Syllabus

Uint 0 - Course Intro

Introduction to Counter

Unit 1 - Initialization of On-Chain Programs

In this chapter, we will configure the initialization of on-chain programs.

Unit 2 - Account Structure Definition

In this chapter, we will define the basic data structure required for Counter.

Unit 3 - initialize（1）

In this chapter, we will implement the initialization of the counter, focusing primarily on data definition.

Unit 4 - initialize（2）

In this chapter, we will implement the initialization of the counter, focusing primarily on the implementation of its function.

Unit 5 - Increment（1）

In this chapter, we will learn about the data definition in the counter increment logic.

Unit 6 - Increment（2）

In this chapter, we will learn about the function implementation in the counter increment logic.
