btc-crawl
Bitcoin node network crawler (written in golang).
This is a for-fun project to explore the Bitcoin protocol and network.
Current status:
- JSON streaming is in place, and graceful shutdown.
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 --help
...
$ 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. Each node returns around ~2,500 known nodes, but usually only several have timestamps within the last hour.
Todo
(In approximate order of priority)
- Apply peer-age filter to results
- Output using some space-conscious format. Right now the output file grows fairly quickly.
- Namespace useful sub-packages properly (outside of
main)
