fintech_finder

This is a blockchain-based workforce hiring and payment system, using Streamlit for a user-friendly web interface. The App enables customers to instantly pay the fintech professionals whom they hire with cryptocurrency, by integrating the Ethereum blockchain network into the application. We use Python libraries/modules along with Streamlit and Ganache test blockchain provider for demonstrating the results shown below sections.

Technologies

This project leverages python 3.7 with the following packages / IDEs:

• python - is an object-oriented, interpreted, and interactive programming language.

• streamlit - Streamlit is an open-source app framework for Machine Learning and Data Science teams.

• Visual Studio Code - Visual Studio Code is a lightweight but powerful source code editor which runs on your desktop and is available for Windows, macOS and Linux.

• Ganache - A program that allows you to quickly set up a local blockchain, which you can use to test and develop smart contracts.

• BIP44 - A Python implementation for deriving hierarchical deterministic wallets from a seed phrase based on the BIP-44 standard.

• web3.py - A Python library for connecting to and performing operations on Ethereum-based blockchains. Web3.py can help you read block data, sign and send transactions, deploy and interact with contracts, and a number of other features.

• mnemonic - A Python implementation for generating a 12- or 24-word mnemonic seed phrase based on the BIP-39 standard.

Usage

To use the Fintech Finder App, clone the repository and run the above commands in gitbash as applicable,

git clone https://github.com/sidbetatester/fintech_finder.git

# 1. From your terminal, navigate to the project folder that contains your `.env` file and the `fintech_finder.py` and `crypto_wallet.py` files. Be sure to activate your Conda `dev` environment if it # is not already active.

cd fintech_finder

# 2. To launch the Streamlit application,type

streamlit run fintech_finder.py

# 3. On the resulting webpage, select a candidate that you would like to hire from the appropriate drop-down menu. Then, enter the number of hours that you would like to hire them for. (Remember, you do not have a lot of ether in your account, so you cannot hire them for long!)

# 4 Click the Send Transaction button to sign and send the transaction with your Ethereum account information. If the transaction is successfully communicated to Ganache, validated, and added to a block, a resulting transaction hash code will be written to the Streamlit application sidebar.

Note: to close Streamlit from gitbash, click ctrl + 'c'
