PSI Protocol – Cryptographic EU AI Act Compliance at $0.01 per Proof (IETF Draft Filed)

I'm a solo founder from Melbourne, Australia. I built this between jobs!No VC. No team. Just code and a deadline.
The Problem:
EU AI Act Article 50 goes live August 2, 2026. NDIS compliance deadline July 1, 2026. Every AI system needs tamper-evident, independently verifiable proof of compliance. Current solutions fail:
Full ZK-ML: $1,000+ per proof
Manual audits: $50K-$500K, periodic
Logging tools: self-reported, not independently verifiable
What I Built:
PSI Protocol — a cryptographic compliance infrastructure with:
SHA-256 + Ed25519 signatures + Binary Merkle trees
3-node MPC consensus
Article-mapped predicates (EU AI Act Articles 12, 13, 14, 15)
$0.01 per cryptographically signed compliance receipt
40 edge functions, 28 database tables, full enterprise platform
What makes this different:
Independent verifiability — regulators verify WITHOUT trusting us or you
IETF standardized — draft-singh-psi-01 filed March 21, 2026
Patent protected — AU2026902352
Article-mapped — every receipt maps to specific regulatory articles
Free forever — open source, $0.01 per proof
