 :::note Important Distinction
-The registry is a publication mechanism, not a VCTM resolution service. VCTM resolution (looking up credential type metadata by VCT identifier) is implemented separately. See the [go-wallet-backend](https://github.com/sirosfoundation/go-wallet-backend) for a reference implementation that can use registry.siros.org as a backend.

 ## What is VCTM?
 
 Verifiable Credential Type Metadata (VCTM) files define how credentials should be displayed and what claims they contain. They follow the [IETF SD-JWT VC specification](https://datatracker.ietf.org/doc/draft-ietf-oauth-sd-jwt-vc/).
