Is there any DNM where you can use a CryptoNote based coin (e.g. Monero or Bytecoin)?
For the long story:
I liked it when DNMs were the place where the best solutions in anonymity were being applied (e.g. the first BTC thumblers/mixers). However nowadays I see that this community is severely lagging behind in terms of the anonymity tools it uses, which may severely affect us all in the future. I see vendors still using centralized thumblers/mixers for BTC when even distributed versions of thumblers, aka Coinjoin (implemented in SharedCoin and DarkSend) are being proven as flawed: http://www.coindesk.com/blockchains-sharedcoin-users-can-identified-says-security-expert/
Along the last couple of years I have been following the various anonymity proposals in detail: CoinJoin, Zerocoin, merge avoidance, stealth addresses, CryptoNote, etc. A Zerocoin system with no trusted 3rd parties, like the one being implemented on Anoncoin, is the proposal giving the strongest anonymity so far. However it is not implemented yet and will rely on Zero Knowledge Proofs which is a branch of cryptography lacking real world stress tests. Therefore, so far CryptoNote coins are the best option. CryptoNote relies on proven and tested cryptographic constructions and is able to: a) Hide who is spending coins, by sort of mixing your real input with as many fake inputs as you wish and making them indistinguishable between each other. It does this locally on your wallet without the need of servers or any peers sending the same exact amount as you, thus avoiding the CoinJoin drawbacks. b) Hide who is receiving coins and how many they are receiving by using a sort of "one time payment address" generated from your wallet's address. Unlike the stealth address implemented on top of Bitcoin, which generate a different address for every sender (if A sends twice to B the same "stealth address" will appear twice in the blockchain), on CryptoNote you get a different address for each transaction (if A sends twice to B, there will be two completely unrelated addresses on the blockchain). I sincerely advise those who are tech savvy to read their paper: https://cryptonote.org/whitepaper.pdf
Taking this into consideration I believe that still using Bitcoin on a Darknet Market is risking the security of us all unnecessarily. There are already better solutions out there.
Anything that involves switching to a different cryptocurrency will probably never happen unless there are raids proven to be caused by blockchain tracing. So much more bitcoin infrastructure (buying, selling, FAQs, etc) exists compared to any other cryptocurrency that there would need to be an extremely motivating force to get people to switch.
