The identity layer.
For receipts that prove who.
OIDC tokens, verifiable presentations via OID4VP, FROST co-signing for closing keypairs. Every other pillar starts here.
Two ways in
One scenario. One artifact.
A buyer presents an employment credential.
Sarah holds a verifiable credential issued by her employer. She presents it to the lender via OID4VP. The lender verifies it without calling HR. The whole exchange spends 0.6 joules and emits a signed receipt.
Identity standards, side by side.
OIDC · OID4VC · OID4VP · DIF Presentation Exchange · FROST. Pick a standard, see the receipt it produces, hover any field for the RFC it cites.
The receipt
Every operation. Every joule. Signed.
This is what TrustOS returns. Not just a result — a signed JWP ReceiptPayload with the energy consumed, the standard cited, and the cryptographic signature that makes it audit-grade.
