Description:

The dataset hosted on this website contains the information our crawler gathered on the Bitcoin peer-to-peer network during the period from February 7 to March 3, 2020 as well as two additionnal days, June 7 and July 9, 2020. All the IP addresses have been anonymized using a salted SHA256 hash and the last byte of the address is set to 0 (the last two bytes for IPv6 addresses).

The dataset is divided in two parts contained in the crawl and export directories.

Crawl directory:

This directory contains the information gathered periodically by the crawler. There are three types of file:

• "date.json" is the type of file that contains the IPv4 nodes discovered by the crawler (format "ip, port, services, height")
• "nodes_per_getADDR_date.csv" is the type of file that contains the number of nodes answered to a GETADDR request in a crawl (format "ip, number of nodes in response")
• "up_nodes_per_seconds_date.csv" contains the number of new nodes discovered throughout a crawl

There is a fourth type of files for the crawls issued on June 7 and July 9, 2020. It is named "nodes_per_getADDR_date.pickle.bz2. These are JSON files that are encoded into into the pickle format and compressed. It contains the information (ip, port, services) about the nodes gathered from the GETADDR requests during a crawl."

Export directory:

This directory contains JSON files that gather the information about the nodes tagged as reachable (public) by the crawler. The information exported are : ip address, port, protocol version, user agent, connected since, services, height, hostname, city, country code, latitude, longitude, timezone, ASN, organization name.

Acknowledgment:

This dataset is part of a project that has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 830927.
