Citadel Dispatch

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.

Scott, cofounder of SideSwap, joins the show to talk about what his team has been quietly building in the Liquid ecosystem. We cover SideSwap's atomic swap markets, their peg-in/peg-out service, and how partners like Aqua Wallet are plugging into their infrastructure. Scott breaks down the new Liquid Connect feature, their first Simplicity based binary outcome contracts on Swaption, and the roadmap toward Bitcoin native prediction markets on Liquid. We also get into Liquid's privacy advantages over Tron and Ethereum for Tether users, the surprising growth of the Brazilian stablecoin dePix, the federation trust model debate, and why liquid adoption has been slow but may finally be turning a corner.

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.
