I should clarify. I'm talking about the distribution of SP, not the technical design. Hopefully Steemit will dump enough stake that it will become increasingly decentralized, but so far I think Steemit has maintained about 40-45% or more. That data is a bit stale, as I grabbed it poking around Steemsql a week or two ago.
If anyone has a convenient site up to watch SP percentages of top accounts I haven't found it yet.
here you go https://steemwhales.com/
Looks like it's out of date. Do you know who runs the site?
that's the most detailed site on steem blockchain. I don't remember having seen any that came that close to the level of information you see there.
I see it is a few months old. I figured out @heimindanger was the creator (he is doing dtube too). I just left him a comment.
