Hi LangChain community, Multi-agent chains in LangGraph raise a question that's hard to answer today: when a sub-agent takes an action, which human authorized it, and with what scope? I've been working on HDP (Human Delegation Provenance Protocol) a cryptographic chain-of-custody spec for agentic AI. A human signs a token with Ed25519, agents extend the chain as they delegate, and any node can verify offline (no registry, no network call). npm: @helixar_ai/hdp Spec draft: https://datatracker.ietf.org/doc/draft-helixar-hdp-agentic-delegation/ Repo: https://github.com/Helixar-AI/HDP Would LangGraph benefit from a first-party HDP integration? Happy to contribute a LangGraph callback handler that auto-extends the delegation chain on node transitions. Curious what the team thinks. 1 post - 1 participant Read full topic
