While Ethereum (ETH) co-founder Vitalik Buterin explains how the long awaited network upgrade affected the chain capacity, the crypto community continues raising the high gas fees question.

The London hard fork, which included the EIP-1559 upgrade, a reductive measure set to reign in Ethereum’s supply growth, went live on August 5 and boosted the price of crypto, which rallied 73.5% during the past 30 days. 

Ethereum chain capacity

According to Buterin, Ethereum post-London chain capacity has increased 9%, due to three equally contributing causes. 

“Turns out the effect is evenly split between three causes: (i) ice age delay, (ii) not-always-full pre-London blocks, (iii) mathematical artefacts of EIP 1559 formula,” said Buterin in a tweet, while sharing the “fun analysis” facts. 

Another fun analysis: why is post-London chain capacity ~9% higher than it was before?

“The London fork delayed the ice age, which had just barely started to take effect when the London fork began,” read the analysis, referring to a mechanism set to increase the difficulty level of puzzles in the Ethereum’s proof of work algorithm, resulting in perpetually longer than normal block times.

The “difficulty bomb” mechanism was designed to exponentially increase the pain of mining the chain, causing it to eventually freeze. 

In addition, the analysis also explained how increasing the Pre-London maximum block gas usage contributes to the chain capacity as it incentivizes miners to include all the available transactions they can find, which are willing to pay more than the base fee.

As far as the mathematical imperfections in the base fee adjustment are concerned, the analysis read that “the EIP 1559 formula is not quite perfect in targeting 50%,” due to a “complex relationship between arithmetic and geometric means.”

“A 0% full block decreases the base fee by 12.5% (multiplies it by 7/8). A 100% full block increases the base fee by 12.5% (multiplies it by 9/8). So what happens if you have a 0% full block followed by a 100% full block? The base fee is multiplied by 63/64,” read the further elaboration, concluding that in order for the base fee to remain constant, the average usage needs to go slightly above 50%.

High gas fees 

The update is eventually expected to solve the most pressing issue plaguing the Ethereum network, but judging by some of the comments on Twitter, burning most of the gas fees involved in transactions didn’t reflect in their reduction as anticipated.

cool, cool, but can you turn the gas knob down some, seems like you left it on 11 since the london fork dropped ngl

The debate surrounding Ethereum’s high gas fees is most likely to continue as their ongoing volatility might not be settled until the final transition to the proof of stake protocol.
