Counting Feathercoin Full nodes
-
Does anyone know how the charts that list nodes on the network do it?
I’m assuming they are fed information from a number of nodes around in different geographic locations, as one node can’t see all other nodes.
Is it as simple as that having a number of nodes around the world that just collect peer information and feed it back somewhere to collate it all?
Or am I missing something somewhere and its done a different way?
I’m asking as the only node count website I’m aware of for FTC seems very slow in updating for Australia, and wonder if this is something we could do as a group project if a number of us around the world are running full nodes to be able to provide this information back to make a more accurate map of Feathercoin nodes around the world.

This is what I found:
Bitnodes is currently being developed to estimate the size of the Bitcoin network by finding all the reachable nodes in the network. The current methodology involves sending getaddr messages recursively to find all the reachable nodes in the network, starting from a set of seed nodes. Bitnodes uses Bitcoin protocol version 70001 (i.e. >= /Satoshi:0.8.x/), so nodes running an older protocol version will be skipped.

So it grows out like tree branches, by getting local peers, then asking them for their peers and so on.
A bit over my current skill level, but something to file away for the future

I have four full nodes online :)

Well done!
I’ve got two at the moment, but that is just because I’m using the second one to test some stuff, will cut it back to one later tonight as I don’t see any great benefit of having two nodes sitting next to each other.
