ZSAs and Swaps--A Status Report

on YouTube ↗39m

" summary

QEDIT reports the Zcash Shielded Assets protocol as functionally ready with ZIP 226/227/230 drafted and a swaps spec as ZIP 228, circuit optimizations cut the Orchard-derived circuit rows from ~2207 down below the 2^11 limit, and note size grows from 564 to ZSA note 596 bytes (+32). Implementations touch orchard crate, zcash-note-encryption PR2, librustzcash, Zebra node support and a transaction test harness zcash-tx-tool; a V6 testnet on AWS runs and audits are being lined up.
