What is EIP-1559?
EIP-1559 is an Ethereum Improvement Proposal that was implemented as part of the "London" hard fork on August 5, 2021. Its main purpose was to reform Ethereum's transaction fee mechanism and introduce a fee burn system.
Key Features
- Fee Burn Mechanism: EIP-1559 introduced a system where a portion of every transaction fee (the "base fee") is burned, meaning it is permanently removed from circulation. This base fee fluctuates based on network activity and demand for block space. The remaining part of the fee, called the "priority fee" or "tip," is given to the validator (or previously, the miner) who includes the transaction in a block34.
- Predictable Fees: The upgrade aimed to make transaction fees more predictable for users, reducing the uncertainty and inefficiency of the previous "first price auction" model564.
- Deflationary Pressure: By burning a portion of transaction fees, EIP-1559 can reduce the overall supply of ETH, especially during periods of high network activity. This mechanism can make ETH more scarce and potentially deflationary if the amount burned exceeds the new issuance from staking rewards73.
- Protocol-Level Value: The fee burn ensures that ETH's economic value is enshrined at the protocol level, aligning incentives for network participants and ETH holders3.
Summary Table
EIP-1559 is considered one of the most significant upgrades to Ethereum, fundamentally changing how transaction fees are handled and introducing a deflationary mechanism to the ETH supply
