Professional Attestation Ledger · Patent P4

Every sign-off you make,
provable years later.

Credentialed professionals issue dozens of release decisions a week — opinions, clearances, sign-offs, safety releases. Today those sit in PDFs and vendor systems with editable timestamps. When a claim lands two years later, your defence rests on logs somebody else controls. This is the same idea as verified reviews, but the signer is you.

Chained to the previous entry

Any edit breaks the chain visibly

A signed release, chained to the one before it.

Across legal, medical, contracting, auto and financial work, professionals make release decisions constantly — and almost none of them are anchored to anything. Nothing survives an audit without a fight.

How it works today

Asserted by signature alone

Releases live in proprietary systems with editable timestamps and thin audit trails. When a malpractice claim, code dispute, recall investigation or regulator audit arrives two years later, your defence depends entirely on whatever your software vendor happened to log — and on everyone agreeing to trust that vendor.

How it works here

Credential-bound and chained

Each release is signed the moment you issue it, bound to your verified credential, and hash-linked to the previous entry in the ledger. The chain runs back to a genesis record, so any tampering breaks it visibly. Auditors, examiners and opposing counsel can verify it themselves — without trusting you, your software, or us.

What the ledger looks like.

A sample ledger across five industries. Every release signed by a credentialed professional, every one chained back to the entry before it, every one independently checkable.

Why this matters two years from now.

A defence that doesn’t depend on you

The strongest evidence is the kind you couldn’t have altered. A signed, chained release is exactly that — which is why it carries weight your own records never will.

Audits become queries

Licence renewals and board audits turn into a lookup instead of a document hunt. The compliance record was being built continuously the whole time.

It checks out independently

An examiner or opposing counsel verifies the chain themselves. Nobody has to take your word, your vendor’s word, or ours.

Own the record.

The same idea as verified reviews, applied to your professional judgement.
