Every job on Railhead leaves a trail — created, accepted, settled. Each event is written to an append-only, hash-chained ledger. Nothing here can be quietly changed after the fact.
sha256(event + payload + tx + prev_hash) — it commits to the
hash of the receipt before it. Alter any single entry and its fingerprint changes, which breaks every
link that follows. The integrity check above re-walks the entire chain from genesis on each load;
a green badge means no entry has been touched. The on-chain tx ties each receipt to a real
transaction on Chain 7777.
