Project: A Notary Dapp

This is a brief post about my final project for Consensys Academy Blockchain Developer Bootcamp 2019-2020.

What did I build?

I built a Notary/Proof of Existence DApp that works on Rinkeby and another app that works on Ganache. I will be discussing the Rinkeby version.

Demo?

App Demo: http://bit.ly/36DWMbW
Requires: MetaMask & Internet Connection & Rinkeby ETH

Rinkeby contract deployed: https://rinkeby.etherscan.io/address/0x5b0c51dDA0263bBffEb3093D7F664305FB075e08/

'notary-dapp-rinkeby'

What does this project do?

It allows users to upload a file to IPFS and notarize it with their MetaMask Rinkeby Ethereum Account and post it on Rinkeby Testnet with the simple click of a single deploy button. Complete with toast messages for user status updates.

How do I set it up locally?

Pre-Requisites

Required: MetaMask, Node.js, Npm/yarn, Internet Connection (for Contract Deployment and IPFS Upload)
Optional: Truffle (only for debugging and deploying smart contracts included)
