It&#x27;s a technology for allowing money to bypass the rule of law. By design it concentrates power in the hands of property owners, and allows them to undercut democratic rules against activities with negative externalities - and since it&#x27;s more expensive than currency, those are the only use cases that make sense; prime use cases would be things like drugs, smuggling, tax evasion, child porn, terrorism. I think IED control software is a pretty fair comparison actually, except that IEDs are somewhat more democratic.
