Proposal info:

This proposal will cover my development cost for the month of May. With respect to the last one (https://forum.pivx.org/threads/alessandro-pivx-dev-april.1323/) I am asking for 10k fewer PIVs since university exams are getting closer and so I will have less time to program. This month I will work mainly on the core wallet, in particular I will focus on: Deterministic Masternodes and Shield Staking.

Monthly update:

Web Shielding

The web shield library has been completed and published! (https://www.npmjs.com/package/pivx-shield) It has also been integrated by me and Duddino on MyPIVXWallet and it is waiting for the final reviews before getting merged (https://github.com/PIVX-Labs/MyPIVXWallet/pull/104), in particular MPW is the first web wallet (among all crypto) with Shield Support.
Apart for the all time spent on reviews I have contributed with 12 Pull Requests that can be found here (https://github.com/PIVX-Labs/pivx-shield/pulls?q=is:pr+author:panleone).


DMNs

Deterministic Masternodes are almost completed: The last update DIP8 (i.e. chainlocks) is working on my local branch (https://github.com/PIVX-Labs/PIVX/tree/2023_DMN_dip8) and I am waiting for DIP7 to get merged in order to open the pull request on the core wallet.

Shield Staking

I will work on Shield Staking with Duddino, it is something new that no crypto has yet, so we will need some time to do our research and implement an efficient algorithm and then probably have someone to audit it. I have already sketched a "raw" implementation but everything is still private and there is still tons of work to do.

Other updates:

I have also found and fixed some minor bugs/small improvements on the core wallet:
And an improvement on MyPivxWallet:


A possible roadmap:

DMNs

After merging chainlocks we will begin public testing the whole system on the testnet with a lot of masternodes to hopefully find the last bugs

Shield Staking

I still don't have a clear plan on this but a possible list of task is:
  • Create a shield staking algorithm
  • Implement an efficient zkproof that proves the correctness of your stake without revealing the stake
  • Implement all technical stuff about block creation with a shield stake (for example find a way to create the block signature, decide input and outputs of the shield stake tx, changes to consensus...)
  • Write functional and unit test

Yes! Sadly due to university exams I will have to quit development for the next month (That's why I did not publish another proposal)

Deterministic masternodes are at the same point as the last month, i.e. the last PR is still waiting for reviews https://github.com/PIVX-Project/PIVX/pull/2844

Shield staking has been implemented by me and Duddino and is working on regtest. https://github.com/PIVX-Project/PIVX/pull/2836
Duddino is now working on an optimization on the size of the proof (so shield staked blocks will be lighter). After that we will have to write unit and functional tests and wait for reviews.

Most of my time was spent on designing and implementing shield staking, however In addition to it I have also opened 7 PRs on core wallet the most important are:
Fix the invalidateblock rpc command https://github.com/PIVX-Project/PIVX/pull/2856
Possibility to send the change of a transaction to a sapling address using coin control https://github.com/PIVX-Project/PIVX/pull/2859
Possibility to lock sapling notes: https://github.com/PIVX-Project/PIVX/pull/2861
Possibility to create a masternode using coin control https://github.com/PIVX-Project/PIVX/pull/2862
