Provenance Vault

Immutable Ledger

Write once, alter never.

The Immutable Ledger records every decision in a write-once, tamper-evident history. Each entry is hashed and chained to the one before it, so records cannot be altered, deleted or reordered without detection.

Tamper-evident by construction

Every decision is hashed and linked to its predecessor. Changing any earlier record would break the chain, which makes silent edits detectable rather than possible.

A complete history

The ledger holds the full record of what was authorised, escalated or blocked, so the history of an agent's behaviour is always available to look back on.

Verifiable offline

Because records are signed and chained, they can be verified independently, without trusting the system that produced them.
