Is anyone willing to help me?

Beautiful map.

I think we have a nice geographical decentralization of bitcoin nodes. We don`t have as much nodes in developing countries because fewer people can afford one there.

But developed countries have nice distribution.

More than half of the nodes are onion nodes, so in terms of clearnet decentralization, not so much.

If you check the ASNs that the nodes are on, you will find that the overwhelming majority are datacenter related. There isn't a lot of people running it at home or on a different network which still introduces a centralized point of failure to some degree.

Unfortunately i couldn't find data or discussion about node count from about decade ago. But according to Luke's data[1], on 2018 there was peak ~205K total node count and ~23K total listening node count.

Ah fair enough, I remember seeing this sometime ago.

I think the disparity is pretty big as compared to the other statistics that you find around and the accuracy can be quite skewed, even today (4k vs 6.4k). That is taking into account that you're only looking at the listening nodes. Anyhow, he has never shared the methodology and the last time I checked, he preferred to keep it a secret so I can't really vouch or check for the accuracy.

Let's assume there are 10k active full nodes, and 85 percent of these nodes are concentrated in one country. What is the implication?

• Will it mean any form of centralization?
• I think the major concern should be if the government of that country rises against bitcoin mining

Centralization and redundancy goes hand in hand. If for some reason, a certain country experiences a natural disaster or any form of attack that disrupts the internet connection, electricity, etc. You would see a pretty big drop in node count. It wouldn't pose as a critical threat but it is certainly not what we want.

Bitcoin mining and running a Bitcoin node is quite different. Latter is harder to crackdown.

Noted, but in the case of redundancy, the glory would be in the pass because at present, it might not be in use. I understand we should only be afraid of attacks or natural disaster if the nodes are concentrated in one region. So, this has nothing to do with centralization in terms of decision making.

Thank you bitmover for this pictorial highlight. It shows that node operators are evenly distributed across the world. Maybe it is not time for Africa yet, because there is relative small number of node operators compared to the size of the continent.
