StarkWare has open sourced the zero-knowledge proof code ethSTARK

Zero-knowledge proof research and development agency StarkWare has open sourced ethSTARK on GitHub. StarkWare stated, “In 2018, we received funding from the Ethereum Foundation to explore STARK-friendly hash functions and open source ZKP codes. The proof speed of ethSTARK codes will be 20 times faster than any existing ZKP codes.” In July 2018, StarkWare received a US$4 million grant from the Ethereum Foundation to develop STARK-friendly hash functions and technologies and provide open source code for the ecosystem. STARK will allow the blockchain to expand on a large scale (such as sharding) with both privacy and post-quantum security.
