Outreach

Status: Paused :white_check_mark:
We wrapped up the Zcashd EOS outreach successfully. Awaiting for Zallet Alpha 4 to be released to resume any outreach efforts.

Zebra

ZF engineers finished integrating OpenRPC and RPC discovery endpoint. Also worked on Prometheus observability metrics, got gettxout RPC that was requested by and handful of partners who relied on it. Also got getrawtransaction in parity with Zcashd. There’s “one more thing” which is shielded coinbase support which is currently blocked on a zcash_script dependency that needs to be updated and ZODL and ZF engineers are working on addressing. Once we have shielded coinbase Zaino folks will be able to lower their testing times significantly.

Zaino (ZingoLabs)

  • Status: in progress

Project Board

Zaino is about to cut a release! But before that happens we need a few things to be ironed out, like the Zebra 4.1.0 support PR which has one test failing on CI but not locally so we are investigating what’s going on there to avoid regression. Zaino `dev` now supports passthrough which enables Zaino to forward requests to the backing validator when syncing. Local_cache has been deprecated and the chain index work is around the corner. Once we have that in place the remaining RPCs from the block explorer section can be tackled.

Zallet full node wallet

  • Status: new alpha incoming! :white_check_mark:

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

Zallet developers are working on several RPCs and also put a lot of effort into newly integration tests crates from Str4d and Alfredo. Contributors can use this framework to test their code.

Additionally, a bunch of community contributions were received and are being reviewed. I’m grooming the board to get more tasks to our eager contributors.Keep them coming!

Block Explorer Support

  • Status: Paused

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.
