Ethereum P2P network study
Dataset Overview


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"
    • "country"
    • "country_code"
    • "latitude"
    • "longitude"


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.
