RSA encryption and digital signature implementation

This project is an implementation of the research article, "Analysis of the Blockchain Protocol in Asynchronous Networks" written by Rafael Pass, Lior Seeman, and Abhi Shelat, and the blockchain protocol where the program will create a blockchain with hash values, a digital signature and an actual transaction.

A light weight blockchain build with python, JavaScript, html and flask framework for frontend. Some of the components are private and public key, transaction, mine, memory pool, fee calculation, target difficulty, peer-2-peer network, broadcast blocks, resolve conflicts, UTXOS etc.
