One of the most anticipated changes to Ethereum, EIP-1559 is the largest change that will be introduced in London. The EIP will introduce a “base fee” in blocks on the network which will track the gas price that the network will accept from transactions based on demand for blockspace. This means that it will be easier for wallets and users to estimate what the right price for their transaction should be.
Additionally, EIP-1559 adds a new transaction type where users can specify the maximum fee they are willing to pay, along with the maximum they are willing to send to the miner, and get a refund for the difference between that maximum and the base fee and miner tip. Finally, the EIP will also cause part of the transaction fees to be burnt, which is something that a large part of the community see as a critical improvement to the Ethereum network’s economics.
