Zerocoin is a cryptographic extension to Bitcoin. During its development, the developers decided to make use of group signature schemes to store and verify the coins. In order to compare the performance of Simple Authentication Scheme and the Dynamic Signature Scheme and figure out which one is the optimal choice for the Zerocoin scheme, I implemented them in Java and analyzed them theoretically. This paper will discuss the performance difference between two schemes, the Java implementation of them and the analysis.
