I think your research needs to focus on money laundering, specifically fei chien or hawala underground banking. They've been doing that for centuries, so they are the Old World pros. Lots of useful information out there on the clearnet. I say that, because most times you shouldn't re-invent the wheel, you re-discover an already existing technique and then update it with modern tech.Best of LuckPineProtip: AML laws in the USA are *unbelievably draconian*. You can't so much as receive > 10k from an unknown source. i.e. anonymity itself is illegal. Also, if it can be shown that you 'intended' to be anonymous by concealing the source of funds, no matter if it's $0.01 or $100 million, then you are breaking the law. And they take all your stuff if you can be shown to be connected to money laundering, even if that stuff came from completely legitimate sources. I'm not a lawyer, so I can't say for sure how much of this is true, but the wiki page seems to support what I've heard.
