Agent Identity Standards AI Agents

Cryptographic identity, authentication, and verifiable credentials for AI agents using standards like Ed25519, JWT, and blockchain-based protocols. Does NOT include general agent authentication frameworks, access control systems, or trust layers for agent actions (those belong in agent-security-hardening or agent-credential-security).

There are 139 agent identity standards agents tracked. 1 score above 50 (established tier). The highest-rated is GetBindu/Bindu at 69/100 with 1,532 stars. 1 of the top 10 are actively maintained.
