Ethereum’s network has witnessed a noteworthy enhancement with the gas limit being raised to 45 million units, up from the previous 36 million, marking a 25% increase. This update was implemented in block number 22,968,004, with nearly half of the network validators approving the rise. The gas limit determines the computational power allowed per block, thus directly impacting transaction capacity. This increment enables more data to be processed in a single block, leading to improved scalability of the Ethereum 
$2,316 network.
Significant Gas Limit Increase on Ethereum
Changes in the gas limit within Ethereum do not necessitate a hard fork. Instead, validators propose a block to adjust their node configurations. Once the support signal surpasses 50%, the gas limit automatically shifts to the new level.
Prior to this latest adjustment, the gas limit was 30 million, having doubled from 15 million in 2021 and subsequently increased to 36 million in February. Future targets of 60 million in the short term and 150 million in the long term are already being discussed. These advancements are anticipated to be feasible with the Fusaka hard fork (EIP-7935).
The increase in the gas limit is driven by a growing expectation within the community for enhanced scaling. A larger block capacity boosts simultaneous transactions and smart contract executions. Consequently, during periods of high transaction volume, waiting times decrease, and fee pressure alleviates. However, the motivation behind this decision is not solely transaction speed but also an adaptation to the network’s increasing usage.
Technical Safeguards to Mitigate Risks
Developers have introduced protective measures to ensure the network’s security isn’t compromised by the higher gas limit. EIP-7983 acts as a buffer against denial-of-service (DoS) attacks by limiting the gas a single transaction can use to 16.77 million units. This ensures that while the total gas per block increases, individual transactions do not overwhelm the system.
The ambitious targets of 60 and 150 million set by validators indicate that the current increase is just a stepping stone. Nevertheless, the process heavily relies on the consensus of the majority of signaling validators. Each increment in the gas limit must carefully balance the network’s enhanced capacity with its stability.
