So the 200k are used to mix coins being sent across the network?
Can you explain the mechanism a little bit more?
I think they use typical coinjoin techniques. There are many details in the forum, such as in darkcoin thread:

https://bitcointalk.org/index.php?topic=618552.msg7282648#msg7282648several other coins have it, with some variations, but the ideas are to mix the coin you send to a pool (or many pools), and forward coins to destination using a different pool so the source-destination can not be traced. This way to achieve the anonymous send.
Now that is an explanation.
