DarkSend does not use blind signing, and, if I remember correctly, the reason is that the implementation had DOS issues and the attacker could get away with it. So given that the node knows what it signs, the next alternative was
Right, this is a centralized approach... a central server can deanonymize people. There may be many of these servers, but you're still trusting them to not be bad. It may be acceptable it's probably better than nothing at all. But things like this is precisely what Ozziecoin is slamming. Ironically, because the CJ thread post 5 describes how you can deal with the dos attacks while actually being private for everyone: If the transaction fails, everyone deanonymizes their attempt, and anyone who fails to deanonymize (or is directly shown to be the party refusing to sign) is banned. It's a PITA to actually implement, I agree.
If it was part of Bitcoin, it wouldn't require Dark Wallet, would it?
Having something in the protocol doesn't mean that there is an interface to it. I was doing CoinJoins back in 2011-2012, in public too
https://bitcointalk.org/index.php?topic=139581.0 ... no software was required for it once the raw transaction interface made it into a release. The point here being that none of this needs an altcoin, yes it may need all sorts of client software and such, but there is no need to invoke another currency
except to Make Money Fast.I think you're jumping to conclusions and judging everyone. In the case of Darkcoin, the devs barely made much money for 4 months. Then they provided a tech solution that the market needed because privacy was not being implemented in bitcoin; hence why the coin value jumped. To imply that this is a pump and dump - frankly, that stuff should be beneath you. I for one did not buy darkcoin to pump it up. I do however believe it is fundamentally more valuable than bitcoin and litecoin because it appears to my eyes to have a functioning privacy layer, which is sadly lacking in the other coins.
