BNB chain is building new blockchain for trading agents

​BNB Chain is developing a new Layer 1 blockchain focused on agentic trading and faster onchain trading. The project has, for the first time, disclosed the architecture of the network, which the team has been working on for several months.

According to The Block, the new network will become part of the existing BNB Chain ecosystem and will operate alongside BNB Smart Chain, opBNB and Greenfield. Under the technical roadmap for the second half of 2026, the project aims to achieve transaction preconfirmation in less than 50 milliseconds.

The main goal of the new architecture is to bring the user experience closer to that of centralized exchanges while preserving the key advantages of the onchain environment: self-custody of assets, transparency and final settlement confirmation on the blockchain.

Problems with onchain trading

BNB Chain acknowledges that it is not yet possible to fully match the speed of a centralized exchange. Centralized platforms execute orders in microseconds. However, the team believes most users do not feel the microsecond difference in practice.

According to BNB Chain Chief Technology Officer David Z, real-world latency for traders is usually measured in milliseconds. Therefore, the team estimates that preconfirmation in less than 50 milliseconds falls within the range that an ordinary user perceives as an almost exchange-like experience.

High-frequency trading remains the exception. In this segment, centralized exchanges still have an advantage. But for other users, the new network is expected to offer an experience close to a CEX without custodial risk.

How the new network will work

One of the key elements of the architecture will be TxStream. This feature removes the public mempool and routes transactions directly to the block leader. This approach is designed to reduce latency and make common forms of front-running, including sandwich attacks, more difficult.

According to David Z, if there is no public mempool, an attacker does not get a window in which they can see a pending trade and build a sandwich attack around it. The transaction order is fixed before other participants learn about the operation itself.

At the same time, this model raises another question: whether the block leader becomes a new point for MEV extraction or censorship. BNB Chain says this risk is reduced through rapid leader rotation every 200 milliseconds. According to the CTO, this is not enough time for a validator to build a sustainable business model around abusing its position.

In addition, preconfirmations in less than 50 milliseconds make validator behavior publicly verifiable. Violations could put their stake and reputation at risk.

“TxStream does not eliminate MEV. Nothing does. But it makes the dominant attacks practically impossible by design,” David Z said.

Another component will be PriorityLane. It will reserve part of the block space for oracles, liquidations and bridges. Governance of this mechanism is planned to be onchain.

Speed and launch targets

BNB Chain expects the new network to be able to process more than 100,000 transactions per second. The team plans to achieve this through joint optimization of consensus, parallel execution and LtHash-based storage. Block finality of less than one second is also planned.

However, these are still only design targets. The new network has not yet reached testnet. The team plans to launch the testnet by the end of 2026, with the mainnet release expected in early 2027.

BNB Chain believes the main performance problem lies not so much in consensus or data storage, but in the execution layer. According to David Z, EVM networks perform too much repeated work because the same popular contracts, such as DEX swaps or token transfers, are run millions of times.

To address this problem, the team is betting on just-in-time compilation, a technique long used in traditional software development, and strength reduction. In essence, this is about technical compiler optimization rather than loud architectural promises.

A separate risk is the potential fragmentation of liquidity within the BNB Chain ecosystem itself. In response, the CTO said the new network will have an official native bridge to BSC. At the same time, BSC will serve as the settlement hub, while BNB will remain the unified asset across all chains in the ecosystem.

“The goal is to grow the overall BNB Chain pie, not to slice it differently,” David Z said.

According to him, the new network is not meant to replace BNB Smart Chain, but to complement it. It will focus on use cases for which the older network was not originally built, rather than simply moving BSC’s mature DeFi ecosystem into a new environment.

The new network will become the fourth element of the BNB Chain stack alongside BNB Smart Chain, opBNB and Greenfield. The company presents this expansion as a way to give developers more flexibility, rather than an attempt to force projects to migrate to new infrastructure.

BNB Chain’s roadmap comes amid a broader race among high-performance blockchains. Solana with Firedancer, Monad, MegaETH and other projects are also trying to remove execution-layer bottlenecks, improve parallelization and sharply increase network throughput.

How BNB chain differs from other blockchains

BNB Chain differs from many other blockchains because it was initially built around the large Binance exchange ecosystem and the BNB token. This gave the network a strong user base, high liquidity and a large number of applications in DeFi, GameFi, NFTs and payments. Unlike Ethereum, where the main focus is often on maximum decentralization and base-layer security, BNB Chain has historically emphasized lower fees, faster transactions and convenience for mass users.

Another difference is BNB Chain’s multi-layer structure. The ecosystem includes BNB Smart Chain for smart contracts, opBNB for scaling, Greenfield for decentralized data storage and now a separate Layer 1 network for faster onchain trading. This approach shows that BNB Chain is trying to compete not only with Ethereum, Solana or other L1 networks, but also with centralized exchanges by offering developers and traders infrastructure with high throughput, fast execution and self-custody of assets.

As a reminder, activity on BNB Chain increased thanks to memecoins on PancakeSwap.
