Consensys Academy 2018 Developer Program Final Project - Ether Flow Bounty Dapp

Description

Ether Flow is an ethereum bounty dapp used for getting answers to questions and earning money (ether) by answering questions. Questions should be answered using "flows" - lyrics, poems, or raps.

User Interface

I used the truffle react box to build the user interface. I have no front-end or web development experience so the user interface is very rudimentary and incomplete as I did not have the skills or time to acquire the skills to finish building all the front-end functionality and features that I intended. However, the solidity contract is complete and its logic is working as intended. Complete functionality of the smart contract can be tested using truffle test or by copying and pasting the EtherFlow.sol code into Remix and deleting the zeppelin library references at the beginning of the contract.
