Looks great. I use some CRDTs like Loro and Automerge, are there any learnings or collaboration you're taking from them to improve DeltaDB?

Also the name, I thought it was a database with CRDTs due to the "DB" at the end of DeltaDB, but it's a version control system, I thought that was somewhat misleading, any reason why it's named so?

Oh is this based on my favoritest data structure ever: zed's Sum Tree?

Is this / will this be open source? I have a direct immediate need for this and was about to break ground on greenfield implementation. Had no idea Zed was working on something similar. I would of course much rather collaborate than maintain a competing VCS.
