BNB Chain has announced plans to launch a new layer-1 blockchain specifically designed to accommodate the demands of AI agents and future quantum computing threats. The initiative aims to significantly enhance transaction speeds and efficiency, targeting over 100,000 transactions per second with sub-second finality, a stark contrast to current blockchain capabilities.
The new network, detailed in BNB Chain's H2 2026 technical roadmap, is slated for a testnet launch by the end of 2026 and a mainnet release in early 2027. This development is part of a broader strategy to double performance and build an architecture for the coming decade, following earlier upgrades that reduced block intervals and increased throughput.
A key innovation will be TxStream, a system designed to remove the public mempool, thereby reducing latency and limiting front-running opportunities by sending transactions directly to block leaders. Beyond speed, BNB Chain is actively researching quantum-resistant security measures, exploring account abstraction to allow users to upgrade security without changing wallet addresses, preparing for potential future decryption threats from advanced quantum computers.
This move by BNB Chain aligns with a growing trend in the crypto and tech industries to build specialized infrastructure for AI agents capable of autonomous financial transactions. Companies like Stripe-backed Tempo, MoonPay, Amazon Web Services, and Coinbase have recently launched or partnered on initiatives to enable AI agents to execute trades, make payments, and manage portfolios across various blockchains.
