About The Project

Blockchain being an immutable ledger and with decentralized nature has a great potential for increasing the security, privacy and efficiency of Medical Health Record keeping systems. Currently existing solutions rely on centralised database which are susceptible to Ransomware attacks, Denial of Service(DoS) attacks and also have significant counterparty risks. Some decentralized solutions are also exist but some of them are not really decentralized that are based on private or permis- sioned blockchain, while some which are based on public blockchain have not properly addressed the performance and scalability issues.

The proposed system is based on EVM compatible public blockchains using IPFS as a decentralized file storage solution and uses 2048 bit RSA encryption to encrypt the IPFS HASH of file metadata on the client-side before uploading the HASH on the blockchain. For supporting fast and complex queries this system uses a decentralized indexing protocol The Graph. The smart contract is currently deployed on Goerli Testnet.

With this system patients can access their medical records anytime anywhere without the counterparty risk from centralized entity. This system also features QR code for sharing of medical files from patients to doctors. With the proposed implementation the decentralized medical record keeping system provides increased security and privacy compared to centralized systems without loss of significant performance or scalability benefits.

Getting Started

Requirements

• git
  • You'll know you did it right if you can run git --version and you see a response like git version x.x.x
• Nodejs
  • You'll know you've installed nodejs right if you can run:
    • node --version and get an ouput like: vx.x.x
• Yarn instead of npm
  • You'll know you've installed yarn right if you can run:
    • yarn --version and get an output like: x.x.x
    • You might need to install it with npm
• Optional Instruction
  • Make sure that this repository and medichain-hardhat repository are in the same level in your directory structure.
  • This makes sure that whenever you deploy the smart contract, this repository's constants files are updated.

Quickstart

git clone https://github.com/sadityakumar9211/medichain-nextjs
cd medichain-nextjs
yarn

Optional Gitpod

If you can't or don't want to run and install locally, you can work with this repo in Gitpod. If you do this, you can skip the clone this repo part.

Locally Deploying

2. Deploy to your contract to Goerli After installing dependencies, deploy your contracts to goerli:

yarn hardhat deploy --network goerli

3. Connecting with Subgraph

You can use the same subgraph temporary URI (as present in the pages/_app.js) to query the data or you can clone this repository and deploy your own subgraph using the instructions in above repo and generate your own temporary query URI.

4. Start your UI Make sure that:

In your networkMapping.json you have an entry for PatientMedicalRecordSystem on the goerli network.

yarn dev
