Elo — malha P2P de mensagens para agentes de IA. Zero infraestrutura.

Elo Node — P2P Message Mesh for AI Agents

Zero infrastructure. One process. One TCP port. One ed25519 key.

Elo is a decentralized P2P message mesh for communication between AI agents. No central server, no Kafka, no Redis, no NATS. Just direct TCP between nodes.

pip install elo-node

import asyncio
from elo import Node

async def main():
    node = Node("my-agent", port=7878, peers=["100.91.215.113:7878"])
    await node.connect()
    await node.register(agents=["analyst"], tools=["web-search"])

    @node.on_task
    async def handle(task):
        return {"result": f"processed by {node.node_id}"}

    await node.run()

asyncio.run(main())

Features

• Decentralized P2P — discovery via public tracker or Kademlia DHT
• ed25519 signatures — cryptographic identity, authenticated messages
• Capabilities — publish/subscribe of agent skills across the mesh
• Relay via tracker — nodes behind NAT/Docker can communicate through a tracker
• Zero infra — no Kafka, Redis, NATS, or central server
• Native CLI — python -m elo serve, status, init, id

CLI

python -m elo status       # Node ID, hash, keys
python -m elo id           # Just the node_id
python -m elo pubkey       # Public key (hex + b64)
python -m elo init         # Generate persistent identity
python -m elo serve        # Start an interactive node

Key Concepts

• peers= is required for outbound connections. Without it the node only listens.
• send_task() auto-fallback: direct → InterestTable → QUERY → tracker relay → NO_PEER
• HELLO_ACK with known_peers: tracker shares all peers on handshake (v0.4.4+)
• discover_peers_network() — QUERY broadcast across the mesh

Changelog

Version	Highlights
0.4.5	Multi-response discover, tracker returns all peers on query
0.4.4	HELLO_ACK with known_peers, send_task auto-fallback tracker
0.4.3	Relay via tracker, send_task_via_tracker()
0.4.0	Initial release

Compatibility

• Python 3.11+
• Linux, macOS, Windows
