AO-Database

AO-Database is a decentralized project management solution leveraging Ethereum's blockchain to ensure transparency and accountability. Team members can document their daily progress, report issues, and log any errors or failures encountered during development. Each entry is secured with an automatic timestamp, preventing tampering and providing a clear, immutable record of the project's timeline. This ensures full traceability and allows stakeholders to monitor progress in real-time, promoting accountability and better collaboration.

AO-Database is built using the Ethereum blockchain for its decentralized and tamper-proof nature. I used Solidity to write the smart contracts that power the project, ensuring that each task entry, issue, and error report is securely logged and timestamped on the blockchain. By leveraging Hardhat as the development environment, I could efficiently compile, deploy, and test the smart contracts in a controlled and flexible environment.

The backend is powered by these Solidity contracts, which automatically associate a timestamp with every task or update logged by a team member. This ensures that no one can alter or backdate the project’s progress history. The Ethereum blockchain guarantees that all data remains immutable, providing full transparency and trust among team members and stakeholders.

One of the hackier aspects of the project is using a customized task logging structure within the smart contract to optimize gas usage, ensuring that each entry is as efficient as possible on the Ethereum network. This allows for smoother interaction without incurring high transaction costs, making the solution scalable for larger teams.
