BNB Chain reported that its Binance Smart Chain (BSC) network has achieved a benchmark throughput of approximately 5,200 transactions per second (TPS) by June 2026, almost doubling its TPS from 2,800 at the beginning of the year. BNB Chain is a leading blockchain platform recognized for prioritizing scalability and speed across its ecosystem.
The network reduced its block interval from 750 milliseconds to 450 milliseconds in the first half of 2026, decreasing the time users wait for new blocks to be added and resulting in faster transaction confirmations for developers and applications. BNB Chain also reported that its memory finality improved from 1,125 milliseconds to 650 milliseconds, further reducing the time required to consider transactions as finalized.
BNB Chain highlighted a significant year-to-date rise: “Block intervals: 750 ms to 450 ms, memory finality: 1,125 ms to 650 ms, benchmark throughput: 2,800 to 5,200 TPS. H2 goes further, targeting another 2x throughput increase.”
In parallel, network throughput reached the 5,200 TPS milestone, allowing the BSC to process far more transactions per second than at the start of 2026. This growth serves BNB Chain’s growing user and developer base, which requires higher performance for both decentralized applications and token transfers.
Mini dictionary: Block interval refers to the time between the creation of two consecutive blocks in a blockchain, impacting how quickly new transactions can be processed. Memory finality is the time it takes for a transaction to be confirmed as irreversible on the network.

Key enhancements included the Block-Level Access List (BAL), which enables transaction data to be prepared before execution, increasing efficiency and laying the groundwork for parallel processing in future updates.
Another key upgrade, Incremental Snapshot, allows new or delayed nodes—computers responsible for helping operate the blockchain—to synchronize more quickly with the active chain. Enhancements to the Ethereum Virtual Machine (EVM), known as EVM SuperInstruction, seek to reduce unnecessary repeat executions, boosting overall throughput. The introduction of Extended Voting Rules is designed to maintain transaction finality even under challenging network conditions.
Mini dictionary: BSC, or Binance Smart Chain, is a blockchain network built for running smart contract-based applications with high throughput and lower transaction fees, operating alongside Binance Chain.
For the second half of 2026, BNB Chain is targeting another twofold increase in throughput on BSC’s mainnet, forming part of a broader multi-year strategy to achieve a tenfold performance boost. The roadmap outlines plans to implement BEP-675 upgrades and additional fine-tuning of the BAL to further raise network capacity.
Additional roadmap goals include more robust congestion control measures to ensure stable network performance during periods of high demand. The decision to introduce dedicated lanes aims to limit interference between different applications operating on the blockchain.
BNB Chain is also preparing new gas fee models designed for specific business segments, aiming to optimize transaction cost structures for various user groups. The team is developing a new Layer 1 chain architecture with the ambition of reaching over 100,000 TPS and achieving sub-50 millisecond transaction preconfirmation times.
Mini dictionary: BEP-675 is a proposed protocol enhancement for the BSC, aiming to optimize transaction execution and throughput by enabling improved parallel processing and resource management.
