Threat Model

  1. Agent Impersonation — Mitigated by cryptographic identity
  2. Capability Escalation — Mitigated by strict capability boundaries
  3. Data Tampering — Mitigated by Merkle provenance chains
  4. Sybil Attacks — Mitigated by reputation + stake mechanisms
  5. Eclipse Attacks — Mitigated by diverse peer discovery
  6. Supply Chain — Mitigated by signed releases and reproducible builds
  7. Replay Attacks — Mitigated by nonce/timestamp checks
  8. Side Channel — Mitigated by constant-time crypto primitives
