BNB Chain Plans New Layer 1 Blockchain With 200ms Block Times, Targeting 2027 Launch
BNB Chain is planning a new Layer 1 blockchain designed to operate alongside BNB Smart Chain (BSC), with BNB remaining the network's token for transaction fees, staking, and governance. According to updated BNB Chain documentation cited in a report by Wu Blockchain, the proposed network targets block times of approximately 200 milliseconds and pre-confirmation times of around 20 milliseconds.
The initiative would expand the BNB Chain ecosystem without introducing a separate token. An internal development network using multiple validators is already operational, while a public testnet is scheduled for late 2026 and the mainnet launch is expected in early 2027.
New BNB Chain Layer 1 to Run Alongside BSC
The planned blockchain is intended to operate in parallel with the existing BNB Smart Chain, rather than replace it. The approach would allow the ecosystem to add another blockchain infrastructure layer while continuing to use BNB for its core network functions.
The project was also highlighted by crypto commentator Wu Blockchain, which referenced confirmation from Binance founder Changpeng Zhao, commonly known as CZ. The available source material does not provide further technical details about how the two networks will communicate or how users and applications may move between them.
Network Targets Faster Block and Pre-Confirmation Times
BNB Chain's updated documentation reportedly outlines a target block time of approximately 200 milliseconds and a pre-confirmation time of around 20 milliseconds. These figures describe the planned network's performance targets; they do not establish measured performance on a public testnet or production network.
The project is intended to expand the ecosystem's infrastructure and interoperability capabilities. However, further technical information would be needed to assess how the new chain will integrate with existing applications and the broader BNB Chain environment.
Public Testnet Expected in Late 2026
The development roadmap identifies late 2026 as the target period for the public testnet, followed by an expected mainnet launch in early 2027. An internal multi-validator development network is already running, according to the supplied report.
These milestones remain planned targets. The available information does not confirm a specific public testnet date or a finalized mainnet launch date.
What the New Blockchain Could Mean for BNB
Under the proposed design, BNB would continue to serve as the asset used for gas fees, staking, and governance, avoiding the introduction of a separate native token for the new network.
The project could add another infrastructure option for the BNB Chain ecosystem, which has also focused on areas such as tokenized assets. Its eventual impact will depend on technical execution, adoption by developers and users, and how the new network works alongside BSC.
Market implications remain uncertain. The source material does not provide verifiable trading-volume figures or evidence that the announcement has already changed BNB market activity. Traders and developers will have clearer information to evaluate as the project approaches its planned testnet and mainnet milestones.
