Ethereum EIP-1559: How can transaction fees be both cheap and fair?

Source of the Problem

Before the launch of EIP-1559, Ethereum transaction fees (gas fees) were like an endless bidding war. Users could only rely on shouting prices, and when the network got congested, everyone would raise their bids, making the fees an unpredictable “black box”. During the London hard fork in 2021, the Ethereum team decided to completely change this set of rules.

How EIP-1559 Reshapes the Fee System

From auction to smart pricing

Ethereum has introduced a base fee mechanism—no longer allowing users to bid freely, but instead automatically adjusting according to network congestion. Imagine a traffic light system: the base fee rises when the network is busy and automatically decreases when idle. This flexible yet controllable pricing model makes transaction costs traceable.

The most radical innovation: fee burning

The boldest design of EIP-1559 is to permanently destroy the base fee. Previously, all transaction fees went into the pockets of miners/validators, but now the base fee disappears from circulation, directly reducing the total supply of ETH.

What does this mean? Every transaction contributes to the deflation of ETH. The higher the network activity, the more is burnt, which is beneficial for ETH holders in the long run.

Priority fees enable efficiency and incentives to coexist

After the basic transaction fee is burned, how do validators profit? Users can voluntarily pay a priority fee (tip) to “jump the queue” and have their transactions packed faster. This tip is directly rewarded to the validators and is completely market-driven incentive – the more someone is willing to pay, the faster their transaction will be.

Actual Impact

For ordinary users, EIP-1559 brings threefold benefits:

• Transparent Fees: No more guessing how much gas to pay, the basic transaction fees are clear and visible.
• Cost controllable: Unless the network is extremely congested, transaction fee fluctuations are kept within a reasonable range.
• Psychological Optimization: Willing to pay more tips for faster service, and only pay the basic fee if not in a hurry, returning autonomy to the user.

For ETH holders, the deflationary mechanism means a long-term decrease in supply pressure, gradually increasing scarcity.

Summary

EIP-1559 transformed Ethereum's transaction fees from an “auction battlefield” into a “smart adaptive system.” The base fee fluctuates based on network usage, optimizing the predictability of costs; the burn mechanism introduces deflationary pressure on ETH; and priority fees allow users to choose their transaction speed. This upgrade not only addresses the chaos of transaction fees but also cleverly balances network efficiency with token economics through its burn design.
