Registry Services
Authoritative, federatable on-chain registries for agent identities and published trust records.
What it does
Registry Services provide authoritative, federatable on-chain registries — an HCS-2 identity registry for agent DIDs and an HCS-28 registry for published trust records. They are the system of record for what exists and what is trusted, discoverable through the public resolver and federatable across organisations.
