The problem HealthChain solves
HealthChain is a decentralized healthcare application built on blockchain technology that enables secure management and sharing of medical records. HealthChain application addresses several critical issues in the healthcare sector:
- Data Privacy and Security: Traditional healthcare systems often store sensitive medical records in centralized databases, which can be vulnerable to hacking or unauthorized access. HealthChain uses blockchain technology to securely store and manage medical data.
- Mismatched Medical Records: Currently, patients may have medical records scattered across different healthcare providers, which can lead to incomplete or inaccurate medical histories. HealthChain enables patients to consolidate their entire medical record in one decentralized application.
- Access Control and Management: Managing who can access medical records is often cumbersome in traditional healthcare systems. HealthChain allows patients to easily grant or revoke access for doctors, ensuring that only trusted healthcare providers have access to sensitive data.
Why HealthChain?
We believe that your data is your control. We are empowering patients with easy record management. Patients can add, update, and manage their medical records directly, reducing reliance on healthcare providers. Medical records are stored in a decentralized manner, preserving a history of updates without overwriting previous data.
HealthChain also improves in the healthcare provider side by improving efficiency. Doctors can access a patient’s comprehensive medical history without needing to retrieve records from multiple healthcare institutions, saving time and improving diagnostic accuracy.
Lastly, by using blockchain technology, all medical records, documents, and access logs are securely stored. The decentralized nature of blockchain ensures that data is resistant to tampering and unauthorized access.
Challenges we ran into
- Metamask Error:
While integrating MetaMask into the project, our team encountered the "RPC Error: Internal JSON-RPC error". This error is faced by many developers and occurs when there is an issue with the communication between the MetaMask extension and the Ethereum network or the smart contract. It is basically the MetaMask extension is configured to use an unsupported or incorrect network. If the RPC provider URL or network ID is incorrect, it can cause the "Internal JSON-RPC error."
The solution is to ensure that MetaMask is connected to the correct network that matches your contract’s deployment. We have to manually add or switch to the appropriate network by going to MetaMask settings and selecting the "Networks" tab.
- Smart Contract Deployment Error.
Creating Smart Contract in RemixIDE were no issues as the deployment and compilation were correct. But when integrating with the client side, there were many issues. We realised it was the deployment error. Errors during smart contract deployment can occur if the contract is too large or has issues with its constructor. Furthermore, compilation errors in the Solidity code can occur due to incompatible versions or improper syntax.
The solution is to ensure the constructor doesn't perform complex logic that could fail in deployment. We also had to use the older version of Hardhat to ensure deployment works.
