Alright, do you mean concentration in hash rate (mining)?
don't recall, it covered both bitcoin and etherium and investigated who owned what. ill see if i can't find it.
edit: this seems to be the academic version of it, but theres a prettier journalism version with more stories and pictures: https://arxiv.org/abs/2206.02871
in this case i seem to have misremembered owners vs miners, but I'll keep poking around. this one is also older than i remember.
That is super interesting! But yeah, that was really early days. Hash rate centralisation could of course still be a problem today but it was most likely 100 times worse in 2011.
