Ethereum gas limit rises toward 45M as ETH price eyes $4000.

Ethereum’s base layer is undergoing a major performance shift, with the network’s gas limit rising toward 45 million units, a move that could meaningfully expand its transaction throughput.

According to a July 20 update on X from Ethereum co-founder Vitalik Buterin, nearly 50% of stake is currently showing support for the change, with the limit already climbing to 37.3 million. On Ethereum, “gas” is the unit of computational expense needed to process transactions or smart contracts.

In order to maintain fair pricing of network resources and reduce spam, users pay for gas in ETH. The amount of total computation that can be contained in a single block is then determined by the gas limit.

Each transaction has a gas limit, which is typically around 21,000 for a normal transfer. The block gas limit sets the upper bound for the entire block, controlling its size and processing load. Ethereum’s block gas limit has increased in tandem with network demand and advancements in technology in the past.$ETH
