Polyataraxis

A Dapp that uses Polygon & Chainlink for payment and Filecoin/IPFS for health conversation records storage

Comment 3

Inspiration

Polygon, chainlink, and IPFS/Filecoin are used a lot in NFT use cases. However, we want to prove that Polygon, chainlink, and IPFS/Filecoin can be used for many other fields such as healthcare. We think IPFS/Filecoin can be used for storing customers' health records and data while Polygon and chainlink can be used for setting wallet and payment. Thus, we would like to introduce Ataraxis.

What it does

Ataraxis is a Dapp that provides wallet set up using Polygon and chainlink. It also provides mental health diagnose and therapy. Customers can sign up for new appointments by posting comments and paying Ethereum funds through Metamask. Customers's comments are stored through Web3.Storage, making it available on IPFS with long-term backing by Filecoin.

The decentralized forum pulls forum state from a blockchain smart contract and post as well as comments from IPFS and Filecoin. The Dapp users need to provide web3.storage token ID before they can post the comment.

How we built it

We built transactions using Solidity, Hardhat, and ContentCID. We built a facade using React that ties together the contract interaction and the web3.storage so users can add posts and the posts will be stored in Web3.storage.

We deployed the contract using polygon and truffle. The wallet was built using polygon, chainlink, solidity. The Dapp was deployed using Spheron network.

All posts and comments content are stored in Filecoin and IPFS, while all ids and votes are stored in Ethereum smart contract.

Spheron

We used Spheron to build a decentralized User Interface

Technologies we used

  • IPFS/Filecoin: All posts and comments content in chat are stored in Filecoin and IPFS, while all ids and votes are stored in Ethereum smart contract.
  • Spheron: Using Spheron Application to host the Dapp UI on IPFS
  • Polygon: smart contract, we deployed the contract using polygon and truffle.
  • Chainlink: The wallet was built using polygon, chainlink, solidity.

Challenges we ran into

We had challenges to tie everything together because of bugs and errors. We also did not have enough funds to test.

Accomplishments that we're proud of

We were able to deliver the Dapp and explained out idea

What we learned

We learnt about Ethereum. We learnt to build and store data in. Web3.storage and use contentCID.

What's next for Polyataraxis

We would like to let users pay funds to upload and store their other medical records
