alt Hacker NewsCan't anyone basically sanction entire wallets, and mark them, and make some legislation that any transaction involving coins originating from those wallets be rejected by all payment processors and exchanges in regulated markets?
I mean, they obviously can, but probably they have elected not to do so. But if crypto becomes a tool in the hands of enemy nation states, such regulation can't be soo far off.
Though that would create a secondary market for these 'tainted' coins, and would probably have far-reaching consequences into the crypto ecosystem.

You can't track individual coins, so you'd have to "taint" entire wallets. Using a mixer would taint the mixer and every wallet it sent to. I'd think this would end up tainting almost everything before too long.
Bitcoin also doesn't require the receiver to authorize a transaction, so if you had control of a tainted wallet, you could taint other wallets at will, wielding it like a weapon.
Doesn't seem feasible. Not that this always stops legislators.
OFAC already sanctions crypto wallets. https://ofac.treasury.gov/faqs/594
