Data Availability Solutions on Tezos
summary
Demonstrates two concrete data-availability paths for Tezos rollups: a deployed DAC demo: send payload get certificate where a 5 KB test payload (demo also shows handling 2 MB) is posted to committee members, two signatures return a small certificate that the rollup injects and the rollup node fetches and displays; and a planned DAL using erasure coding into shards, a commitment ~50 bytes stored on L1, baker attestations needing roughly 30–60% honest bakers today and a 10 MB target bandwidth goal for slots, with DAL on testnets and mainnet aimed for 2024.
