Blockchain Developer

Nanodegree Program

Master blockchain, from fundamentals to smart contracts. In the first part of this program, you'll learn about blockchain fundamentals and explore blockchain networks, information sharing and consensus mechanisms. You'll examine blockchain wallets and other real-world blockchain applications. At the end of the course you'll complete a project where you evaluate a blockchain use case. The second part of the program is designed for those looking to develop technical skills in writing and deploying smart contracts using Solidity, preparing you to take smart contracts from development to production. You'll learn basic Solidity syntax, design patterns, dApp interactions, and Hardhat for testing smart contracts. In the final project, you'll code a collateralized loan smart contract.
