Blockchain Basics
A blockchain is a shared database that features added immutability as a safe and accurate alternative to
existing data storage methods. Students will learn the basics of how the blockchain data model works by
creating their own private blockchain using Node.js and Leveldb. In this project, students will learn the
fundamentals of architecting a collection of data into a blockchain data model. Learners will configure how
each block stores data, validate blocks, add new blocks to the chain, and create methods to validate the
chain integrity.
Learners will then create a back end API web service, and migrate their private blockchain to the web
service. In the process, students will learn how to post new blocks to the blockchain via a RESTful web client.
Learners will then encrypt and decrypt the unique digital collectibles on a private blockchain.
