At last people who get it...What do you think AnonyMint about Anoncoin? And what is your opinion about Megacoin integrating 0coin??
Integrating I2P into the Anoncoin mining (I assume it is) forces all miners on a level-playing field w.r.t. to the extra latency caused by mix-net routing. However, you may only need the high-latency routing (to prevent timing attacks for maximum anonymity confidence) when you are announcing a solution to PoW for a block or sending a transaction. I2P
won't offer support for high-latency routing until version 3.0.
Zerocoin is not a panacea because the government can force you to reveal which coins you took out the other side, if they know your identity on either side of the Zerocoin mixer. People think that just because the coinmixer in Zerocoin can't be pressured (no one controls it), that the government is impotent. No way. They can arrest you for failing to provide your password on your laptop, surely they can throw you in contempt of court for 7 years (as they did to Martin Armstrong) if they know you own a coin on either side of mixer and you refuse to provide them the keys on the other side. Saying you "forgot" runs you afoul of the tax requirement to keep records for 5 years, and now the courts have been finding that any such lapses are "willful intent" which means criminal charges and jail.
So the high-latency mix-net (e.g. I2P version 3.0 hopefully) is a critical requirement to obtain anonymity.
And so you think they don't know your identity because you used (when it becomes available) high-latency I2P version 3.0, but then the problem is the merchant you spent to brought into the tax office and forced to reveal your identity. Any weak link in the chain of anonymity dominos back to you, when the threat is a Gestapo. When Berlin wall fell, it was discovered dossiers neighbors were spying on each other, listening devices all over, etc..
Zerocoin does bring the benefit that makes block chain path analysis more unlikely. So assuming the government can't interrogate everyone, it raises the confidence that a path back to you is scrambled. But it isn't enough by itself. And it has a large cost on the blockchain, and I need to actually study that more to see if it going to scale.
In my mind, the high-latency I2P is more critically needed pronto. Tor is limited to 3 hops which is inadequate. Mix-nets provide anonymity if just one peer in the chain isn't owned by the attack. Three hops is not enough to give me confidence. Note also need high-latency to prevent timing analysis, and Tor has no plans to offer high-latency.
I2P supports low-latency too and the traffic is mixed, so that means the network can be popular because most people want low-latency and low anonymity.
You don't use high-latency networks for anything that needs to be interactive, e.g. web browsing and chat. So those will never be very anonymous, unless you accept them being very slow and non-interactive. But for sending a transaction or PoW solution, a few seconds delay in order to get very high confidence of anonymity is a correct tradeoff. Note high-latency allows to mix up the transactions that come into a peer before they are routed back out, and this messes up timing-based statistical analysis that has been shown to break anonymity in mix-nets like Tor (and perhaps I2P).
Anoncoin may have gotten one part of the design correct, but there are other crucial things we need to fix in Bitcoin and the design needs to be holistic, because some things impact each other.
