Abstract

The Hiero AnonCreds Method specification defines how AnonCreds objects should be registered (written) and resolved when rooting them in a Hedera DID. This specification parallels other DID-specific AnonCreds methods that are registered in the AnonCreds Methods Registry.

The specification leverages HCS-1 standard for storing immutable files on Hedera Consensus Service (HCS). All the published AnonCreds objects except for RevRegEntry are treated as HCS-1 files in this AnonCreds method (Schema, CredDef, RevRegDef).

For details about Hedera DIDs and how to write/read them, please see Hedera DID Method specification.
