Kailua: RISC Zero's hybrid ZK fault proofs for the OP Stack
Quote253 words
Explains Kailua, a RISC Zero hybrid for OP chains that replaces interactive fault proofs with non-interactive ZK fault proofs, generating proofs only during disputes. Argues this cuts proving cost versus OP Succinct while giving sub-1-hour finality.
Key claims
Settlement in under 1 hour vs up to 7 days for interactive fault proofs
ZK proving only during disputes saves integrators millions annually vs OP Succinct

Kailua by @RiscZero is a hybrid architecture for OP chains which improves security, reduces operational costs & minimizes finality delays.
Built on the foundation of Zeth, the first Type-1 zkEVM, Kailua uses the R0 zkVM to introduce a non-interactive ZK fault-proof system that combines the unique benefits of optimistic and ZK rollups in one.
Unlike traditional optimistic rollups that rely on slow, interactive fault-proof systems (with finality delays of up to 7 days), Kailua resolves disputes using ZK proofs powered by @boundlesshq, significantly speeding up time to finality.
Compared to other ZK solutions for the OP stack such as "OP Succinct", Kailua saves integrators millions of dollars in annual proving cost, requiring proofs to be generated only during disputes.
The Kailua system also stands out with regards to its customizability, allowing integrators to start with occasional validity proofs, increase frequency over time, and transition to fully validity proving all blocks when ready.
In summary, Kailua provides:
โ Fast finality: Settlement in < 1 hour
โ Low cost: Only ZK proving during disputes
โ Easy integration: Full OP Stack compatibility
โ ZK endgame: Clear path to full validity proving
This is a game-changer anon.
