# Ethereum Shanghai Upgrade By [Web3 World ](https://paragraph.com/@web3-world-2) ยท 2023-04-19 --- **_Ethereum Shanghai Upgrade: A Step Forward for the World's Second-Largest Cryptocurrency_** Ethereum is the second-largest cryptocurrency in the world, with a market cap of over $300 billion. It is known for its smart contract functionality, decentralized applications, and open-source development platform. The Ethereum network has been in the process of upgrading to Ethereum 2.0, but before that, there were several smaller upgrades that needed to be made. The Ethereum Shanghai upgrade is one of them. **_What is the Ethereum Shanghai Upgrade?_** The Ethereum Shanghai upgrade, also known as the EIP-1559 upgrade, is a proposal to improve the Ethereum network's transaction fee mechanism. Currently, users have to bid against each other to have their transactions included in the next block. This results in high transaction fees during periods of high network congestion. The EIP-1559 upgrade proposes a new fee structure that includes a base fee that is burned, reducing the overall supply of Ethereum, and a priority fee that users can choose to pay to incentivize miners to prioritize their transactions. This mechanism aims to create a more predictable fee market and reduce transaction fees during periods of high congestion. The upgrade was first proposed in 2018, and after years of development and testing, it was finally implemented on August 5th, 2021, as part of the London Hard Fork. Benefits of the Ethereum Shanghai Upgrade The Ethereum Shanghai upgrade has several benefits for the Ethereum network and its users. Here are some of them: Lower transaction fees: The new fee structure aims to reduce transaction fees during periods of high network congestion, making the network more accessible to users. More predictable fee market: The base fee mechanism creates a more predictable fee market, making it easier for users to estimate the cost of their transactions. Deflationary pressure: Burning the base fee reduces the overall supply of Ethereum, creating deflationary pressure on the cryptocurrency. This could potentially increase the value of Ethereum over time. Incentivizes node operators: The upgrade incentivizes node operators to stay on the network by reducing the volatility of their revenue. This could lead to a more stable network and a better user experience. **_Conclusion_** The Ethereum Shanghai upgrade is a significant step forward for the Ethereum network. It addresses some of the long-standing issues with the network's fee mechanism and creates a more predictable and accessible network for users. The upgrade is just one of the many improvements planned for the Ethereum network, with Ethereum 2.0 still in development. As the network continues to evolve, it is likely that Ethereum will remain a significant player in the world of cryptocurrency and blockchain technology. --- *Originally published on [Web3 World ](https://paragraph.com/@web3-world-2/ethereum-shanghai-upgrade-3)*
