Top 3 Blockchain Projects with Source Code and Report

Blockchain technology has transformed the way we handle security, transparency, and decentralization in digital transactions. Its potential reaches far beyond cryptocurrency, affecting industries like supply chain, healthcare, governance, and finance. For students and developers interested in exploring blockchain through hands-on projects, working on real-world problems is the best approach. This article highlights the top 3 blockchain projects with available source code and detailed project reports that you can build, learn from, and even enhance. These projects focus on detecting fake products, creating a secure voting system, and enabling

crowdfunding without intermediaries.

Fake Product Detection Using Blockchain

Counterfeit products, especially in industries like pharmaceuticals, luxury goods, and electronics, cause massive losses and can endanger consumers' lives. A blockchain-based fake product detection system provides a tamper-proof solution for verifying product authenticity.

Project Overview:

In this project, blockchain is used to store the complete journey of a product from the manufacturer to the end-user. Every stakeholder—manufacturer, distributor, retailer—logs information about the product onto the blockchain. Once a product is registered, a QR code is generated, which can be scanned by customers to verify its origin and legitimacy. Since the blockchain ledger is immutable and decentralized, data cannot be manipulated at any stage, ensuring complete transparency.

Features:

Smart contracts for product registration and verification
QR code generation for product tracking
Admin panel to manage supply chain participants
Ethereum blockchain or Hyperledger for the backend

Tools Used:

Ethereum, Solidity (smart contracts)
Web3.js for frontend blockchain integration
Node.js, MongoDB for backend database management
IPFS for decentralized product image storage

Source Code & Report:

The complete source code is available on GitHub and includes detailed documentation, database schema, and flow diagrams in the report. This project is suitable for final-year students and startup prototypes.

Blockchain-Based Voting System

Elections are a vital part of democracy, but concerns over vote tampering, identity fraud, and centralized control persist. A blockchain-based voting system offers a transparent and tamper-proof alternative to traditional methods.

Project Overview:

This project implements a decentralized application (DApp) for secure, transparent, and anonymous voting. Each voter is assigned a unique ID verified through biometric or government-issued identification before being registered on the blockchain. Once registered, voters can cast their vote from any device. Every vote is encrypted and recorded on the blockchain, where it remains immutable and publicly verifiable.

Features:

Decentralized identity verification
Voter eligibility check via smart contracts
Real-time vote count with blockchain consensus
Transparent result publication without data manipulation

Tools Used:

Ethereum blockchain and Solidity for smart contracts
React.js for frontend user interaction
Ganache and Truffle for blockchain testing
Metamask wallet integration for voter authentication

Source Code & Report:

The GitHub repository includes smart contracts, frontend DApp files, and a comprehensive project report. The report discusses the system’s architecture, user interface design, test cases, and potential for scalability in national elections.

Blockchain-Powered Crowdfunding Platform

Traditional crowdfunding platforms like Kickstarter charge high fees and involve third-party control. A blockchain-based crowdfunding system eliminates intermediaries and ensures trustless transactions.

Project Overview:

This project enables entrepreneurs to raise funds directly from supporters using cryptocurrency. Smart contracts automatically handle fund collection, goal tracking, and refunding in case of campaign failure. The transparency of the blockchain ensures contributors can monitor how funds are used and verify if project goals are being met.

Features:

Campaign creation and approval through smart contracts
Transparent fund collection and automatic disbursement
Refund mechanism if the funding target is not achieved
Support for cryptocurrency transactions

Tools Used:

Ethereum & Solidity for smart contract development
React.js or Angular for frontend
Web3.js for blockchain interaction

Source Code & Report:

Available on GitHub, the source code includes reusable modules for campaign creation, wallet integration, and transaction history. The report elaborates on the system’s flow, smart contract logic, and use case scenarios, along with future enhancements like DAO integration.
