BNB Chain targets AI trading with 100,000 TPS blockchain
BNB Chain is building a dedicated high-speed blockchain capable of 100,000 transactions per second to capture the emerging market for autonomous AI trading, setting a new benchmark in the crypto arms race to match traditional finance speeds.
BNB Chain unveiled plans on Wednesday for a new layer-1 blockchain designed specifically for high-frequency trading and AI-driven transactions. The network will operate alongside the existing BNB Chain rather than replacing it, with a testnet scheduled for late 2026 and a mainnet launch targeted for early 2027.
Developers are targeting speeds that rival traditional financial infrastructure. The new chain aims to process over 100,000 transactions per second, confirm transactions in under 50 milliseconds, and finalize blocks in less than a second. “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.”
The current BNB Smart Chain recently increased its benchmark throughput from roughly 2,800 transactions per second to 5,200, while cutting block intervals from 750 milliseconds to 450 milliseconds. To push far beyond these figures, the new layer-1 will utilize a system called TxStream. This mechanism removes the public mempool—where pending transactions are usually visible—and sends orders directly to block leaders to reduce latency and curb front-running.
Future-proofing infrastructure
Beyond raw speed, the roadmap includes research into quantum-resistant security. Developers are testing hybrid protections using account abstraction, which allows users to adopt quantum-safe security without changing their wallet addresses. “There's no finish line here. Quantum computing will keep evolving, and so will our testing and research,” they wrote.
An industry race
The move reflects a broader push to build infrastructure for autonomous AI agents that can move money and execute trades without constant human approval. Stripe-backed Tempo launched a payments-focused layer-1 in March, while MoonPay introduced an open wallet standard for AI agents that same month.
Major technology and finance firms have quickly followed. In May, Amazon Web Services partnered with Coinbase and Stripe to let AI agents pay for APIs and data feeds using USDC stablecoins. Coinbase then launched a dedicated tool in June for AI agents to trade crypto and manage portfolios within user-defined limits.
For investors, BNB Chain’s roadmap signals that the infrastructure phase of the machine-to-machine economy is accelerating. Blockchains are actively competing to become the high-speed settlement layer for AI-driven finance.
