Quick update on the last ~48 hours of Zcash Ironwood! 1. Protocol devs from across all the orgs met twice to discuss specification and implementation progress. Agreement on a couple additional changes: disabling Orchard pool bundles in coinbases, anchors as auth data for migration UX with hardware wallets, and the order that ZIPs and specs will be handled. 2. Ironwood circuit and ZIP 2005 integration drafts are going through the review process. @ValarGroup has already spun up testnets and his team has done a wonderful job scoping out and implementing some of the wallet-facing changes. We are beginning an Ironwood upgrade book for eventual consumption by auditors, wallets, protocol developers, etc.. 3. Formal verification work on Ironwood continues. A collection of different individuals who either have or will continue to work on formalization efforts will be meeting tomorrow where we'll settle on the specific strategy for getting the Ironwood SNARK formally verified. I'm hosting this and will post minutes and details after. Efforts from teams will be ideally combined where useful, existing approaches and progress unified and we'll figure out the easiest path for the next couple weeks. I've paused my own work on this to do Ironwood circuit stuff, but I'll be resuming on that tomorrow. These are the big pieces, there are also some major security auditing tasks taking place in the background -- at least three major firms are auditing Orchard currently, and multiple new AI auditing suites are hammering the codebases to ensure nothing else critical is sitting around anywhere. So far so good! Really proud of how much progress is being made every hour on this by all five of our major teams/orgs and our supporters inside and outside the community. Also love the general wartime vibe shift. Let's go!
