Distributed Ledger for Supply Chain Resilience

Create a blockchain-based solution that enhances the traceability and transparency of critical supply chains, ensuring continuity and integrity in times of crisis. The platform should conform to global supply chain standards and frameworks, such as GS1 standards for product identification and ISO 28000 for supply chain security.

Disruptions in supply chains during emergencies can lead to severe economic and humanitarian consequences. A blockchain-powered approach can provide real-time visibility into supply chain transactions, improve accountability, and facilitate rapid response. By integrating globally recognized standards, such as GS1’s EPCIS (Electronic Product Code Information Services) and ISO 22095 chain-of-custody requirements, this solution ensures a secure, interoperable environment. Trusted oracles and industry-grade blockchain networks (e.g., Hyperledger, Ethereum) will provide the foundational infrastructure.

This bounty focuses on developing a blockchain-based platform that delivers secure, verifiable, and standards-compliant supply chain transparency. By following international frameworks and providing a clear audit trail of transactions, the solution will improve resilience, reduce waste, and help ensure the timely delivery of critical goods during disruptions. Comprehensive implementation documentation and open-source smart contract libraries will make the system accessible and scalable.

Target Outcomes:

• A blockchain prototype that integrates GS1 and ISO 28000 standards.
• Demonstrable improvements in supply chain visibility and responsiveness.
• Open-source smart contracts and deployment guidelines.

10 Steps

• Assess current supply chain security standards (e.g., ISO 28000) and identify the key vulnerabilities that can be addressed with blockchain technology
• Define the technical architecture of a distributed ledger system, including consensus mechanisms (e.g., Proof of Authority, Byzantine Fault Tolerance) and the choice of a suitable blockchain platform (e.g., Hyperledger Fabric, Ethereum)
• Design smart contract templates that enforce supply chain integrity rules, such as automated checks for counterfeit goods and transparent recordkeeping of shipment conditions
• Implement a secure data on-boarding process, using standardized data schemas (e.g., GS1 EPCIS) and trusted data sources to ensure consistent and verifiable inputs
• Integrate IoT-enabled tracking devices with the blockchain platform to feed real-time shipment conditions (e.g., temperature, humidity) into the distributed ledger
• Develop an API layer and user dashboard for supply chain managers to monitor the status of goods, verify authenticity, and receive automated alerts on potential disruptions
• Perform extensive security audits of the blockchain implementation, following best practices outlined by blockchain security guidelines (e.g., ConsenSys, OWASP)
• Conduct pilot tests with sample supply chain networks to evaluate system performance, scalability, and compliance with regulatory frameworks (e.g., ISO 22301 for business continuity)
• Optimize smart contract logic to reduce transaction costs, increase throughput, and ensure interoperability with existing supply chain management systems
• Deliver a full implementation guide, including blockchain deployment scripts, integration workflows, and a best practices manual for supply chain stakeholders
