The problem Medicare Chain solves

With the advancement of technology and medical science, not every patient can afford the costly medical facilities.
According to a CarePayment Research Survey, it was quite clearly found that almost 64% of all the patients in America either avoids or delays any medical care because of the high cost.

And these statistics remain the same or even worse for many other underdeveloped countries.
While the insurance and donations do help patients to get the best possible medical facility, there still lies an enormously large chain of Middlemen, central authorities as well as third parties at multiple levels in this procedure.

This is exactly where Medicare Chain enters.

If observed carefully, it can quite clearly be seen that the major hurdle that prevents the patients to be in control of the complete insurance or donation amount is the long list of third parties as well as the central authorities in control.
And that is exactly the two major issues that Medicare Chain effectively solves.

First of all, this is a decentralized application and therefore eradicates any control of central authorities over the medical funds or donation amounts. This ensures the utmost security from any tamper with medical data that might take place in traditional systems.

Secondly, Medicare Chain implements a smart contract.
This contract not only operates independently but also keeps an immutable record of the participants withdrawing or donating funds while maintaining a control system that limits the accessibility of participants in the network from certain features.
Thus, smart contract in Medicare chain ensures reliability and trust in the system since there is no chance of any mishaps with medical funds due to Human bias. 

Finally, each and every transaction that takes place on this application, along with its timestamp, is stored with utmost safety on the Blockchain. Thus ensuring complete immutability of the data.

Challenges I ran into

1. Since I am using both web3.js and web3.py, the challenge was to get both of them to work simultaneously and effectively.
2. The solidity code involves some major transaction of funds from doctor to patient and admin to patient. This part was initally hard to crack but was solved later.
3. I have integrated IPFS in this application. Setting it up and uploading documents on the IPFS was also one of the challenges that I overcame.
