“Six months ago, BNB Chain set three priorities for BSC: speed, throughput, and protocol stability,” the developers wrote. “This roadmap opens with the receipts and closes with what comes next—a second half focused on doubling performance again, and an architecture designed for the decade ahead.”
According to BNB Chain, the new network is being built to eventually handle more than 100,000 transactions per second by processing multiple transactions at once and improving how data is stored and verified. The developers said it is also aiming to confirm transactions in less than 50 milliseconds and finalize blocks in under one second.
A major component of the new layer-one is TxStream. This system removes the public mempool where pending blockchain transactions are typically visible before confirmation and sends transactions directly to block leaders to reduce latency and limit front-running opportunities.
According to BNB Chain, upgrades to BNB Smart Chain during the first half of 2026 reduced block intervals from 750 milliseconds to 450 milliseconds and increased benchmark throughput from roughly 2,800 transactions per second to 5,200. The developers said its next phase will focus on further increasing throughput, reducing congestion between applications.
Beyond speed improvements, BNB Chain said it is researching quantum-resistant security as developers prepare for future threats from quantum computers.
BNB Chain said its quantum security research focuses on protecting against future threats where more advanced quantum computers could decrypt encrypted data collected today. The developers said it is testing hybrid protections and ways for users to adopt quantum-safe security without changing wallet addresses.
“There's no finish line here. Quantum computing will keep evolving, and so will our testing and research,” they wrote. “The point is that when it matures, BNB Chain's infrastructure is already prepared.”
BNB Chain did not immediately respond to a request for comment by Decrypt.
The news comes as crypto and technology companies are building infrastructure for AI agents that can move money and execute transactions without constant human approval.
