BNB Chain has reported a sharp increase in BSC Testnet throughput after deploying BEP-675, an upgrade designed to eliminate redundant execution during block processing. The network said throughput rose from 1,237 to 2,324 transactions per second, an 88% improvement, while leaving the existing block interval unchanged.
The result is notable because the gain did not come from accelerating block production. BNB Chain said the test maintained the network’s 450ms block interval and existing finality lag, meaning the additional capacity came from making execution more efficient rather than compressing the chain’s timing parameters.
BEP-675 targets duplicated execution work
In its official BEP-675 technical update, BNB Chain said the improvement was achieved by reducing duplicated work performed during block execution. Removing redundant processing allowed the testnet to handle substantially more transactions without altering its underlying block cadence, according to the project.
That distinction matters when assessing the nature of the performance gain. Increasing throughput by shortening block intervals can place additional pressure on infrastructure and network synchronization, while optimizing execution seeks to extract more capacity from the existing operating model. BEP-675 instead focuses on reducing unnecessary computational work inside the execution process, allowing more transactions to be processed within the same timing framework.
The upgrade remains a testnet development rather than a confirmed mainnet performance improvement. BNB Chain has presented the figures as results from BSC Testnet, so the 2,324 TPS figure should not be treated as evidence that identical throughput is already available under mainnet conditions.
Mainnet performance remains the key test
For BNB Chain, the result adds to its broader effort to expand BSC capacity while preserving predictable block production and finality characteristics. An 88% testnet improvement without changing block timing suggests execution optimization could provide additional headroom without relying solely on faster blocks.
The next question is whether the efficiency gains remain consistent under real-world mainnet workloads, where transaction mixes, validator conditions and demand can differ from controlled test environments. The practical value of BEP-675 will ultimately depend on whether its testnet gains translate reliably into production conditions.
The upgrade represents a measurable technical milestone rather than a completed network-wide capacity expansion. BNB Chain has demonstrated that eliminating redundant execution can materially increase throughput on BSC Testnet, but a mainnet deployment would be needed to establish its full operational impact.
