Own measurement over observed user agents. Counts only active signaling (UASF-BIP110 / bip110-v*); excludes BIP110-Theory mentions and the historical UASF-SegWit-BIP148 from 2017. Node software signaling — not miner block signaling, which is a separate metric.
Select versions above to plot their share over time. Useful for watching a new release propagate while older ones decay. The global date range applies here too.
Observed nodes by implementation, one point per day.
Percentage of observed nodes running each implementation.
Core nodes running releases at least three major versions behind the newest (or 0.x).
Different crawlers see the network differently (coverage and methodology). Every node count is an observation, not a census.
Observed network size reconstructed from Internet Archive captures (bitnodes.21.co and earn.com eras), a dataset that had become inaccessible.
This page is the telemetry layer. The synthetic-network side of the project is under active development — listed honestly above rather than implied.
