Anonymize the Blockchain Using CoinJoin or Mixcoin

We need to enhance the cryptocurrency Neutrino to anonymize the blockchain. See the source for Neutrino at [url removed, login to view]

The main problem we are trying to solve is this: If a user is somehow linked to one transaction in the blockchain, then other information about that user’s transactions can be deduced, including, in some scenarios, the user’s complete transaction history. This is actually a problem in almost all crypto-currencies. We're looking for someone who is already very familiar with the Bitcoin/Litecoin source code.

We know of three proposed solutions to this issue right now: Zerocash (formerly Zerocoin), CoinJoin and Mixcoin. We’re not stuck on those solutions, though, if you know of another workable solution.

We are looking for a solution that is similar in spirit to Darkcoin's implementation of CoinJoin in that:

* the transaction anonymization feature should integrated into the command-line and GUI clients

* transaction anonymization should be on by default for the casual user

* no configuration should be required by the casual user

* only minimal configuration is required by a client that is hosting the joining of transactions--these are called "master nodes" in DarkCoin.

Also, for what it’s worth, one cryptocurrency, Darkcoin has claimed to have implemented a particular approach to CoinJoin. As of May 25, Darkcoin had not yet released the full client source code for doing spend transactions, but they say they will release the full source in early June. Here are some links:
