Data Availability

" summary

Avail launches a data-availability mainnet next month and claims its data availability sampling plus validity proofs let light clients verify huge rollup data cheaply. Avail Nexus is an L1.5 design with a RISC‑V prototype (message passing demonstrated between zkSync and Polygon zkEVM planned next quarter) that aggregates proofs and posts to Ethereum; Avail Fusion bootstraps economic security using BTC and ETH. Dencun / EIP‑4844 lowers blob costs but Avail targets thousands of app‑specific rollups.
