To note, Figma use something inspired by but not quite CRDTs:
> Figma isn't using true CRDTs though. CRDTs are designed for decentralized systems where there is no single central authority to decide what the final state should be. There is some unavoidable performance and memory overhead with doing this. Since Figma is centralized (our server is the central authority), we can simplify our system by removing this extra overhead and benefit from a faster and leaner implementation.
> It’s also worth noting that Figma's data structure isn't a single CRDT. Instead it's inspired by multiple separate CRDTs and uses them in combination to create the final data structure that represents a Figma document.
