Gas: The term “gas” within the blockchain context, particularly on Ethereum, signifies the unit of measure that quantifies the computational effort required to execute operations such as transactions or smart contract executions on the network. This system ensures that every action taken on the blockchain, from simple transactions to complex smart contract interactions, incurs a fee, payable in Ether (ETH), Ethereum’s native cryptocurrency. The cost of gas is determined by the supply and demand dynamics of the network’s computational power, leading to variable transaction fees. Gas fees are crucial for compensating miners or validators for their efforts in processing transactions and securing the network, as well as for preventing spam by making all operations costly enough to deter frivolous or malicious activity.

A key element in the Ethereum ecosystem, gas fees balance the need for network security with the usability and efficiency of executing transactions and smart contracts.
