They are a unit of measurement of ETH that expresses transaction fees and their associated costs within this network. As such, we can conceptualize them as a fraction of the ETH cryptocurrency.
Quantitatively, one Gwei is equivalent to 0.000000001 ETH.
Transaction fees on Ethereum are calculated in Gwei, whose cost per operation is determined by multiplying the Gwei to be paid by the "gas" (refers to the computational effort necessary to execute the transactions) relative to that same transaction.
In this sense, Gwei are essential measures for the setting and payment of fees derived from operations in this network, which, being a much smaller unit of measurement than Ether, allows great flexibility in setting fees on transactions.
What is the function of these rates?
Gas rates should be understood as incentives for validators to participate in the validation process inherent to the network.
In addition, they contribute to the mitigation of spam on the network. By assigning a certain cost to each transaction, malicious entities and individuals are deterred from overloading the network with unnecessary transactions.
In short, the above means that users can stipulate rates in terms of network conditions and the urgency for carrying out each operation. Likewise, the use of Gwei avoids rounding errors and provides transparency to transaction costs.
