2 days ago, I started developing my P2P messenger. I made the first version of the protocol on paper. In the project, the connection algorithm is based on STUN and Singaling servers. The UDP hole punching method is used to bypass NAT. Today I started writing the first version of the database schema for the Signaling server. Let’s see what happens next. I’m really excited about this idea!
