Ethereum's Sepolia testnet forks to Gloas with 200M gas limit

Gloas: Gloas is the consensus-layer upgrade component within Ethereum's Glamsterdam network upgrade, paired with the Amsterdam execution-layer changes. It introduces features such as enshrined proposer-builder separation (ePBS) and related builder support mechanisms to reshape block production and validation. The Sepolia activation at the specified epoch and time tests these consensus-layer modifications ahead of potential mainnet deployment. Ethereum: Ethereum is the leading decentralized blockchain platform that supports smart contracts, decentralized applications, and a wide ecosystem of layer-2 scaling solutions. It operates under a proof-of-stake consensus mechanism following The Merge and continues iterative upgrades to improve scalability, security, and efficiency. The Sepolia testnet fork to Gloas represents a key step in testing the consensus-layer changes of the broader Glamsterdam upgrade on Ethereum's infrastructure. Testnet Focus: Sepolia serves as the initial testbed for Glamsterdam activation, with subsequent testing planned for other networks like Hoodi before any mainnet consideration. Upgrade Scope: Glamsterdam bundles the Gloas consensus-layer upgrade with Amsterdam execution-layer changes, focusing on block production efficiency and state handling. Client Preparation: Multiple Ethereum consensus and execution clients released updates to support the Gloas fork on Sepolia, including configuration for builder-related features.
