描述
The Counter Smart Contract is a foundational Solidity project that introduces the core concepts of Ethereum smart contract development in a simple and practical way. The contract maintains a single integer variable called count, which is permanently stored on the blockchain. Users can interact with the contract through three main functions — increment(), decrement(), and getCount().
When a user calls increment() or decrement(), the contract updates the count variable on-chain, demonstrating how transactions modify blockchain state and consume gas. The getCount() function, on the other hand, is a read-only (view) function that allows anyone to check the current value without any gas cost.
This project helps beginners understand how smart contracts handle data persistence, state changes, and public accessibility. It forms a strong base for learning more advanced concepts like access control, events, and contract ownership in future projects.
本次黑客松进展
During the hackathon, we successfully designed, developed, and deployed a basic **Solidity Counter Smart Contract** that demonstrates core blockchain principles. We started by defining the project scope and learning how state variables, functions, and transactions work in Ethereum. We then implemented the contract logic for incrementing, decrementing, and retrieving a counter value stored on-chain. After coding, we tested the contract on **Remix IDE** using the **JavaScript VM** to ensure that all functions worked as expected. Throughout the hackathon, we also explored Solidity syntax, smart contract deployment steps, and basic gas mechanics — gaining hands-on experience with **state management**, **user interaction**, and **smart contract debugging**.
