According to ChainCatcher, zero-knowledge proof software developer RISC Zero has announced the launch of the OP Kailua Validity Mode, enabling OP Rollup to upgrade to zk rollup without major technical modifications, achieving higher security and faster settlement times. This mode eliminates fraud disputes, ensures transaction finality within 1 hour, and has been adapted for the second stage of decentralized deployment.

Moreover, the Validity Mode is cost-effective and suitable for high-throughput OP chains. Test data shows that transaction costs on the Base chain can be as low as $0.00012 per transaction. Meanwhile, Kailua also provides a Hybrid Mode, allowing OP Rollup to introduce ZK fraud proofs, enhancing security with lower margin requirements and faster dispute resolution.

Currently, multiple Rollup projects such as BOB and Eclipse have begun integrating OP Kailua, gradually transitioning to ZK, with a solution that does not require changing technical architecture or sacrificing cost-effectiveness. Interested parties can now contact RISC Zero by filling out an application form, and the team will assist with deployment.
