EY launches blockchain privacy sandbox to promote the implementation of enterprise-level ZK applications.

Big Four accounting firm Ernst & Young (EY) announced the launch of the Blockchain Privacy Sandbox, enabling developers to build and test privacy-preserving smart contracts on EVM public chains such as Ethereum. Based on its open-source zero-knowledge proof compiler Starlight, the tool allows for the implementation of privacy features without altering Solidity contract logic and lowers the deployment barrier through a web environment. EY stated that the platform aims to help enterprises validate privacy use cases before formal integration. Data shows that the zero-knowledge proof market is projected to reach approximately $7.6 billion by 2033.
