Build on Bitcoin (BOB) has launched a pivotal upgrade integrating zero-knowledge (ZK) fraud proofs, advancing its position in L2Beat’s decentralization rankings and enhancing Bitcoin’s DeFi potential.
-
This technical enhancement replaces traditional fraud-checking with cryptographic proofs, significantly accelerating dispute resolution and lowering participation barriers for users and validators.

According to BOB co-founder Alexei Zamyatin, the Kailua upgrade marks a crucial milestone by achieving Stage 0 on L2Beat, setting the stage for full Ethereum-level security on Bitcoin.
Build on Bitcoin’s Kailua upgrade integrates ZK fraud proofs, propelling its decentralization on L2Beat and unlocking Ethereum-style DeFi capabilities on Bitcoin’s network.
BOB’s Kailua Upgrade Advances Decentralization and Security on L2Beat
The recent Kailua upgrade by Build on Bitcoin (BOB) represents a significant leap forward in the layer-2 ecosystem, positioning the network at Stage 0 on L2Beat’s decentralization scale. This platform evaluates layer-2 protocols based on stringent criteria, including the presence of functional fraud-proof mechanisms and governance structures like security councils.
BOB’s adoption of zero-knowledge fraud proofs within an optimistic rollup framework replaces the conventional, slower fraud verification process. This innovation enables transaction disputes to be resolved cryptographically within minutes, enhancing both network security and user experience. As Alexei Zamyatin highlighted, this upgrade addresses the core challenge of implementing a robust proof system, effectively aligning BOB’s security model with Ethereum’s standards.
While the upgrade marks a foundational achievement, BOB’s roadmap includes establishing a security council composed of diverse external entities and implementing delay mechanisms for code updates—both essential for progressing to higher decentralization stages on L2Beat.
Strategic Implications for Layer-2 Maturity and User Adoption
BOB’s progress on L2Beat not only signals technical maturity but also reflects growing confidence in Bitcoin’s capacity to support complex DeFi applications traditionally dominated by Ethereum. The platform’s ability to secure value and maintain decentralization is critical for attracting institutional and retail users alike.
With only a handful of protocols reaching Stage 2 on L2Beat, BOB’s trajectory suggests it could soon join this elite group, enhancing its appeal as a secure and scalable solution. This momentum may catalyze broader adoption of Bitcoin-based DeFi, leveraging BOB’s unique architecture to bridge the gap between Bitcoin’s security and Ethereum’s programmability.
Unlocking Zero-Knowledge Verification and Bitcoin-Backed DeFi
The integration of zero-knowledge fraud proofs on BOB paves the way for zk verification directly on Bitcoin, a development with profound implications for blockchain interoperability and security. Zamyatin emphasized that this upgrade, combined with BitVM technology, enables validity proofs generated on BOB to be verified on Bitcoin’s mainnet, reinforcing the security guarantees of cross-chain operations.
This synergy between BOB and BitVM forms a foundational layer for a Bitcoin-secured bridge, facilitating smart contract execution and decentralized finance functionalities natively anchored to Bitcoin’s robust network. By enabling native BTC assets on BOB, the platform offers a compelling gateway for users and protocols seeking to leverage Bitcoin’s liquidity within a DeFi context.
Future Outlook: Bitcoin DeFi’s Potential to Surpass Competitors
Looking ahead, BOB’s advancements could accelerate Bitcoin’s emergence as a dominant DeFi platform, potentially surpassing Ethereum and Solana in user base and transaction volume. Zamyatin’s projection of over 300 million Bitcoin DeFi users underscores the transformative potential of integrating zero-knowledge proofs and rollup technologies on Bitcoin.
This growth trajectory aligns with broader industry trends favoring scalability, security, and decentralization, positioning BOB as a critical infrastructure player in the evolving blockchain landscape.
Conclusion
Build on Bitcoin’s Kailua upgrade marks a decisive step toward achieving full decentralization and Ethereum-level security on Bitcoin’s layer-2 network. By implementing zero-knowledge fraud proofs and advancing through L2Beat’s stages, BOB is setting new standards for Bitcoin-based DeFi. As the platform continues to develop governance frameworks and security mechanisms, it stands poised to unlock unprecedented opportunities for users and institutions seeking secure, scalable, and interoperable decentralized finance solutions anchored in Bitcoin’s unparalleled security.
