Look inside

In this liveProject, you’ll use cryptography to create a fair and secure coin tossing application. This simple-sounding task is surprisingly complex, and so you’ll implement a multi-step classical protocol to create a coin flipper where neither player can cheat or bias the result. You’ll use Rust to implement the computational steps of a coin toss construction, as this powerful low-level language has great features for cryptography.

This project is designed for learning purposes and is not a complete, production-ready application or solution.
