ANP (Agent Network Protocol) is an open-source protocol for inter-agent communication. It features a three-layer structure: an identification and secure communication layer that implements authentication and encrypted communication based on the W3C DID specification; a meta-protocol layer for negotiating communication protocols; and an application protocol layer that describes capabilities based on semantic web specifications.
ChangShan (@changgaowei): ANP 1.1 is officially released after three months of refinement and community review.
Highlights: did:wba + native did:web interoperability; human-readable Handles; DID-integrated 1:1 and group messaging; attachment manifests; and E2E encryption with Signal-inspired sessions and

Agent Network Protocol (ANP) is an open-source protocol suite for agent identity, discovery, messaging, and collaboration, aiming to enable secure and efficient agent networks as the HTTP of the Agentic Web era.
@changgaowei: The latest version of ANP has been released. Supporting open-source projects will be rolled out gradually—stay tuned. This article is technical in nature. In one sentence: ANP has made inter-agent cross-domain communication more solid. Email can also do cross-domain communication, but it has two fatal flaws: one is the heavy historical baggage of the protocol, so basically no one explores agent protocols based on email; the other is identity—email identities are hard to adapt for agents. I'll dive into this topic another day.
The latest version of ANP (Agent Network Protocol) has been released, with supporting open-source projects to follow. This protocol has made substantial improvements in cross-domain communication for agents, and is better suited to agent identity and communication needs compared to the Email protocol.

Introduces the Agent Network Protocol (ANP), an open-source communication protocol aiming to become the HTTP of the Agentic Web era by enabling agent identity, discovery, messaging, and collaboration. The post also reflects on how the web became siloed due to human-centric efficiency, arguing for a protocol-centric agent internet.
@changgaowei: Agree, if a messaging protocol doesn't handle identity, cross-domain is just a channel. ANP splits these two layers and reconnects them: `did:wba` answers who you are and how to verify, while the messaging Profile (1:1 / Group / E2EE / Federated) only handles how to transmit. Identity can also be used for payments, authorization, and isn't tied to a single IM...
ANP is an open-source protocol designed to provide standards for identity, naming, discovery, and secure communication for intelligent agents, separating identity from message delivery to enable cross-domain collaboration.
@changgaowei: Cross-machine agent conversations are the right problem. We split it the same way: identity first (`did:wba`), then mes…
