The Messaging App With No User IDs (SimpleX Interview)
Show notes
SimpleX Chat is the only messaging network where users have no identifiers—no phone numbers, no usernames, no user IDs at all. Henry interviewed founder Evgeny Poberezkin about how unidirectional message pipes create a network where servers don't even know users exist, why this isn't federation, how it compares to Signal and Session, and why the company is based in the UK despite encryption battles.
