In order to incentivize miners to process transactions and verify blocks, Ethereum introduces the concepts of Gas and Gas fees. Gas is a unit used to measure the cost of Ethereum transactions, representing the cost required for the transaction. The Gas fee is the payment required for executing Ethereum transactions, which is calculated based on the consumption of Gas."}]}],"pr":"b910d3abd31229b526d50eb7742a09496147d5b56676fdcb2839bc04f9c1ceec"}
