On Ethereum, the gas price is defined in terms of the Ether cryptocurrency, and the gas limit is based on how complex the sequence of operations is. For instance, transferring cryptocurrency from one address to another is a cheap operation, whereas deploying a new smart contract can be very expensive. Gas Performance Now that you know what Ethereum gas fees are, let’s take a look at how they work. Since Ethereum is still using the proof-of-work (PoW) concept, miners play a vital role. They provide the computational power, which is required to verify and process transactions. As such, there is a miner behind every transaction. Further, since it would be absurd to expect miners to do that work for nothing, they must be compensated. The latter is accomplished with Ethereum gas fees. As such, you can also look at network gas fees as a reward for miners. The exact gas price in gwei depends primarily on the network congestion. However, the amount of gas depends on how large of a contract you are trying to execute and how quickly you want it executed.
Gas costs also relate to the blockchain you use. Proof-of-work blockchains typically have higher gas fees since mining requires more computing power and electricity than staking. Often, when you hear someone talking about gas fees, they're referring to the Ethereum blockchain. This is because the Ethereum network has had extraordinarily high gas fees in the past. GAS to ETH Converter If you want to move Ether (ETH), Ethereum’s native cryptocurrency, between addresses, then you’re going to need to pay for gas. Or if you want to mint your own NFT or exchange ETH for other tokens, that too is going to cost you gas.
