How does Chainalysis claim to know the intent behind all of the crypto transactions they studied?

Good question! I am not sure! I had a brief look at their 2020 and 2021 report but I havent been able to see how they got the data and reached their conclusions.

Its worth noting that their entire business is built around detecting blockchain based illicit activities.

That’s interesting! I’ll search it out and see what I can find.
