The London hard fork is an eagerly awaited upgrade of the Ethereum blockchain that promises exciting new features and improvements. Ethereum, the second-largest cryptocurrency by market capitalization, has been working towards this milestone for some time, and the community is buzzing with anticipation.
So, when does the London hard fork go live? The exact date is scheduled for August 4th, 2021. This highly anticipated event will introduce several important changes to the Ethereum network, including the implementation of EIP-1559. This improvement proposes to change the way transaction fees are calculated, making transactions more predictable and efficient.
One of the most significant features of the London hard fork is the introduction of a new transaction fee mechanism. Currently, Ethereum operates on a volatile fee market, where users bid for transactions to be included in blocks. With EIP-1559, the fee structure will be simplified, with a base fee burned and only an optional tip given to miners. This change is expected to make Ethereum more user-friendly and reduce transaction costs.
In addition to the fee changes, the London hard fork will also bring another important improvement – the delay of the Ethereum “Difficulty Bomb.” This mechanism was designed to make Ethereum mining gradually more challenging, leading to the eventual transition from proof-of-work to proof-of-stake. With the London hard fork, the Ethereum community has decided to delay the Difficulty Bomb for another 12 months, giving more time for the migration to Ethereum 2.0.

Gas Fee Changes
The London hard fork, which is scheduled to go live on the Ethereum network, introduces several important changes, including updates to the gas fee structure.
What are gas fees?
Gas fees are the transaction fees users have to pay to execute operations on the Ethereum network. These fees compensate miners for processing and validating transactions.
Implications of the gas fee changes
The gas fee changes in the London hard fork aim to bring more transparency and predictability to users regarding the cost of executing transactions on the Ethereum network. One of the most significant changes is the introduction of the EIP-1559 proposal.
EIP-1559: This proposal aims to simplify the gas fee structure by introducing a base fee and a tip. The base fee is algorithmically determined based on network congestion, while the tip is an optional amount users can pay to prioritize their transactions.
Benefits of EIP-1559:
- Improved user experience: Users have a better understanding of the transaction fees, leading to more predictable and fair costs.
- Reduced network congestion: The base fee adjustment mechanism helps handle network demand by dynamically adjusting the gas fees.
- Burn mechanism: A portion of the base fee is burned, reducing the supply of Ether (ETH) over time, potentially resulting in deflationary effects.
These changes are expected to make the Ethereum network more efficient, scalable, and user-friendly in terms of gas fees. However, it is essential for users and developers to understand the implications and adjust their strategies accordingly.
Benefits of the London hard fork

Lower transaction fees
The London hard fork, scheduled to go live on August 4, 2021, promises to bring significant changes to the Ethereum network, including lower transaction fees.
One of the major concerns of the Ethereum network has been the rising transaction fees, especially during periods of high demand. The London hard fork aims to address this issue by implementing Ethereum Improvement Proposal (EIP) 1559, which introduces a new fee structure.
Under the current fee structure, users need to bid against each other to get their transactions included in a block. This has led to skyrocketing fees during times of congestion as users compete to have their transactions processed quickly. However, with EIP-1559, a more predictable and stable fee model will be introduced.
With the implementation of EIP-1559, the fee structure will consist of a base fee and a tip. The base fee is algorithmically determined based on network conditions, aiming to automatically adjust to keep blocks at a target size. This means that as the network becomes more congested, the base fee will increase, discouraging unnecessary activity. The tip, on the other hand, is optional and allows users to incentivize miners to prioritize their transactions.
The introduction of this new fee structure is expected to reduce transaction fees for users and make them more predictable. It will also lead to a better user experience by eliminating the need for users to guess how much they should bid to ensure their transactions are processed in a timely manner.
Lower transaction fees will not only benefit individual users but also attract more developers and businesses to build on the Ethereum network. By reducing costs, Ethereum becomes a more cost-effective platform for various decentralized applications, increasing its overall adoption and usage.
In conclusion, the London hard fork with the implementation of EIP-1559 brings hope for lower transaction fees on the Ethereum network. This change will make transactions more affordable and predictable, benefiting both individual users and the wider Ethereum ecosystem.
