Token Exchange System

About

This project was made for the subject of High Dependability Systems. It is part of the Major in Cybersecurity of the Master in Computer Science and Engineering @IST. In this project me and my group implemented a simplified version (no round changes) of the Instanbul-BFT Consensus Algorithm Protocol, which is known in the blockchain community as QBFT.

1. The Token Exchange System holds a set of accounts.
2. The servers are responsible for maintaining the set of TES accounts.
