I think it was mentioned, in the discussion between evan/anonymint that by darksending it multiple times through a number of nodes it reduces the bad-actor probabilities to a statistically safe degree to solve the issue that the darksend node knows who sends what.
I think I have a better solution than that, I want to turn the masternodes into I2P relays for darkcoin. So your client will pick one when you start, then relay any messages through that one. It encrypts all of the traffic, removes the connection between IP and address and it the blockchain is still a complete fog. Plus it'll be a private I2P, so it'll be super fast. Masternodes are going to be awesome

I2P is good, but if it's a replacement for chained pooling, that implies that it solves the problem of sybil masternodes (since that was the reason why chained pooling was needed). Is that the case, and if so, how does it solve the problem?
