The chart categorizes the total number of unique In contrast to the reachable node metrics, the unique reachable node metrics take account of some Bitcoin nodes connecting to the network using multiple network types, thereby providing a better estimate of the actual number of Bitcoin nodes. reachable A node is considered reachable when a connection to it could be established. Bitcoin nodes into categories indicating the network types Network type refers to the network protocol used to establish a connection. Network types currently taken into account are IPv4, IPv6, Tor (v3), I2P. supported by a given node.

To avoid clutter, the graph only shows network-type combinations used by more than a hundred nodes; node counts from combinations with fewer nodes are consolidated in the “other” category.
