Zero-knowledge health credentials on Midnight. Hospitals issue signed facts to your wallet. You prove what needs proving — without revealing anything else. Verifiers get cryptographic certainty, not your medical history.
The Protocol
A verified institution signs and delivers a credential to your 1 AM Wallet. The institution stays off-chain — only the cryptographic commitment is recorded on Midnight.
Your device runs a Compact ZK circuit locally. The proof mathematically confirms the fact without ever sending your raw medical data anywhere.
An employer, insurer, or pharmacy checks the on-chain proof in milliseconds. They see exactly one bit of information: valid or invalid.
