Institutional-grade trust infrastructure

An immutable ledger for every verification

Once verified, a vendor's business, authorized representative, and bank account are locked to an immutable ledger. None of them can be changed without re-verifying through Coffr.

Coffr uses a third-party decentralized consensus layer to create continuously verifiable, tamper-evident trust records between business entities, enabling independent validation, stronger fraud protection, and complete auditability throughout the relationship lifecycle.

Locked as one record

Why the record matters

Databases are built to be edited. Proof shouldn't be.

Most payment and vendor systems store verified details in a database. Anyone with enough access can change them:

  • An admin
  • An attacker with stolen credentials
  • An insider
  • The software vendor

Logs can be edited too, so the change can leave no trace. A bank account gets swapped, and the original verification no longer means anything.

If your proof lives in a database, it's only as safe as everyone who can access it.

Recorded by consensus

Coffr writes proof to an immutable ledger

Coffr uses a third-party decentralized consensus network to record every verification.

No edits.3

A record can't be changed after it's written.

No deletes.3

A record can't be removed.

No single owner.

Independent organizations run the network. No one, including Coffr, controls it.

Consensus-verified.

A record is final only when the network agrees on it.

Locked once verified

Every change requires a new verification

After Coffr verifies a vendor, the business, the authorized representative, and the bank account are locked together as one record.

  • No edits.3
  • No overrides.
  • Every change requires a new Coffr verification.

A new bank account means a new verification, and that's written to the ledger too.

A tamper-proof audit chain

Past events stay exactly as written

Every verification event is added to an audit chain:

  • Who was verified
  • What was verified
  • When it happened, with the time set by the network, not by Coffr

Past events stay exactly as they were written. Your auditors get a complete, unbroken history they can check on their own.

Any change is caught

The fingerprint has to match

Each ledger record holds a cryptographic fingerprint of the verified details. If anyone changes those details anywhere, they no longer match the fingerprint. The change can't hide.

Your data stays private3

Only the fingerprint is written to the ledger. Names, bank account numbers, and tax IDs never are. The fingerprint can't be reversed to reveal them.

Frequently asked questions

Immutable ledger FAQ

It's distributed ledger technology (DLT). It keeps tamper-proof records like a blockchain does, with faster finality and no mining.

No. Once the network accepts a record, no one can change it, including Coffr.

The new account has to be verified through Coffr. That creates a new record on the ledger. The old record stays in the audit chain.

No. Only a cryptographic fingerprint goes on the ledger. Your data stays inside Coffr.

Your auditors, your counterparties, and any other authorized stakeholder can confirm a record matches its proof on the ledger.

Looking for the plain definition? Read What is an immutable ledger? in the Coffr glossary.

Verified once. Locked to the ledger. Changed only through Coffr.
