Blockchain Security & Smart Contract Exploitation
Overview
Blockchain technology introduces new models for decentralized trust, integrity, and data verification—but it also comes with unique vulnerabilities. This project explores blockchain’s role in cybersecurity, with a focus on smart contract security, decentralized identity, and real-world exploits.
What You Will Learn
- How blockchain enhances security through decentralization and immutability
- Common blockchain attack vectors (e.g., reentrancy, front-running, 51% attacks)
- Hands-on deployment and testing of smart contracts
- Identifying and patching vulnerabilities in smart contract code
- Use cases for blockchain in threat mitigation, identity, and secure logging
Hands-On Learning
Students will gain experience using:
- Ethereum testnets with tools like Remix IDE, Ganache, or Hardhat
- Solidity to write and analyze smart contracts
- Exploit simulations based on known Web3 attacks
- Blockchain-based logging and identity models

Blockchain Security & Smart Contract Exploitation Lab
Blockchain Security & Smart Contract Exploitation Lab Overview This lab introduces students to smart contract security by deploying vulnerable code on Ethereum testnets and executing common Web3 exploits. You’ll analyze and patch contract weaknesses while exploring blockchain’s role in cybersecurity. Lab Instructions 1. Setting Up Your Environment You will need: A browser with Remix IDE Alternatively: install Node.js, Hardhat, and Ganache locally A MetaMask wallet connected to the Goerli testnet (or use local testing network) 2. Deploy a Vulnerable Smart Contract Paste this Solidity code into Remix: ...
