Flight Recorder · Live

Prove what your system did — to anyone, without trust.

Engine ready

Every button below runs the real Flight Recorder engine: it turns a stream of decisions into an append-only, hash-chained log with Merkle inclusion and consistency proofs. Any third party can audit one entry, or confirm the log was never rewritten, without reading the whole log and without trusting the operator. Tamper is detected, never tolerated. Pure logic; no keys, no network, nothing broadcast.

The audit guarantees, end to end

A fresh hash-chained log of audit records — agent decisions, compliance checks, settlement steps. Each button drives a different real operation on this log: the engine, not this page, computes every proof and verdict.

Log FAS-FR · Flight Recorder · append-only Merkle log · each entry commits to its predecessor · root evolves on every append.
Inclusion proves a single entry is committed in the published root in O(log n). Consistency proves the log was only ever appended — no deletion, no reorder. Tamper flips one byte in a valid proof; the verifier rejects it. Anchor builds an unsigned on-chain transaction carrying the root — the operator signs and submits; Flight Recorder never holds keys.
