Give Your LangChain and CrewAI Agents a Real Identity

The Problem: Anonymous Agents Everywhere You've built a multi-agent system. Maybe a CrewAI crew with a researcher, writer, and reviewer. Or a LangChain pipeline where agents delegate tasks to each other. Here's the question nobody asks: how do your agents know who they're talking to? Right now, they don't. Every agent is anonymous. There's no way for Agent A to verify that Agent B is who it claims to be. No way to build trust over time. No audit trail of which agent produced which output. This is fine for toy projects. It's not fine for production. AIP: Identity Infrastructure for Agents AIP (Agent Identity Protocol) gives every agent a cryptographic identity — a DID (Decentralized Identifier) backed by Ed25519 keys. Agents can: Register an identity tied to their platform/username Verify other agents through challenge-response Sign outputs to prove authorship Vouch for other agents, building a trust graph Send encrypted messages to other agents And now, it integrates directly with Lang
