June 13th
It’s Friday the 13th! Well… for some folks that doesn’t mean anything. Did you know that for different cultures it’s other days on the calendar that are “jinxed”? In Spanish culture it’s Tuesday the 13th. “Martes 13 no te cases ni te embarques” my grandma used to say. For my Italian part of the family it was Friday the 17th. The number 17th is “La disgrazia” of italian culture.
Ignoring all superstitions I embarked myself! Because I believe in science, probability and moon math. Next week I’m going to be taking a few days off, so the June 20th update will probably not be published as thoroughly or at all.
In terms of our Z3 endeavor and last week’s update, Z3 workgroups have started and advancements have been made.
I would like to specially thank @nuttycom for helping out in various matters and for making time on this busy schedule for myself and ZCG.
Outreach
Status: Paused
We will discuss this further in the next sections but we are getting closer to having 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
The Zebra team has completed another Sprint! And of course, @pili has written an awesome engineering update. You should go read it and leave comments to this great engineering team we have in our Ecosystem. There has been a lot of progress around Block Explorer support, mining to shielded pools and RPC tests with Zallet. Go Zebra!

Zallet full node wallet

ECC has notified a deviation of 2 months from the original schedule.
tracking work on this repository.
Kris and Str4d continue to work on Zallet with enhancements on sync, importing Zcashd wallet.dat files and also pairing with Zaino folks on API requirements for Zaino, data that Zallet needs available and performance expectation for each kind of data indexed by Zingo’s winning horse. ECC core devs are also figuring out the outstanding pieces for an Alpha version of Zallet. Listen the announcement on the June 12th Arborist Call
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: in progress
I started to get into the nitty-gritty of Zcash Block explorer support which led to opening some issues to the Zebra repository to add missing data in Zebra’s transaction data object which is what different zebra clients consume and that the block explorer needs when showing a block details and transaction details. I humbly sent a pull request to add one of the needed fields and reviews did not wait to come.

Regtest? What is that?
- Status: in review
I’ve addressed a second round of comments and am waiting for more.
Thanks for reading!
