TAO -> Trusted Issuer (TI)
Verifiable Accreditations from a TAO to a Trusted Issuer.
A Trusted Accreditation Organisation (TAO) can delegate authority to Trusted Issuers (TIs) by issuing them Verifiable Accreditations. These accreditations grant permission to issue specific types of Verifiable Attestations â such as diplomas, licences, or professional credentials â within the boundaries of a defined governance framework.
The Verifiable Accreditation should include:
Issuer
DID of the TAO
did:cheqd:testnet:e66a9416-d03e-4ced-95e3-07af16e25bc5
Subject
DID of the Trusted Issuer that is being accredited
did:cheqd:testnet:f6e731f0-5bfb-429b-b2c7-e65a951d7b5e
Credential Subject
A set of structured permissions around what credentials the Trusted Issuer is accredited to issue, and in which jurisdiction.

Terms of use
A set of policies setting out the scope of Trust Chain for Relying parties to validate against.

Root TAOs can set permissions under which TAOs must abide. This creates a level of codified governance for the trust ecosystem.

For all Verifiable Accreditations, the accreditations are stored as DID-Linked Resources (DLRs), linked to the DID of the Accreditor. This means that the Accreditations are publically available, fully DID resolvable and are signed by the authentication
keys within the DID Document of the Accreditor.
