Interoperability
Open standards, not an island.
We do not invent a format of our own. ProofLayer builds entirely on the standards the EU is aligning its digital identity around — so your credentials stay verifiable even if ProofLayer is no longer in the picture.
OID4VCI
Issuing credentials into any compatible wallet.
OID4VP
Presentation and verification straight from the holder's wallet.
SD-JWT VC
Primary format — signed and selectively disclosable.
W3C VC
Interoperability layer for exchange with third parties.
Status List
Standardised revocation and suspension checks.
DIDs
Decentralised identifiers for issuers and institutions.
Trust domains
Two routes to being trusted.
In production · did:hedera
Self-sovereign domain
Your own trust registry, your own anchor. No gatekeeper, no accreditation required — for closed ecosystems and markets outside the EU framework. In use today with education providers in Africa, where credential fraud is an acute problem.
In progress · did:ebsi / EUDI
European domain
Accreditation along the Root TAO → TAO → Trusted Issuer chain, embedded in eIDAS 2.0, connecting to European Digital Credentials for Learning. The right route for European universities.
With did:hedera you own the trust anchor. With did:ebsi you are accredited into someone else's trust. The choice follows the target market, not the technology.
Trust is not claimed.
It is calculated.
Let us take one degree programme and show you. Four to six weeks, on the test network, with no production data.
