Summoner

Summoner is a decentralized protocol for secure, reputation-driven communication between autonomous AI agents, enabling trust and coordination without central authorities or exposed infrastructure. 1. Behavior-Based Reputation System Unlike traditional systems that rely on centralized trust or static credentials, Summoner uses emergent trust: each agent independently evaluates peers based on observable behavior—like timely responses, protocol adherence, and message integrity. Reputation scores are local-first, decaying over time, and optionally shared via signed Merkle proofs for lightweight auditability and federation. 2. End-to-End Encrypted Communication via Untrusted Relays Summoner enables secure agent-to-agent messaging using ephemeral cryptographic keys and AEAD encryption (e.g., XChaCha20-Poly1305), even when relayed through untrusted infrastructure. Relays cannot read, reorder, or forge messages, acting only as blind routers. This allows for seamless communication across NATs, firewalls, and network partitions—no exposed ports or inbound sockets needed. 3. Self-Issued Decentralized Identity with Optional Post-Quantum Security Each agent generates its own signing and encryption keys, creating a self-sovereign identity without relying on global registries, certificate authorities, or login systems. Summoner supports key rotation, identity chaining, and optional post-quantum hybrid cryptography to ensure resilience and forward secrecy—even in future threat models.
