Gas is a metric utilized to calculate the expenses or charges involved in performing transactions or running smart contracts on the network. Every operation, such as sending tokens or executing code, requires a specific amount of gas that depends on the complexity of the operation. Usually, gas fees are paid in the native blockchain network digital asset, such as Ether (ETH) for Ethereum, for example. Those fees are incentives for network participants, such as miners or validators, to process and verify transactions. Gas fees play a vital role in maintaining the security and efficiency of the network by preventing spam, prioritizing transactions, and compensating miners or validators for their computational work.
