Chart shows the number of global nodes based on 1-day window size during available local export history.
Updated: ...
This page reports the estimated size of the Bitcoin peer-to-peer network including both reachable and unreachable nodes, i.e. global nodes. Unlike the low churn rate estimation method for reachable nodes (see the latest snapshot here), the method for this report can only provide a rough estimation and does not filter out potentially spurious nodes that may be gossiped by non-standard/spam/malicious peers.
Hosted btcnodes.io builds this report from addr messages returned by reachable peers. Rolling addr-message history is marked unavailable in this local deployment when those peer gossip samples are not configured.
Each chart point represents a rolling observation window. For example, the 1-day view includes addresses seen within the latest day of locally available data, and the node timestamp refers to the last peer-reported connection time.
A node that appears only briefly during the selected window can still be counted. Multiple announcements from the same IP address on different ports are treated as one estimated global node for this report, while wider windows can increase duplicate risk when addresses change.
Unreachable nodes may be outbound-only, behind NAT or firewalls, temporarily full, or still syncing. Because the crawler cannot connect to them directly, the global count remains a rough estimate rather than a confirmed reachable-node census.
