Project Description

In this project, we will get hands-on experience building a functional blockchain system from scratch using Go. We will explore the core concepts of blockchain, including blocks, hash functions, the proof of work algorithm, and transaction management.

We’ll begin by implementing the block structure and blockchain structures, and learn how hashes are computed and utilized within the blockchain by implementing hash functions. Next, we’ll create blocks, including the Genesis block and blockchain. We’ll implement the proof of work algorithm responsible for mining blocks in the blockchain and also delve into transactions and wallets within the blockchain system, creating a transaction structure that enables the secure and reliable transfer of assets within the blockchain network. Also, we’ll design and implement wallets with associated functions, allowing users to manage their digital assets effectively.
