BNB Chain Develops NewL1 Alongside BNB Smart Chain

BNB Chain is developing NewL1, a separate blockchain intended to operate alongside BNB Smart Chain, with BNB remaining the sole token for fees, staking and governance across the networks. The proposal, described in technical documentation updated October 22, is still at the development-network stage; a public testnet is planned for late 2026 and a mainnet for early 2027. The network is designed as an Ethereum Virtual Machine-compatible Layer 1 for applications that BNB Chain says need faster or more predictable transaction processing. The documentation sets a target block interval of 200 milliseconds and transaction preconfirmations at about 20 milliseconds. Those are development targets, not demonstrated results on a public network, and the documentation notes that a preconfirmation can be revoked before a transaction is finalized. BNB Chain’s proposed design separates transaction ordering from execution and includes a version of its Parlia consensus mechanism and a system called MultiLane, intended to reserve processing capacity for different types of transactions. The documentation identifies high-frequency trading, decentralized order books and payments among potential...
