DCP-AI – Portable accountability layer for AI agents (post-quantum)(github.com)

  Author here. Started building this in January. The protocol went public
  on GitHub in February; the companion paper landed on Zenodo in March
  (https://doi.org/10.5281/zenodo.19040913). Today the whole stack is
  finally installable from every registry — 17 packages across npm, PyPI,
  crates.io, and Go modules.

  The thesis: agents fail from missing infrastructure, not missing
  intelligence. Human societies didn't coordinate by perfecting individuals —
  they invented institutions. DCP-AI is an attempt at that scaffolding for
  autonomous AI: cryptographic identity bound to a responsible human,
  machine-readable intents with policy gating, tamper-evident audit chains,
  a formal lifecycle/succession/rights framework, and an agent-to-agent
  arbitration protocol.

  Hybrid post-quantum crypto (Ed25519 + ML-DSA-65 composite, NIST FIPS
  203/204/205 conformant). Apache-2.0.

  Quick things to try:
  - Interactive playground: https://dcp-ai.org/playground/
  - npm create @dcp-ai/langchain my-app (or /crewai, /openai, /express)
  - Docs: https://docs.dcp-ai.org

  Happy to discuss design choices. Most interested in pushback on DCP-07
  (agent-to-agent conflict arbitration) — that's where the design was
  hardest to commit to.
