Important ANN:

We received news from the Zerocoin Team itself that they have abandoned the zerocoin project. Zerocoin is now a dead project. We had started implementing their library to Libertycoin hoping to implement a fully functional and stable version when they released more updates. Unfortunately, there is nothing we can do now. We will start removing the zerocoin library that we added to the code, and we will consult with our developer if there are other anonymizers we can deploy in the future. For the time being we will realease an update removing zerocoin from our code, and Libertycoin will remain as a great X11 100% proof of stake coin with 16.5 Million units.

About implementing the Zerocash
We will certainly study it, and if we consider it stable we will do it. They have already abandoned one project, so we don't want to take the risk of implementing something unstable that could be abandoned in the future. We paid a high price with zerocoin.
