Outreach

Status: resumed :white_check_mark:

As you might have heard, Zcashd maintainers received a responsible disclosure of an issue in sprout. After Shielded Labs and ZODL devs wrapped up their response procedure and released Zcashd 6.13.0 I quickly ran through our contact master list and messaged the rest of the organizations so they updated ASAP to the new version.

Zebra

ZF folks worked on adding ZIP 235 to Zebra, fixes on regtest mode and getblocksubsidy RPC. They are also working on sync improvements on testnet that will later translate to Mainnet. I had the chance to try that code locally and on a clunky cheap server I have and the improvements on testnet were incredible. Congratulations!

Zaino (ZingoLabs)

  • Status: released 0.2.0

Project Board

Zaino is working hand in hand with Zallet and also with light wallets. Zingo folks wrapped up Zebra 4.3.0 support and fixes on get_block_range lightclient RPCs that solved issues with ZODL wallet. Lots of progress is being made.

Zallet full node wallet

  • Status: working towards alpha.4

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

ZODL engineers reported having improved integration to Zaino’s chain-index service to a great extent and syncing full blocks. They are also getting P2SH import for Zcashd migration and also working on ancient regtest wallets to then test the wallet migration path with curious wallet schemes and not just happy paths.

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.
