Outreach

Status: To be resumed
Pili and Pacu discussed starting an outreach targeting known “Node as a service” API providers to start providing Zebra instances.

Zebra

Zebra folks moved the Python QA framework into a new repo (see Zallet section for more details) and according to the last Arborist Call report they reached parity with Zcashd mempool features. Also worked on peer connection metrics fixes, enhancements on ReadStateService, Regtest mode and CI improvements.

Zaino (ZingoLabs)

  • Status: next release 0.2.0

Project Board

Zingoistas are preparing Zaino 0.2.0 and their current release candidate is RC4. The Dev team is taking care of some issues blocking the official release. Meanwhile Zebra 4 support changes will be queued after the release comes out, which is more important to finish this first release process which the Zaino team is also “releasing”. Zaino developers also asked Zallet devs to review their subtreeroots branch, a requirement that is currently blocking Zallet folks from integrating Zaino’s state service which uses Zebra’s ReadStateService backend instead of RPC’s.

Zallet full node wallet

  • Status: working towards alpha.4

tracking work on this repository and collaboration opportunities tracked on this board.

Zallet folks keep progressing on Zallet on z_shieldcoinbase on the backend stack (Coinbase maturity) and integration of P2SH support to import Zcashd wallets which use those keys. Str4d (in collaboration with Alfredo) factored out integration tests from Zebra and Zcash and built an integrated stack with Zebra, Zaino and Zallet that exercises a full test suite of integration tests over the RPC surface. You can find the integration test repo here

Block Explorer Support

  • Status: Coming soon!

Tracking: https://github.com/orgs/zingolabs/projects/15

This has been paused in order to wrap up chain_state work first. Otherwise these RPCs will have to be reworked with the new chain_state changes.
