John Carvalho is the synonym guy too.
He came on TFTC and Guy's pod. I only listened to the TFTC appearance though, and thought, I don't really care about the project or really like Carvalho, but their graph schema is probably interesting.
Discussion
I’ve listened to one or two of these podcasts with John. I like a lot of his ideas, I think he correctly identifies a lot of problems and correctly identifies many of the tools we need to solve those problems. But what exactly he wants to do with those tools was always too vague.
Maybe his vision is coming more into focus. Looks like the products are getting fleshed out. But is anyone actually using pubky?
