BSC's move to shorten block intervals demonstrates the future technical roadmap. A block time of 0.45 seconds is not just a number—it means transactions can be confirmed more quickly, enhancing user experience. Decentralized applications previously limited by confirmation delays now have new possibilities. But what is the cost behind this? Faster block production demands more stringent requirements on network node synchronization efficiency, transaction ordering stability, and on-chain execution concurrency. Performance, timing, and execution efficiency must be optimized together; otherwise, it's just empty talk. This is also why each performance upgrade is not a simple parameter adjustment but a systemic engineering effort involving the underlying architecture.
