What Is the Purpose of Burning the Base Fee under EIP-1559?

The primary purpose of burning the base fee is to make the supply of the native cryptocurrency, Ether (ETH), deflationary or less inflationary. This mechanism offsets the issuance of new ETH to validators, creating a scarcity effect that can theoretically increase the asset's value.

It also acts as a natural control on network usage, as the burned fee represents a cost that cannot be immediately recovered.
