 Ether burn occurs in every transaction on Ethereum. When users pay for their transactions, a base gas fee, set by the network according to transactional demand, gets destroyed. This, coupled with variable block sizes and a maximum gas fee, simplifies transaction fee estimation on Ethereum. When network demand is high, [blocks](https://etherscan.io/block/12965263) can burn more ether than they mint, effectively offsetting ether issuance.
 
-Burning the base fee hinders a block producers ability to manipulate transactions. For example, if block producers received the base fee, they could include their own transactions for free and raise the base fee for everyone else. Alternatively, they could refund the base fee to some users off-chain, leading to a more opaque and complex transaction fee market.
