What happened
Ethereum’s Sepolia test network activated Glamsterdam on October 6 with a block gas limit near 200 million, over three times mainnet’s 60 million.
Reported details
- The Sepolia rehearsal has raised its processing budget more than threefold, but sampled blocks used less than half that allowance.
Why this matters
This reads as a change in infrastructure rather than a move in price, and that distinction decides what is worth verifying: whether the underlying record moved, or only the interface around it. If a ledger, custodian or settlement term is unchanged, then anything built on top of it behaves the same too, however the announcement is framed. Subject of the report: Ethereum Test Network.
Evidence boundary
The scope is limited to what the linked reports state, and where two of them diverge both positions are recorded without either being picked in advance.
What to verify
If Ethereum Test Network points at a contract or a chain, verify the deployed address and version there. If it describes an internal or corporate change with no on-chain component, the chain is the wrong place to look.
