Build & Run: make && ./analyzenetwork.sh
After 100+ minutes depending on system performance the script should print YES if a small-world graph has been detected. Otherwise it will crash or print NO.

README for btc-crawl follows. The btc-crawl authors wrote all the network code. I’m just piggybacking on their project and go. To save time and because I’m researching go.
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.

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.
(In approximate order of priority)
- Namespace useful sub-packages properly (outside of
main) - Fix
go build -racerace condition warnings. (Not sure if this is feasible.gologand other fundamental pieces seem to trigger warnings possibly erroneously.) - Tests would be nice.
