What it does

Blockchain based Application to track the results of people testing for Covid 19

How I built it

It is built with Angular, NodeJS, Solidity Smart Contract, and Android. Blockchain network is Ethereum blockchain Rinkeby testnet.

Challenges I ran into

  • Working remotely with different timezone
  • Integrating web3 with angular and calling smart contract functions

Accomplishments that I'm proud of

  • Working remotely with different timezone.
  • write about smart contracts
  • Managed to actually use Angular to call smart contract using web3 to post data onto blockchain, which is the most important part of the application.
  • Working in collaboration and keeping up the sync
  • Its hard to get pieces working made by different persons

What I learned

  • Blockchain technologies
  • Create UI frames in 1 hour from scratch
  • You can learn and work without even meeting people

What's next for block-app

To Make it scalable for other pandemic situations
