The blockchain landscape continues to evolve at a rapid pace, and OKX is positioning itself at the forefront of innovation with its strategic vision for the future of its native blockchain infrastructure. Star Xu, founder of the globally recognized OKX exchange, recently shared pivotal updates about OKBChain, revealing a bold roadmap that underscores the platform’s commitment to scalability, performance, and developer empowerment.
According to Xu’s announcement on social media, OKBChain will emerge as a Layer 2 (L2) Ethereum sidechain, initially built on sidechain technology before transitioning into advanced zero-knowledge (ZK) rollup solutions. This evolution reflects a long-term strategy aimed at maximizing transaction efficiency while maintaining Ethereum’s robust security model.
Meanwhile, the existing OKT Chain will remain operational as a standalone Layer 1 (L1) blockchain, ensuring continuity for current decentralized applications (DApps) and users. This dual-chain architecture allows OKX to cater to diverse development needs—offering high-performance capabilities on L1 while leveraging Ethereum’s ecosystem strength through L2 scaling.
"OKT Chain will continue be a L1 Chain, the closest launch will be OKTC WASM which allow us develop high performance Dapp through rust or c++. OKB Chain will be a L2 Chain of Ethereum, starting from side chain technology and will develop to ZK technology."

This clear distinction between OKT Chain and OKBChain highlights OKX’s modular approach to blockchain development—one that balances innovation with stability.
Dual-Chain Strategy: Powering Next-Gen DApp Development
OKX’s core blockchain strategy now revolves around two complementary chains:
- OKT Chain (L1): Continues as an independent Layer 1 network optimized for speed and flexibility.
- OKBChain (L2): Evolves into an Ethereum Layer 2 solution focused on scalability, security, and interoperability.
OKT Chain: High-Performance Development with WASM Support
A key milestone in the OKT Chain roadmap is the introduction of WASM (WebAssembly) virtual machine support. This upgrade will empower developers to build high-performance DApps using systems programming languages like Rust and C++, known for their efficiency and low-level control.
WASM enables near-native execution speeds, making it ideal for resource-intensive applications such as blockchain games, DeFi protocols requiring complex computations, and real-time financial services. By supporting these languages, OKX lowers the barrier for traditional software engineers to enter the Web3 space.

OKBChain: Scaling Ethereum Through ZK Technology
While OKT Chain focuses on autonomy and performance, OKBChain is designed to solve one of Ethereum’s most pressing challenges: scalability. As a Layer 2 sidechain, it will initially leverage sidechain mechanisms to offload transactions from Ethereum’s mainnet, reducing congestion and lowering gas fees.
However, the ultimate goal is integration with ZK-rollup technology, which bundles thousands of transactions off-chain and submits cryptographic proofs to Ethereum for verification. This approach ensures:
- Enhanced security via Ethereum’s consensus layer
- Massive throughput improvements
- Lower transaction costs
- True composability with other Ethereum-based protocols
This phased transition—from sidechain to ZK-powered rollup—demonstrates OKX’s forward-thinking approach, aligning with industry trends toward secure, efficient, and trustless scaling solutions.
Core Blockchain Products Driving Innovation
Both OKT Chain and OKBChain are central components of OKX’s broader blockchain strategy. They are not just technical upgrades but foundational platforms aimed at fostering a vibrant ecosystem of developers, projects, and users.
OKX has emphasized that both chains fall under its "core chain strategy", indicating a unified vision despite their differing roles. This dual-track model allows the exchange to:
- Maintain backward compatibility and support for existing DApps on OKT Chain
- Innovate aggressively on OKBChain by tapping into Ethereum’s vast developer community and liquidity
- Offer developers choice: build for maximum performance (OKT) or maximum interoperability (OKB)
Such flexibility strengthens OKX’s position as a comprehensive Web3 infrastructure provider—not just a crypto exchange.
FAQ: Understanding OKX’s Blockchain Vision
What is the difference between OKT Chain and OKBChain?
OKT Chain operates as a Layer 1 blockchain, providing independent consensus and high-speed transaction processing. OKBChain, in contrast, is a Layer 2 solution built on top of Ethereum, designed to scale Ethereum-based applications using sidechain and future ZK-rollup technologies.
Will OKT Chain be discontinued?
No. OKT Chain will continue to function as an L1 chain. It will receive upgrades like WASM support to enhance its capabilities for high-performance DApp development.
Why is OKX building a Layer 2 on Ethereum?
Ethereum remains the largest ecosystem for decentralized applications. By building OKBChain as an L2, OKX enables developers to access Ethereum’s security and user base while benefiting from lower fees and higher throughput.

What are ZK-rollups, and why do they matter?
Zero-knowledge rollups (ZK-rollups) are scaling solutions that process transactions off-chain and submit validity proofs to Ethereum. They offer faster speeds, lower costs, and strong security guarantees—making them a leading path toward mass blockchain adoption.
Can developers build on both chains simultaneously?
Yes. Developers can deploy applications on OKT Chain for standalone performance or use OKBChain to integrate deeply with Ethereum’s ecosystem. This dual-option model promotes innovation across different use cases.
When will the OKBChain testnet launch?
The testnet for OKBChain is scheduled to launch as planned in March, according to official announcements. This marks a critical step toward public deployment and developer onboarding.
Strategic Implications for the Web3 Ecosystem
OKX’s decision to adopt a dual-chain architecture reflects a maturing understanding of blockchain trade-offs. Rather than forcing all activity onto a single chain, the company embraces specialization—each chain serving distinct but complementary purposes.
This approach mirrors broader industry movements seen in platforms like Polygon (with Polygon PoS and zkEVM) and BNB Chain (with BSC and opBNB). By offering both an independent L1 and an Ethereum-aligned L2, OKX ensures resilience, choice, and scalability for its ecosystem participants.
Moreover, the focus on ZK technology places OKX at the cutting edge of cryptographic innovation. As ZK proofs become more efficient and widely adopted, early movers like OKBChain stand to gain significant traction among privacy-conscious and performance-driven projects.

Final Thoughts: A Forward-Looking Blockchain Roadmap
Star Xu’s vision for OKBChain signals more than just a technical upgrade—it represents a strategic pivot toward sustainable growth in the Web3 era. With a clear separation between OKT Chain (L1) and OKBChain (L2), OKX delivers flexibility without fragmentation.
Developers now have powerful tools at their disposal: WASM support for high-performance computing on OKT Chain, and a clear path to Ethereum scaling via ZK-rollups on OKBChain. For users, this means faster transactions, lower costs, and access to richer decentralized experiences.
As the testnet launch approaches and further technical details emerge, the crypto community will be watching closely to see how this dual-chain model performs in practice—and whether it sets a new standard for exchange-led blockchain innovation.
