Ethereum’s core developers are working toward a block gas target of 60 million before the Fusaka upgrade. While performance optimizations are showing progress, challenges such as state growth & client sync bottlenecks still need resolution. The initiative aims to ensure that Fusaka launches on a stronger, more scalable execution foundation.
The 60M Gas Target
Ethereum’s gas limit defines the maximum computational effort per block. Developers are now aiming to raise the target to 60M, a significant leap designed to unlock higher throughput for smart contracts & decentralized applications. Achieving this milestone before Fusaka ensures that scaling improvements align with broader ecosystem needs.
Bottlenecks & Performance Challenges
Several critical bottlenecks must be addressed before Ethereum can safely handle a higher gas load:
- State growth: expanding storage requirements risk overwhelming client databases.
- Sync performance: slower clients struggle to keep pace under heavy network activity.
- Validator stability: ensuring that resource-constrained nodes can remain fully operational.
Optimizations at the opcode level, such as improvements for mod and div, already demonstrate progress in reducing execution costs in high-gas environments.
Measurement Efforts & Client Readiness
Teams like Nethermind and PandaOps are leading measurement campaigns, producing shared dashboards that allow clients to compare performance in real time. These insights guide targeted fixes and highlight where engineering resources are most needed.
For the gas limit increase to proceed, all major clients must demonstrate mainnet-like stress test readiness, ensuring no single implementation becomes a bottleneck for network reliability.
Conclusion
The move toward a 60M gas target reflects Ethereum’s drive to improve scalability while maintaining decentralization & security. By carefully measuring performance, optimizing execution, and aligning client readiness, developers aim to strengthen Ethereum’s base layer ahead of Fusaka. The outcome will determine how confidently Ethereum can scale to meet growing global demand.
