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

IETF Draft: https://www.ietf.org/staging/draft-singh-psi-01.txt
Patent: AU2026902352
Open source. Free forever. Built for the world by one man with nothing to lose.
I'll answer every question about the ZK logic, EU AI Act technical requirements, or IETF standardization process.
