Overview
- BNB Chain updated technical documentation on Thursday that lays out NewL1, an EVM‑compatible Layer‑1 designed for extreme low latency and high throughput.
- The design sets concrete performance targets including 200 millisecond block intervals, roughly 20 millisecond pre‑confirmations, sub‑second finality, and an overall throughput goal above 100,000 transactions per second.
- NewL1 runs today as an internal multi‑validator devnet with a public testnet planned for late 2026 and a targeted mainnet launch in early 2027.
- Key architecture choices include an enhanced Parlia consensus with BLS voting, separation of ordering from execution, a Multi‑Lane processing model, native account abstraction, and an optional shielded privacy pool.
- Critical pieces remain unfinished and risky: the native bridge is incomplete, the shielded pool needs trusted setup and audits and should not be used with real funds, and devnet results may not hold under public, adversarial conditions.
