BNB Chain has already improved performance on BNB Smart Chain. During the first half of 2026, blocking times fell from 750 to 450 milliseconds, while baseline throughput increased to about 5,200 transactions per second from about 2,800.
David Z, CTO of BNB Chain, told CoinDesk that the next phase is focused on execution rather than consensus.
“All current smart contracts need direct optimization at the execution layer,” he said. “The chains were sped up in consensus and storage, but the execution engine still works as if it were translating phrase by phrase.”
The new network will use runtime layer techniques such as just-in-time compilation, which compiles code as it runs, and force reduction, which trades expensive calculations for simpler ones.
The roadmap also reserves block space for services such as oracles, settlements, and cross-chain bridges, along with native privacy, account abstraction, gas sponsorship, transaction batching, scheduled execution, and access key signing.
BNB Chain is separately investigating quantum-resistant security. The team said its goal is to allow users to adopt quantum-safe protection without changing wallet addresses or disrupting existing applications, work that is still in the research stage.
