The Ethereum network witnessed the deployment of its London upgrade on the Ropsten testnet on June 24. This upgrade consists of the highly anticipated Ethereum Improvement Proposal (EIP) 1559.
Following the launch on the Ropsten testnet, the London upgrade will be deployed on Ethereum’s Goerli, Rinkeby and Kovan testnets at weekly intervals. This is one of the important steps in the roadmap to implement a proof-of-stake (PoS) consensus on the Ethereum network, also known as Ethereum 2.0.
The London upgrade brings five EIPs that are going to be deployed on the testnets — EIP-1559, EIP-3198, EIP-3529, EIP-3541 and EIP-3554. The hotly debated EIP-1559 proposal is a transaction pricing mechanism that consists of a fixed per-block network fee that is burned and allows the dynamic expansion and contraction of block sizes to address the congestion issue.
Through this mechanism, there will be a discrete base fee for transactions that will be included in the next block. For applications and users who want to prioritize their transactions on the network, a tip called “priority fee” can be added to incentivize the miner for faster inclusion. While the miner pockets this tip, the base fee for the transaction is burned. This entails that until the transition to a PoS model is complete, in addition to the 2 Ether (ETH) per block that miners receive, they would also be receiving the tip for prioritizing transactions.
James Beck, director of communications and content at ConsenSys — a blockchain technology company backing Ethereum’s infrastructure — discussed with Cointelegraph the impact of burning the base fees on the network:
“Burning the base fee should put a deflationary pressure on the issuance of ETH, though modeling exactly how deflationary is difficult since you have to project variables like expected transactions, and, even harder to predict, expected network congestion. In theory, the more transactions that…
