This development update is an attempt to summarize all the core development work that is going on in the GitHub for the period covered (usually 2 weeks). This should show the vast amount of work of our developers that many may not realize is happening each and every day. Do note that this doesn’t just cover the work by the PIVX core developers but will also highlight all community / open developers that contribute to the code base. If you think you can help out either as a hobby or full time, jump right in! It’s open source after all. 😉
PIVX Development Update
Week 1, October 2019
This update covers the development between the last update back in end of August, up to October 1 (approx. 5 weeks) and as expected, a ton of work has been done during this time. Our development activity is higher than it’s ever been, and upcoming 4.0 wallet is shaping up to be one of our most solid upgrades to date!
Core wallet v3.4 Release Update
- 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.
- Successful hard fork occurred at block 1967000 on August 31 2019 with majority of major exchanges confirming the upgrade. If you are using a previous version, make sure you upgrade and check that you are on the right chain.
- 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.
Next generation 4.0 UI Merged
“After 7 long months, a lot of planning, coding and reviewing, I’m really happy to announce that we just merged my #954 PR!” – furszy
What this means is that the new UI will be included in the next major wallet release!
The work included:
- 428 files changed
- 373 commits involved
- 50,844 lines of code added.
It was designed and coded from the ground up with unique code on top of the QT framework. So it’s brand new just for PIVX! Watch the developer’s demo video.
Cold Staking now in Testing
Cold Staking (PR #955) is being put through its paces in a segregated testnet maintained by the core developers and we are hearing reports that it’s running very smoothly along with some block explorer proofs! This new upcoming functionality will allow a more secure way to stake PIVX without the need for having the coins on a hot (online) wallet.
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 some awesome contributions by our community developers and this activity can now be tracked on our new Community Developer Contributions Project page within the PIVX GitHub!
PIVXPress is back with a new host!
Long time PIVX member Jeffrey is now the new host for PIVXPress video updates. Expect some great lively updates including development news from the new series.
Complete GitHub Activity
(September 1, 2019 – October 1, 2019)
7 developers have pushed 217 commits to master and 358 commits to all branches. On master, 563 files have changed and there have been 60,391 additions and 24,852 deletions!

(there are tons more that I haven’t highlighted here, so always check the GitHub if you want to see a full picture of what is going on)
- This advanced function will allow spending of legacy zPIV v1 (minted prior to 3.1 release) back to PIV.
- 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 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.
- 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 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 enhancement will make the staking inputs split into 2 or more outputs based on the stake split threshold instead of splitting in half.
- 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 fixes and thus prevents very large free transactions being accepted into blocks, despite what the block creator sets the -blockminsize parameter to.
- This improves the Multisend handling during staking when UTXO that won the block reward is split, thus preventing multiple transfers during that occurrence.
- This is a major step forward in improving the current Proof of Stake performance in order to enable more consistent & predictable block times.
- This adds the necessary GUI elements and backend connections for Cold Staking functionality into the next generation GUI included in 4.0.
It’s been over a month since the last update (my apologies!) and means that this update ended up being massive once again! The sheer amount of work, both quantity and quality, by our PIVX developers is simply astounding with the number of unique commits by PIVX developers within the year exceeds much larger cryptocurrencies such as even Ethereum, Cardano, Monero, DASH, and Zcash etc! (ref. CryptoMiso) That’s some serious commitment! (pun not intended)
Also, we are not just talking about minor commits here. PIVX developers has been working very hard to make significant improvements to the PIVX core, as well as only adding new features & functionality that will improve usability, security, and stability of the PIVX wallet / blockchain..
PIVX is in great hands with world class development ongoing. Not a doubt in my mind. – jakiman
On a separate non-core development front, PIVX core developer furszy has been doing some serious parallel work and has recently announced a new decentralized multi-wallet and point of sale app called Exobit on the Android platform. Testnet version is now available and it is planned to include atomic swaps (essentially DEX) later on with PIVX being the first alt-coin to be listed alongside Bitcoin. So keep an eye out on the development progress as it could be an important first-party app for PIVX! More info plus an intro video can be seen here.
