Tomorrow Ironwood brings: - Formally verified shielded pool - Quantum recoverability - Privacy-preserving pool deprecation & migration logic The third is actually where all the work for this upgrade has gone. We want you to be able to migrate while preventing anyone from learning your exact balance, or linking your deposits. At a glance: - We must freeze Orchard, while allowing withdraws and splitting up your own txs - Turns out no shielded pool considered allowing private fund-splitting in withdraw only mode! - This is the circuit update - Orchard ZKP's are "per action" not "per tx". So we must prove - We must make it possible to pre-sign all your txs. - It was news to me this was not possible prior to this upgrade. RIP multisigs. Now it is :) - We must make your hardware wallets capable of pre-signing ~100 txs. Would have taken hours before. Now minutes. - Make your wallets able to produce dozens of ZKP's in the background. This involves fighting the limits of background wallet syncing and background compute The wallet stack has had large rewrites to facilitate this, shoutout to everyone involved! And that doesn't even include all the parallel work in scale and making the p2p stack more connected, and secure!
