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. Something similar to this data from Ethereum source and source.
I found the following resources, some contain hash rates by country and the network map, but I did not find a complete dashboard like other PoS projects.
This data is very important in the light of the following research that shows the high centralisation of mining and thus of control of PoW consensus.
A Deep Dive into Bitcoin Mining Pools
we conduct the first in-depth analysis of mining reward distribution within three of the four largest Bitcoin mining pools and examine their cross-pool economic relationships. Our results suggest that individual miners are simultaneously operating across all three pools and that in each analyzed pool a small number of actors (≤ 20) receives over 50% of all BTC payouts.
Blockchain Analysis of the Bitcoin Market
We show that the Bitcoin mining capacity is highly concentrated and has been for the last five years. The top 10% of miners control 90% and just 0.1% (about 50 miners) control close to 50% of mining capacity. Furthermore, this concentration of mining capacity is counter cyclical and varies with the Bitcoin price. It decreases following sharp increases in the Bitcoin price and increases in periods when the price drops or when there are halving events. Thus, the risk of a 51% attack increases in these times as well.
Thank you
