Complete Zaino!

Unanimous approval.

Zingo Labs is requesting $151,240 to upgrade and extend Zcash infrastructure through the Zaino project. Focusing on decentralizing critical components by implementing core functionality and APIs in Rust. The project aims to replace an outdated c++ component with modern Rust technology, improving development speed and efficiency while collaborating with ECC, ZF, Blockchain Commons and others. The grant is going to cover hardware, software services, and compensation for developers who are working full-time over a three month period. The milestones include the implementation of new RPCs, updating the Zcash RPC specification, and integrating a back end to support light wallets. ZCG members are asked to provide their feedback and vote. Artkor: I support moving forward with this grant. I approve. Brian: I definitely support this grant. I think it’s important and would like to see this team continue to be funded and engaged. Zerodartz: I also agree. Zaino has become part of the core protocol and it’s important they can make it on time and so far they’ve delivered pretty well. I approve. Jason: Zingo is doing a great job. I hear a lot of positive feedback about their contribution to the zcashd depreciation effort. Their collaboration with Blockchain Commons is also very much valued by the core teams. I approve.

Zingo Labs is requesting $151,240 to upgrade and extend Zcash infrastructure through the Zaino project. Focusing on decentralizing critical components by implementing core functionality and APIs in Rust. The project aims to replace an outdated c++ component with modern Rust technology, improving development speed and efficiency while collaborating with ECC, ZF, Blockchain Commons and others.

The milestones include the implementation of new RPCs, updating the Zcash RPC specification, and integrating a back end to support light wallets. So, I guess one question that came up when we talked about this on Friday, is that we want to understand how the original Zaino grant didn’t encompass this work. We need to determine if this is an issue with delays or if it’s unexpected work that came up, or if this is a different part of the project. Wobzz has reached out to Zancas with these questions. Jason: We’re going to wait to see what Zancas’ response is to Brian’s message and we’re going to bring this up for discussion at the Arborist Call this week. There’s talk about further delays for Zcashd deprecation and Nu7 and we now have three teams that are doing ongoing work related to this: Zingo, Blockchain Commons, and Qedit. We don’t want to be in a position where we have these ongoing funding obligations that are open-ended. Thoughts? Artkor: I agree. I appreciate the work done so far and the value Zingo brings to the ecosystem, but before we move forward this, these requests we need some clarity. Why weren’t these milestones part of the original grant? I support holding off on further discussion until we have our questions answered.
