Myriad: Democratizing Governance and Medical System

V1 (MediChain) can be found at: MediChain Repository

Myriad is a decentralized platform designed to address critical challenges in healthcare data management and governance. It empowers patients with secure control over their medical records using blockchain and gives them the ability to participate in healthcare governance through Decentralized Autonomous Organizations (DAOs). Myriad leverages decentralized storage (IPFS) and secure encryption to protect patient data, while enabling stakeholders to vote on system improvements.

This repository houses the core smart contract logic developed using Foundry.

Key Features

• Decentralized Data Management: Patients securely control access to their medical data, which is stored using IPFS with end-to-end encryption (4096-bit RSA).
• Governance with DAO: Patients, doctors, clinics, and other entities participate in a decentralized governance system to vote on proposals related to system improvements.
• Blockchain-based Voting: Weighted voting mechanisms allow for fair decision-making, ensuring transparency and accountability.
• Secure Data Sharing: Patients can share medical data with healthcare providers through encrypted QR codes, ensuring data privacy and security.

Getting Started

Prerequisites

• Install Foundry by running:

  curl -L https://foundry.paradigm.xyz | bash
  foundryup

Building the Project

To build the smart contracts, run:

forge build

Running Tests

To execute the test suite:

forge test

Deploying the Contracts

To deploy the smart contracts, use the following command with your RPC URL and private key:

forge script script/Contract.s.sol:ContractScript --rpc-url <your_rpc_url> --private-key <your_private_key>

Running a Local Test Node

You can use Anvil to spin up a local Ethereum node:

anvil

Usage and Features

•	Data Management with IPFS: Patient records are stored in encrypted form on IPFS, with hashes recorded on the blockchain.
•	DAO Governance: Myriad utilizes a Decentralized Autonomous Organization (DAO) for healthcare governance, where participants vote on system policies and improvements using weighted voting mechanisms.
•	Secure Sharing: Medical data can be securely shared using QR codes, ensuring only authorized access.
