uuidv8 does not contain a timestamp or counter unless you put them in there, it only contains a version and variant field. It's a very broad format that lets you contain whatever bits you want.

This library converts a uuidv7 into a cryptographically random but deterministic uuidv4 recoverable with a shared key. For all intents and purposes the external view is a uuidv4, the internal representation is a v7, which has better index block locality and orderability.
