DoxxNet founder Barrett Lyon is building a private mesh network for direct calls, chat, and 20 GB file transfers.
DoxxNet founder Barrett Lyon tells a16z’s Joel de la Garza that today’s internet has stagnated around centralized services, surveillance, and censorship. He describes DoxxNet as a parallel mesh network with 196 private domains, where users can connect directly for encrypted calls, chat, and file transfers up to 20 GB without routing through an application server. Lyon argues that VPNs solve only the IP-address problem, especially when providers lease infrastructure they do not control. DoxxNet owns its hardware and runs its AI systems locally; a team of 12 operates 26 sites without network or system administrators. The conversation also challenges claims about data-center water use and discusses how ad trackers can infer intimate life details. Lyon recounts building Prolexic to defend businesses from DDoS attacks, mapping the internet in his Opte art project, now in MoMA’s collection, and confronting Russian cybercriminals.
