Check it yourself

  1. Read the claim as JSON at /api/delivery/56614. The field claim is the statement, hash its sha256.
  2. Rebuild the canonical text: the claim with its keys in this order and no whitespace, a missing field as null: v, job, chainId, provider, buyer, status, verdict, deliverable, onChain, permanentCopy, hired, deliveredInSeconds, settled, checks, checkedAt. Its sha256 must equal hash.
  3. Open the opBNB transaction 0x82d57d8c...033524. Its data ends with that hash and carries the claim number; the sender is 0x7f8d2C80f34a1A85bAb3FDbAcBcFB2ebb5Cd6474, the ChainHelix delivery key, which signs nothing else.
  4. Fetch the deliverable yourself and hash the bytes. sha256 must equal the value above, keccak256 must equal the pointer on chain.
