What is Gas War?
A gas war is a period of intense competition where users rapidly increase transaction fees to ensure their transactions are included in the next block. This typically happens during high-demand events like popular NFT mints or token launches.
How does Gas War work?
- A high-demand event creates a surge in transaction volume.
- Users bid higher gas prices to out-compete others.
- Bots and automated tools continuously adjust fees upward.
- Validators prioritize the highest-paying transactions.
- Network-wide gas prices spike until the demand event ends.
Why does Gas War matter?
Gas wars reveal the scarcity of block space and the limitations of network scalability. They can price out average users, making the network temporarily unusable for anything other than the high-stakes event.
Key features of Gas War
- Sudden, extreme fee spikes
- Driven by limited block space
- Favors users with more capital
- Common during NFT "mints"
- Results in many failed or expensive transactions
Examples of Gas War
A "blue-chip" NFT drop often triggers a gas war, where users might pay thousands of dollars in fees just to ensure they can mint an item before it sells out.
