The introduction of EIP-1559 marked a pivotal shift in Ethereum’s economic model, fundamentally altering how transaction fees are structured and distributed. While much attention has focused on user experience and ETH deflationary pressure, one of the most debated consequences has been its impact on miner revenue. This article analyzes the boundaries of miner income post-EIP-1559, offering a nuanced understanding of how fee burning affects earnings—particularly in light of miner-extractable value (MEV).
By examining empirical data, modeling assumptions, and real-world MEV trends, we establish realistic lower and upper bounds for the portion of miner income impacted by fee burning. Contrary to early claims that over 50% of miner revenue would be eliminated, evidence suggests a far more moderate effect—likely between 20% and 35%, depending on MEV visibility and extraction efficiency.
Understanding Miner Revenue Components Pre- and Post-EIP-1559
To assess the true impact of EIP-1559, it's essential to break down miner income into its core components:
- Block subsidies: Miners receive a fixed amount of ETH per block (currently 2 ETH), unaffected by EIP-1559.
- Transaction fees: Previously, all gas fees went directly to miners. Under EIP-1559, the base fee is burned, while only priority fees ("tips") are retained by miners.
- Miner-Extractable Value (MEV): The profit miners can gain by reordering, inserting, or censoring transactions—such as through arbitrage, liquidations, or frontrunning.

Crucially, block rewards and MEV remain untouched by EIP-1559. Only the base transaction fees are subject to burning. Therefore, the real question isn't whether miners lose income—but how much of their total revenue comes from burnable fees versus protected sources like MEV.
The Role of MEV in Mitigating Fee Burn Impact
MEV has become an increasingly significant component of miner income, especially with the rise of decentralized finance (DeFi). As complex on-chain opportunities emerge—like triangular arbitrage across DEXs or collateral liquidations in lending protocols—miners (or more accurately, MEV searchers) capture value through strategic transaction ordering.
Flashbots’ MEV dashboard provides critical insights into this opaque market. By analyzing transaction traces and identifying patterns associated with known MEV strategies (e.g., arbitrage, liquidations), researchers can estimate how much MEV is being extracted—and how much remains hidden.
This visibility allows us to model different scenarios based on the proportion of MEV currently detectable:
Scenario 1: Absolute Lower Bound — Only Identified MEV Counts
In this conservative model, we assume Flashbots captures 100% of existing MEV—an unlikely scenario given known limitations. Even under this assumption, the share of miner income subject to burning remains well below 50%. This establishes a lower bound for burn impact: if all MEV were visible and accounted for, fee burning would still affect less than half of total revenue.
Scenario 2: 67% of MEV Is Detectable
Assuming Flashbots identifies two-thirds of total MEV, we scale observed values by a factor of 1.5. This adjustment reflects the hidden nature of many MEV opportunities—especially those involving private transactions or complex multi-block strategies. Under this model, the effective burn rate on fee-based income increases slightly, but overall miner revenue remains largely insulated due to high MEV contribution.
Scenario 3: 50% of MEV Is Visible
Doubling the measured MEV gives a more realistic picture of current conditions. With DeFi activity growing and arbitrage margins tightening, sophisticated actors use advanced tools to extract value without leaving clear footprints. In this case, MEV accounts for a larger share of total income, further reducing the relative weight of burnable base fees.
Scenario 4: Only 33% of MEV Is Currently Detected
This forward-looking scenario assumes that today’s observable MEV represents just one-third of actual extraction. As DeFi evolves and new protocols introduce novel incentive structures, the “dark forest” of MEV expands faster than monitoring tools can keep up. If true, this implies that MEV could soon dominate miner income, making EIP-1559’s fee burn increasingly marginal in financial impact.

Limitations and Refinements in Current Analysis
While these models provide valuable estimates, several caveats must be acknowledged:
- Non-MEV transactions also pay tips during congestion, meaning miners earn additional income beyond MEV during high-demand periods.
- MEV transactions still pay base fees, which are burned—even though their primary value comes from reordering profits.
- Some MEV is extracted directly by miners via in-house bots or integrated searchers, bypassing public relays like Flashbots entirely. These instances go undetected in current datasets.
These factors suggest that while our estimates are directionally accurate, they may slightly understate both the resilience and adaptability of miner revenue streams.
Debunking the "Over 50% Loss" Myth
Early commentary around EIP-1559 often claimed that miners would lose more than half of their income once base fees were burned. However, this view failed to account for the growing dominance of MEV.
When MEV constitutes 30–50% or more of total miner revenue—and continues to grow—the proportion of income derived from base fees shrinks accordingly. Even if 100% of base fees are burned, the overall hit to miners is cushioned significantly by their ability to capture non-burnable value through strategic block construction.
Thus, credible estimates place the actual burn impact between 20% and 35% of total miner income—not over 50%. Moreover, as Ethereum transitions toward proof-of-stake and proposer-builder separation (PBS), the dynamics will shift again, but the principle remains: value extraction adapts faster than protocol rules can suppress it.
Frequently Asked Questions (FAQ)
What is EIP-1559?
EIP-1559 is an Ethereum improvement proposal that overhauls the transaction fee market by introducing a dynamically adjusted base fee (which is burned) and optional priority fees (paid to validators/miners). It aims to make gas pricing more predictable and reduce fee volatility.
Does EIP-1559 eliminate all miner fees?
No. While the base fee is burned, miners still receive block rewards and any tips (priority fees) users voluntarily add—especially during network congestion. Additionally, they retain full access to MEV opportunities.
How does MEV protect miner income after EIP-1559?
MEV is independent of the base fee mechanism. Since it arises from strategic transaction ordering rather than user-paid gas bids, it remains entirely in the hands of miners (or validators). As MEV grows as a percentage of total income, the relative impact of fee burning diminishes.
Is MEV sustainable in the long term?
While controversial due to issues like frontrunning and user experience degradation, MEV is currently an inherent part of blockchain economics. Efforts like SUAVE aim to decentralize and democratize MEV extraction—but for now, it remains a key revenue pillar for block producers.
Can fee burning ever exceed 50% of miner income?
Only if MEV plays a minimal role and users consistently pay high base fees without adding tips. Given current DeFi activity levels and widespread MEV extraction, this scenario is highly improbable. Realistic models cap burn impact at around 35%.
How does Flashbots help measure MEV?
Flashbots aggregates data from private transaction channels and uses execution trace analysis to identify known MEV patterns—such as arbitrage loops or flash loan liquidations. While incomplete, it offers the best available proxy for estimating real-world MEV volume.
Final Thoughts: A Resilient Economic Model
EIP-1559 represented a bold step toward improving Ethereum’s usability and monetary policy. However, its financial impact on miners was often misunderstood due to incomplete modeling of modern revenue streams.
With MEV, block subsidies, and priority fees all remaining intact—or even enhanced—miner income has proven more resilient than anticipated. Rather than suffering catastrophic losses, block producers have adapted, leveraging new tools and strategies to maintain profitability in a post-fee-burn era.
As Ethereum continues evolving—from rollups to danksharding to full PBS adoption—the interplay between protocol design and economic incentives will remain central. But one lesson stands clear: when value exists on-chain, someone will find a way to extract it.
