Proof of Work – Mining Hash Rate Distribution: Too Much Centralization?

I am researching different types of blockchains, both PoS and PoW. You can usually find important data on the former that is obviously not available on the latter. Specifically, we are looking for a dashboard that shows the hashrate distribution sorted by miner, country, and ISP, the total number of miners, and the number of miners controlling 51% of the hashrate. Similar to this data from Ethereum sources and sources.

I found the following resources: Some include country-specific hash rates and network maps, but I haven’t found a complete dashboard like other PoS projects.

This data is very important in view of the next study showing high centralization of mining and PoW consensus control.

In-Depth Analysis of Bitcoin Mining Pools

We perform the first in-depth analysis of mining reward distribution within three of the four largest Bitcoin mining pools and examine the economic relationships between the pools. Our results show that individual miners are operating in all three pools simultaneously, and that a small number of actors (less than 20) in each pool analyzed receive more than 50% of the total BTC payouts.

Blockchain analysis of the Bitcoin market

We show that Bitcoin mining capacity is highly concentrated and has been so for the past five years. The top 10% of miners control 90% and just 0.1% (about 50 miners) control almost 50% of mining capacity. Moreover, this concentration of mining power is counter-cyclical and dependent on the price of Bitcoin. It decreases when the Bitcoin price rises sharply and increases during periods when the price falls or a halving event occurs. Therefore, the risk of 51% attacks increases during this time as well.
