With a divide and conquer approach, we might be able to get zerocoin functionality for NXT before zerocoin!
I'm not sure it's not a theft...
Not a theft, they want us to port, they describe exactly how to do it.
They wanted bitcoin to adopt their libzerocoin
They wanted altcoins to adopt their solution
Nobody did, so they were forced to start developing their own coin
They are professors, not really into making new coins

We will be updating this site soon to include details of our new version described by Matt Green at Real World Crypto 2014
What is Zerocoin?
Zerocoin is a proposed extension to the Bitcoin payment network that adds anonymity to Bitcoin payments. Just as paper currency once gained its value from being redeemable for gold, zerocoins gain their value from being redeemable for bitcoins. We believe that tools such as Zerocoin are necessary as the current Bitcoin payment network does not offer strong privacy protections. The main idea behind Zerocoin is to place anonymity technology into the Bitcoin network itself. This is substantially different from previous anonymization technologies such as “laundries”, since Zerocoin does not rely on a trusted centralized party that can fail or become corrupted.
What makes Zerocoin different from previous approaches:
Zerocoin operates in the Bitcoin network and is implemented as a series of extensions to the existing Bitcoin protocol. This approach means that Zerocoin can be deployed without relying on a central coin issuer or bank (as used in previous e-cash schemes). Moreover, since no single trusted party operates the Zerocoin system, attacks on Zerocoin must take on a substantial fraction of the Bitcoin network.
Zerocoin uses provably secure cryptographic techniques to ensure that Bitcoins cannot be traced. These techniques allow users to conduct transactions on the Bitcoin network while receiving strong mathematical guarantees that the transactions cannot be traced. These guarantees remain in place even if a portion of the Bitcoin network is compromised by an attacker.
Other anonymous cash systems rely on distributing the work of anonymizing users amongst a set of parties. This approach works well if all parties are fully available but can be subject to “denial of service” attacks where a small number of nodes are taken offline. Because Zerocoin is built on top of Bitcoin, it is widely distributed among all the Bitcoin peers, ensuring that the system can remain available even when many nodes are compromised.
