The problem MedBlocks solves

It is very common to see people loose their medical records and other important credential documents. They may have kept it somewhere and cannot find it or their digital copy was accidentally deleted.MedBlocks provides a complete solution for that. It is developed specifically targetting Health Records. Storing your records on Google Drive is not a safe option as it is a centralized service and can crash at any given moment.
MedBlocks leverages the power of Decentralization and Permanent Storage with the help of Smart Contracts and Filecoin.The health care center will mint your result as a NFT directly to the patient's wallet.

Challenges I ran into

I encountered various errors when trying to implement Push Protocol and Filecoin in my project. I had to go through various debugging sessions to figure out what went wrong. Honestly, most of my days were just inserting "console.log()" in various functions to find the bugs.
