Docthereum 🩺

A dapp to maintain anonymous medical reports and aids in seamless healthcare across the globe 🌎.

The problem it solves

1. Storage πŸ“‚

The traditional method of keeping records that are followed in most hospitals across India is the manual method involving papers and books. There are serious limitations of manual record-keeping including the need for large storage areas and difficulties in the retrieval of records. And the possibility of easy manipulation without detection is a serious concern.

Docthereum stores records over a decentralized network and records cannot be tampered with.

2. Anonymity 🎭

Another major concern is maintaining the confidentiality of the patient records as the patient can hold the doctor and the hospital negligent for breaking the confidentiality of his medical records

We maintain the records linked to patients' Ethereum's public address, hence providing anonymity to the patient. And the identity of the patient remains confidential.

3. Research πŸ‘©β€πŸ”¬

The research includes increased efforts to use stored medical records as a source of data for health services, epidemiologic, and clinical studies. Given that it can be cumbersome, if not impossible, to find and seek consent from patients whose current or past records might be used.

Since, we maintain our reports anonymously, and they cant be traced back to the patient himself, they can be provided to researchers to aid in their studies.

4. Decentralized Voting to allot funds to a cause πŸ’°

People who contribute to a cause with good intentions always have concerns about the transparency regarding if their money is being utilized correctly or not when there is a centralized authority controlling all the funds. People also don't get a say in it too many times.

In Docthereum we have built a Decentralized autonomous organization where funds can be utilized by Decentralised voting and everyone who's a member gets a say in it. You can become part of Docthereum DAO just by Minting a free NFT inside the app.

Challenges we ran into

1. Verification πŸ•΅οΈβ€β™‚οΈ

We had a big problem with how to verify the Doctors and labs without the need of including a 3rd party and at the same time make the process as seamless as possible.

Solution :-

We ask doctors or labs for their registration id, which we then use to verify them against an API that verifies them. Using Chainlink, we were able to integrate this functionality into our smart contract, thus making the verification process seamless

2. Different testnets

While developing the dapp, we noticed that Chainlink's rinkeby network was in maintenance and we would have to use Kovan network. But soon we realized that the subgraph we were building for the dapp doesn't support deploying on Kovan network currently.

Solution :-

We decided to make two instances of the project and deploy the smart contract on both
Rinkeby 0xa6a11dF4FAc5c4b148bC91f03FD0919237d16801
And Kovan 0x6DdD958591974891eD4819cDF9a269DaEc3C55A7.
So we were able to test the verification functionality on Kovan, all while deploying the subgraph on Rinkeby to index the Rinkeby version of the smart contract.

Note:- currently the dapp calls the instance deployed on the Rinkeby network.

Technologies we used
