One of the most enjoyable things we do at ECC is working on cutting-edge cryptography. In our continued effort to ensure that Zcash benefits as much as possible from groundbreaking crypto innovations, part of what we do is to design our own cryptographic constructs to improve performance and security. For the Halo 2 project, we have designed a new cycle of elliptic curves, Pallas and Vesta, which we collectively refer to as the Pasta curves.
