The problem Med_ETH solves

Med_ETH tackles a multitude of problem by incorporating the Web3 element. By using IPFS, no one entity/hospital has rights access to your medical data. You are the owner and you choose who to share it with. IPFS also provides an all-in-on medical card incentive layer: your wallet stores all your medical credentials and records and shrugs away the need to carry physical documents with you everywhere. And even if you don't have your docs with you, just signing into your wallet at any hospital allows the medical staff to gain access to your data.

Suppose you want to disclose sensitive data without actually disclosing it? This is where zk-SNARKs come in, a novel technology that we are experimenting on (future scope) where patients can prove to the doctor that they have so-and-so problems without revealing the diagnosis of the problems itself.

In the near future, if we are successful we plan to shift Med_ETH to its own blockchain platform (eg: MedChain) using HyperLedger Fabric, which offers proprietary blockchain services.

Challenges we ran into

Our backend was mostly Solidity smart contracts and IPFS technology. Our fronted had some hitches, such as the .jsx files not displaying the site properly. The most anxious part was linking backend with frontend, which we got over in a couple hours. We are happy to say, the site is up and running quite well. The only dependency required by users is to install Metamask extension in their browser.
