JEP Core

Status: Alpha — Work in Progress
IETF Draft: draft-wang-hjs-judgment-event-00

Rust implementation of JEP: A Judgment Event Protocol for cross-platform AI accountability attribution.

Overview

JEP provides minimal, portable, cryptographically verifiable proof of who is responsible for AI decisions. This crate implements the core protocol:

• 4 Primitives: Judge, Delegate, Terminate, Verify
• Portable Receipts: Self-contained verification credentials
• 3 Verification Modes: platform, open, dual
• IETF Standards: UUIDv7 (RFC 9562), JCS (RFC 8785)

Quick Start

# Build
cargo build --release

# Run CLI
cargo run --bin hjs -- --help

# Create a Judge event (placeholder)
cargo run --bin jep -- judge \
  --actor "did:example:ai-agent-1" \
  --decision-hash "sha256:abc123..." \
  --authority "https://policy.example.com/v1" \
  --from 1712345678 \
  --until 1714937678
