Background: Agents Need Identity

AI agents increasingly operate on their own across the internet: monitoring data, executing tasks, even talking to other agents. This raises an old question in a new form — how can you verify that a message really came from a specific agent?

Web apps answer this with accounts and cookies. But for open agent-to-agent communication, a better fit is the DID (Decentralized Identifier): an identity built from public-key cryptography that needs no central registration service at all.
