that are using generate for testing purposes should transition to using the generatetoaddress RPC, which does not require or use the wallet component. Calling generatetoaddress with an address returned by the getnewaddress RPC gives the same functionality as the old generate RPC. To continue using generate in this version, restart groestlcoind with the -deprecatedrpc=generate configuration option.
Be reminded that parts of the validateaddress command have been deprecated and moved to getaddressinfo. The following deprecated fields have moved to getaddressinfo: ismine, iswatchonly,script, hex, pubkeys, sigsrequired, pubkey, embedded,iscompressed, label, timestamp, hdkeypath, hdmasterkeyid.
The addresses field has been removed from the validateaddressand getaddressinfo RPC methods. This field was confusing since it referred to public keys using their P2PKH address. Clients should use the embedded.address field for P2SH or P2WSH wrapped addresses, and pubkeys for inspecting multisig participants.
A new /rest/blockhashbyheight/ endpoint is added for fetching the hash of the block in the current best blockchain based on its height (how many blocks it is after the Genesis Block).
A new Window menu is added alongside the existing File, Settings, and Help menus. Several items from the other menus that opened new windows have been moved to this new Window menu.
In the Send tab, the checkbox for "pay only the required fee" has been removed. Instead, the user can simply decrease the value in the Custom Fee rate field all the way down to the node's configured minimumrelay fee.
In the Overview tab, the watch-only balance will be the only balance shown if the wallet was created using the createwallet RPC and thedisable_private_keys parameter was set to true.
The launch-on-startup option is no longer available on macOS if compiled with macosx min version greater than 10.11 (useCXXFLAGS="-mmacosx-version-min=10.11" CFLAGS="-mmacosx-version-min=10.11" for setting the deployment sdkversion)
A new groestlcoin-wallet tool is now distributed alongside Groestlcoin Core's other executables. Without needing to use any RPCs, this tool can currently create a new wallet file or display some basic information about an existing wallet, such as whether the wallet is encrypted, whether it uses an HD seed, how many transactions it contains, and how many address book entries it has.
Since version 2.16.0, Groestlcoin Core's built-in wallet has defaulted to generating P2SH-wrapped segwit addresses when users want to receive payments. These addresses are backwards compatible with all widely used software. Starting with Groestlcoin Core 2.20.1 (expected about a year after 2.18.2), Groestlcoin Core will default to native segwitaddresses (bech32) that provide additional fee savings and other benefits. Currently, many wallets and services already support sending to bech32 addresses, and if the Groestlcoin Core project sees enough additional adoption, it will instead default to bech32 receiving addresses in Groestlcoin Core 2.19.1. P2SH-wrapped segwit addresses will continue to be provided if the user requests them in the GUI or by RPC, and anyone who doesn't want the update will be able to configure their default address type. (Similarly, pioneering users who want to change their default now may set the addresstype=bech32 configuration option in any Groestlcoin Core release from 2.16.0 up.)
BIP 61 reject messages are now deprecated. Reject messages have no use case on the P2P network and are only logged for debugging by most network nodes. Furthermore, they increase bandwidth and can be harmful for privacy and security. It has been possible to disable BIP 61 messages since v2.17.2 with the -enablebip61=0 option. BIP 61 messages will be disabled by default in a future version, before being removed entirely.
The submitblock RPC previously returned the reason a rejected block was invalid the first time it processed that block but returned a generic "duplicate" rejection message on subsequent occasions it processed the same block. It now always returns the fundamental reason for rejecting an invalid block and only returns "duplicate" for valid blocks it has already accepted.
A new submitheader RPC allows submitting block headers independently from their block. This is likely only useful for testing.
The signrawtransactionwithkey and signrawtransactionwithwallet RPCs have been modified so that they also optionally accept a witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output. This is compatible with the change to listunspent.
For the walletprocesspsbt and walletcreatefundedpsbt RPCs, if thebip32derivs parameter is set to true but the key metadata for a public key has not been updated yet, then that key will have a derivation path as if it were just an independent key (i.e. no derivation path and its master fingerprint is itself).
The -usehd configuration option was removed in version 2.16.0 From that version onwards, all new wallets created are hierarchical deterministic wallets. This release makes specifying -usehd an invalid configuration option.
This release allows peers that your node automatically disconnected for misbehaviour (e.g. sending invalid data) to reconnect to your node if you have unused incoming connection slots. If your slots fill up, a misbehaving node will be disconnected to make room for nodes without a history of problems (unless the misbehaving node helps your node in some other way, such as by connecting to a part of the Internet from which you don't have many other peers). Previously, Groestlcoin Core banned the IP addresses of misbehaving peers for a period (default of 1 day); this was easily circumvented by attackers with multiple IP addresses. If you manually ban a peer, such as by using the setban RPC, all connections from that peer will still be rejected.
The key metadata will need to be upgraded the first time that the HDseed is available. For unencrypted wallets this will occur on wallet loading. For encrypted wallets this will occur the first time the wallet is unlocked.
Newly encrypted wallets will no longer require restarting the software. Instead such wallets will be completely unloaded and reloaded to achieve the same effect.
A sub-project of Bitcoin Core now provides Hardware Wallet Interaction (HWI) scripts that allow command-line users to use several popular hardware key management devices with Groestlcoin Core. See their project page for details.
This release changes the Random Number Generator (RNG) used from OpenSSL to Groestlcoin Core's own implementation, although entropy gathered by Groestlcoin Core is fed out to OpenSSL and then read back in when the program needs strong randomness. This moves Groestlcoin Core a little closer to no longer needing to depend on OpenSSL, a dependency that has caused security issues in the past. The new implementation gathers entropy from multiple sources, including from hardware supporting the rdseed CPU instruction.
On macOS, Groestlcoin Core now opts out of application CPU throttling ("app nap") during initial blockchain download, when catching up from over 100 blocks behind the current chain tip, or when reindexing chain data. This helps prevent these operations from taking an excessively long time because the operating system is attempting to conserve power.
How to Upgrade?
Windows If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer. OSX If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications. Ubuntu http://groestlcoin.org/forum/index.php?topic=441.0
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.
Groestlcoin Mainnet & Testnet supported
Multiple wallet support
Electrum - Support for both random and custom peers
Biometric + Pin authentication
Custom fee selection
Import mnemonic phrases via manual entry or scanning
BIP39 Passphrase functionality
Support for Segwit-compatible & legacy addresses in settings
Support individual private key sweeping
UTXO blacklisting - Accessible via the Transaction Detail view, this allows users to blacklist any utxo that they do not wish to include in their list of available utxo's when sending transactions. Blacklisting a utxo excludes its amount from the wallet's total balance.
Ability to Sign & Verify Messages
Support BitID for password-free authentication
Coin Control - This can be accessed from the Send Transaction view and basically allows users to select from a list of available UTXO's to include in their transaction.
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.
Simplified payment verification for fast mobile performance
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.
If a word is wrong, the tool will try to suggest the closest option.
If a word is missing or unknown, please type "?" instead and the tool will find all relevant options.
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).
Fixed size arithmetic
Fast Modular Inversion (Delayed Right Shift 62 bits)
SecpK1 Fast modular multiplication (2 steps folding 512bits to 256bits using 64 bits digits)
Use some properties of elliptic curve to generate more keys
SSE Secure Hash Algorithm SHA256 and RIPEMD160 (CPU)
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).
Ability to continue finding keys after first one is found
Includes warning on start-up if connected to the internet
Ability to output keys to a text file (And shows button to open that directory)
Show and hide the private key with a simple toggle switch
Show full output of commands
Ability to choose between Processor (CPU) and Graphics Card (GPU) ( NVidia ONLY! )
Features both a Light and Dark Material Design-Style Themes
Free software - MIT. Anyone can audit the code.
Written in C# - The code is short, and easy to review.
Groestlcoin WPF is an alternative full node client with optional lightweight 'thin-client' mode based on WPF. Windows Presentation Foundation (WPF) is one of Microsoft's latest approaches to a GUI framework, used with the .NET framework. Its main advantages over the original Groestlcoin client include support for exporting blockchain.dat and including a lite wallet mode. This wallet was previously deprecated but has been brought back to life with modern standards.
Works via TOR or SOCKS5 proxy
Can use bootstrap.dat format as blockchain database
Import/Export blockchain to/from bootstrap.dat
Import wallet.dat from Groestlcoin-qt wallet
Export wallet to wallet.dat
Use both groestlcoin-wpf and groestlcoin-qt with the same addresses in parallel. When you send money from one program, the transaction will automatically be visible on the other wallet.
Rescan blockchain with a simple mouse click
Works as a full node and listens to port 1331 (listening port can be changed)
Fast Block verifying, parallel processing on multi-core CPUs
Mine Groestlcoins with your CPU by a simple mouse click
All private keys are kept encrypted on your local machine (or on a USB stick)
Lite - Has a lightweight "thin client" mode which does not require a new user to download the entire Groestlcoin chain and store it
Free and decentralised - Open Source under GNU license
Fixed Import/Export to wallet.dat
Rescan wallet option
Change wallet password option
Address type and Change type options through *.conf file
Import from bootstrap.dat - It is a flat, binary file containing Groestlcoin blockchain data, from the genesis block through a recent height. All versions automatically validate and import the file "grs.bootstrap.dat" in the GRS directory. Grs.bootstrap.dat is compatible with Qt wallet. GroestlCoin-Qt can load from it.
In Full mode file %APPDATA%\Groestlcoin-WPF\GRS\GRS.bootstrap.dat is full blockchain in standard bootstrap.dat format and can be used with other clients.
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.
Use your own node
Uses less CPU and RAM than ElectrumX
Used intermittently rather than needing to be always-on
Doesn't require an index of every Groestlcoin address ever used like on ElectrumX
UPDATED – Android Wallet 7.38.1 - Main Net + Test Net
The app allows you to send and receive Groestlcoin on your device using QR codes and URI links. When using this app, please back up your wallet and email them to yourself! This will save your wallet in a password protected file. Then your coins can be retrieved even if you lose your phone.
Add confidence messages, helping users to understand the confidence state of their payments.
Handle edge case when restoring via an external app.
Count devices with a memory class of 128 MB as low ram.
Introduce dark mode on Android 10 devices.
Reduce memory usage of PIN-protected wallets.
Tapping on the app's version will reveal a checksum of the APK that was installed.
Fix issue with confirmation of transactions that empty your wallet.
Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets). Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet. Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.
You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments. The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
Limited Supply - There will only ever be 21,000,000 bitcoins created and they are issued in a predictable fashion, you can view the inflation schedule here. Once they are all issued Bitcoin will be truly deflationary. The halving countdown can be found here.
Open source - Bitcoin code is fully auditable. You can read the source code yourself here.
Accountable - The public ledger is transparent, all transactions are seen by everyone.
Decentralized - Bitcoin is globally distributed across thousands of nodes with no single point of failure and as such can't be shut down similar to how Bittorrent works.
Censorship resistant - No one can prevent you from interacting with the bitcoin network and no one can censor, alter or block transactions that they disagree with, see Operation Chokepoint.
Push system - There are no chargebacks in bitcoin because only the person who owns the address where the bitcoins reside has the authority to move them.
Low fee - Transactions fees can vary between a few cents and a few dollars depending on network demand and how much priority you wish to assign to the transaction. Most wallets calculate the fee automatically but you can view current fees here.
Borderless - No country can stop it from going in/out, even in areas currently unserved by traditional banking as the ledger is globally distributed.

Where can I buy bitcoins?
BuyBitcoinWorldwide.com and Howtobuybitcoin.io are helpful sites for beginners. You can buy or sell any amount of bitcoin and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also, check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Cashila or Bitwage. Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".
Securing your bitcoins
With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
If you prefer to "Be your own bank" and have direct control over your coins without having to use a trusted third party, there are many software wallet options here. If you want easy and secure storage without having to learn computer security best practices, then a hardware wallet such as the Trezor or Ledger is recommended. A more advanced option is to secure them yourself using paper wallets generated offline. Some popular mobile and desktop options are listed below and most are cross platform.
If you prefer to let third party "Bitcoin banks" manage your coins, try Coinbase or Xapo but be aware you may not be in control of your private keys in which case you would have to ask permission to access your funds and be exposed to third party risk.
Another interesting use case for physical storage/transfer is the Opendime. Opendime is a small USB stick that allows you to spend Bitcoin by physically passing it along so it's anonymous and tangible like cash. Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email! 2FA requires a second confirmation code to access your account, usually from a text message or app, making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out. If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. Bitseed is an easy option for getting set up. You can view the global node distribution here.
Just like any other form of money, you can also earn bitcoins by being paid to do a job.
You can also earn bitcoins by participating as a market maker on JoinMarket by allowing users to perform CoinJoin transactions with your bitcoins for a small fee (requires you to already have some bitcoins)
The following is a short list of ongoing projects that might be worth taking a look at if you are interested in current development in the bitcoin space.

1,000,000 per bitcoin
SI unit for micro i.e microlitre (μL) or micrometre (μm)
