EIP-1559 Upgrade

Upgrade

The Ethereum Improvement Proposal 1559 (EIP-1559) fundamentally altered the transaction fee mechanism on the Ethereum blockchain, shifting from a first-price auction to a base fee plus priority fee model. Introduced in August 2021, this upgrade aimed to improve transaction predictability and reduce gas price volatility, addressing longstanding concerns within the Ethereum ecosystem. Prior to EIP-1559, users competed to have their transactions included in a block by offering increasingly higher gas prices, often leading to inefficient fee markets and unpredictable costs. The core innovation involves a dynamically adjusted base fee, burned with each block, which incentivizes network participation and introduces deflationary pressure on Ether.
