Ethereum Glamsterdam Upgrade Targets 200M Gas Limit in Devnet Testing
Ethereum developers are advancing the Glamsterdam upgrade through devnet testing, with core features including encrypted PBS and block-level access lists designed to support a 200 million gas limit per block. A public testnet deployment is proposed for October 6.

Devnet Progress on Core Features
Ethereum core developers have progressed the Glamsterdam upgrade roadmap through devnet work, with two technical pillars emerging as central to enabling a higher gas limit. Encrypted proposer-builder separation (ePBS) and block-level access lists are the primary mechanisms being tested to allow the network to safely process more computation per block without compromising security or validator hardware requirements.
The devnet has successfully raised the per-block gas limit target toward 200 million, roughly double the current 30 million limit, according to testing results. This represents a material step in the upgrade's feasibility phase — moving from theoretical design to hands-on validation across a live test network.
Timeline and Next Steps
Developers have scheduled a proposed public testnet deployment for October 6, pending continued stability on devnet. The upgrade would represent one of Ethereum's largest single increases to throughput since the Shanghai upgrade in April 2023, which introduced EIP-4844 (proto-danksharding) blob space.
The 200 million gas target remains a roadmap goal rather than a final specification. Developers will continue monitoring devnet performance, validator resource consumption, and block propagation times before committing to a mainnet deployment window.
Why It Matters
For Traders
A successful 200M gas upgrade would increase Ethereum's baseline capacity, potentially reducing base fee volatility and transaction costs under congestion over a 6-12 month horizon.
For Investors
A 6-7x increase in per-block throughput, if achieved, would materially improve Ethereum's competitive positioning against L2s and rival chains for high-frequency applications.
For Builders
Applications currently deployed on L2s may have economic incentive to settle on L1 if gas costs fall substantially; contract interaction patterns and fee markets will shift accordingly.
