- The document discusses Fluence Labs' Hack The System workshop which teaches how to build peer-to-peer (P2P) applications and distributed systems using their open source stack. - Their stack includes Aquamarine, a programming language for building P2P networks, and microservices that can be composed with Aquamarine and WebAssembly. This allows developers to build applications like chats, games, blockchain oracles, and community-run apps. - The workshop provides an introduction to their intermediary representation (AIR) which allows calling functions on remote peers, as well as bounties for using AIR and building applications with their Fluence stack.
