Zcash Z3 updates (formerly Zcashd Deprecation)

Ecosystem Updates
98

July 18th

Hello! After some intense days of travelling, meetups and talks, the teams are fully back to Z3. We’ve made a few changes in our weekly syncs, also I’ll be collaborating with ECC, ZF and Zaino to improve visibility of our progress. This is easier said than done since we will have to reconcile different tools into one dashboard of graphic aid that let’s everyone know how we are doing.

Outreach

Status: resumed
ZCG members and myself regroup to brainstorm about how to improve our engagement rate in the face of the Zallet Alpha phase. We’ve come up with a new approach for the outreach and we will pivot to it next week.

Zebra

Project Roadmap board
Priority board

A stumble is not a fall! The Zebra team informed that they’ve removed Zebra 2.4.0 due to a regression. Still progress continues with the inclusion of a functionality that lets Zaino and other clients know what changed in the mempool. Zaino folks cheered at this piece of news. Mine to Orchard is also progressing along with a lot of silent work that Alfredo is doing with the RPC tests that will verify functionality that exists on Zcashd and that should exist in Zebrad. Zebra is also getting overhauled with performance optimizations like orchard batch processing.

Zaino (ZingoLabs)

  • Status: in progress

Project Board

Zaino folks are doing a bunch of things at once. On block explorer support a few RPCs are in development

Integration with the latest Zebra code has been kind of problematic and the teams are trying to figure out what is the process that can avoid these integration problems that deviate focus from development.

Zaino API meetings continue to happen weekly and Zaino re-architecture keeps progressing.

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

Kris Nuttycombe will try to make some room on his schedule to complete this review.

Zallet full node wallet

  • Status: in progress

tracking work on this repository.

Zallet keeps progressing towards its MVP or Alpha phase Str4d added support for data-dir which will surely help folks testing different wallets.

We are still looking for testers and new developers. See the call to action below

Call for Testers!

This won’t be a public alpha. We are looking for people that can build Zallet from code and run it with their Zebra nodes.

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!.

Block Explorer Support

  • Status: Testing

Specifically on Block Explorer support another small change that fell through the cracks in development [#9427] Fix: possibly change “lockbox” vs “deferred” value pool name

Pending reviews:

Regtest? What is that?

  • Status: in review

I’ve addressed a second round of comments and am waiting for more.

Thanks for reading!
