Prove health facts.
Share zero data.
VeriHealth is an on-chain credential network. Hospitals issue facts. Patients prove them cryptographically using Midnight. Verifiers get absolute certainty without ever seeing a medical record.

The Protocol
Three actors. One cryptographic truth.
Hospital Issues
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.
Patient Proves
Your device runs a Compact ZK circuit locally. The proof mathematically confirms the fact without ever sending your raw medical data anywhere.
Verifier Confirms
An employer, insurer, or pharmacy checks the on-chain proof in milliseconds. They see exactly one bit of information: valid or invalid.
What Beta Testers Say
Real feedback from our PREPROD testing cohorts.
"Finally, I can prove my vaccination status without handing over a PDF that has my date of birth, home address, and full name. This is how all health apps should work."
"As an HR manager, I don't want the liability of storing people's actual medical records. Seeing a green 'VALID' checkmark from the blockchain is all we legally need."
"The Zero-Knowledge proof generation takes less than 30 seconds on my phone. The UI makes the cryptography completely invisible."
