Global Healthcare
Infrastructure
hospitals worldwide.
THE
PROBLEM
Today, hospitals worldwide run isolated systems. Patients must physically return to their original hospital just to retrieve and share medical records with other facilities.
THE
SOLUTION
CareChain creates a unified ecosystem where medical records move with patients, not locations. Cryptographic verification ensures data integrity while patients maintain complete ownership through secure key-based access.
How it Works.
A streamlined process ensuring security, ownership, and interoperability
Step 1
Hospital Onboards
Medical facilities register on the CareChain network with verified credentials.
Step 2
Doctor Issues Records
Authorized physicians create and co-sign encrypted medical records.
Step 3
Patient Owns Key
Patients receive cryptographic keys for complete record ownership.
Step 4
Cross-Hospital Verification
Any authorized facility can verify and access records with patient consent.
Core Features
What to expect?
On-Chain Verification
Each medical record is permanently verifiable on Solana’s blockchain, ensuring authenticity, tamper resistance, and transparent auditability.
Encrypted Record Bundles
Medical data is packaged into encrypted ZIP bundles containing structured metadata and attached files, enabling secure, portable, and interoperable sharing across institutions.
Hospital-Patient Co-Sign
Records are validated through dual signatures — one from the hospital and one from the patient — establishing undeniable proof of authenticity and consent on-chain.
Granular Access Control
Patients retain full control over their data, granting and revoking permissions for hospitals or doctors at any time with cryptographically enforced policies.
Off-Chain Indexing
Supabase provides efficient off-chain indexing and querying of encrypted record metadata, optimizing retrieval speed while maintaining data privacy.
Zero-Trust Infrastructure
Built on cryptographic principles, CareChain operates without centralized trust — every verification, signature, and access request is provable and independently verifiable.
Built on
CareChain leverages Solana's high-performance blockchain to achieve sub-second transaction finality, verifiable record integrity, and cryptographic guarantees at scale ensuring healthcare data remains fast, secure, and immutable.
