WELL is a patient-centric platform that gives individuals sovereign control over their clinical data through blockchain-backed consent management and secure cloud storage.
Private keys stored securely. Every access logged on-chain. Consent managed by the patient — always.
Electronic Health Records (EHRs) contain deeply personal information, yet today their storage and sharing are entirely controlled by healthcare institutions. Patients cannot verify who accessed their data, cannot enforce consent, and cannot carry their records across different healthcare providers — public or private.
Portugal's NHS (SNS) stores records centrally via SPMS, while private institutions maintain isolated silos. GDPR grants patients rights of access and deletion, but the infrastructure to enforce them simply doesn't exist.
Patients share records without exposing unnecessary personal data — powered by Hyperledger Indy.
Every access — creation, modification, consultation, deletion — is recorded on-chain and cannot be altered.
A cloud-of-clouds architecture (RockFS) distributes records across multiple providers, ensuring resilience to outages.
Right to Access and Right to be Forgotten are enforced by design through smart contracts and consent management.
A hybrid back-end combining a cloud-of-clouds storage layer (RockFS) with a permissioned blockchain (Hyperledger Fabric). Data is secret-shared across N public clouds so that no single provider can reconstruct an EHR.
An Android application that puts patients in full control. The wallet securely stores private keys and interacts with the repository to access, share, and manage EHRs — from anywhere in the world.
Android client application for patients, medical staff, and insurers.
Hybrid cloud-of-clouds + blockchain back-end storage system.
Solidity / chaincode for access control and consent management.
Hyperledger Fabric chaincode integrated with the WELL Wallet.
