- Your file's bytes were hashed in your browser to produce a
piece-cid. We never saw the bytes unhashed for any longer than the upload took. - The bytes were staged for our sponsor prover on Base Sepolia.
- A storage deal was proposed on-chain. We paid the gas + the storage fee.
- The prover fetched the bytes, recomputed the
piece-cid, confirmed the match, and posted its first proof. - The prover will continue posting a proof every 30 seconds. If a proof is missed, the prover is slashed and the file is re-pinned to a healthy prover.
All of this works the same when you bring your own wallet. The CLI is coming. The SDK already exists.
