What is BioPassport Token (BIOT)?

Deep Dive

1. Purpose & Value Proposition

BIOT powers a platform aiming to decentralize healthcare data ownership. Users store encrypted medical records (like lab results or prescriptions) in a Decentralized Personal Health Record (DPHR) system, granting access only through their biometric authentication. This addresses vulnerabilities in centralized health databases prone to breaches (BioPassport Whitepaper).

The token also incentivizes data sharing: users earn BIOT for contributing anonymized health data to research institutions or pharmaceutical companies via a marketplace. Consultants (doctors, therapists) similarly earn tokens for remote services.

2. Technology & Architecture

Built as an Ethereum sub-chain, BioPassport uses Acyclic Directional Hash Chain (ADHC) consensus for transaction validation. This hybrid model combines Ethereum’s security with a lightweight structure for healthcare-specific data flows.

Key technical features:
- Biometric encryption: Data requires both private keys and biometric verification (e.g., fingerprints) to decrypt.
- Multi-party access control: Patients can grant temporary access to specific records using mECDH encryption, ensuring privacy during telemedicine consultations.

3. Tokenomics & Governance

With 8.8 billion total ERC-20 tokens, BIOT’s utility includes:
- Purchasing diagnostic kits or medical tourism packages.
- Staking to participate in network validation.
- Rewards for health milestones (e.g., exercise tracking).

Notably, 100% of token transaction fees fund a reward pool redistributed to active ecosystem participants (CoinMarketCap).

Conclusion

BioPassport Token bridges blockchain innovation with healthcare’s urgent need for data sovereignty—offering users control while creating markets for anonymized medical insights. As regulatory landscapes evolve, can BIOT’s biometric-DID framework become a standard for secure health data exchange?
