What is Ethereum London Upgrade? How to Buy ETH in 2021?

Updated: Sep 9, 2021

With the Ethereum London upgrade, what has changed in its blockchain network and how to buy ETH in 2021.


The most anticipated Ethereum London upgrade was activated on 5 August 2021. The upgrade is formally known as London hard fork which means an unchangeable permanent modification on the blockchain. The community added London before the hard fork because they want to name it after the city where Devcon international developer’s conference was hosted.

What is Ethereum London Upgrade?

The software upgrade brought a few big and necessary changes to the world’s second-largest cryptocurrency. Ethereum (ETH) users have faced lasting problems with scaling and its unreasonable transaction fees. Due to the recent surge in Non-Fungible Tokens (NFTs) that are built on the Ethereum blockchain, these problems have become worse. The main aim of the London upgrade is to create a transparent fee structure for ETH users. Let us explore the Ethereum improvement protocols in this article.

ETH London Upgrade

The Ethereum London upgrades are implemented to make the blockchain more efficient and make the fee structure transparent. This upgrade or London hard fork consists of five Ethereum Improvement Protocols (EIPs). You might have heard of only one protocol which is EIP 1559, but there are four more protocols included in the upgrade. Let's look all these five EIPs and how they make the blockchain more efficient.

EIP 1559

EIP 1559 is the most popular update of the London hard fork. The two components of EIP 1559 are the reasons for the excitement and controversy in the community. First, it adds a base fee to all the transactions on the Ethereum blockchain. That might sound complex, but it helps users estimate the fee. Before the update, the system had to rely on the live auction. As a result, many people has overpaid the transaction fees.

The second component of EIP 1559 is that the miners will not be able to get the fee. Most of the gas fee is burned. When gas fee is burned, it means that the ETH is sent to an isolated address and removed from active circulation. Because of this, deflationary effects will be created on the network, and the value of existing Ethereum increases.

EIP 3198

EIP 3198 is a sister proposal to EIP 1559. It extends the user experience improvements to smart contracts. Smart contracts are a part of the computer codes which carry out the instructions on the Ethereum blockchain. Decentralized finance (DeFi) applications are able to remove the middlemen with the help of smart contracts. This EIP protocol makes sure users do not overpay for the transactions carried out based on smart contracts.

EIP 3529

EIP 3529 can also make a big impact on the network. This protocol removes the refunds for certain opcodes. Currently, you can get a refund on gas fee when cleaning up after yourself on the network. Cleaning up is needed because smart contracts and related data will clog up the network.

People fill up the network with unnecessary data when the gas fees become low. When the gas fees become high, they will clear all the unnecessary data to get those refunds back. By removing the refunds through this protocol, EIP 3529, the network will become more stable.

EIP 3541

EIP 3541 will not do anything by itself. This update reserves the space within the network to create new smart contracts. It makes the process of creating new functionality to the Ethereum virtual machine a smooth experience, without affecting or disturbing the existing ones.

EIP 3554

EIP 3554 is the standard of the London upgrade. This protocol is set to release a ‘difficulty bomb’ in December 2021. It makes the process of solving complex cryptographic problems even more difficult to earn ETH. As a result, the network will become slower. Once EIP 3554 becomes fully operational, the Ethereum blockchain will move from proof-of-work to proof-of-stake model. To secure their ETH, miners have to dedicate their ETH to the network.

Impact on ETH price

The Ethereum London upgrade was expected to reduce the gas fees or transaction fees. Gas fees or transaction fees is the fees required for verifying or authenticating the Ethereum transactions.

The update reduces the gas fees by burning most of those that are involved in the transactions and take them out of the active circulation. The supply of Ether will decrease if the gas fees are burned. As a result of lesser Ethereum tokens, it may become more valuable.

According to Ethereum Blockchain Explorer's burn tracker, more than 67,700 ETH are burned at the rate of 2.37 ETH/minute till August 20. Because of burning the large amount of Ethereum, a deflationary effect is created. As a result, the price of Ethereum is increasing.

The price of Ethereum is moving around $3,200 USD according to CoinMarketCap on August 20. Though the ETH price has increased after the London update, the gas fee hasn’t really been reduced yet. Experts are saying that it takes more time to reduce the gas fee and it is expected to reduce overnight.
