Ethical Supply Chain Tracking System
The Ethical Supply Chain Tracking System is a blockchain-based platform designed to ensure transparency and accountability in the pharmaceutical supply chain. The system implements multi-authority threshold validation, where designated regulatory authorities must approve products at each stage before they can proceed through the supply chain.
Built on the Sepolia Ethereum testnet, every stage transition, approval, and rejection is permanently recorded on-chain, providing an immutable audit trail accessible to all stakeholders.
| Module Name | Description |
|---|---|
| Role-Based Access Control | Administrator-controlled actor onboarding, revocation, and blacklist enforcement mechanisms. |
| Product Registry System | Optimized on-chain state fields maintain compact storage while preserving complete custody history. |
| Ethical Validation Framework | Designated authorities approve or reject certificate digests until configured threshold determines outcome. |
| Public Verification Portal | Any citizen may verify product stage, custodian, and validation status using product identification number. |
| Stage | Stage Name | Responsible Actor | Stage Description |
|---|---|---|---|
| 01 | Product Registration | Manufacturer | Product registered on-chain with unique identification and certificate digest. |
| 02 | Manufacturing Complete | Manufacturer | Batch enters ethical review stage. Cannot proceed without threshold approval. |
| 03 | Distribution | Distributor | Custody transfer authorized after authority threshold is reached. |
| 04 | Retail Stock | Retailer | Public traceability available through QR code and manual verification. |
| 05 | Sold to Consumer | Retailer | Lifecycle closes with immutable status and certificate reference on record. |
| Parameter | Value |
|---|---|
| Authority Threshold | 2 of 3 |
| On-Chain Storage | Optimized |
| Evidence Model | Hash + IPFS |
| Governance Model | Admin Registry |
Multi-Authority Threshold Validation
Multiple authority approval gate prevents single points of trust failure. Minimum quorum required for progression.
Immutable Audit Trail
Every stage transition, approval, and rejection is permanently recorded on the blockchain for transparency.
IPFS Evidence Storage
Certificates stored off-chain using decentralized storage with on-chain digest anchoring for cost-effective proof.
Blacklist Enforcement System
Compromised or unauthorized actors can be blacklisted without disrupting the entire supply chain operations.
