Våra devs har gått in i turboläge för 4.0! Det är helt enkelt galet hur mycket arbete som läggs till i PIVX-koden för att göra den så mycket mer robust, ren, stabil, säker, snabb, funktionell och användbar ! Okej, kommer att försöka lugna ner lite … Sa jag att mängden arbete helt tokigt?!?! Okej, låt oss försöka igen …
Som jag sa … PIVX utvecklingen fortskrider extremt bra med många nya åtaganden efter grundliga tester, tillsammans med vår första offentliga segregerade test som visar den kommande 4.0 plånboken som körs på det förbättrade Proof of Staking-nätverket (PoS)!
Jag hör också att utvecklarna avsevärt kommer att förbättra masternode-delen av koden så att den fungerar bättre med staking och synkronisering. I slutet, förväntas du ha en fantastisk 4,0 plånbok som kommer att skapa ett ännu bättre 2020!
Segregerat Testnet med Cold Staking nu redo för offentliga tester!
Cold Staking (PR #955) is being put through its paces in a segregated testnet and now everyone can download the public testnet wallet to put it through its paces!
PIVX AMA on 4.0 with @Fuzzbawls
PIVX core developer Fuzzbawls have recently hosted a live AMA session on Discord and have answered a ton of questions about the recent developments, and some upcoming ones also! We are also considering doing this more regularly so please keep a look out for an announcement in our social media channels.
Core wallet v3.4 Release Refresher
- As a refresher for those who may have missed it, a mandatory PIVX wallet release v3.4.0 has been released on August 27, 2019, with a new Stake Modifier v2 (PR #983) plus other PoS hardening changes to prevent / eliminate stake grinding. If you are running an OLDER core wallet version than 3.4, make sure to upgrade to ensure your wallet is running on the correct network!
- Although the majority of exchanges have been upgraded to 3.4, it is still advisable to make a small test transaction before making larger transactions when making wallet to wallet transfers just in case.
- See detailed v3.4 release notes for a list of all changes & inclusions.
New PoS Time protocol v2
Core developer, random-zebra has been very busy working on a more robust Proof of Stake protocol for PIVX (PR #1002) with a host of improvements including difficulty algorithm changes, and removal of legacy PoW code engagement.
We can expect more consistent block times, more secure network, less energy consumption, more low-end device friendly, and fairer block distribution once this is merged. A detailed write up about this change is expected from the core developers once they are ready.
Community Developer Contributions
We are seeing more and more contributions by our community developers, and this activity can now be tracked on our new Community Developer Contributions Project page within the PIVX GitHub!

GitHub PR Highlights
- PIVX-Project/PIVX (Newest First)
- This adds the necessary GUI elements and backend connections for Cold Staking functionality into the next generation GUI included in 4.0.
- This is a major step forward in improving the current Proof of Stake performance in order to enable more consistent & predictable block times.
- This improves the Multisend handling during staking when UTXO that won the block reward is split, thus preventing multiple transfers during that occurrence.
- This fixes and thus prevents very large free transactions being accepted into blocks, despite what the block creator sets the -blockminsize parameter to.
- This pull request is a happy melting pot of improvements regarding transactions handling with most being backports from bitcoin.
- So far, there are more than 10 improvements included in this PR and the full list can be found in the initial PR notes.
- This enhancement will make the staking inputs split into 2 or more outputs based on the stake split threshold instead of splitting in half.
- This is a highly requested feature where it provides users an option to backup and restore the entire wallet (all associated addresses and their balances) using a multi-word seed phrase instead of more complex file-based or private-key methods.
- This customized staking feature (name subject to change) allows a mutually agreed full-node online wallet to stake coins from an address that it has been given delegation to stake from. This provides extra security for stakers while still requiring a full node online wallet. More info can be found HERE
- This is a brand new UI/UX wallet, designed in collaboration with Krubit UI and UX designers and written from scratch in Qt by core dev furszy and Krubit front-end developers. More info and a full demo video can be seen HERE
- Public testnet release of the next generation wallet GUI has been released in the latest segregated testnet release.
- This enhances the AutoCombineRewards function allowing the user to configure how often to run the scan, and the amount to combine each time it executes; as well as adding a new One Shot option that enables sweep on next block, and at wallet startup.
- This advanced function will allow spending of legacy zPIV v1 (minted prior to 3.1 release) back to PIV.
Major Development Targets
