Perhaps I am misunderstanding how tracking coins typically happens, but if "tainting" the coins effectively prohibits the actors from withdrawing at their perceived value, how would this work if the actor decided to send the vast majority coins to many random, arbitrary accounts? (e.g. arbitrarily sending coins to everyone who has committed a trade on some exchange in the last X days.) Would enough information be known to allow an actor to enumerate arbitrary public addresses thus use this to attempt to hide in the crowd?

Ethically, that would be the less bad option, since the thief would be deprived off the income, even if it's not returned to the victim.
- ThrustVectoring 9y agoWhat if a portion of those sent coins are sent to attacker-owned wallets?
- jowsie 9y agoCrypto laundering seems pretty interesting.
- jnbiche 9y agoIf it's a non-negligible amount compared to other wallets, that would be pretty easy to track down. I mean, you'd look at new wallets compared to existing wallets.
- ThrustVectoring 9y agoThe attackers can still poison new wallets that appear on the chain - either you effectively shut down new wallet creation, or let the attackers possibly spend their coins.
- andreareina 9y agoLet's say I'm an innocent holder of the currency, and I receive x coins from a tainted account. I can post a transaction that sends x coins (or x - transaction_fee) to an unreachable address (say 0x0).
