OCapN (Object Capability Network) is a secure messaging protocol designed for the next generation of distributed applications. It leverages the capability security model (if you don't have it, you can't use it) to provide secure, peer-to-peer functionality with ergonomics that resemble ordinary programming. It has a rich set of features including promise pipelining, network transport agnosticism, error handling across networks, distributed acyclic garbage collection, and third-party handoffs providing powerful ways to share references with any peer. This talk will provide a tour of the protocol and show how it makes distributed, peer-to-peer development easier.
