BNB Chain revealed new details about its future layer 1 blockchain focused on agentic trading, an infrastructure designed to deliver faster operations without compromising the transparency of on-chain transactions. The project is part of the network’s technology roadmap for the second half of 2026 and is expected to reach the mainnet in early 2027.
The proposal is to complement BNB Chain’s current infrastructure, providing an experience close to that of a centralized exchange, but keeping user self-custody of assets. The new network was designed to deliver transaction pre-confirmations in less than 50 milliseconds, significantly reducing the response time perceived by investors.
According to David Z, technology director at BNB Chain, the practical difference between a centralized exchange and a blockchain lies in the real user experience. "For high-frequency trading (HFT) in co-located facilities, a centralized broker (CEX) is still the best option today. For everyone else, this is the experience of a CEX without custody risk."
To achieve this performance, the team developed an architecture that removes the public mempool through a feature called TxStream. Instead of waiting in a public queue, transactions are sent directly to the leader responsible for block production, reducing delays and making known attacks such as "sandwich"—used to exploit pending operations—more difficult.
David Z highlighted that the technology does not completely eliminate MEV (Maximal Extractable Value), but drastically reduces the most common forms of exploitation. "TxStream does not eliminate MEV. Nothing does. It makes dominant attacks impractical by design."
Another feature presented is PriorityLane, a mechanism that will reserve space in blocks for applications considered critical, such as oracles, automated liquidations, and bridges between blockchains. The administration of that space will be handled directly within the network itself through on-chain governance.
BNB Chain has also set a goal of exceeding 100 thousand transactions per second using parallel execution, optimized consensus, and storage based on LtHash. In addition, block finalization time should be kept below one second, bringing the experience even closer to traditional trading platforms.
Public tests for the new blockchain are planned for the end of 2026. If the schedule is maintained, the definitive implementation will take place in the first months of 2027.
The CTO explained that the main challenge faced by blockchains compatible with the Ethereum Virtual Machine (EVM) is on the execution layer, responsible for repeating similar operations millions of times in smart contracts. To reduce this bottleneck, the team is adopting just-in-time compilation techniques and other optimizations known in software engineering.
Integration with BNB Smart Chain is also part of the strategy. Instead of fragmenting the ecosystem’s liquidity, the new blockchain will have an official native bridge, using BNB as the common asset across all networks in the BNB Chain structure.
"The goal is to increase the total pie of BNB Chain, not fragment it again", Z said.
In addition to the new layer 1, developers continue researching quantum-computation-resistant security solutions. The strategy combines post-quantum algorithms with the current infrastructure, enabling a gradual migration without requiring changes to users’ wallet addresses.
"Nobody in the industry yet has a complete quantum migration scheme, including nodes", Z said.
With the arrival of the new blockchain, the BNB Chain structure will include four integrated networks: BNB Smart Chain, opBNB, Greenfield, and the future layer 1 focused on agentic trading, expanding options for developers and high-performance-focused applications.
