Mission Brief

Aegis Care is a decentralized healthcare management system engineered on the Algorand blockchain. It replaces vulnerable centralized electronic health records with cryptographically signed, immutable smart contracts and distributed IPFS storage. Patients maintain sovereign ownership over their medical records, granting temporary, revocable access to certified practitioners. The platform eliminates medical prescription forgery and ensures HIPAA-compliant data integrity.

Key Features

Smart Contract Architecture

  • Role-Based Access: On-chain PyTeal contracts regulating patient permissions, doctor credentials, and pharmacist validations
  • Tamper-Proof Prescriptions: Digital prescriptions hashed and anchored directly to the Algorand blockchain
  • Revocable Consent: Patients can grant and revoke temporary doctor access to diagnostic records at any time

Decentralized Storage (IPFS)

  • CID Content Addressing: Heavy medical scans and lab reports are stored on IPFS with cryptographic CID hashes
  • Client-Side Encryption: AES-256 encrypted payload before IPFS pinning ensures only authorized private keys can decrypt files
  • Integrity Verification: Automated on-chain hash verification ensuring zero tampering of diagnostic reports

Engineering Chronicles

Storing high-resolution MRI and CT scans directly on-chain is cost-prohibitive on blockchain networks.

SolutionStored encrypted medical assets off-chain on IPFS and anchored only the SHA-256 content identifier hash inside Algorand smart contract state storage.

Doctor verification needed to prevent unauthorized entities from writing medical prescriptions.

SolutionBuilt a multi-signature administrative gate validating medical council licenses on-chain prior to granting practitioner permissions.
