ECC is proud to introduce ZIP 224, which provides a path to bringing Halo 2 to Zcash. The Halo 2 zero-knowledge proving system, invented and developed at Electric Coin Co. (ECC), eliminates the trusted setup, reducing the attack surface of the Zcash protocol and improving assurance about ZEC supply integrity. As the first deployment of the Halo 2 zero-knowledge platform, this would enable future circuit upgrades without the need for setup ceremonies, making the Zcash shielded protocol more agile for future improvements, such as supporting additional assets. In addition, the ZIP paves the way for proof aggregation and blockchain succinctness, two scalability improvements that enable the Zcash protocol to stay abreast of adoption.
