btc-crawl

Bitcoin node network crawler (written in golang).

This is a for-fun project to explore the Bitcoin protocol and network.

Current status:

  • It crawls with all kinds of nice parameters but stores everything in memory until dumping a giant JSON blob at the end.
  • It crawls from hard-coded values and spits a bunch of stuff to stdout.

Usage

$ go get github.com/shazow/btc-crawl
$ btc-crawl --concurrency 100 --output btc-crawl.json --verbose
...

Estimated crawl time: Unknown.

There should be under 10,000 active network nodes at any given time, according to (bitnodes.io)[https://getaddr.bitnodes.io/]. Each node returns around ~2,500 known nodes, but usually only several have timestamps within the last hour.

Todo

(In approximate order of priority)

  • Add some sensible non-verbose output
  • Apply peer-age filter to results
  • Stream JSON rather than accumulate into a giant array.
  • Add timeout option.
  • Graceful cleanup on Ctrl+C
  • Namespace packages properly (outside of main)
