1. What is the new BNB Chain layer-1?
BNB Chain is developing a second layer-1 blockchain, provisionally named NewL1, that is designed to deliver the speed usually associated with centralized exchanges. Updated documentation published on October 22, 2026 describes an EVM-compatible network that targets more than 100,000 transactions per second and finality in under one second, with a public testnet expected by the end of 2026.
A layer-1 is a base blockchain that validates and settles its own transactions, as opposed to a layer-2 network that builds on another chain. EVM compatibility means the network is meant to run the same smart contracts and use the same developer tools as Ethereum-style systems, which lowers the effort required for existing applications to move over.
The project is aimed at workloads where delay is costly. The documentation names latency-sensitive uses such as high-frequency trading and activity driven by artificial intelligence, both of which depend on fast, predictable confirmation of orders and payments.
In the plans described so far, NewL1 is an addition to the BNB Chain ecosystem and not a replacement for it. The stated aim is to extend the existing infrastructure without disrupting the frameworks developers already use, including BNB Smart Chain.
2. What performance targets has BNB Chain set?
The headline figure is throughput above 100,000 transactions per second. The research behind the project attributes that goal to two techniques: optimizing the consensus process, which is how validators agree on the next block, and executing transactions in parallel instead of one after another.
The second target is finality in under one second. Finality is the point at which a transaction can no longer be reversed. On many networks it takes several seconds or even minutes, and shortening it is essential for traders who need to know that a fill is permanent before they place the next order.
The documentation also discusses pre-confirmation, an early signal that a transaction is likely to be included in a block before it is locked in. Such signals let applications respond almost immediately, even though the final settlement arrives slightly later.
The plan keeps a familiar foundation for agreement among validators. BNB Chain intends to use an enhanced version of Parlia, the consensus mechanism that the existing chain already relies on, which suggests an evolution of proven components rather than a complete redesign.
These numbers are goals, not measured results. They describe what the team is trying to reach, and the gap between a target in a design document and performance on a live network can be wide.
3. Why is BNB Chain targeting exchange-like speed?
The motivation is competitive. Centralized exchanges match orders in a tiny fraction of the time that public blockchains need, and traders who lose orders to failed transactions during volatile markets have a strong reason to stay on those platforms. The documentation reads as a response to that frustration, a wish list for users who have seen orders fail when prices move quickly.
NewL1 was first outlined in BNB Chain's technical roadmap for the second half of 2026, published on July 8, 2026. That roadmap argued that on-chain infrastructure has to compete with centralized exchanges on performance if decentralized trading is going to attract serious volume.
The October update builds on that earlier outline by adding specific technical goals. Moving from a general ambition to named targets for throughput and finality gives developers and validators something concrete to evaluate and, eventually, to test.
If the targets are met, trading on-chain could feel much closer to using a centralized venue while assets remain in the user's own custody. That combination of speed and self-custody is the central selling point, because it would remove one of the main reasons traders accept the counterparty risk of exchanges.
Speed matters in this context because of how markets work. A trader who sends an order during a sharp price swing needs it to be processed before conditions change, and a network that confirms transactions slowly can leave that order stuck or executed at a worse price. Reducing that delay is therefore as much about trust in the trading venue as it is about raw technical performance.
4. How do AI agents fit into the plan?
The roadmap explicitly names users of autonomous trading and AI applications as a core audience. Software agents that act on their own need quick and predictable settlement, because they may issue many small transactions in succession and cannot easily wait for slow confirmation.
For a human trader, an occasional delay is an annoyance. For an automated system that adjusts positions or pays for services continuously, delay can break the logic of the strategy. A network with sub-second finality and high throughput would be better suited to that pattern of use.
This focus places NewL1 within a wider trend in which blockchain developers are pitching their networks as infrastructure for machine-driven finance. The pitch depends on whether agents actually transact on-chain in meaningful numbers, which remains an open question across the industry.
BNB Chain's documentation treats the combination of fast trading and AI activity as one design problem. Both need low latency, reliable ordering and enough capacity to handle bursts of demand, and a single high-performance chain could in principle serve both.
5. How does NewL1 relate to BNB Smart Chain?
BNB Smart Chain, often abbreviated BSC, is the network where most of the ecosystem's applications and users currently operate. The plan for NewL1 does not ask them to leave. It is framed as a complementary network designed to extend what the ecosystem can do.
Running two layer-1 networks raises practical questions that the documentation will need to address over time, including how assets and messages move between them, how validators are organized and how developers choose where to deploy. The early material is focused on performance goals more than on those operational details.
The shared EVM foundation should ease some of that complexity. Applications written for one EVM network can usually be adapted to another with modest changes, and wallets and developer tools tend to work across such chains without special support.
Keeping the existing network intact also limits risk. Users and projects that depend on BSC can continue as before while the new chain matures, and they can decide later whether its speed advantages justify moving some activity.
6. What is the development status and timeline?
NewL1 is not yet open to the public. It currently runs as an internal development network with multiple validators, described as operating as of October 2026. That stage allows engineers to test the design in a controlled setting before outside participants are involved.
BNB Chain has said it plans to release a public testnet by the end of 2026, followed by a full mainnet launch in early 2027. A testnet is a public network that uses tokens without real value, giving developers and validators a place to experiment and uncover problems before money is at stake.
Those dates are targets. Blockchain projects often adjust schedules as testing reveals issues, and the interval between an internal network and a stable mainnet can be longer than first projected.
For now, the available information comes from documentation and roadmap material, not from independent benchmarks. Nobody outside the project has yet measured how the network behaves under load, and that absence is important context for the figures quoted above.
The distinction between an internal network and a public one is significant. An internal network is run by known operators who coordinate closely, so it avoids many of the problems that appear when unrelated parties join. Moving to a public testnet is the first moment when the design must cope with participants whose behavior the team cannot control.
7. What risks and open questions remain?
The biggest uncertainty is whether results from a development network will hold up on a public one. Performance measured among a small group of cooperating validators can differ sharply from performance in an open system, where participants may act adversarially and demand can spike unpredictably.
Throughput of more than 100,000 transactions per second is also a theoretical ceiling in many designs. Real-world usage depends on the types of transactions, how much of them can be processed in parallel and how well the network copes with congestion on popular applications.
Security is a related concern. Faster block production and shorter finality place greater demands on validators and on the software they run, and any shortcut that speeds up agreement must not weaken the guarantees that users depend on. The documentation will be judged on how it handles those trade-offs.
There is also the matter of adoption. Even a technically strong chain needs liquidity, applications and users, and traders will move only if the experience is demonstrably better than what they already have.
8. What to watch next for NewL1
The first milestone is the public testnet, which BNB Chain expects before the end of 2026. Its arrival would let outside developers and analysts verify the project's claims for the first time, rather than relying on the team's own descriptions.
The second is the measured performance on that testnet. Observers will compare actual block and finality times against the sub-second goal and check whether sustained throughput approaches the 100,000 transactions per second target under realistic conditions.
The third is the mainnet window in early 2027. A launch on schedule, with the performance and stability the documentation promises, would put BNB Chain in a stronger position to compete for latency-sensitive trading and AI-driven activity. A delay or a gap between target and result would temper those expectations.
Until those steps are completed, NewL1 is best understood as a statement of direction, one that sets out how BNB Chain wants to narrow the gap between decentralized and centralized trading.
