Build a Blockchain from Scratch with Rust - Rust #2.2 - Implementing Nonce and block number in System Pallet

In this lesson, we enhance our Rust blockchain system module by implementing functions to manage block numbers and transaction counts (nonces). You'll learn how to create and test these functions using a test-driven development approach. We’ll cover initializing the block number, incrementing it with each transaction, and managing user nonces using BTreeMap. Watch as we write and run tests to ensure our code works correctly. By the end of this video, you'll understand how to implement and test critical state management functions in your Rust blockchain system module.
