I want to build an open protocol for building p2p apps that don't rely on any central servers. For this I'm looking into BitTorrent's DHT for discovery, libp2p for connection and encryption. The idea is that you own your identity, you pick who you trust, and nothing gets stored on servers you don't control. It will work for things like messaging, photo sharing, and private networks where you want real decentralization/federation, not just a blockchain slapped on top of the same old client server model.
