So I notice our friend Chaeplin, is doing a lot of talking in the other XC topic and his criticisms fall into two categories below which I respond to here:
1. Xnodes could in theory "steal" XC.
Answer: My understanding is that Rev 2 will have a trust learning algorithm and the dev has said coins cannot be stolen.
He said IIRC "mixers don't steal coins" . People do
No problem if all parts of the tx's go on the same block.
However if we look at DRK, I believe they use signatures which removes the incentive for mixer nodes to steal the mixed coins. Why don't we also do that ON TOP of the trust learning algorithm? Then we have the best of both and that completely destroys the argument.
Can you ealborate. I'd love to get this clear. In the unmod thread it is being claimed IIUC that DRK just witnesses and verifies the transaction, which is different to there just being an incentive not to steal, while having the ability to. I'm just asking here and trying to learn and I'm not very tech savvy.
2. XC transfer is not anonymous and can be linked
Answer: Dev has an open challenge right now that hasn't been solved yet, based on the new multi-path protocol. I'm confident in the devs ability. I would also be interested to see whether Chaeplins methods can be applied to DRK?
In its present form, the XC mixer, like coinjoin leaves some trail, and if there are only a few transactions to choose from the possibility of
guessing is greatly improved. At least that's how I understand it.
Chaeplins method or one similar could be applied to DRK IIUC, because even though the coins get mixed there is still
some information, some clues, but again IIUC it's not the "hard link" that Dan the dev asked for. I think Kristov Atlas has something that can be applied to DRK to do just that
I'd love to hear the thoughts of other to see if i've misunderstood.
Peace to all

this is the reason XC is treated with such animosity from Darkcoin. Post's like these.
