Elixir-native A2A discovery and messaging protocol for agent marketplaces
Elixir

How It Works
Implements a bespoke agent-to-agent discovery and communication protocol for Elixir applications. Uses peer-to-peer patterns and Phoenix/WebSocket primitives to let agents find one another, exchange metadata and messages, and form transient marketplaces. Distinctive features include lightweight discovery for decentralized agent marketplaces and Elixir-native concurrency for high-throughput agent messaging. This supports multi-agent trust.
Why It Matters
As agents proliferate, reliably discovering and connecting to other agents is a prerequisite for any reputation or evaluation system. This protocol fills the gap by providing a runtime-level discovery and messaging layer so agent interactions can be observed, correlated, and attributed. That visibility is essential for building agent track records, running A2A evaluation, and surfacing trust signals across decentralized marketplaces. This design aligns with Agent-to-Agent Protocol (A2A) and supports Evaluation-Driven Development (EDDOps).
Target Use Cases
Elixir teams building peer-to-peer agent marketplaces or multi-agent systems that need an in-process discovery and messaging layer.
Use Cases
- Enable peer discovery and handshake between autonomous agents in a decentralized marketplace
- Stream agent interaction logs for downstream reputation and A2A evaluation systems
- Route messages between specialist agents with Elixir's concurrency and Phoenix WebSocket transport
