What is a v7 UUID. Why do we need more than 1. uuid from a random seed and 2. one derived from that and a timestamp (orderable)

It comes off as a low-effort question that seems to try to evoke a reply from a peer, while it's the kind of question that is best answered by an LLM, Google, or Wikipedia.

Well, a LLM could answer it or write total bullshit. But yes, Wikipedia or other research quick internet research will help generally. And excactly here, it will tell you that there are competing standards since we have competing use cases.

For simple questions like this with unambiguous answers, it is statistically very unlikely that you'll get a bullshit answer from an LLM.
