BNB Chain launches layer-1 for AI agents with quantum security
BNB Chain plans a new layer-1 for AI-driven and high-frequency transactions with quantum-resistant security, targeting 100,000+ TPS and a testnet by late 2026.
BNB Chain announced plans to build a new layer-1 blockchain aimed at AI-driven transactions and high-frequency trading. The project targets more than 100,000 transactions per second, transaction confirmation under 50 milliseconds and block finality in under one second. A testnet is scheduled for late 2026 with a mainnet planned for early 2027, according to the H2 2026 technical roadmap.
The new chain will run alongside the existing BNB Chain rather than replace it. Developers say the design will process multiple transactions in parallel and change how transaction data is stored and verified to reach the performance goals. The roadmap lists tools for AI agents, privacy features and protocol improvements to support automated trading and payments.
A key technical feature called TxStream removes the public mempool where pending transactions are normally visible and forwards transactions directly to block leaders. Developers expect that approach to reduce latency and limit opportunities for front-running, where actors exploit visible pending transactions.
Work earlier in 2026 shortened block intervals from 750 milliseconds to 450 milliseconds and raised benchmark throughput from about 2,800 transactions per second to roughly 5,200. The roadmap calls for further increases in throughput and measures to reduce congestion between applications.
The project includes research on quantum-resistant security. The team is testing hybrid approaches that combine classical and quantum-safe algorithms to protect data encrypted today from being decrypted by future quantum computers. Developers are exploring account abstraction as a way for users to upgrade cryptographic protections without changing wallet addresses.
The roadmap describes the effort as ongoing research and engineering through 2026, with an architecture intended to accept future upgrades without disrupting existing wallets or applications. “There’s no finish line here. Quantum computing will keep evolving, and so will our testing and research,” the developers wrote.
The announcement comes as multiple companies and consortia build infrastructure and standards to let software agents transact autonomously, pay for APIs and services, and manage funds within set limits. BNB Chain’s plan adds a layer focused on lower latency and higher throughput for those use cases.
