Orbit: Blockchain Investigation Tool 

Orbit is designed to explore network of a blockchain wallet by recursively crawling through transaction history.

The data is rendered as a graph to reveal major sources, sinks and suspicious connections.

Usage

Let’s start by crawling transaction history of a wallet

python3 orbit.py -s 1AJbsFZ64EpEfS5UAjAfcUG8pH8Jn3rnOf

Crawling multiple wallets is no different.

python3 orbit.py -s 1AJbsFZ64EpEfS5UAjAfcUG8pH8Jn3rn1F,1ETBbsHPvbydW7hGWXXKXZ3pxVh3VFoMaX

Orbit fetches last 50 transactions from each wallet by default, but it can be tuned with -l option.

python3 orbit.py -s 1AJbsFZ64EpEfS5UAjAfcUG8pH8Jn3rn1F -l 100

Orbit’s default crawling depth is 3 i.e. it fetches the history of target wallet(s), crawls the newly found wallets and then crawls the wallets in the result again. The crawling depth can be increased or decresead with -d option.

python3 orbit.py -s 1AJbsFZ64EpEfS5UAjAfcUG8pH8Jn3rn1F -d 2

Wallets that have made just a couple of interactions with our target may not be important, Orbit can be told to crawl top N wallets at each level by using the -t option.

python3 orbit.py -s 1AJbsFZ64EpEfS5UAjAfcUG8pH8Jn3rn1F -t 20

If you want to use the collected data in some other way, you can save it to a JSON file by using the o option as follows

python3 orbit.py -s 1AJbsFZ64EpEfS5UAjAfcUG8pH8Jn3rn1F -o output.json

Visualization

Once the scan is complete, the graph will automatically open in your default browser. If it doesn’t open, open quark.html manually. Don’t worry if your graph looks messy like the one below or worse.

Select the Make Clusters option to form clusters using community detection algorithm. After that, you can use Color Clusters to give different colors to each community and then use Spacify option to fix overlapping nodes & edges.

As Orbit uses Quark to render the graph, more information about the various features and controls is available in Quark’s README.
