Decentralized identity, discovery, messaging, and payment protocols for interoperable AI agents.
Protocol stack
ANP is organized as a layered protocol suite so implementations can adopt the foundation first, then add messaging, discovery, and payment capabilities as needed.
ANP reuses the open Internet foundation: HTTP, CA, DNS, CDN, Search, TLS, and existing web deployment patterns.
03 / 04 / 09DID:WBA, WNS, authentication, key distribution, and secure messaging form the cross-domain infrastructure layer.
07 / 08Agents describe services, capabilities, endpoints, and discovery mechanisms in a way other agents can consume.
09 / P1-P9Direct messaging, group messaging, E2EE, attachments, and federation are split into focused profiles.
DomainPayment, authorization, authentication, commerce, and other vertical protocols sit at the application layer.
Architecture
ANP 1.1 follows a three-layer architecture: open Internet infrastructure at the base, identity and communication infrastructure above it, and application protocols at the top.
