💡 What is a Gas Fee?

A gas fee is a small payment you make when you perform an action on a blockchain — like sending crypto, minting an NFT, or interacting with a smart contract.

It’s called “gas” because, just like fuel powers a car, these fees “fuel” the network — they pay the computers (called nodes or miners/validators) that process and verify your transaction.

⚙️ Why Do Transactions Cost Money?

Here’s why fees exist:

Network Security 🔒

Blockchains are decentralized — no central authority runs them.

Instead, miners or validators use computing power to confirm transactions and secure the network.

Gas fees reward them for doing this work honestly.

Prevent Spam 🚫

If transactions were free, someone could flood the network with fake transactions.

Requiring a fee makes spamming expensive and keeps the system efficient.

Prioritization ⏩

When the network is busy, users who pay higher gas fees get their transactions processed faster.

It’s a supply-and-demand system.
