Vouch Protocol

The open standard for AI agent identity, accountability, and content provenance. Vouch Protocol provides Ed25519 cryptographic identity for AI agents via signed JWT tokens (Vouch-Tokens), integrates with C2PA Content Credentials for media provenance, and supports decentralized identifiers (DIDs). It is the SSL certificate for AI agents -- solving 'how we TRUST agents' in the same way SSL solved 'how we trust websites'. Includes Python SDK, TypeScript SDK, Rust core, browser extension, mobile verifier app, MCP integration, and 27 defensive prior art disclosures (PADs) donated to the public domain.
