- BNB Chain is developing a new Layer 1 blockchain built specifically for high-speed agentic trading.
- The network aims to deliver transaction preconfirmation in under 50 milliseconds while preserving on-chain transparency.
- A new transaction system is designed to reduce latency and limit MEV attacks such as sandwich trading.
BNB Chain has revealed new details about its upcoming Layer 1 blockchain, a network designed specifically to support the next generation of agentic trading. After months of research and development, the project has entered a new phase, with developers outlining how the blockchain will operate alongside the existing BNB Chain ecosystem rather than replacing it.
The announcement highlights BNB Chain’s growing focus on building infrastructure capable of supporting increasingly automated trading strategies while maintaining the benefits of decentralized finance.
Built for Ultra-Fast Trading
According to BNB Chain‘s technical roadmap for the second half of 2026, the new blockchain is designed to achieve transaction preconfirmation in less than 50 milliseconds.
The goal is to deliver an execution experience comparable to centralized cryptocurrency exchanges while preserving self-custody and the transparency that comes with on-chain transactions. Faster execution could become increasingly important as algorithmic trading, AI-powered agents, and automated financial applications continue gaining popularity.
By operating as a separate Layer 1 network, the chain will complement the existing BNB ecosystem while targeting users who require extremely low-latency execution.
New Transaction System Targets MEV
One of the biggest architectural changes involves eliminating the traditional public mempool. Instead, BNB Chain plans to introduce a new transaction transmission protocol known as TxStream.
Rather than broadcasting pending transactions across a public network, TxStream will send transactions directly to block producers. This approach is intended to significantly reduce transaction delays while minimizing opportunities for Maximal Extractable Value (MEV) strategies.
The design specifically targets practices such as sandwich attacks, where automated bots exploit pending transactions to profit at the expense of other traders.
AI and Agentic Trading Drive Development
The new blockchain reflects the growing demand for infrastructure capable of supporting autonomous trading agents and AI-powered financial applications.
As decentralized finance evolves, developers increasingly require networks that can process large volumes of transactions with minimal delay while maintaining security and transparency. BNB Chain believes its specialized Layer 1 can provide the speed needed for these advanced trading systems without sacrificing decentralization.
The project also signals a broader trend toward purpose-built blockchains optimized for specific use cases rather than relying on a single network to handle every application.
BNB Chain Expands Its Ecosystem
Instead of replacing the current BNB Chain, the new Layer 1 will operate in parallel, giving developers additional options depending on their performance requirements.
While the network remains under development, its focus on ultra-fast execution, reduced MEV exposure, and AI-driven trading positions it as one of BNB Chain’s most ambitious infrastructure projects to date. Investors and developers will be watching closely as more technical details emerge and the blockchain moves closer to launch.
