Today's AI agents browse the web pseudonymously. They present no identity, accept no responsibility, and operate entirely in the shadows of user-agents.
The agentic web needs something better: a lightweight identity layer that lets agents announce who they are, what they want, and who they work for — without requiring central registries or heavyweight authentication flows.
The Tollway DID approach uses the W3C did:key method with Ed25519 keypairs. Every agent generates a keypair locally; the public key becomes the DID. Requests are signed so servers can verify the agent is who they claim to be.
