Contract's & Implementation

The DonorContract is a Solidity smart contract designed to manage data related to organ donation. It tracks three main categories: pledges (people promising to donate organs), donors, and patients (organ recipients).

Key Features:

1. Data Storage:

   • Stores details like name, age, gender, medical ID, blood type, organs, weight, and height for pledges, donors, and patients.

   • Uses mappings (key-value pairs) to store information and arrays to maintain lists of IDs.

2. Functions:

   • Set Data: Add details for pledges, donors, or patients (ensures no duplicate medical_id).

   • Get Data: Retrieve information by medical_id or get lists/counts of all entries.

   • Validate Data: Check if an entry exists in the system using its medical_id.

Use Case:

The contract supports a decentralized system for managing organ donation data, ensuring integrity, transparency, and easy access to information.

In My blockchain project, the front-end was developed using HTML, CSS, and JavaScript, which provided a dynamic and interactive user interface. Users could interact with the blockchain by initiating transactions and viewing updates through the front-end. This interface was designed to be user-friendly, ensuring that the blockchain operations were accessible and understandable.
