Focus
The technological focus for EWC is decided in the Consortium Focus Sessions which happen every 3-4 months.
Our specs for the next 3 months:
- OIDC4VI: https://openid.net/specs/openid-4-verifiable-credential-issuance-1_0.html
- OIDC4VP: https://openid.net/specs/openid-connect-4-verifiable-presentations-1_0-07.html
- SD-JWT: https://datatracker.ietf.org/doc/draft-ietf-oauth-selective-disclosure-jwt/ (unless you’re doing mDL)
On SD-JWT we recommend looking at HAIP: https://vcstuff.github.io/oid4vc-haip-sd-jwt-vc/draft-oid4vc-haip-sd-jwt-vc.html
HAIP includes some additional specifications:
- OpenID for Verifiable Credential Issuance
- OpenID for Verifiable Presentations
- SIOPv2
- SD-JWT VC In turn, SD-JWT VC includes the SD- JWT specification and references the JWT CWT status list specification. If you want SD-JWT support for your attestations and want it to work with OpenID4VC, then HAIP is the most mature specification we have to date. There is some work that remains to be done, and the HAIP lacks some stuff (like support for OIDC federations), but these are minor things that we can add separately if we need it.
