Dev Update August

Feb 2, 2020PIVX Development Update – Week 4, January 2020

(Apologies for posting it a day late…) This update covers the PIVX GitHub development for the past 1 month of January 2020 (+ a bit of December 2019) in addition to any extra update provided by the core development team.

Editor Comments

The month of January 2020 (and December 2019) has been another huge month/s for PIVX with some major milestones being hit. For example, a major 4.0 core wallet was released in December 2019 and this wallet included the long awaited brand new Qt GUI change, more secure Cold Staking, and the new PoS Time v2 protocol just to name a few! 

A successful hard fork occurred on Sunday, January 5, 2020 12AM GMT at Block 2,153,200 and this led to more consistent block times thanks to the updated PoS Time v2 protocol. 

Now that this is done and settled, we are now moving onto the next major phase in PIVX. Yes, it’s finally time for the developers to focus on a new privacy protocol for PIVX to replace the deprecated zerocoin protocol. Research has already been underway, and soon the plan will be disclosed publicly that will include what protocol will be integrated into PIVX, why it was chosen, and why our particular implementation would be more unique. From what little has been said about it so far, what I know is that it will be a significantly better protocol than Zerocoin in every way possible! Expect it to be revealed sometime in February.

We all know that we have developers that can talk the talk, and walk the walk. We also know that we have a hard working team that has been passionate since 2016, and the numbers have also have grown this year with more joining and volunteering.

So all in all, I just cannot stress enough on how exciting time this is, and how big this year will be for PIVX as a result of what is planned to happen this year! (Not financial advice! =p)

Check out what Jeffrey has to say about our recent development activity!

Development Highlights

Cold Staking is now Active!

Cold Staking (PR #955) is now active in mainnet so all users are now able to cold stake their coins if the required steps have been executed. We have created a basic how-to guide here. Also, some non-custodial (thus safe) cold staking services have started popping up so that is another option if you feel comfortable with their service levels.

New PoS Time protocol v2 now enabled

A more robust Proof of Stake protocol for PIVX (PR #1002) has also been activated in the network that includes a host of improvements including difficulty algorithm changes, and removal of legacy PoW code engagement. What this means is that we now have more consistent block times, more secure network, less energy consumption, more low-end device friendly, and fairer block reward distribution. 

New Wallet Releases – 4.0.2 Latest 

Wallet version 4.0.1 was released shortly after 4.0.0 to address some zero day bugs, then version 4.0.2 was released on January 14th with some additional fixes and enhancements. As of this writing, 4.0.2 is the latest version of the core wallet. Note: If you are still running 3.x wallet, you must update to the 4.0.2 wallet and ensure you are in sync with the blockchain as the old wallet is no longer compatible with the new wallet’s chain.

All Zerocoins are now spendable!

PublicCoinSpend v4 (PR #936) function has been incorporated into 4.x wallet and so it is now possible for anyone with any version of zPIV (v1 or v2) to spend them back as PIV. We encourage everyone to convert their zPIV into PIV. (Wiki)

Upcoming PR Highlights

This section may not include all highlight-able PRs)

PR #956 – [Core][Qt] Add HD Wallet support – submitted by community developer akshaynexus is being actively reviewed / worked on. 

  • This is a highly requested & much needed feature where it provides users an option to backup and restore the entire wallet (all associated addresses and their balances) using a single seed phrase instead of more complex file-based or private-key backup methods.
