Forensic replay

Audit chain verifier.

Replay your ledger. Confirm every SHA-256 chain link. Surface tampered rows the moment they exist. Works online with an API key, or air-gapped against exported JSON.

How verification works. Each audit entry stores a proof hash and a reference to the previous block's hash inside its evidence array. We walk the chain from newest to oldest; any broken link fails the whole audit. No trust, just cryptography.

Chain health

Sequential SHA-256

Every proof links to the previous block.

Verification modes

Online + offline

API key fetch or local JSON audit.

Forensic posture

Tamper evident

Broken links surface immediately.

Failure mode

Fail-closed

One bad link invalidates the run.

Paste your API key. The verifier hits GET /v1/audit under your auth, then walks the chain locally in your browser. Your key never leaves this page.
