Key highlights:
- BNB Chain is building a new Layer 1 blockchain that will run side by side with Binance Smart Chain (BSC). Both networks will keep running on their own.
- This new network aims for block times of 200 milliseconds and transaction pre-confirmations in about 20 milliseconds.
- BNB will stay as the main token for paying fees, staking, and governance, there’s no plan to launch a separate token for the new chain.
- A private development network has already started running. BNB Chain expects to open the public testnet in late 2026, with the mainnet launch targeted for early 2027.
BNB Chain is getting ready to grow its blockchain system by adding a new Layer 1 network. This chain is focused on speed, finance-related apps, and instant transactions. Binance founder CZ confirmed the news, which also appears in updated BNB Chain documents. The project isn’t meant to replace Binance Smart Chain, it’s about running them side by side and giving developers a platform built for fast transactions. The idea is to meet the strict demands of high-speed trading and payment applications
Lately, platforms like Hyperliquid, Lighter, and Aster are drawing more attention in decentralized exchange markets, especially for perpetual contracts. With competition increasing, BNB Chain is jumping in with a new network for high-speed trading, on-chain order books, and payment tools, all powered by BNB as the ecosystem’s main token.
A New Blockchain Designed for Speed
BNB Chain’s upcoming Layer 1 is being built with different performance goals than a general-purpose blockchain. Reports say the team aims for block times around 200 milliseconds and pre-confirms transactions in about 20 milliseconds.
These numbers matter for trading and payments, where every millisecond counts. High-frequency trading needs almost instant execution, and real-time payment systems need fast processing. If you’re dealing with on-chain order books, you need a blockchain that can keep up with heavy trading activity, too.
By aiming for these speeds, BNB Chain clearly wants to fill that gap. Still, these figures are targets, not final, live results. We haven’t yet seen independent tests confirm this level of performance.
The move also shows BNB Chain is trying to strengthen its technology for financial use cases. Faster block times and confirmations suggest it’s aiming to support apps that can’t afford delays.
BNB Smart Chain Will Continue Operating
One important part of the plan is that the new Layer 1 will not replace Binance Smart Chain. Instead, both blockchains will keep working, each serving different needs. The old network will remain for general use, while the new chain targets fast, demanding apps. BNB will stay as the native token for both networks. There are no plans to launch a new coin just for fees or governance. BNB will handle everything, including fees, staking, and decision-making.
The network is also expected to connect with BNB Smart Chain through a native bridge. That way, they can work together as part of one big ecosystem. So, while there are two blockchains, there’s still just one main token. Other features are coming too, like native account abstraction and on-chain privacy pools. But for now, they haven’t shared technical details about those.
Development Timeline and Market Interest
Development has already started, with an internal testnet running among multiple validators, indicating progress beyond the planning stage. BNB Chain is planning to launch the public testnet in late 2026, with the mainnet coming in early 2027. That’s the current roadmap, though neither milestone has happened yet.
Crypto community members are already interested, especially those tracking possible airdrops or incentives for joining testnets. A new blockchain often brings a wave of people looking to try out apps early. But so far, there’s no official word about airdrops or guaranteed rewards for testers.
Traders are also watching closely to see how this move could affect BNB prices or derivatives markets. Much depends on how well the new infrastructure works and whether developers adopt it for real projects.
Right now, BNB Chain has a clear plan: build a high-speed network for finance and trading, keep the BNB token at the center, and run both blockchains together. Whether it pays off depends on how the network performs and who’s willing to use it.
