Ethereum has raised its block gas limit to 60 million as it prepares for the Fusaka upgrade. This change is attributed to improvements in block-size safeguards, client optimizations, and successful testnet results. The upgrade is set to enhance network efficiency and transaction throughput.

Ethereum researcher Dankrad Feist has proposed a gradual increase of the gas limit from 36 million to 3.6 billion over four years through EIP-9698. If adopted, this could enable the Ethereum mainnet to process up to 2,000 transactions per second and improve scalability while addressing potential challenges for node operators.
