EIP-1559
EIP-1559 is a major upgrade to the Ethereum protocol that changed the way transaction fees are calculated and distributed. It introduced a base fee that is burned with every transaction, effectively making ETH a deflationary asset during periods of high usage.
Additionally, it separated the base fee from the priority fee, which is paid to validators to incentivize faster inclusion. This change made transaction fees more predictable and improved the user experience by reducing the need for complex fee estimation.
It also fundamentally altered the economic model of Ethereum by linking the burn rate to network activity. EIP-1559 is widely considered one of the most successful upgrades in the history of the protocol, demonstrating the impact of tokenomics on value accrual.
It serves as a benchmark for how protocol-level changes can align incentives and improve the long-term sustainability of a decentralized network.
