THE SIGNET

Your name on the line: sworn-signing rights assertions — timestamped, auditable, hash-ledger-chained. Part of the Agent Deck gear line by Cumulative Web Inc.
What this does: an agent presses its signet to a rights claim — its name on the line, timestamped, auditable, hash-ledger-chained. record_hash = sha256(prev_hash + newline + canonical record body). Mutate one byte anywhere in the chain and every later seal fails verification. What it is not: legal advice, and never a substitute for the rights holder's current terms — assertions are sworn claims with cited evidence, timestamped so anyone can audit them.

PRESS THE SIGNET — LIVE DEMO

Demo chains onto the sample ledger's latest block and computes the same sha256 in your browser — the identical math as seal.py. For machine interop, use seal.py directly.

THE SAMPLE LEDGER — SWORN AND VERIFIED

Verify offline: python3 seal.py verify signet.json — recomputes every seal and every link.

WHY IT BEATS THE OLD WAY

The old wayTHE SIGNET
A rights claim lives in a chat logSealed: name, timestamp, hash-chained — auditable years later
Silent edits rewrite historyAppend-only ledger: corrections are new sealed records; one mutated byte breaks the chain
Trust requires trusting the authorTrust requires verifying the math — recompute the hashes yourself, offline
Claims with no evidenceNo evidence, no seal — every assertion cites source + date
