RISC Zero has launched the OP Kailua effectiveness mode, supporting the gradual transition of the OP chain to ZK Rollup

Zero-knowledge proof software developer RISC Zero has announced the launch of OP Kailua Validity Mode, enabling OP Rollup to upgrade to ZK Rollup without major technical changes, achieving higher security and faster settlement times. This mode eliminates fraud disputes, ensures transactions are finally confirmed within 1 hour, provides stronger security than traditional fraud proofs, and is adapted for phase two decentralized deployment.
In addition, Validity Mode is cost-effective and suitable for high-throughput OP chains. At the same time, Kailua also offers Hybrid Mode which allows OP Rollup to introduce ZK Fraud Proofs first with lower margin requirements and faster dispute resolution capabilities to enhance security. Currently multiple rollup projects such as BOB and Eclipse have begun integrating OP Kailua gradually transitioning towards ZK.
