fhEVM v0.4: New Encrypted Types and Asynchronous Decryption
Blog post from Zama
The latest version of fhEVM, v0.4, introduces new encrypted data types and an asynchronous decryption API to enhance performance and efficiency. This update supports encrypted booleans, 4-bit and 64-bit integers, and addresses, enabling more cost-effective operations and expanding use cases for privacy-preserving decentralized applications. The asynchronous decryption API allows smart contracts to request decryption via an oracle and receive results through callbacks, freeing resources and optimizing scalability compared to previous synchronous methods. This feature replaces synchronous decryption, which will be deprecated in the next version. Additionally, a new standard library of contracts, including ERC20 and DAO, has been released to streamline development and foster innovation. Developers are encouraged to upgrade their code to utilize these new features, with resources available for support and further information.
