BSC Moves Toward a 70 Million Gas Target
BNB Smart Chain is entering another stage of its scaling roadmap as validators move toward a 70 million target block gas limit.
The rollout began on September 14, with the remaining validator upgrades expected to be completed by September 15. BNB Chain developers said network traffic remains above 95%, while BSC continues to operate stably.
The higher target is designed to give BSC more room to process transactions as demand continues growing across DeFi, payments, tokenized assets and other onchain applications.
Importantly, the 70 million figure is a target rather than a permanently hard-coded limit. Validators are instructed to derive the effective value from the parent block and adjust their block-packing and simulation strategies for larger blocks.
Pasteur Created the Foundation for Higher Capacity
The latest capacity expansion follows the Pasteur hard fork, which activated on BSC mainnet on August 25, 2026.
One of the key components of Pasteur was BEP-675, which changes how blocks are prepared and submitted by allowing builders to submit fully executed blocks.
Under the previous process, builders executed transactions and then validators performed redundant execution before sealing the block. BEP-675 moves more of that work to specialized builders, reducing the execution burden on the validator's critical path.
The result is more time for builders to pack transactions into each block.
BidBlock V2 Is Already Packing More Gas
The new architecture is being used through BidBlock V2, and early mainnet data indicates that it has materially increased the amount of gas processed per block.
BNB Chain developers report that BidBlock V2 has become the dominant block-building path following Pasteur, with average gas per block approximately 28% higher than BidBlock V1. Peak blocks have reached around 43.8 million gas, while BidBlock V2 has handled roughly 98% of recent BSC blocks.
This is important because BSC is not simply increasing its gas ceiling without improving the infrastructure underneath it.
The network first improved block construction efficiency and is now using that additional efficiency to create more capacity.
Testnet Results Show the Potential of BEP-675
The architecture has also produced strong results in controlled testing.
On BNB Chain's QANet testnet, BEP-675 increased throughput from 1,237 TPS to 2,324 TPS, an 88% improvement, while keeping the block interval at 450 milliseconds and the gas limit at 100 million.
Average gas used per block increased from 46.35 million to 84.15 million, while finality lag remained unchanged in the benchmark.
These are testnet results under a controlled workload, rather than a direct measure of current mainnet throughput. However, they demonstrate why BNB Chain sees the architecture as an important part of its scaling strategy.
Why BSC Needs More Capacity
The move toward 70 million gas comes as BSC utilization remains above 95%.
When a network consistently operates close to its available block capacity, there is less room to absorb sudden increases in transaction activity.
Increasing the gas target allows more computational work to be included in individual blocks, potentially providing additional headroom during periods of high demand.
For BSC, that capacity is becoming increasingly important as activity expands across:
Higher capacity does not automatically mean lower fees or faster transactions, however. Those outcomes still depend on actual demand, block efficiency and network conditions.
BSC's Scaling Roadmap Extends Beyond 70M
The 70 million target is only the next stage of BSC's broader scaling roadmap.
BNB Chain developers have indicated a progression toward 80 million and potentially 90 million gas per block, depending on mainnet performance and infrastructure readiness.
The staged approach allows validators and developers to monitor how the network responds before moving to the next capacity level.
Key factors include block propagation, validator performance, node synchronization, finality, missed blocks and the ability of builders to efficiently construct larger blocks.
This makes each gas-limit increase both a scaling step and a test of BSC's infrastructure.
Larger Blocks Also Create New Technical Challenges
Higher gas limits bring additional requirements for validators and node operators.
Larger blocks require more computation and can take longer to process, propagate and synchronize across geographically distributed infrastructure.
If certain validators or nodes struggle to keep up, increasing block sizes could raise infrastructure costs and potentially increase pressure toward greater hardware requirements.
That is why BNB Chain's approach is incremental rather than immediately moving to its longer-term capacity targets.
The network can evaluate real-world performance at each stage before deciding whether additional increases are appropriate.
What the 70M Target Means for BNB Chain
The latest gas-limit adjustment is part of a broader effort to make BSC capable of supporting a larger onchain economy.
BNB Chain has been expanding activity across tokenized assets, stablecoins, DeFi and other financial applications, increasing the importance of reliable transaction capacity.
The network's recent infrastructure upgrades therefore have two complementary goals: process more transactions and make block production more efficient.
Pasteur and BEP-675 address the second part, while the move toward 70 million gas addresses the first.
Together, they give BSC additional headroom as demand continues to grow.
BSC Positions for the Next Scaling Phase
The 70 million target could become an important checkpoint for BNB Smart Chain's infrastructure roadmap.
If the network continues operating reliably at higher gas levels, BSC could move toward its planned 80 million and potentially 90 million targets.
However, capacity increases will ultimately need to be balanced against network stability.
For validators, the challenge is not simply processing more transactions. They must also maintain fast propagation, reliable finality and consistent synchronization as block sizes increase.
Conclusion
BNB Smart Chain is moving toward a 70 million target block gas limit as network traffic remains above 95% and demand continues to rise.
The expansion follows the Pasteur hard fork and BEP-675, which changed BSC's block-building architecture and enabled BidBlock V2 to pack more gas into blocks. Mainnet data shows approximately 28% more gas per block, while controlled QANet testing demonstrated an 88% throughput increase under the new architecture.
With 80 million and potentially 90 million gas identified as future scaling stages, BNB Chain is taking a gradual approach to increasing capacity.
If BSC can maintain stability as blocks grow, the latest expansion could give the network more room to support the next wave of DeFi, payments, tokenized assets and onchain applications.
