@justindrake asked me why we don't use DA layers instead of Snapchain. I've heard the question a few times, so here's the answer. 

Snapchain is a storage layer for Farcaster data. Every like, cast, reaction you post is stored there and propagated to all apps in real time.

Social data tends to mutate often. People like things and then unlike them all the time. They also exceed rate or storage limits and their older content needs to be cleared out. 

Snapchain's main innovation is handling this in a very performant way so that the bytes on disk and over the network are minimized. This is what makes Farcaster scalable
