The number of bitcoin nodes increased from 10,000 to 15,000 over the year. The fastest growing segment was bitcoin nodes launched through the anonymous TOR (The Onion Router) network.
As of February 26, 2022, the number of bitcoin nodes reached 15266. More than half of them (53%, or 8091) are bitcoin nodes with routing through the anonymous TOR network. A year ago, the share of such nodes was 19%, and their number slightly exceeded 1923. At the beginning of 2020, anonymous bitcoin nodes made up just over 2%.
In parallel, there is a downward trend in the use of IPv4 and IPv6. This indicates that users of the Bitcoin network are moving en masse to TOR.
The United States (12.7%) and Germany (11.4%) remain the leaders by the number of bitcoin nodes. But this data does not take into account bitcoin nodes with an obscure location, which is associated with the use of routing through TOR.
In January 2021, the number of available bitcoin nodes using the TOR network dropped dramatically. This was caused by a network outage due to an implementation error in the v3 onion service, apparently caused by a hacker attack. It took a little less than a week to fix the bug.
