Asynchronous consensus has been considered the most robust, yet the most system-friendly consensus in the open network. Unfortunately, previous protocols all suffer from high complexity. In this talk, we will introduce our recent sequence of progress on how to make asynchronous permissioned consensus really fast, and finally, real. Along the way, we will discuss relevant theoretical and practical challenges.
