In the last 2023 blocks, only 26 were orphaned. That's about 1,3% odds of loosing all the meltmined coins (to a lucky miner). I prefer a 1% chance of loosing the melted coins than your tainted coin system. Tainted coins will affect all the bitcoin economy badly but meltmining pools only have a 1% chance to loose the block. I insist, tainting coins is a very bad idea because it will hurt all the bitcoin economy and the solution is not so risky for a melting transaction.
Bro, again, this has absolutely NOTHING to do with tainting. You have no idea what you're talking about.
He absolutely have no idea what he's talking about. He thinks coins are magically laundered by using as transaction fee. Transaction fee is nothing more than
a reduced value of the output. If someone tries to melt some dirty coins by sending unreasonably high fee, the block reward will simply become dirty. Not to mention that setting up a coin melting pool cannot stop people using colored coins, unless he is able to spend coins that are not belonging to him.
However, I still hope he will set up a pool like that, so I may be able to grab some of those easy coins.
There are some tricks you can play though if you have the mining power to create a block in a reasonable time. Then you can deliberately include transactions which increase the noise level and make it hard for any tracing software to infer the origin of coins. If done right, the tracing of the coins you want to launder becomes unpractical.
