The blockchain landscape is rapidly evolving, and OKX has positioned itself at the forefront with the official release of the OKB Chain (OKBC) development roadmap. This strategic initiative outlines a clear, three-phase evolution of OKBC into a high-performance, Ethereum-aligned Layer 2 ecosystem. Designed to enhance scalability, interoperability, and user experience, the roadmap reflects OKX’s long-term commitment to building a robust infrastructure for decentralized applications and next-generation digital asset interactions.
At its core, OKBC is envisioned as an Ethereum Layer 2 network that will progressively advance from a proof-of-authority (PoA) sidechain to a fully-fledged ZK Rollup platform—ultimately enabling seamless cross-chain communication and Web2-like usability in decentralized finance (DeFi) and beyond.
Phase 1: OKB Chain V1 – High-Performance EVM & Wasm-Compatible Sidechain
The foundation of the OKBC network begins with OKB Chain V1, an Ethereum-compatible PoA sidechain optimized for speed and low-cost transactions. This initial phase prioritizes developer accessibility and user adoption by supporting both EVM (Ethereum Virtual Machine) and Wasm (WebAssembly) environments.
By embracing dual compatibility, OKBC V1 opens the door for projects from multiple ecosystems—such as Ethereum, Polkadot, and Cosmos—to migrate or deploy seamlessly. Developers benefit from familiar tooling and reduced gas fees, while users enjoy faster transaction finality without sacrificing security.
"OKBC V1 lowers the barrier to entry for builders and traders alike, serving as a launchpad for innovation within the OKX ecosystem."
The testnet for OKB Chain V1 was launched in Q1 2023, marking a critical milestone in network validation and community engagement. This phase establishes OKBC as a reliable scaling solution while laying the technical groundwork for future upgrades.

Phase 2: OKB Chain V2 – Native ZK Rollup with zkEVM and zkWasm
Building on the success of V1, OKB Chain V2 represents a major technological leap: a native ZK Rollup platform built directly on Ethereum. This upgrade leverages zero-knowledge proof technology to deliver unprecedented levels of scalability and security while maintaining full alignment with Ethereum's consensus layer.
Key features of OKBC V2 include:
- zkEVM Development: A zero-knowledge implementation of the Ethereum Virtual Machine, enabling existing Ethereum dApps to transition smoothly with minimal code changes.
- zkWasm Support: Extending ZK capabilities to WebAssembly-based smart contracts, broadening the range of supported programming languages and use cases.
- Enhanced Throughput: By batching thousands of transactions off-chain and submitting compact proofs on-chain, OKBC V2 drastically reduces congestion and gas costs.
This phase ensures that OKBC remains at the cutting edge of Layer 2 innovation, offering high throughput, low latency, and trustless security—all essential for mass adoption.
Phase 3: OKB Chain V3 – Interoperable ZK Ecosystem & Application-Specific Solutions
The final stage of the roadmap, OKB Chain V3, aims to solve one of blockchain’s most persistent challenges: fragmentation across ZK Rollups. OKBC V3 will introduce advanced cross-rollup communication protocols, allowing different ZK-powered chains to interact seamlessly.
Beyond connectivity, this phase focuses on delivering application-specific rollups—customized Layer 2 environments tailored for particular use cases such as decentralized exchanges (DEXs), gaming, or identity systems. These specialized solutions will operate under the unified OKBC framework, using OKB as the native utility token to facilitate governance, staking, and cross-chain operations.
A key ambition of OKBC V3 is to bridge the gap between centralized (CEX) and decentralized (DEX) experiences. By integrating high-speed execution, intuitive interfaces, and aggregated liquidity—all powered by ZK technology—OKX envisions DEX platforms that offer near-instant trades, deep liquidity, and minimal slippage, rivaling traditional centralized exchanges in performance while preserving decentralization.

Frequently Asked Questions (FAQ)
Q: What is OKB Chain (OKBC)?
A: OKB Chain (OKBC) is a Layer 2 blockchain network developed by OKX, designed to scale Ethereum through a phased approach—from a PoA sidechain to a ZK Rollup-based ecosystem with full cross-chain functionality.
Q: How does OKBC differ from other Layer 2 solutions?
A: Unlike many L2s focused solely on EVM compatibility, OKBC uniquely supports both EVM and Wasm environments. Its long-term vision includes native zkEVM/zkWasm development and application-specific rollups, setting it apart in terms of flexibility and future-readiness.
Q: Is OKBC replacing OKT Chain (OKTC)?
A: No. While OKBC focuses on Ethereum scaling as a Layer 2 solution, OKX continues to support and develop OKT Chain (OKTC) as an independent Layer 1 public blockchain. Both networks will coexist and serve complementary roles.
Q: What role does the OKB token play in OKBC?
A: OKB serves as the native utility token of the OKBC network, used for transaction fees, staking, governance, and incentivizing ecosystem participation across its various phases.
Q: When will OKBC V3 be launched?
A: While specific timelines for V3 have not been announced, V1 launched its testnet in Q1 2023, with ongoing development for V2 currently underway. Updates are expected as milestones are achieved.
Q: Can developers build on OKBC today?
A: Yes. With EVM and Wasm support in V1, developers can already deploy smart contracts and dApps on the OKBC testnet. Tools, documentation, and SDKs are available to support early-stage development.
