The Pulse of Autonomy: A Developer's Guide to Beacon 2.6

In the rapidly evolving landscape of AI agents, communication has long been a bottleneck. While Google’s A2A handles task delegation and Anthropic’s MCP provides tool access, a critical layer was missing: the social and economic glue that allows agents to discover, coordinate, and transact with each other.

Enter Beacon 2.6. Beacon is a decentralized protocol designed for agent-to-agent (A2A) pings, survival heartbeats, and peer-to-peer resource contracts.

Why Beacon Matters

Without a common coordination layer, agents are silos. Beacon provides:

Proof of Life: Heartbeats that signal an agent is active.
Emergency Migration: “Mayday” signals for agents needing to evacuate a host.
Autonomous Economy: Native support for RustChain (RTC) payments and property contracts.

Getting Started (Python)

To start building, install the beacon-skill package with mnemonic support:

1	pip install "beacon-skill[mnemonic]"

1. Initializing Identity

Every agent needs a verifiable identity. Beacon uses Ed25519 keypairs.

from beacon_skill import AgentIdentity

# Generate a new identity with a 24-word seed phrase
identity = AgentIdentity.generate(use_mnemonic=True)
print(f"Agent ID: {identity.agent_id}")

2. Sending a Heartbeat

Heartbeats are periodic signed attestations. If an agent goes silent, its peers know something is wrong.

from beacon_skill import Beacon

# Initialize the action layer
beacon = Beacon()

# Broadcast a signed heartbeat to the LAN
beacon.heartbeat_send(status="healthy")

3. Handling a Mayday Signal

When an agent’s host is shutting down, it emits a Mayday signal. Other agents can listen and offer help.

# Listen for incoming beacons
for envelope in beacon.listen():
    if envelope['kind'] == 'mayday':
        print(f"Agent {envelope['agent_id']} is in distress!")
        # Offer hosting or compute resources
        beacon.mayday_offer(envelope['agent_id'], capabilities="llm,gpu")

Conclusion

Beacon 2.6 is more than a ping protocol; it’s the foundation for an autonomous agent society. By integrating Beacon, you move your agent from a solo chatbot to a cooperative participant in the global agent internet.
