Tante, surely you want a solution that cannot be broken? Darkcoin's market cap is only $10 million. Impressive by our standards, but simply pittances to any worthy adversary.
Darkcoin should be aiming for an unbreakable solution, an unhackable solution, anonymity that cannot be overcome simply by owning a large enough % of coins.
We don't want users to simply feel safe, but to actually be safe. Coinjoin, darksend, and any other future derivative that relies on mixing pools of transactions is inevevitably going to fail the anonymity test, as the signer of the pooled transaction has access to information.
The only true solution is an encrypted packet of information approach, where although the packet is visible on the network, the contents - and ability to open said contents - is only accessible to the recipient (ie, their encrypted wallet's private key).
Nope, i'm not here to troll. In fact, my guess is that the price and market share will continue to rise. So if you are only loyal to this coin to see an increase in your wealth you probably will. But no one with serious $ they wish to transfer with reliable anonymity will use your coin.
sorry, I still don't see a hole. Unless an entity has control of all the masternodes in a transaction, they will never know what happened. Better still, non of these transactions ever go on the blockchain, so the past can never be revealed. Finally, Evan is constantly coming up with other ideas to improve upon what we have. Nope, you can't convince me that what Evan has come up with is faulty. i won't say that there aren't other great solutions to be found and implemented though. I'm sure there will be. Monero sounds interesting, i'm looking at it, but if I can't understand it ultimately, I won't feel comfortable using it. But that's just me

BTW, if an entity should get lucky and discover the ip address and payment info for a transaction, their luck would probably reveal a transaction where one entity bought some new furniture, another sent his nephew some graduation coin, and a third paid for his vacation in Bali. None of which are illegal, so they spent all this money to try and spy on normal people doing normal things (i maintain that most people don't do illegal things). The likelihood some NSA top official would risk his plushy career on spending a fortune on cryptos is pritty slim. They didn't get their ass widening seated plushy jobs from taking risks, believe me.
