Ethereum Prepares for Capacity Upgrade with Experimental Network

Key Summary

Ethereum's Sepolia testnet has activated the Glamsterdam upgrade, which includes a 200 million gas limit option, allowing validators to opt-in to the increased capacity. This upgrade bundles structural changes with raw capacity increases, aiming to expand Layer 1 capacity. The opt-in structure on Sepolia allows developers to observe validator behavior and node performance under heavier blocks before committing to mainnet.
