Who Can Check a Tokenized Record?

Access to data is not the same as access to evidence

For decades, working with MBS data has required specialized tools and teams. Pool-level figures are published by each agency's disclosure platform, and the work of collecting, comparing and correcting them happens inside the systems of dealers, custodians and analytics providers. Each institution reaches its own conclusion, and the evidence behind it stays inside that institution.

Putting a number onchain does not change that by itself. A figure posted by a single publisher is still a claim that has to be taken on trust. Onchain, that trust usually gets delivered as a number with no proof attached.

What an independent check requires

An attestation is an independent confirmation that a specific piece of data was accurate at a specific moment, recorded so that anyone can check it afterward without relying on the party that published it. For that to be true in practice, three things need to hold.

• The record has to be signed. A cryptographic signature ties the record to the attestor and shows it has not changed since.
• The record has to be durable. It stays checkable long after the moment it describes, not only while everyone is watching.
• The verifier has to be separate from the publisher. If the only way to check a record is to ask the system that produced it, the check is not independent.

Who needs to check

Anyone whose decisions, products or settlements depend on data being right has a use for a record that can be checked. Tokenized markets raise familiar questions from risk, audit and compliance teams. Where did this figure come from? What happened when two sources disagreed? Can we show it a year from now?

• Counterparties need to know the value they settled at was based on validated data.
• Auditors need an audit trail they can read without relying on the firm being audited.
• Regulators need to see what was known, from which sources, at what moment.
• Platforms need inputs they can defend if a settlement is questioned.

You do not need to be an OWNR customer to check an OWNR record. The verification tool is separate from the publisher, so any party can confirm a signature and read the audit trail on their own.

How verification works in the pilot

In OWNR's agency MBS pilot, each validated claim is signed and written as a timestamped onchain record. A separate verification interface, run apart from the publisher, confirms any record. When a third party checks a record, the verifier confirms the signature and audit trail without relying on OWNR's live system.
