Simple definition
Gas fees are small charges you pay to have a transaction processed on some blockchains, like Ethereum. Think of them as a processing fee.
How it works
- Every action on the blockchain needs computers to do work.
- You pay a fee to reward those computers.
- The fee rises when many people are using the network and falls when it is quiet.
Everyday example
In real life
It is like a toll road. The toll is higher at rush hour. Sending a small amount at a busy time can cost more in fees than the amount itself.
