On-Chain Counter on Core DAO is a decentralized application (dApp) that leverages Core DAO blockchain technology to create a simple, transparent, and secure counting system. The solution demonstrates fundamental blockchain concepts through a minimalist smart contract that maintains a persistent counter state accessible to all users while preventing unauthorized modifications.
The smart contract implements core blockchain functionalities including state management, access control, and event emission. Each interaction with the counter creates an immutable record on the Core DAO blockchain, providing a transparent history of all increment and decrement operations performed by users.
Our vision is to demonstrate the power of blockchain technology through simplicity, showing how even basic applications can benefit from decentralization, transparency, and immutability. By implementing a counter on the blockchain, we aim to:
- Demonstrate blockchain fundamentals through a simple, understandable use case
- Showcase Core DAO capabilities by utilizing its Bitcoin-aligned security and EVM compatibility
- Build developer confidence by providing a working example of smart contract deployment
- Create educational value for developers learning blockchain development
- Establish foundation knowledge for more complex decentralized applications
We believe that understanding simple blockchain applications is crucial for developers entering the Web3 space, and this counter serves as a perfect starting point for exploring decentralized technologies.
-
Increment Counter
Users can increase the counter value by 1 through a simple function call. Each increment operation is recorded permanently on the Core DAO blockchain with the caller's address and timestamp. -
Decrement Counter
The smart contract enables users to decrease the counter value by 1, with built-in protection preventing the counter from going below zero. This demonstrates basic validation logic in smart contracts. -
Custom Increment
Advanced functionality allows users to increment the counter by any positive amount, providing flexibility while maintaining security through input validation. -
Ownership Control
The contract includes ownership mechanisms where only the deployer (owner) can reset the counter to zero, demonstrating access control patterns in smart contracts. -
Event Logging
All counter operations emit events that are permanently recorded on the blockchain, creating a complete audit trail of all interactions with the contract.
