The problem Vcare- Secured decentralized medical record system solves

The number of ransomware attacks on healthcare organizations has increased by 94% from 2021 to 2022, according to a report from the cybersecurity firm , More than two-thirds of healthcare organizations in the US said they had experienced a ransomware attack in 2021, the study said, up from 34% in 2020. Hence Vcare is a blockchain and web based system which inhibits the tampering of medical reports. This also eliminates the manipulation of transactions and gives an easy access of medical reports for the hospitals.
With this system patients can access their medical records anytime anywhere without the counterparty risk from centralized entity. With the proposed implementation the decentralized medical record keeping system provides increased security and privacy compared to centralized systems without the loss of significant performance or scalability benefits.
Also the website which we have built has a user friendly UI in which the user can enter the private key of the blockchain to add in new reports. The doctor can see the patients reports by using the public key from anywhere on the globe but can never manipulate it. All the patients data is stored in a BlockChain. BlockChain is preferred over DataBase as BlockChain is tamper proof. In a BlockChain, once data is written, it cannot be modified or tampered like transactions cannot be manipulated. Another advantage is that the patient and doctor can access the data from anywhere on the globe, even if the doctor and patient do not meet each other.
Also we have used Inter planetary file system (IPFS) for storing the medical data.
One of the main advantage of our solution is that it utilizes the unused hard disk space of users across the world to store files.
And this decentralized infrastructure is an alternative to centralized cloud storage and can solve many problems found in a centralized system such as cybercrimes and thefts.

Challenges we ran into

1. The main challenge which we faced while developing the solution was the connection of our ethereum (hardhat) based blockchain backend with our react frontend . It was a difficult task to find the perfect version of moralis which could connect our blockchain to react frontend. We solved it by completely uninstalling the moralis from the package-lock.json file and again installing it in the project directory.
2. Deploying our smart contracts that is the ethereum to rinkeby and solana , and we could finally deploy the hardhat by the following command
   yarn hardhat deploy --network hardhat
