Gas Limit of a Block
The maximum total gas allowed for all transactions included in an Ethereum block.
What is Gas Limit of a Block?
The block gas limit on Ethereum caps the total gas that all transactions in a single block can consume, controlling the computational load on the network. As of 2025, Ethereum’s block gas limit is approximately 30 million gas, adjusted dynamically by validators under EIP-1559 rules to manage network congestion. This limit ensures blocks are processed efficiently within the 12-second slot time, balancing throughput and decentralization. Exceeding the block gas limit prevents a block from being valid, maintaining network stability.
