BNB Chain has already lifted performance on BNB Smart Chain. During the first half of 2026, block times fell to 450 milliseconds from 750, while benchmark throughput rose to about 5,200 transactions per second from roughly 2,800.
David Z, BNB Chain’s chief technical officer, told CoinDesk the next phase focuses on execution rather than consensus.
“All smart contracts today need optimization directly at the execution layer,” he said. “The chains got fast at consensus and storage, but the execution engine itself still works like it’s translating sentence by sentence.”
The new network will use execution-layer techniques such as just-in-time compilation, which compiles code as it runs, and strength reduction, which swaps expensive calculations for simpler ones.
The roadmap also reserves blockspace for services such as oracles, liquidations and cross-chain bridges, alongside native privacy, account abstraction, gas sponsorship, transaction batching, scheduled execution and passkey signing.
BNB Chain is separately researching quantum-resistant security. The team said it aims to let users adopt quantum-safe protection without changing wallet addresses or disrupting existing applications, work that remains at the research stage.
