Ethereum enters the final testnet phase of the Fusaka upgrade, which will introduce a gas limit of approximately 16.78 million for each transaction.

Ethereum has entered the final testnet phase of its Fusaka upgrade, the final step before the mainnet launch, scheduled for December 3rd. This upgrade will introduce a gas limit of approximately 16.78 million per transaction, improving block efficiency, reducing denial of service (DoS) risks, and paving the way for parallel execution in future upgrades like the Glamsterdam upgrade. This mechanism, already activated on the Holesky and Sepolia testnets, prevents a single transaction from consuming an entire block's worth of gas. Previously, a single transaction could consume a block gas limit of up to approximately 45 million, potentially congesting the network and limiting scalability. The Fusaka upgrade (EIP-7825) also increases the Ethereum block gas limit to 60 million and introduces Peer Data Availability Sampling (PeerDAS), which allows nodes to store only a portion of Layer 2 data, reducing hardware requirements and enabling higher throughput. The next phase of the Fusaka upgrade will be deployed on the Hoodi testnet on October 28, with the mainnet deployment expected to be completed in December 2025. The subsequent Glamsterdam upgrade (EIP-7928) will focus on the execution layer. (Cointelegraph)
