Blockchain Credential Asserting Tool

To develop a way to verify credentials in a consistent and irrefutable manner, my team and I turned to the immutable and decentralized  blockchain. This technology is used in order to have all blocks agree in the validity of the credentials, while removing the ability to alter of remove the diploma credential. For the scope of this project, we wanted to focus on graduation diplomas for students at OSU.

Ganache is the local blockchain technology that we developed with, Truffle deploys the smart contracts that are used to allow for admins to make these diploma credentials, and Metamask was the cryptocurrency wallet that we used to emulate the ability to send verification transactions through Ganache.

Initially, I was tasked with configuring Metamask and Ganache in order to have local transaction using fake currency throughout the development and final deployment of the project. I worked on the development and testing of the smart contracts using Solidity, as well as the design of the checkDiploma page. Finally I worked on the development of the front-end JavaScript, which used Web3 to interact with ganache and facilitated the verification transactions on the blockchain.

The result of this project was 3rd Place overall in the Hackathon and a new-found passion in blockchain technologies. I hope to work on a similar project again in the future, so that I may learn even more about the capabilities of Blockchain infrastructure.
