> vitalik didn't credit him in his article

You mean this article?

> Verkle trees are still a new idea; they were first introduced by John Kuszmaul in this paper from 2018[link to [0]],

I want to highlight the fact that the quote from Vitalik’s article is the first sentence of the second paragraph. Credit is prominently given, not buried in any way.

Oh, I wonder if he edited it, I googled it to find what the GP was talking about and saw this which claimed he didn't: https://news.ycombinator.com/item?id=27557503

Thanks! I actually wasn't aware of the intellectual history. I added a link to your paper at the start of my post.
