Description:

The dataset hosted on this website contains the information that our crawler, Crawleth, gathered on the Ethereum peer-to-peer network during the period from September 1 to September 30, 2021. All the IP addresses have been anonymized using a salted SHA256 hash and the last byte of the address is set to 0.

All the files in the dataset are JSON files with the same format.

• "stats" is the object containing general information about the current crawl
  • "aggregated_crawls": number of crawls that are aggregated in this file
  • "original_filenames": name of the aggregated files (date is UTC+0)
  • "up_count": number of online nodes gathered
• "up" is the list of nodes gathered by Crawleth. There are several nested objects
  • "IP address": is a list [hash of the IP address, IP address which last byte is set to 0]
  • "UDP port"
  • "Seen node IDs": a list of seen NodeID for this IP-port association
  • "as": Autonomous System Organization
  • "asn": Autonomous System Number
  • "city"
