Gas

Gas is a fee required to conduct transactions or execute smart contracts on blockchain networks like Ethereum. It compensates validators for the computational resources needed to process and validate actions. Gas prices fluctuate based on network demand, affecting transaction speed and cost. Users can set their gas price; higher fees often mean faster processing. Understanding gas is crucial for managing transaction costs effectively and ensuring successful interactions on the blockchain. It is a fundamental concept that helps maintain network security and efficiency by incentivizing resource allocation.
