HSP Protocol: Fail-Closed Execution Layer for AI (Open Source)

HSP: The Human Supervision Protocol

Just open-sourced HSP Protocol - a fail-closed execution layer that enforces human oversight on autonomous AI.

The Problem

Current AI safety (RLHF, Constitutional AI) is 99.9% effective. But 99.9% means 1 in 1,000 actions can fail. For autonomous AI in finance/healthcare, that's unacceptable.

The Solution

HSP flips the model:

  • Default state: BLOCKED (not allowed)
  • Actions only execute after human cryptographic signature
  • Every approval recorded on blockchain

Features

  • Smart contract on Polygon (live)
  • JavaScript & Python SDKs
  • Mathematical risk scoring framework
  • EU AI Act compliant
