Blockchain Supply Chain Tracking

A decentralized supply chain platform that provides immutable tracking, automated compliance verification, and real-time visibility from origin to destination.

The Challenge

A global logistics company faced transparency and trust issues:

• Limited visibility - Couldn't track products between handoffs
• Dispute resolution - Weeks to resolve shipping disputes
• Compliance burden - Manual audits for regulatory requirements
• Document fraud - Falsified certificates and shipping documents

They needed a tamper-proof system that all stakeholders could trust.

Our Approach

We combined blockchain's immutability with IoT sensors and smart contracts to create a comprehensive tracking solution.

Hybrid Architecture

1. On-Chain - Critical events and ownership transfers
2. Off-Chain - High-frequency sensor data on IPFS
3. Oracles - Bridge between IoT devices and blockchain
4. Smart Contracts - Automated verification and payments

The Solution

Blockchain Layer

• Ethereum mainnet for critical transactions
• Layer 2 scaling for high-frequency updates
• Smart contracts for automated workflows
• Multi-signature wallets for payments

IoT Integration

• Temperature and humidity sensors for perishables
• GPS tracking for real-time location
• Tamper-evident seals with NFC chips
• QR codes for mobile scanning

Stakeholder Portal

Smart Contract Features

Automated Verification

// Simplified example
function verifyHandoff(
    bytes32 shipmentId,
    address newCustodian
) external {
    require(msg.sender == currentCustodian);
    require(sensorDataValid(shipmentId));

    transferCustody(shipmentId, newCustodian);
    emit HandoffVerified(shipmentId, newCustodian);
}

Escrow Payments

• Automatic release on delivery confirmation
• Dispute resolution with arbitration
• Partial payments for milestones
