Gas fees in the cryptocurrency world, particularly in networks like Ethereum, are transaction costs required to execute and validate smart contracts or transactions. They exist because blockchain networks need to compensate nodes for the computational work and electricity used in processing these transactions. Essentially, gas fees ensure the network's sustainability and prevent spam by pricing out unnecessary or malicious transactions. These fees vary based on network congestion and the complexity of the transaction, incentivizing users to optimize their transactions for efficiency.
