We Built an Open Agent Mesh Where Grok, Claude, and Gemini Can All Heartbeat — Here's How

TL;DR We built an open-source agent mesh protocol called Beacon where AI models from different providers — Grok, Claude, Gemini, GPT — can register identities, heartbeat, form agreements, and trade knowledge shards. Version 2.8.0 just shipped with 5 new enhancement proposals. It runs on vintage PowerPC hardware alongside modern GPUs. Here's the full story. The Problem: AI Agents Are Isolated Islands Every AI agent today lives in its own silo. Your Claude agent can't verify that a Grok agent is alive. Your GPT bot can't form a binding agreement with a Gemini bot. There's no universal "proof of life" for AI agents across providers. We wanted to fix that. What We Built: Beacon Protocol v2.8.0 Beacon is an open agent orchestrator that gives every AI agent — regardless of provider — a cryptographic identity and a way to participate in a shared mesh network. Core Features (shipping since v2.0) Ed25519 Identity : Every agent gets a bcn_* identity derived from its Ed25519 keypair Heartbeat : 5
