Odaily Planet Daily News Zero-Knowledge Proof software developer RISC Zero announced the launch of hybrid architecture tools and contracts Kailua, a software suite for upgrading Optimistic Rollup to Hybrid ZK Rollup, with its first implementation supported by Optimism's Kona Rollup state transition engine. Kailua's hybrid architecture can be used to support the normal operation of Rollups without worrying about ongoing proof costs and time, and can also reduce additional proof costs for users. Kailua is a fully open-source project, currently under rapid development, and is only suitable for testing environments and not for production environments.
