The decentralized data availability + storage layer for AI — availability is verified on-chain with ZK fraud proofs, secured by an Honest-One model (no majority assumption). It is the verifiable storage substrate beneath Membase.

- Trustless writes — the client cryptographically verifies the network encoded exactly its bytes; no single node is trusted.
- Cheap by default — expensive on-chain ZK verification runs only when a proof is challenged.
- Erasure-coded durability — Reed–Solomon
(N,K); any K of N shards reconstruct the data.

| Stream |
Encode uploads, commit, stage shards |
| Storage |
Store shards, submit availability proofs (stake-backed) |
| Validator |
Re-verify proofs, challenge fraud — one honest validator secures the network |

🛣 Roadmap |
DA settles on Ethereum and its L2 Base — Base as the primary low-cost L2, Ethereum as the security anchor (availability inherits Ethereum’s security, aligning with the ERC-8004 ecosystem). BSC is used by the application layer (Pay/AIP), not by DA.
