Description

In this Build Project, you'll be asked to develop a smart contract that simulates a decentralized lottery system. Such a system requires transparency, security, and verifiability to ensure trust among participants. A smart contract is essentially a “black box” that executes predefined rules, but understanding its internal mechanics and ensuring its fairness can be complex. Therefore, comprehensive testing and evaluation are crucial to confirm the smart contract's reliability and performance.  Under the supervision of an experienced Build Fellow, you'll develop a fully functional smart contract that will be deployed in the Ethereum Sepolia Testnet. You'll also use various metrics and test simulations to identify potential vulnerabilities or failure modes.

What you will learn

  • Develop Smart Contracts: Learn how to write and deploy smart contracts using Solidity on the Ethereum blockchain.
  • Blockchain Fundamentals: Gain a foundational understanding of blockchain technology and its applications.
  • Decentralized Application Development: Explore the principles and practices of creating decentralized applications (dApps).
  • Testing and Debugging: Develop skills in testing and debugging smart contracts to ensure their reliability and security.
  • Basic Shell Scripting: Learn basic shell scripting techniques to automate tasks and enhance productivity.
Build Projects are 8-week experiences that operate on a rolling basis. Selected participants engage in weekly live workshops with a Build Fellow and 2-15 other students.
