https://github.com/gridcoin-network/Gridcoin-Research/releases/tag/five.zero.0.0 Finally! After over ten months of development and checking out, “Fern” has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that turned into began with the scraper (the choices “neural internet” rewrite) in “Denise” has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on pinnacle of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This gets rid of the choices group requirement at ultimate (see below), although there are numerous different essential upgrades besides that. Fern became a monumental mission. We needed to encode all the antique regulations energetic for the choices v10 block protocol in new code and make sure that the brand new code become one hundred% well suited. This had to be executed in such a manner as to clean out all of the vintage spaghetti and ring-fence it with tightly managed elegance implementations. We then wrote a completely new, simplified ruleset for research rewards and reengineered contracts (which incorporates beacon control, polls, and balloting) the usage of well classed code. The fundamentals of Gridcoin with this release are actually on a completely sound and maintainable footing, and the developers believe the choices codebase as updated right here will function the choices essential foundation for Gridcoin’s future roadmap. We had been trying out this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet constantly as it was developed to ensure compatibility with existing nodes. During the choices previous couple of months, we’ve done two non-public testnet forks and then the entire public testnet testing for v11 code (the new protocol which is what Fern implements). The builders have additionally been going for walks non-staking “sentinel” nodes on mainnet with this code to verify that the consensus rules are problem-loose for the choices legacy compatibility code on the choices broader mainnet. We accept as true with this amount of trying out is going to result in a clean rollout. Given the quantity of adjustments in Fern, I am providing TWO changelogs beneath. One is excessive stage, which summarizes the maximum extensive adjustments inside the protocol. The 2nd changelog is the choices detailed one inside the regular format, and offers you an inkling of the size of this release. Highlights Protocol Note that the choices protocol changes will now not come to be active till we pass the choices tough-fork transition height to v11, which has been set at 2053000. Given contemporary common block spacing, this need to occur around October 4, approximately one month from now. Note that to get all the beacons inside the network on the new protocol, we’re requiring ALL beacons to be demonstrated. A week (14 day) grace length is supplied via the choices code, starting at the time of the transition height, for humans presently protecting a beacon to validate the beacon and save you it from expiring. That approach that EVERY CRUNCHER ought to market it and validate their beacon AFTER the choices v11 transition (round Oct 4th) and BEFORE October 18th (or more exactly, 14 days from the choices actual date of the v11 transition). If you do no longer advertise and validate your beacon via this time, your beacon will expire and you’ll stop incomes studies rewards until you market it and validate a brand new beacon. This method has been made tons less complicated through a trendy beacon “wizard” that helps manipulate beacon advertisements and renewals. Once a beacon has been tested and is a v11 protocol beacon, the regular one hundred eighty day expiration regulations apply. Note, but, that the choices 180 day expiration on research rewards has been removed with the Fern replace. This manner that even as your beacon would possibly expire after one hundred eighty days, your earned studies rewards might be retained and may be claimed via advertising and marketing a beacon with the equal CPID and going via the validation procedure again. In different phrases, you do no longer lose any earned studies rewards if you do not stake a block inside one hundred eighty days and keep your beacon updated. The transition peak is likewise when the group requirement could be relaxed for the choices network. GUI Besides the beacon wizard, there are alternatives a number of upgrades to the GUI, which includes new UI transaction kinds (and icons) for staking the superblock, sidestake sends, beacon advertisement, vote casting, poll introduction, and transactions with a message. The principal display has been remodeled with a higher summary section, and better reputation icons. Several adjustments under the choices hood have improved GUI performance. And ultimately, the choices diagnostics were revamped. Blockchain The pockets sync velocity has been DRASTICALLY progressed. A decent machine with a great community connection ought to be able to sync the whole mainnet blockchain in much less than 4 hours. A fast machine with a sincerely fast network connection and a very good SSD can do it in about 2.5 hours. One of our goals turned into to lessen or do away with the choices reliance on snapshots for mainnet, and I think we’ve accomplished that aim with the brand new sync pace. We have also streamlined the in-reminiscence systems for the blockchain which shaves some memory use. There are such a lot of chocolates here it is difficult to summarize all of them. I would love to thank all of the members to this release, but particularly thank @cyrossignol, whose fantastic contributions shaped the choices backbone of this release. I might additionally like to pay special way to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and sharpening phase on testnet with checking out and repeated builds for all architectures. The developers are proud to provide this release to the choices network and we agree with this represents the choices start line for a true renaissance for Gridcoin! Summary Changelog Accrual Changed Most notably, nodes calculate research rewards without delay from the magnitudes in EACH superblock between stakes in place of the use of a two- or three- factor average based on a CPID’s modern-day importance and the choices value for the choices CPID whilst it last staked. For the ones long-timers within the community, this has been called “Superblock Windows,” and turned into first achieved in proof-of-concept shape by using @denravonska. Network significance unit pinned to a static cost of zero.25 Max studies reward allowed in keeping with block raised to 16384 GRC (from 12750 GRC) New CPIDs start accruing research rewards from the first superblock that carries the CPID in preference to from the time of the choices beacon commercial Removed 500 GRC research reward restriction for a CPID’s first stake 6-month expiration for unclaimed rewards 10-block spacing requirement between research reward claims Rolling five-day charge-according to-day limit Legacy tolerances for floating-point error and time flow The want to encompass a valid replica of a CPID’s importance in a declare 10-block emission adjustment c programming language for the value unit Beacons Added One-time beacon activation requires that individuals briefly alternate their usernames to a verification code at one whitelisted BOINC assignment Verification codes of pending beacons expire after 3 days Self-carrier beacon removal Changed Burn rate for beacon advertisement expanded from zero.00001 GRC to 0.five GRC Rain addresses derived from beacon keys in preference to a default pockets address Beacon expiration determined as of the modern-day block in place of the preceding block Removed The capacity for builders to take away beacons The capability to signal research reward claims with non-present day but unexpired beacons Unaltered As a reminder: Beacons expire after 6 months bypass (a hundred and eighty days) Beacons can be renewed after five months bypass (one hundred fifty days) Renewed beacons need to be signed with the identical key as the unique beacon Superblocks Added Magnitudes less than 1 include two fractional places Magnitudes greater than or same to at least one but less than 10 encompass one fractional location Changed A legitimate superblock have to fit a scraper convergence Removed Superblock reputation election mechanics Voting Added Yes/no/abstain and unmarried-preference response kinds (no user-going through support yet) Changed To create a ballot , a most of 250 UTXOs for a unmarried cope with need to add up to a hundred thousand GRC. These are decided on from the biggest downwards. Burn fee for creating polls scaled via the range of UTXOs claimed 50 GRC for a poll contract 0.001 GRC consistent with claimed UTXO Burn price for casting votes scaled with the aid of the choices
