ChainHealth is a simple verifiable medical data ledger for individuals.
It allows users to register themselves and store verifiable hashes of medical records on-chain for audit and verification — without exposing private data.
Built using Solidity (compiled to Solana via Solang), it provides a privacy-preserving, tamper-proof registry for patient health record hashes.
ChainHealth is a privacy-preserving medical data verification system that lets individuals securely anchor their health records on-chain without exposing sensitive information. Instead of storing actual documents, ChainHealth records cryptographic hashes, creating a permanent, tamper-proof proof-of-existence for each medical file. Patients gain a unified, self-owned audit trail that works across clinics, labs, and insurers, eliminating the fragmentation and trust issues common in today’s healthcare systems. Providers can instantly verify a document’s authenticity by checking its hash, ensuring it hasn’t been altered and genuinely belongs to the patient—without ever accessing the underlying data. Built using Solidity and compiled to Solana via Solang, the platform combines smart-contract transparency with high-performance, low-cost blockchain infrastructure. ChainHealth strengthens data integrity, speeds up verification processes, and empowers users with control over their medical record history.
ChainHealth fixes the problem of trusting medical records across clinics, insurers, and providers. Today, records are scattered, easy to alter, and hard to verify without exposing private data. ChainHealth stores only hashes of records on a tamper-proof ledger, letting patients prove authenticity and integrity without revealing the actual information. It creates a unified, privacy-preserving, patient-controlled audit trail for medical data.
ChainHealth provides a secure, privacy-preserving way for individuals to verify their medical records. Instead of storing sensitive data on-chain, it records only cryptographic hashes, creating a tamper-proof proof-of-existence for each health document. Patients control their own registry, and providers or insurers can instantly confirm authenticity by matching the hash—without ever seeing the underlying data. This delivers trusted verification, simplified audits, and stronger data integrity across the healthcare ecosystem.
