BLOCKCHAIN LAB BRIEFING · KYB AND IDENTITY
A Verifiable Credential Stays with the Holder. The Ledger Stores a Reference, If Anything.
The W3C verifiable-credentials model lets a verifier check a signed claim. It is not a proposal to publish the claim on a public network.
2 October 2026
01
What happened
The W3C data model defines issuers, holders and verifiers. The holder presents a credential. The verifier checks the signature and a status list. The core model does not require the contents to be written to a global ledger.
An anchor for a key is still not a passport.
02
Why it matters
TrustOps refuses to put the file on-chain. A credential is a format that fits that refusal: the verifier gets a proof, the desk keeps the file, and revocation can be checked without republishing the person.
An access token gated by a credential is an access rule. It is not an identity.
03
The operating layer
Issue to the holder. Publish a status list you can update. If a contract must gate something, store pass or fail and a policy id. Do not store the legal name.
A credential that cannot be revoked is a badge, not a control.
04
What is verified
Verifiable Credentials Data Model 2.0 is a W3C recommendation. This page does not say a given credential satisfies a national KYB rule.
05
What remains unclear
Which claims a regulator will accept without the underlying file. Who can suppress the status list.
06
The catch
The useful move is selective disclosure and a status check. The file stays where it can be deleted.
Not a vendor endorsement.
WATCH
What builders should watch
- 01The claims inside the credential.
- 02Where revocation lives.
- 03What the chain stores: a result, not the document.
BOTTOM LINE
Present a proof. Do not publish the person.
Sources
Blockchain Lab uses public social posts as reporting leads, not as proof. Every published briefing is assessed against primary sources, available documentation and relevant technical context. Social engagement is not used as evidence of the underlying claim.
