BNB Chain Tests 88% TPS Boost With BEP-675 Upgrade Ahead of Pasteur Hard Fork

Author: CoinTrust·

Key Takeaways

  • BEP-675 increased BSC testnet throughput by 88% to 2,324 transactions per second without changing the gas limit or block interval.
  • The upgrade allows block builders to submit fully executed blocks, cutting validator execution time from roughly 125 milliseconds to 15 milliseconds.
  • The BSC mainnet Pasteur hard fork scheduled for August 25 is slated to include BEP-675 alongside Block-Level Access Lists.
  • BNB Chain obtained ISO/IEC 27001 and 27701 certifications from the British Standards Institution covering security and privacy management at the infrastructure level.
  • Average gas consumption per block rose from 46.35 million to 84.15 million during testing while execution performance and finality latency remained stable.
BNB Chain Tests 88% TPS Boost With BEP-675 Upgrade Ahead of Pasteur Hard Fork

BNB Chain has reported strong performance results from BEP-675, a proposed upgrade currently being tested on the Binance Smart Chain (BSC) testnet as part of its second-half 2026 scaling roadmap. The proposal increased transaction throughput by 88% during testing, reaching 2,324 transactions per second (TPS) compared with a baseline of 1,237 TPS.

The improvement was achieved without increasing the network's 100 million gas limit or altering its 450-millisecond block interval. The results suggest that BNB Chain can extract additional capacity from its existing block-production framework by eliminating redundant transaction processing—a source of overhead that affects EVM-based networks where validators traditionally re-execute transactions that builders have already processed.

Eliminating Duplicate Block Execution

Under the current process, block builders execute transactions before submitting their bids to validators. Validators then execute those same transactions again before finalizing the block. BEP-675 changes this workflow by allowing builders to submit blocks that have already been fully executed.

According to the test results, this modification reduced validator execution time from approximately 125 milliseconds to 15 milliseconds. The freed-up time gives builders more room to fill blocks closer to their available gas capacity, improving resource utilization without directly changing finality conditions.

The test was conducted on QANet, a cross-region testnet designed to approximate mainnet operating conditions. Average gas consumption per block increased to 84.15 million from 46.35 million, while median usage rose from 29.49 million to 98.99 million. Despite the higher block utilization, the test reportedly maintained stable execution performance and finality latency.

The change also addresses a previous limitation in which as many as 25% of blocks could be submitted partially filled because builders lacked sufficient time to maximize available block capacity. By reducing the duplicated execution workload, BEP-675 grants block builders additional processing time to use available gas more efficiently, potentially increasing BSC throughput without requiring a larger gas limit.

Mainnet Testing Remains the Next Challenge

BNB Chain has indicated that the testnet results still require validation under mainnet conditions. One critical test will involve scenarios where several competing bids are submitted during the same block slot, which could place additional pressure on the revised execution model.

BEP-675 forms part of BNB Chain's broader 2026 strategy to improve capacity for high-volume applications, including decentralized finance (DeFi), gaming, and payment services. The network had already reduced its block interval to 450 milliseconds following the January 2026 Fermi hard fork and has pursued additional improvements aimed at substantially increasing throughput.

The BSC Mainnet Pasteur hard fork, scheduled for August 25, is expected to include BEP-675 alongside other changes, including Block-Level Access Lists. Builders adopting the new proposal will need to operate full nodes rather than fast nodes. Existing bid formats will continue to function, although legacy bids could face reduced block-packing time.

BNB Chain Adds Institutional Security Certifications

Alongside its technical scaling efforts, BNB Chain has received ISO/IEC 27001 and ISO/IEC 27701 certifications from the British Standards Institution (BSI). The certifications, announced on August 7, are intended to strengthen the network's credentials among banks, asset managers, governments, and other institutions evaluating blockchain infrastructure. Such independently verified certifications are commonly required in enterprise procurement processes before organizations adopt third-party technology platforms.

ISO/IEC 27001 focuses on information security management, including risk identification, access controls, and incident management. ISO/IEC 27701 extends privacy management requirements to the handling of personally identifiable information (PII), covering areas such as collection, processing, and storage.

BSI's assessment covered BNB Chain infrastructure and operational processes, including systems used for smart-contract deployment and execution, key management, and blockchain services. Under ISO/IEC 27701, BNB Chain was certified as a personally identifiable information controller, placing responsibility on the network organization for decisions concerning personal-data handling.

The certifications apply at the blockchain infrastructure level, giving institutional users third-party validation of BNB Chain's security and privacy management rather than limiting compliance assurances to individual applications or service providers.

Scaling and Compliance Move in Parallel

The certifications arrive as BNB Chain continues to pursue higher network performance. The network reported benchmark results of up to 5,200 TPS during the first half of 2026 while maintaining a 450-millisecond block interval.

With the Pasteur hard fork approaching, the combination of throughput improvements and infrastructure-level security certification reflects a dual strategy focused on performance and institutional readiness. Further mainnet testing of BEP-675 will determine whether the gains observed on QANet can be sustained under real-world conditions. If the upgrade performs as expected, BNB Chain could strengthen its position among networks seeking to support high-volume DeFi, tokenized assets, payments, and other Web3 applications while maintaining operational stability and institutional-grade security controls.
