Outreach

We will discuss this further in the next sections but we are getting closer to have artifacts and containers that Zcash partners can start testing so we will pivot to the next phase of outreach when those are almost done.

Zebra

Project Roadmap board
Priority board

There’s a lot coming to completion in the Zebra house and that means a lot of code to review. Seventeen (yes 17) items are up for review and QA and from a variety of endeavors: Z3 stack, Zebra improvements, NU6.1 and NU7. But the Zebra folks are not only reading code but also writing and testing quite a lot of things with twelve items in progress. @oxabritrage is testing Zebra and Zallet integration and finding a lot of things to improve, Gustavo is working on containerization of the Z3 stack and that’s leading to important debate with all the team’s Infrastructure and DevOps specialists, Arya is literally EVERYWHERE and Marek is battling a long time foe: Orchard shielded coinbase which will help miners continue to moon the Orchard pool, but it will also speed up a lot of Zaino tests. woohoo!

Zaino (ZingoLabs)

  • Status: on track!

Project Board

As integration of the Z3 stacks progresses adjustments are made to Zingo’s winning horse Zaino. Like ​​better zebra error propagation. Work on refactoring how Zaino stores blockchain material is progressing as well. Draft PRs for Zcash Block Explorer support are starting to emerge! Every week we are 7 days closer to Zcashd deprecation and a lot of things are finally coming together!

In-Memory backend wrap up

- status: pending review :warning:

This has been falling through the cracks a bit, we still need to provide reviews to this PR https://github.com/zcash/librustzcash/pull/1634

We need reviewers for this!!

Zallet full node wallet

  • Status: delayed :warning: (but rapidly catching up)

ECC has notified a deviation of 2 months from the original schedule.

tracking work on this repository.

Zcashd wallet migration is one critical part of this all. And @nuttycom has done a tremendous effort to achieve this. A draft PR has been pushed! Add migrate_zcashd_wallet command.
Also a new RPC is seeing the light of day with the Add z_viewtransaction Pull Request from @str4d

Call for Developers!

If you want to start working on something Zcash related and you don’t know where to start, Zallet is a good way to do it. With many RPC methods already developed that can be good examples for the creation of others, the project is in a good shape to start taking contributions from the broad community. Fork the Zallet repo and start hacking!.

Wallet Export format + ZexCavator

  • Status: On-track

Zingo folks continue to work on ZexCavator. You are a week closer to dusting out that old wallet that you thought you’d never recover again! Also, next steps for ZeWIF ecosystem integration are being discussed and outlined by Blockchain Commons, core developers and ZCG.

Block Explorer Support

  • Status: in progress

This continues to be in development. We it happens that Coin Market Cap did need more that total supply, and we are working on that API method on the Zcash Block Explorer.

Regtest? What is that?

  • Status: paused

I haven’t been able to get to the second round of comments yet but it’s in my queue.

Thanks for reading!
