Ethereum quietly crossed a major milestone this week. The network’s mainnet Gas Limit has been officially raised to 60 million, a full 2× increase from where it stood at the start of the year.
For nearly four years, Ethereum maintained a cautious ceiling around 30 million, holding the limit steady while prioritizing stability over throughput.
The sudden acceleration marks a decisive shift. Developers are no longer treating L1 scaling as something that must move at a glacial pace. Instead, 2024 has ushered in a new mindset: scaling through empirical science instead of conservative restraint.
昨天，以太坊主网的 Gas Limit 正式提升至 60M，相较年初已实现翻倍。而过去近四年间，这个数字一直被谨慎地维持在 30M 左右。
是什么原因让以太坊开发者在今年突然决定如此激进地推动 L1 扩容？我认为，这背后的关键在于一场从谨慎保守到「实证科学」驱动的扩容范式转移。

A Gas Limit That Stayed Frozen for Years Finally Moves
Ethereum’s Gas Limit has always been a sensitive parameter. Raising it increases the computation packed into each block. Bigger blocks stress hardware, widen propagation times, and push node storage toward dangerous levels.
These risks kept the limit anchored around 30M since 2020. Changes occurred, but always in small, hesitant increments.
That posture has now changed. With the push to 60M, Ethereum signals that its L1 is ready for more activity, not because the risks disappeared, but because the technology and data finally support the expansion.
Why Raise the Limit Now? A Paradigm Shift Inside Ethereum
The core driver behind this year’s aggressive scaling move is a change in philosophy. Ethereum’s ecosystem is now guided by empirical evidence, testnet stress simulations, and measurable performance benchmarks, not worst-case assumptions.
This new posture didn’t emerge overnight. It came from several structural upgrades across the protocol and the client layer.
EIP-7623: The Turning Point That Created Room for Growth
The most important catalyst appeared in 2024 with EIP-7623, a proposal that tightened Ethereum’s worst-case block size. Developers raised the Gas cost of calldata, the section of a transaction that can inflate block size unpredictably.
Before EIP-7623, a malicious or unusually calldata-heavy block could balloon far beyond the typical size. That forced the Gas Limit to remain low out of caution.
After EIP-7623:
- Maximum block sizes became more predictable
- Extreme calldata bloat was eliminated
- A safety buffer was created for future Gas Limit increases
This change allowed developers to revisit the 30M limit with renewed confidence. They no longer had to guard against extreme block volatility.
Client Performance Skyrockets After Major Optimization Wave
While protocol-level changes created the theoretical space for bigger blocks, the real breakthrough came from the client teams.
Ethereum’s major implementations, Nethermind, Erigon, Reth, and others, spent the last year aggressively optimizing core execution pathways.
Developers benchmarked clients and discovered bottlenecks in key cryptographic and computational operations, especially in ModExp precompiles. These bottlenecks historically slowed verification speeds during high Gas usage.
Using proposals like EIP-7883, teams:
- Repriced expensive operations
- Refactored slow-dominated code paths
- Optimized algorithms at the VM level
The result:
Client execution speeds improved enough to handle 60M Gas blocks without strain.
The difference is measurable. Profiling shows that the latest client versions complete block verification well within Ethereum’s consensus constraints. What was once a limitation has now become a non-issue.
Stress Tests Confirm Ethereum Can Handle 60M Safely
The protocol upgrades and performance improvements didn’t stay theoretical. Developers deployed them across major testnets, Sepolia and Hoodi, and ran high-load simulations.
The findings were clear:
- Nodes validated 60M Gas blocks within the required 4-second consensus window
- Block propagation delays remained within safe bounds
- No test network showed issues with chain stability
- Majority of nodes sustained verification performance without stalling
These results gave developers the final confirmation they needed. The network wasn’t just theoretically ready, it was practically ready.
Ethereum Eyes 100M Gas Limit Next, But With Caveats
The new 60M limit is not the final destination. Developers openly discuss the possibility of pushing toward 100M Gas in the future. The motivation is straightforward: a higher Gas Limit increases L1 throughput at a time when decentralized applications continue to grow.
But reaching 100M isn’t a simple flip of a switch.
Three major challenges remain:
1. Heavy Cryptographic Operations Still Need Improvement
Tasks like elliptic curve computations continue to dominate execution time during peak loads. Further optimizations, or new precompiles, will be required.
2. State Bloat Must Be Controlled
As the chain grows, node hardware demands rise. State pruning, verkle trees, and improved storage strategies will be critical.
3. Propagation Speeds Must Stay Ahead of Block Size
If block sizes grow too quickly without corresponding improvements in networking, block propagation delays could weaken consensus.
Developers emphasize that the path to 100M will be gradual and backed by measurable data, not risky assumption-driven changes.
A Coordinated Push Across the Entire Ethereum Stack
The transition from 30M to 60M wasn’t driven by a single upgrade. It was the outcome of synchronized progress across:
- Protocol rules (EIP-7623)
- Client execution engines (Nethermind, Erigon, Reth)
- Algorithmic adjustments (EIP-7883)
- Stress testing (Sepolia, Hoodi)
- Data-driven confidence in production readiness
This multi-layer effort represents a structural evolution in how Ethereum approaches L1 scaling, not merely a one-time technical update.
The Gas Limit increase marks a symbolic shift in Ethereum’s culture. The network is no longer scaling cautiously by default. It is scaling through proof, measurement, and real performance data.
This doesn’t replace Ethereum’s long-term push toward rollups and modular scaling. But it reinforces the idea that L1 itself can still expand, provided that the expansion is backed by science, not optimism.
With the 60M limit now live, Ethereum enters a new phase. One defined not by holding the line, but by pushing it, carefully, methodically, and with evidence.
