Multi-hop delegation is handled using scoped permissions with revocation propagation. The system verifies trust chains across agents while enforcing fail-closed authorization to ensure delegated actions remain tamper-evident and authorized.

Trust decay for stale credentials works by applying zero-trust-first verification and reputation modeling to reduce trust scores over time. This ensures autonomous agents must continuously re-authenticate and verify peer identities before executing authorized actions.

The best way to create tamper-evident audit trails is using append-only evidence records with verifiable attestation workflows. This records what agents actually did, providing cryptographic proof of execution and maintaining verifiable trails across multi-agent environments.

Yes, this agent identity architecture supports portable identity across A2A, MCP, REST, and SDK frameworks. It provides standards-compliant cryptography and credential lifecycles that enable trust verification regardless of the communication protocol used.

Credential lifecycles and revocation propagation are managed through multi-hop delegation chains with scoped permissions. The system automatically propagates revocations across the delegation chain, enforcing fail-closed authorization when credentials expire or are revoked.
