AC2 Protocol adds cryptographic agent approvals
1 min read
AC2 Protocol, an open-source Algorand Foundation project, adds hardware-bound cryptographic signatures to AI agent approvals. It uses FIDO2 authenticators and DIDComm v2.0, requiring no blockchain or central relay. Agents request signatures without touching user keys, providing verifiable proof of intent for payments, code signing, and other sensitive operations.
