Every wallet that receives funds from the flagged wallet is tainted until they send it back to that wallet. All of the funds, not just the tainted amount.

This doesn't work in practice. Transactions using Bitcoin "addresses" are just one (out of many) transaction types. As far as I understand the protocol it's possible that you receive those coins via a transaction type that doesn't have an associated Bitcoin sender address.

  "Every wallet that receives funds from a tainted wallet becomes tainted" doesn't (in any way I see) conflict with the notion that there are transactions without a sender.

    I meant the "until you send it back part". If "every wallet becomes tainted" and "you can't send it back" this would make it trivial for an attacker to taint a large number of wallets in the Bitcoin network.

      If there is no sender, how does the receiver become tainted?

"[...] until they send it back to that wallet." Or forfeit it to the feds, at which point they can mark them untainted before they auction them off.

  Doesn't tainting then become "assigning to the USA government"? Why should that be the case?
  - dllthomas 13y ago
    It doesn't have to be, in principle. It depends what organization is doing the tainting. In practice, it is comparatively likely to be the case because tainting of this sort is likely to relate to the criminal justice system, and I don't expect the relevant portions to be privatized anytime soon. If you mean the US rather than other governments, mostly because we seem comparatively eager to enforce our laws abroad, though I expect other governments would get in on the game.

So then anyone with tainted coins can completely lock down arbitrary wallets?
