According to Decrypt, the Ethereum Sepolia test network activated the Glamsterdam upgrade on October 6. This activation set a block gas limit near 200 million for the test network. Mainnet currently uses a block gas limit of approximately 60 million. The increase on Sepolia represents more than three times the capacity of mainnet under normal conditions. The change was implemented as part of testing procedures on the Sepolia network. No details were provided regarding timing, technical rationale, deployment scope, or impact on user activity. The upgrade name “Glamsterdam” was mentioned in relation to the Sepolia test network activation. Mainnet’s 60 million figure reflects its current operational limit and is not altered by this test-network change.
