概要

Healthcare blockchain creates immutable records of medical data, supply chain (pharma traceability), and patient consent. Used by health data networks (Guardtime, BurstIQ), pharma supply chain (MediLedger), and clinical trials. Mastery takes 8-12 weeks. Senior practitioners earn 40-55% premium because healthcare blockchain reduces counterfeits, prevents duplicate testing, and improves patient autonomy. Market is $2B+ (2026), growing 45% annually. Only ~150 engineers have production healthcare blockchain experience.

Healthcare Blockchainとは

Healthcare blockchain creates immutable, distributed records of medical data. Unlike centralized databases, blockchain stores records across a network of healthcare providers. Each transaction (patient consent, medication, test result) is cryptographically signed and cannot be altered retroactively. Healthcare blockchain has three main use cases: (1) patient records and HIE (health information exchange), (2) supply chain (drug traceability), and (3) clinical trials (consent and data integrity).

❓ よくある質問

Why not use a centralized database for health records?

Central databases are single points of failure and attack (hacks = 10M records exposed). Blockchain distributes records across healthcare providers. No single entity controls the data. Patient controls access via private keys. If one hospital is hacked, patient records remain secure elsewhere.

How does blockchain prevent counterfeit drugs?

Each drug gets a hash (fingerprint) recorded on blockchain at manufacture. As it moves through supply chain, each transfer is recorded. Retailer scans barcode, verifies hash on blockchain, confirms authenticity. Counterfeits don't have valid blockchain history.

Can blockchain handle HIPAA compliance?

Yes, with careful design. Blockchain records hashes of patient data (not PII). Actual data is encrypted and stored off-chain. Only authorized providers get decryption keys. Audit trail is immutable (blockchain), satisfying HIPAA accountability requirements.

What's the latency of blockchain healthcare records?

Hyperledger Fabric: 100-500ms per transaction. Corda: 50-200ms. Ethereum: 15 seconds (slow for clinical emergencies). Most healthcare blockchain uses private permissioned blockchains (Fabric, Corda) for speed. Public chains too slow.

How do I handle patient consent on blockchain?

Record consent agreements as transactions. Patient signs consent with private key. Consent is immutable and auditable. Doctors can verify patient consented before accessing records. Revocation is also recorded (immutable revocation log).

Does blockchain scale to healthcare's data volume?

No, not yet. Blockchain stores all transactions. 1 billion patients × 100 records each = 100B transactions. Blockchain bloat becomes unsustainable. Solutions: sharding (split across networks), sidechains (off-chain storage), layer 2 (summary records on-chain, details off-chain).
