HydroLedger Verified

HydroLedger Verified is a blockchain-based solution designed to improve transparency and trust in agricultural water usage reporting.

The platform allows users to submit irrigation-related data such as farm name, region, crop type, reporting period, water usage, and irrigated area. Before being registered, the information is transformed into a unique hash, helping guarantee integrity and proof of submission. This creates an auditable record that can be independently verified.

The MVP focuses on a simple and practical flow: the user fills out a form, the data is processed in the frontend, a hash is generated, and the record is submitted to a smart contract. A dashboard then displays the submitted reports in a clear way.

HydroLedger Verified shows how blockchain can support sustainability, accountability, and better data reliability in water management for agriculture.

HydroLedger Verified was built as a fast MVP using Scaffold-ETH 2, Next.js, React, Solidity, Hardhat, and blockchain interaction tools from the Scaffold-ETH stack.

The frontend includes a submission form where users enter irrigation data such as farm name, region, crop type, reporting period, water usage, and irrigated area. The application processes these values and generates a deterministic hash to represent the report. This hash is then sent to the smart contract and stored on-chain as proof of record integrity.

On the smart contract side, Solidity is used to register report submissions in a simple and transparent way. The project also includes a dashboard page to display submitted records and make the MVP easier to understand during the demo.

The goal was to create a clear proof of concept showing how blockchain can be used for transparent agricultural reporting under hackathon time constraints.
