BNB Chain unveils agentic trading Layer 1 targeting sub-50-millisecond preconfirmation

The proposed chain would run alongside BNB Smart Chain as BNB Chain targets more than 100,000 transactions per second, sub-second finality, protocol-level privacy and a testnet launch by late 2026.

Fact Check
The official BNB Chain H2 2026 Tech Roadmap blog directly confirms every element of the claim: a next-generation Layer 1 architecture for agentic trading with 100K+ TPS, sub-50ms pre-confirmations, sub-1-second finality (a high-speed trading chain), plus H2 2026 plans to double BSC mainnet throughput and develop the next-gen L1. The Block reporting, Odaily, and BlockBeats independently corroborate the sub-50ms preconfirmation target, TxStream mempool elimination, testnet end-2026, and mainnet early-2027 timeline. All sources are consistent with no conflicts.
Summary

BNB Chain is expanding plans for a separate Layer 1 blockchain aimed at high-frequency trading, autonomous AI-agent payments and institutional activity, adding protocol-level privacy and a longer-term goal of reaching 1 million transactions per second. The network is positioning the new chain as an addition to its existing stack rather than a replacement for BNB Smart Chain, with a testnet scheduled for late 2026 and mainnet planned for early 2027. The proposed architecture starts with a target of more than 100,000 transactions per second, transaction preconfirmations below 50 milliseconds and block finality in less than one second, using co-optimized consensus, parallel execution and LtHash-based storage. BNB Chain said the longer-term design goal is 1 million TPS, a scale it argues is needed for machine-to-machine commerce, automated trading and institutional settlement. A central feature is TxStream, which removes the public mempool and routes transactions directly to the block leader to reduce latency and limit front-running risk. The roadmap also includes PriorityLane to reserve block space for critical operations such as oracle updates, bridge transactions and liquidations during periods of stress, as well as an account abstraction suite for sponsored gas, batched transactions, scheduled execution and passkey signing. The expansion comes as BNB faces market and usage pressure. CryptoSlate data showed BNB was down more than 35% this year at $563, its lowest valuation since October 2024, while Artemis data showed BNB Chain transactions fell 12.5% in the first quarter even as Solana and Ethereum rose 46.4% and 38%. BNB Chain is also developing confidential transactions and selective disclosure, with zero-knowledge proofs expected to play a central role so users can keep sensitive data private while still supporting audits, compliance checks or regulatory reporting. The privacy push is aimed at institutions moving tokenized assets, collateral or trading inventory on-chain, while also addressing broader demand from crypto users for more financial confidentiality. Developers are also researching post-quantum protections through hybrid cryptography and account abstraction as part of the network’s longer-term security strategy.

Terms & Concepts
  • zero-knowledge proofs: A cryptographic method that can prove a transaction or compliance check is valid without revealing the underlying data.
  • mempool: The pool of pending blockchain transactions that can usually be seen before they are confirmed.
  • account abstraction: A blockchain design approach that allows more flexible wallet controls, such as sponsored fees and custom permission settings.
