While looking back on August’s London hard fork, it is easy to focus on the millions of ether burnt via transaction fees. While important, just looking at the burn mechanism would be shortsighted and overly focused on “number go up.”

So what was the motivation for EIP 1559 and, after four months, what real impacts have we seen? Below are four of the core issues that the improvement proposal aimed to address:

A report from Coinbase highlights the upgrade’s effects seen during operation, in which the exchange noted it is currently saving 27 ETH per day from base-fee refunds. When contrasting legacy style transactions with post-EIP 1559 style transactions, Coinbase saves 9% per transaction using the new format.

Another noticeable improvement post-EIP 1559 was the broadcast-to-confirmation time that Coinbase recorded on transactions. While saving on gas, Coinbase also saw transactions confirmed an average of 11 seconds faster than before the London hard fork. Blocktime on Ethereum typically takes 13 seconds, so the upgrade speeds confirmation up by 0.7 blocks.

On the opposing side, Galaxy Digital’s look into EIP 1559 reported issues due to increased block size (gas limits) and the gaming of an algorithmically adjusting base fee. While Ethereum developers increased the gas limit with the hope that blocks would find an equilibrium around 15 million gas, the reality has been a majority of completely full blocks nearing 30 million gas. Higher gas limits and full blocks strains mining and node hardware and can have negative impacts on the decentralization of a network.

Finally, tech savvy users and bots have been able to look at the mempool, where all pending Ethereum transactions are waiting to process, and see whether the base fee will adjust up or down in the next block. With this information, bots are able to send transactions within the cheaper block and essentially game the algorithm.

The burn mechanism built into EIP 1559 helps solve a long-term validation problem inherent to blockchains. Block rewards into perpetuity help incentivize miners and validators to bring security to the network, but the associated inflation is detrimental to the network’s native token. In order to solve this dilemma, EIP 1559 burns transaction fees to counteract block reward inflation.
