Gas limit refers to the maximum amount of computational work that can be included in a single transaction on a blockchain network, particularly those like Ethereum. Every operation executed on the network requires a certain amount of gas, which serves as a way to measure the computational effort involved.When a user initiates a transaction, they specify a gas limit to indicate how much work they’re willing to pay for. If the transaction’s required gas exceeds this limit, it will fail, but the user will still lose the gas fees spent up to that point.Setting the gas limit too low may result in a failed transaction, while setting it too high can lead to unnecessary costs. Therefore, users often adjust their gas limit based on current network conditions, which can fluctuate due to demand and congestion.Overall, the gas limit plays a crucial role in managing network resources, ensuring that transactions can be processed efficiently while preventing abuse or spam on the network.
