DOMINOES! Not the pizza, the game. It's really popular in my home country of the Dominican Republic. But in Europe, people don't play it so much. I could always play online with my friends back home, but that would mean trusting a centralised server to shuffle the pieces fairly, and I don't trust centralised authorities, I'm Dominican. So I decided to build a fully P2P, secure dominoes game in javascript. I'll show how I used weird cryptography, cool npm modules, and new exciting things like WebAssembly to do this.
