The Central Question
Can privacy and regulatory compliance coexist on-chain? Zero-knowledge proofs offer a third path: prove you satisfy KYC, sanctions screening, or accredited investor requirements without revealing your identity. This project formalizes shielded compliance in Lean 4: ZK compliance predicates as circuits, shielded transfers with proof attachments, selective disclosure, and credential revocation that doesn’t deanonymize past transactions.
