The unalterable record of everything your firm advises
Every AI-assisted advice interaction is recorded in a tamper-proof ledger. No one can change, delete, or backdate a record — not even Bedrock.
What is Bedrock Ledger?
Imagine a logbook where every entry is written in permanent ink, and each page contains a summary of the page before it. If someone tears out or alters a page, the summaries stop matching — and everyone can tell.
That's Bedrock Ledger, but digital and cryptographic. Every piece of advice your firm gives through AI is automatically recorded with a mathematical fingerprint linking it to everything that came before. The result is an audit trail that no one — including us — can tamper with.
What happens when advice is recorded
The advice is captured
Your AI system submits the advice document, client reference, and supporting data to Bedrock via API.
A fingerprint is calculated
Bedrock creates a unique mathematical fingerprint (SHA-256 hash) of the advice, combined with the fingerprint of the previous record in the chain.
The record is signed
An Ed25519 digital signature is applied to the record. This proves exactly when the record was created and that it hasn't been modified since.
The record is sealed
The signed record is written to immutable storage. From this moment, it cannot be changed or deleted by anyone — including Bedrock staff.
Why the chain matters
The chain is what makes the ledger tamper-proof. Each record depends on the one before it. Break one link and the entire chain fails verification.
Record 3 was altered. Records 4 and 5 now show mismatched fingerprints. The tampering is immediately and automatically detected.
Guarantees
Immutable
Records cannot be altered, deleted, or backdated once written. The ledger is append-only.
Hash-chained
Every record contains a fingerprint of the previous record, forming an unbreakable verification chain.
Digitally signed
Ed25519 signatures on every record prove authorship and integrity. Forgery is mathematically impossible.
Independently verifiable
Anyone with a certificate can verify it against the chain. No Bedrock account needed.
