This week Anna chats with Ismail Khoffi from Celestia about how and why they’re focusing on building a data availability-first L1 blockchain. Ismail takes us through how data availability can be a problem, primarily with light clients and breaks down the components necessary to understanding the data availability problem such as state changes, the separation of consensus from execution and how Celestia aims to be a pluggable consensus layer.
