What tools are available to analyze the bitcoin blockchain?
I know Chainanalysis.com runs a service, but I'm not sure they would even want to help.
Are there any open source tools? Or any tools?
Arkham's visualizer would help, It is good for quick overview, but the login requirement is kidda stressful when you want to check something fatst.. And also the data is a bit limited, more visual than detailed. Here is the link in case you want to try it out:
https://intel.arkm.com/Then probably for indepth analysis, I just stick with OXT which gives more insight into clustering and transaction patterns, and BTC RPC Explorer
https://github.com/janoside/btc-rpc-explorer.. if you run your own node. These are little more technical, but once you become used to them, you’ll get more out of It…
Arkham’s visualizer is great for a quick glance but it requires a login, which can be time wasting but if u are not fast about getting the info I also will recommend Arkham’s visualizer.
@OP I also recommend you check out OXT and BTC RPC explorer for more in-depth analysis
