Core Components of On-Chain Supply Chain Solutions

1. Distributed Ledger Technology (DLT)

• Public vs. Private Blockchains: Choose based on permission needs.
• Layer 1 vs. Layer 2 Solutions: Balance security and scalability.

2. Digital Asset Representation

• Tokenization of Goods: Digital twins or NFTs representing physical assets.
• Certificates & Licenses: Digitize certifications for authenticity.

3. Smart Contracts

• Automated Workflows: Trigger payments, notifications, or regulatory checks.
• Conditional Logic: Enforce compliance, such as quality thresholds.

4. Oracles and Data Feeds

• Real-World Data Integration: Connect on-chain data with IoT sensors and external sources.
• Trusted Data Validation: Use multiple oracles for redundancy.

Practical Implementation Steps

Step 1: Assess Supply Chain Complexity

• Map stakeholders, data flow, and pain points.
• Identify assets suitable for tokenization.

Step 2: Select Appropriate Blockchain Platform

• Hyperledger Fabric: For enterprise-grade permissioned networks.
• Ethereum (with Layer 2): For flexibility and widespread adoption.
• Polygon or Avalanche: For scalability and lower costs.

Step 3: Design Digital Asset Models

• Define metadata schemas for products, including origin, batch number, and quality data.
• Implement NFTs for unique items; ERC-721 or ERC-1155 standards.

Step 4: Develop Smart Contracts

• Automate processes such as customs clearance, payments, and inventory updates.
• Incorporate compliance logic based on industry standards (e.g., GS1).

Step 5: Integrate IoT Devices and Oracles

• Use IoT sensors for real-time tracking (GPS, temperature, humidity).
• Connect sensors via oracles to feed data on-chain securely.

Step 6: Pilot and Iterate

• Run small-scale pilots with select partners.
• Collect data, refine smart contracts, and expand gradually.
