Problem Statement

The ProductTracker project is a decentralized application that uses a Solidity smart contract on the Ethereum blockchain to register, track, and manage products throughout their lifecycle. The primary purpose is to enhance supply chain transparency, prevent fraud, and ensure product authenticity.Key Features: Product Registration: Users can register new products, storing details like name, manufacturer, and owner. Status Updates: Owners can update a product’s status (e.g., "In Transit", "Delivered") to track its journey. Ownership Transfers: Products can be sold, transferring ownership to new users while maintaining a full history on the blockchain. Transparency: Every action is recorded immutably, ensuring traceability and preventing tampering. Use Cases: Supply Chain Management: Track products from creation to sale. Anti-Counterfeiting: Verify product authenticity. Decentralized Marketplaces: Enable secure peer-to-peer sales with verified ownership. This system is ideal for industries that require trust and transparency, such as pharmaceuticals, luxury goods, and electronics.

Solution

The ProductTracker project was built using Solidity to create a decentralized application on the Ethereum blockchain for tracking products throughout their lifecycle.Technologies Used: Solidity & Remix IDE: Core development was done in Solidity using Remix IDE for quick prototyping and testing. Hardhat: Used for more extensive testing and local deployments. Web3.js & MetaMask: These tools enable interaction with the contract through a web interface and secure transactions. Key Design Details: Data Storage: Uses mappings for efficient product tracking and quick lookups. Events: Tracks actions like product registration, status updates, and ownership transfers, allowing for real-time transparency. Access Control: Restricted updates to product owners using Solidity modifiers. Gas Optimization: Efficient data structures like mappings and timestamps reduce gas costs. Notable Implementations: An event-driven architecture improves transparency. Efficient use of storage to minimize costs. Potential integration with IPFS for decentralized storage of product metadata and Chainlink oracles for automated status updates. This setup provides a scalable solution for transparent and tamper-proof supply chain management.
