Bitnodes is currently being developed to estimate the size of the Bitcoin network by finding all the reachable nodes in the network.
Top 10 countries with their respective number of reachable nodes are as follow.
Map shows concentration of reachable Bitcoin nodes found in countries around the world.
Be part of the Bitcoin network by running a Bitcoin full node, e.g.Bitcoin Core.
Use this tool to check if your Bitcoin client is currently accepting incoming connections from other nodes. Port must be between 1024 and 65535.
Start a Bitcoin full node on your Linux, Mac, BSD or Windows system to help validate and relay transactions across the Bitcoin network by running this command:
Bitnodes is currently being developed to estimate the size of the Bitcoin network by finding all the reachable nodes in the network. The current methodology involves sendinggetaddrmessages recursively to find all the reachable nodes in the network, starting from a set of seed nodes. Bitnodes uses Bitcoin protocol version 70001 (i.e.>
= /Satoshi:0.8.x/), so nodes running an older protocol version will be skipped. The crawler implementation in Python is available fromGitHub (ayeowch/bitnodes)and the crawler deployment is documented inProvisioning Bitcoin Network Crawler.
The crawler maintained by Bitnodes connects from these IP addresses:184.108.40.206,220.127.116.11,2a01:4f8:10a:37ee::2
