Signed actions versus deniability trade-offs

Evgeny is the founder of SimpleX Chat, a private and secure comms protocol that has a radically different approach to the concept of user identity.  We discuss how SimpleX's unique transport network assigns addresses to connections instead of endpoints, why MLS is flawed, the upcoming scalable channels feature to compete with Telegram, and how the network plans to sustain itself through a model where large channels fund infrastructure. No phone numbers.  Private and secure. Open and scalable.
