PeerFlip

PeerFlip protocol

PeerFlip is a decentralized method to simulate a coin toss among (N) participants. Except for the room server which participants use to join the same room and the STUN server that is needed for the participants to establish the initial P2P connections to each other, the protocol does not rely on any centralized party to calculate the coin flip outcome.

How to run

To run the frontend :

cd peer-flip-frontend
npm install
npm start

If you want to run the backend locally (for room management) :

Set REACT_APP_SERVER_URL to 'wss://localhost:9090' in the .env file inside peer-flip-frontend .

Then run:

cd peer-flip-backend
npm install
npx tsc *.ts 
node server.js
