I’m building a check-in app for a drug recovery drop-in center using Midnight’s ZKP technology.
42 CFR Part 2 is a federal law that protects substance use treatment records — even stricter than HIPAA. It means you can’t disclose that someone is even a patient without their consent.
My question: Can a Zero Knowledge Proof prove that someone checked in without revealing their identity or treatment status to anyone?
Has anyone explored using Midnight for healthcare or sensitive data compliance use cases? Any guidance appreciated!

Welcome to the community, DR.Ecovery! This is a fascinating use case.
The short answer is yes. This is exactly the kind of ‘selective disclosure’ Midnight is designed for.
In a Midnight-based app, you can use a Zero Knowledge Proof to verify that a state transition occurred (e.g., ‘a valid patient checked in’) without revealing the underlying private data (the patient’s identity or status) on the public ledger. To an observer, the proof confirms the event is valid according to your rules, but the data remains shielded.
Healthcare compliance is a major area of interest for the ecosystem. I’ll share this thread for our devrel team to see if we have specific compliance frameworks or similar projects to share.
Looking forward to seeing how this develops!
