Ethereum (ETH) has undergone a profound transformation since The Merge in 2022, shifting from a proof-of-work to a proof-of-stake consensus mechanism. One of the most significant outcomes? Negative issuance – meaning more ETH is being removed from circulation than is being created. This deflationary trend, initially driven by EIP-1559, is now poised to accelerate further with a potential future upgrade: MEV Burn.
Described by Bankless as the most important Ethereum upgrade since EIP-1559, MEV Burn aims to redirect profits currently captured by arbitrageurs back into the Ethereum ecosystem by burning them – effectively reducing ETH supply and enhancing its scarcity.
Let’s explore how Ethereum became deflationary, the problems posed by Miner Extractable Value (MEV), and how MEV Burn could push ETH deeper into deflation.
The Foundation of Ethereum’s Deflation: EIP-1559
Before diving into MEV Burn, it's essential to understand the groundwork laid by EIP-1559, implemented in August 2021.
Prior to this upgrade:
- Miners received both block rewards and transaction fees.
- Transaction fees were fully paid to miners, incentivizing faster block inclusion but also contributing to gas spikes.
With EIP-1559:
- A portion of transaction fees — known as the base fee — is permanently burned (removed from circulation).
- Users can add a tip to prioritize their transactions, which goes to validators (formerly miners).
- Block rewards still go to validators under proof-of-stake.

This change fundamentally altered ETH economics. Instead of all fees flowing into validator pockets, a significant share is now destroyed with every transaction. According to data from Ultrasound.money, over 3.29 million ETH had been burned by mid-May — a powerful deflationary force.
Moreover, since The Merge, the annual issuance of new ETH dropped dramatically due to reduced block rewards under proof-of-stake. With more ETH being burned than issued during periods of high network activity, Ethereum has entered a state of net-negative issuance.
But can this deflation go even further?
Understanding MEV: The Hidden Cost of On-Chain Activity
Miner Extractable Value (MEV) refers to the profit that validators or bots can extract by reordering, inserting, or censoring transactions within a block. Despite its name, MEV is no longer primarily captured by miners — today, it's mostly exploited by sophisticated arbitrage bots scanning the mempool for profitable opportunities.
Common MEV strategies include:
- Front-running: Bots detect pending trades (e.g., large token swaps) and execute similar trades ahead of them to profit from price movements.
- Back-running: Placing trades immediately after a large transaction to capitalize on expected price changes.
- Sandwich attacks: Combining front-run and back-run trades around a victim’s transaction to maximize profit.
While these activities are technically within protocol rules, they create several systemic issues:
- Increased network congestion: Bots compete fiercely by offering high tips, driving up gas fees for regular users.
- Distorted validator incentives: Validators may favor blocks with higher MEV content, undermining neutrality.
- User experience degradation: Retail traders often face slippage and failed transactions due to MEV activity.
During meme coin frenzies or NFT mints, MEV competition has led to gas prices spiking to unsustainable levels — harming Ethereum’s usability and accessibility.
What Is MEV Burn? A Path to Fairer, More Deflationary Ethereum
MEV Burn proposes a radical solution: instead of allowing validators or bots to capture MEV profits, part of that value would be burned, permanently removing ETH from circulation.
The core idea is simple:
- Identify the MEV present in each block.
- Require validators to pay a portion of that value as a burn fee.
- Destroy those funds — just like EIP-1559 burns base fees.
This mechanism does two critical things:
- It redistributes MEV value back to all ETH holders via increased scarcity.
- It dampens excessive competition by reducing the net profit available from MEV extraction.
Developers refer to this secondary effect as "MEV smoothing" — making MEV returns more predictable and stable rather than volatile windfalls. This could discourage aggressive bot warfare and promote healthier network conditions.
As Bankless noted, if successful, MEV Burn could reduce annual ETH issuance by an additional 400,000 to 500,000 ETH, stacking on top of EIP-1559 burns. Combined with current issuance of around 686,000 ETH per year for staking rewards, this could turn Ethereum into one of the most aggressively deflationary digital assets in existence during high-usage periods.
The Key Enabler: Proposer-Builder Separation (PBS)
Implementing MEV Burn isn’t straightforward — it requires foundational upgrades to Ethereum’s architecture. The most crucial prerequisite is Proposer-Builder Separation (PBS).
Under PBS:
- Block builders are responsible for constructing optimized blocks filled with transactions and MEV opportunities.
- Block proposers (randomly selected validators) simply choose which pre-built block to include in the chain — without knowing its contents in advance.
This separation ensures proposers cannot manipulate transaction order for personal gain. More importantly, it enables transparent measurement of MEV — because the difference between what a builder pays and what they earn reveals the extracted value.
With measurable MEV, the protocol can then enforce a burn rate — for example, requiring builders to burn 50% of observed MEV profits.
Benefits of MEV Burn Beyond Deflation
While supply contraction is the headline benefit, MEV Burn offers deeper systemic improvements:
✅ Fairer fee market: Reduces advantages held by wealthy actors with advanced infrastructure.
✅ Improved decentralization: Prevents centralization pressure from MEV-rich validators.
✅ Enhanced user experience: Lower gas wars mean cheaper and more reliable transactions.
✅ Stronger economic moat: As ETH becomes scarcer, its role as collateral in DeFi strengthens.
In time, predictable MEV returns could even serve as a foundation for new financial primitives — such as stablecoins backed by future MEV yield or lending protocols using smoothed MEV income streams.

Frequently Asked Questions (FAQ)
Q: Is Ethereum already deflationary?
A: Yes — during periods of high network usage, the amount of ETH burned via EIP-1559 exceeds new issuance from staking rewards, resulting in net-negative supply growth.
Q: When will MEV Burn be implemented?
A: There is no official timeline yet. Experts estimate it could take 3–5 years, following full implementation of PBS and further research into fair burn mechanisms.
Q: Who benefits from MEV Burn?
A: All ETH holders benefit indirectly through increased scarcity and reduced inflationary pressure. Regular users gain from lower gas fees and fairer transaction inclusion.
Q: Does burning MEV hurt validators?
A: It reduces potential windfall profits from MEV, but promotes stability. Validators still earn base rewards and tips. Some may welcome predictability over volatility.
Q: Can MEV ever be eliminated completely?
A: No — as long as there are arbitrage opportunities in decentralized markets, some form of MEV will exist. However, MEV Burn aims to minimize its negative externalities and redirect value ethically.
Q: How does MEV Burn compare to EIP-1559?
A: Both mechanisms burn ETH to create deflationary pressure. EIP-1559 targets base fees; MEV Burn targets excess profits from transaction ordering. Together, they form a powerful dual-layer deflation engine.
Final Thoughts: A More Sustainable Ethereum Economy
MEV Burn represents more than just another upgrade — it's a philosophical shift toward aligning incentives across the Ethereum ecosystem. By converting exploitative profit-taking into shared deflation, Ethereum moves closer to becoming a truly resilient and user-aligned platform.
While still in development, the path forward is clear: enhance transparency with PBS, measure MEV accurately, then begin redirecting its value through burns.
As Ethereum continues evolving from "world computer" to "global financial settlement layer," innovations like MEV Burn could prove pivotal in securing its long-term dominance.
