I am researching the different types of blockchains both PoS and PoW. In general, I can find important data for the former that is apparently not available for the latter. Specifically, I am looking for a dashboard that shows the distribution of hash rate sorted by miner, by country, by ISP and so on, the total number of miners, how many miners control 51% of the hash rate.
You can't find such data because a lot of miners join mining pools, so for example the readily available data is that the Hash rate is sorted according to the pools rather than individual miners. The same applies to location of miner.
A miner from Russia can use the same pool as a miner from the US. How are you going to group them if the pool won't reveal that information to the public.
Remember the crack-down of miners in China? I am pretty sure some solo miners definitely use VPN. So again the information is going to be unreliable
