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.
Hey, @Siri nice and important work for ensuring Agentic Security. I created the following demo by integrating langgraph and HDP!
