PharmaChain
Pharmaceutical Supply Chain
Immutable provenance for every molecule in the chain.
PharmaChain is a pharmaceutical supply chain platform built on Hyperledger Fabric — a permissioned enterprise blockchain used by IBM, Walmart, and major financial institutions. Every event in the supply chain is recorded as a cryptographically signed, permanently immutable entry on the blockchain. No single company controls it. No one can alter it.
Every year, 500,000 people die from counterfeit or substandard medicines. In 2022, contaminated cough syrup killed 66 children in Gambia. PharmaChain establishes an unbreakable chain of custody from manufacturer to patient — and any patient can verify their medicine is authentic in seconds, with no login required.

Logic Layer
Government
Registers products, issues MA & GMP certs, initiates recalls
Manufacturer
Creates batches linked to valid MA/GMP; QC releases on-chain
Doctor
Issues prescriptions by WHO INN with dosage, expiry, and repeats
Pharmacy
Receives shipments; dispenses only with valid on-chain prescription
Patient
Verifies any batch publicly — no login, no fee, full EPCIS history
Government / Regulatory Authority
Registers medicinal products with full GS1 identifiers (GTIN, INN, ATC code). Issues Marketing Authorisations and GMP Certificates. Initiates Class I/II/III batch recalls with live regulatory oversight from the blockchain.
Manufacturer
Creates production batches linked to a valid MA and GMP Certificate — both validated by the smart contract. QC releases batches simulating Qualified Person certification per EU GMP Annex 16.
Doctor
Issues prescriptions using WHO International Nonproprietary Names (INN) — not brand names. Clinical fields include dosage, frequency, duration, indication, and repeats — enforced on-chain at dispensing.
Pharmacy
Receives shipments with EPCIS receive events recorded. Dispenses only with a valid, unexpired prescription — the smart contract validates product, patient, and allowed quantity.
Patient
Receives medicine and can verify it immediately via public portal — no login required. Enter any batch number to see the complete supply chain history, QC release date, expiry, and current recall status.
Tamper-proof by design
Each block contains a cryptographic hash of the previous block. Altering any historical record invalidates every subsequent block — detectable by all nodes instantly.
Role enforcement in chaincode
Access control is enforced in the smart contract, not just the UI. A manufacturer cannot dispense. A pharmacy cannot create a batch. Even bypassing the frontend, the blockchain rejects the transaction.
Two-organisation endorsement
Every transaction must be endorsed by two independent peer organisations before it commits to the ledger. No single party can unilaterally record a false transaction.
EPCIS event model
Industry-standard GS1 EPCIS event architecture — the same model used by major pharmaceutical companies globally for FMD and DSCSA compliance.
Prescription enforcement on-chain
A pharmacy cannot dispense without a valid, unexpired prescription covering the correct product for the correct patient. Enforced in the smart contract — not in the UI.
Public verifiability
Any patient, regulator, or journalist can verify any batch — no login, no account, no fee. The complete EPCIS event chain is publicly readable.
Core track-and-trace: product registration, MA/GMP management, batch lifecycle, prescription enforcement, public verification.
Industry terminology (MA, GMP, EPCIS), QC quarantine/release workflow, Class I/II/III recalls, patient portal, prescription clinical fields (INN, dosage, frequency, indication).
Multi-organisation network, HTTPS, pack-level serialisation (EU FMD), pseudonymous patient IDs (GDPR), monitoring, secrets management.
ERP integration (SAP, Oracle), IoT cold chain monitoring, mobile application (React Native), ADR/pharmacovigilance reporting, EMVS integration.
