BNB Chain has already boosted the performance of BNB Smart Chain. During the first half of 2026, block time dropped to 450 milliseconds from 750, while benchmark throughput increased to around 5,200 transactions per second from around 2,800.
David Z, BNB Chain’s chief technical officer, told CoinDesk that the next phase focuses on execution rather than consensus.
“All smart contracts today need optimization directly at the execution layer,” he said. “The chains became fast for consensus and storage, but the execution engine itself still works as if 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 trades expensive computations for simpler ones.
The roadmap also reserves block space for services such as oracles, liquidations, and cross-chain bridges, along with built-in privacy, account abstraction, gas sponsorship, transaction batching, scheduled execution, and access key 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.
