Ethereum Schedules Hoodi Upgrade Testnet for October 26 as Core Developers Target 200 Million Gas Limit

Ethereum’s technical roadmap is accelerating into late October as core protocol developers finalize preparations for a crucial scaling stress test.

The network has officially set October 26, 2026, for the launch of the Hoodi testnet upgrade, designed to evaluate validator performance and node stability under an unprecedented 200 million gas limit per block.

The upcoming Hoodi deployment represents a major milestone in testing execution capacity beyond current mainnet parameters.

Scaling Gas Limits

The test will drastically increase execution throughput on the testnet to observe how validator nodes handle elevated state growth, memory usage, and transaction processing bandwidth.

Client teams have issued mandatory software updates across execution and consensus clients ahead of the October 26 fork, ensuring client diversity and network synchronization remain robust under high-load conditions.

Insights gathered from Hoodi’s 200 million gas environment will directly inform optimization parameters for the upcoming Glamsterdam upgrade, which is undergoing parallel testnet evaluations.

Infrastructure Race

The announcement comes as Ethereum navigates a period of consolidation, trading around $2,420 following broader macroeconomic headwinds and hot U.S. wholesale inflation data that weighed on risk assets.

Despite short-term price chop, protocol developers are maintaining a steady focus on layer-1 optimization. As competing layer-1 blockchains push sub-second latency targets, Ethereum’s systematic approach to raising execution capacity while safeguarding node decentralization underscores its long-term strategy for high-volume enterprise and DeFi adoption.
