TechFlow News — OKX has released the development roadmap for its public blockchain, OKB Chain (OKBC), positioning OKBC as an Ethereum Layer 2 network. Starting with sidechain technology, OKBC will gradually evolve into a ZK-based Layer 2 scaling solution, while continuing to develop its Layer 1 blockchain, OKT Chain (OKTC).
Currently, OKX has planned a three-phase strategy to build the OKBC network, detailed as follows:
- OKB Chain V1: An Ethereum PoA sidechain focused on delivering high performance and low transaction fees, compatible with both EVM and Wasm ecosystems, ensuring smooth experiences for users and developers. The OKBC V1 testnet is scheduled to launch in Q1 2023.
- OKB Chain V2: An Ethereum-native ZK Rollup platform that will offer a Turing-complete ZKVM. This upgrade will significantly enhance scalability and efficiency while maintaining compatibility with the Ethereum ecosystem. Development of zkEVM and zkWasm is currently underway.
- OKB Chain V3: Enabling cross-chain communication between ZK Rollups and proposing specialized application solutions based on the V2 platform. Achieving this goal will deliver a Web2-like user experience. By using OKB as the bridge on Layer 2, DEX products with functionalities and user experiences nearly equivalent to CEXs can be created.
