Crypto Economy says the Glamsterdam testnet launched Aug. 13, while NFTevening and BlockchainReporter both cite an Aug. 17 announcement.

What all sources agree on

• The Glamsterdam fork is scheduled to activate on the Platåberget testnet on Aug. 20.
• Glamsterdam introduces a separate state-gas dimension for operations that create new state, such as account creation or new storage.
• A standard ETH transfer to an existing account will still cost 21,000 gas, but sending to a new account will involve an additional state-gas charge.
• Wallets, indexers and gas estimators that rely on a fixed or hardcoded maximum gas limit will need to be updated or will stop working correctly.
• The upgrade also includes enshrined proposer-builder separation, block-level access lists and expanded limits for contract code size.

Where the reports disagree

1Date the Platåberget testnet launched or was announced

The Ethereum Foundation urged developers to test their systems on Plataberget, a public testnet launched on August 13 and designed to run for several months.

On August 17, the Ethereum Foundation announced Platåberget, a public testnet for the Glamsterdam upgrade, where wallet, dApp, and Ethereum infrastructure development teams can test changes early before they are deployed to Sepolia, Hoodi, and eventually mainnet.

In its Aug. 17 announcement, the Ethereum Foundation said the network is intended to run for several months before Glamsterdam moves to longer-lived testnets.

What would settle it: The Ethereum Foundation's original Platåberget announcement post or its published timestamp/changelog.

What to make of it

Treat the Aug. 20 Glamsterdam fork date and the gas-model/state-gas changes as established across all three reports; the exact date Platåberget itself launched or was announced (Aug. 13 vs. Aug. 17) remains unresolved until the Foundation's own announcement timestamp is checked.
