Bitnodes is currently being developed to estimate the size of the Bitcoin network by finding all the reachable nodes in the network.
Available nodes during the last 24 hours.
Chart shows the number of reachable nodes seen by the crawler in a new snapshot without taking into account the nodes that are already connected to the crawler. Reachable nodes that have reached their max. allowed connections will not be reflected in this metric.
Nodes distribution across the leading user agents.
Nodes distribution across the leading countries.
Nodes distribution across the leading block heights.
Index 0 denotes nodes with the latest block height. Index 1 denotes nodes with 1 block behind the latest block height. Latest block height is determined based on the most common block height among the reachable nodes in the network.
Time taken in milliseconds to propagate new transactions across the network.
Chart shows propagation time for transactions during the last 24 hours. Tx 50% denotes 50% of the inv messages for all transactions in a block were observed within the given time from the first 1000 nodes. Timestamp for an inv message is based on the time when the kernel first saw the packet containing the inv message. The aggregated data does not include inv messages that were observed 3 hours after the first inv message for the same transaction.
Time taken in milliseconds to propagate new blocks across the network.
Chart shows propagation time for blocks during the last 24 hours. Block 50% denotes 50% of the inv messages for a block were observed within the given time from the first 1000 nodes. Timestamp for an inv message is based on the time when the kernel first saw the packet containing the inv message. The aggregated data does not include inv messages that were observed 3 hours after the first inv message for the same block.
Be part of the Bitcoin network by running a full Bitcoin node, e.g. Bitcoin Core.
Use this tool to check if your Bitcoin client is currently accepting incoming connections from other nodes.
