    CD193: FIPS - FIXING THE INTERNET

    FIPS is an open source mesh networking project that enables devices to connect directly to each other without relying on any central servers or infrastructure. Today's internet depends on companies and governments that can monitor, censor, or shut down communication at will. FIPS solves this by giving every node a cryptographic identity and encrypting all traffic automatically, so no one in the middle can see or block what you're doing. Nodes discover each other and route messages through the mesh on their own, and regular apps like browsers and SSH clients work on top of it without any special setup.
