Ethereum's Top 3 Upgrades Impacting Gas Fee Dynamics

Over its history, Ethereum has implemented several key upgrades and proposals that have significantly altered or aimed to alter how gas fees function and user experience with them.

The top 3

  1. EIP-1559 (London Hard Fork): Implemented in August 2021, EIP-1559 introduced a base fee that is burned and dynamically adjusts with network congestion, alongside an optional priority fee, making gas prices more predictable but not necessarily cheaper.
  2. The Merge (Transition to Proof-of-Stake): While The Merge in September 2022 drastically reduced Ethereum's energy consumption and improved its supply mechanics, it did not directly lower gas fees, as it was a change in consensus mechanism rather than network capacity expansion.
  3. EIP-4844 (Proto-Danksharding): Introduced with the Dencun upgrade, Proto-Danksharding (EIP-4844) significantly reduces transaction costs for Layer 2 rollups by introducing 'data blobs' for cheaper data availability, paving the way for further scalability.
