> individual addresses and/or transactions can be seen as "tainted", and those coins can be tracked through the Blockchain. I'd say it's rather tainting transactions that use outputs of your "tainted" transaction. Personally I don't like bringing "coins" into discussion because people think it's something more material than it really is while in fact "coins" are just numbers in transaction outputs. If you have transaction that sends 2 BTC to an address you can't taint 1 BTC out of it because in this scenario they are just numbers, like you can't distinguish both 1s in 1 + 1 = 2. That you can track transactions back to their mining block is another matter.
