Historical Bitcoin full node counts Is there an online record of historical Bitcoin node counts? If so:


When did the record keeping begin?
Are IP addresses available?
Did Satoshi and most early adopters run Bitcoin nodes over Tor or were their real IP addresses revealed to other Bitcoin nodes?
Everyone that ran a node has/had the ability to record lists of other Bitcoin nodes and their IP address with a "getaddr" request (assuming they allowed incoming connections). I am not aware of a centralized online database of these records dating back more than 1 year: https://bitnodes.21.co/dashboard/?days=365
Yes: https://bitnodes.21.co/nodes/
Some early adopters used real IP addresses and others (including Satoshi) obscured their IPs with Tor, VPNs, or other means.
