Fees make it cost-prohibitive for a potential attacker to congest permissionless networks by overwhelming them with large volumes of transactions. Attempts to mitigate MEV, much like regulation in the traditional financial markets, must be implemented with careful consideration of tradeoffs and possible third-order consequences that encourage dark market activity and private transactions pools. Much like how certain forms of frontrunning and information asymmetry persist in traditional finance, we argue MEV will continue to persist and evolve on Ethereum, as well as other smart contract blockchains. Flashbots estimates that miners will earn more than $750 million in additional profit annually from MEV at current rates, the majority of which through pure arbitrage. The bot can then sell its assets, making a tidy profit off of the trade.

At its best, MEV helps make the DeFi markets more efficient by creating financial incentives to rectify price inconsistencies. However, where these opportunities in traditional finance usually contribute to higher barriers to entry for market participants, MEV on Ethereum can contribute to greater levels of market participation, transparency, and efficiency. As the transaction volumes of DeFi applications has grown, the value of trading more quickly than others has also increased. On Ethereum, similar types of behavior to arbitrage, run stops, and advantageous trading at high frequency are beginning to take root in the DeFi markets. In this report, we present a detailed overview of MEV, how it is created, and why MEV remains a significant issue on Ethereum with grave consequences for network stability if left unmitigated.
These solutions make it harder for attackers to identify profitable opportunities in advance. Commit-reveal schemes and encrypted mempools are being explored to conceal transaction details until they are finalized in a block. A user attempting to swap tokens on a decentralized exchange may goatz casino bonus receive significantly less than anticipated because an MEV bot exploited their transaction.
When they strike gold, i.e. find an MEV opportunity, they automatically submit their transactions to validators on Ethereum. The change in the extraction dynamics to tip-based priorities where high-tipped transactions take priority has also increased costs and network congestion. Following the merge and transition to Ethereum proof-of-stake, validators’ incentive to maximize gains has led to significant costs for traders. The shift raised important questions such as whether validators will also exploit MEV to maximize gains leading to increased costs for traders. This competitive advantage allows searchers to offer higher gas prices while keeping overall gas fees lower. In theory, validators are the primary beneficiaries of MEV, as they can ensure the execution of profitable opportunities.

Examples of MEV

• Projects like Flashbots create private communication channels where users can submit transactions directly to miners or validators without broadcasting them to the public mempool.
• For example, the infamous founder of the Investors Exchange (IEX), Brad Katsuyama, and the author of the book “Flashboys,” Michael Lewis, are largely credited to have brought the practices of high-frequency traders into the public consciousness.
• Due to the wide-ranging impacts of MEV on Ethereum, the solutions for managing this type of profit-taking are not only varied but riddled with tradeoffs.
• MEV extraction often favors participants with superior infrastructure, such as low-latency network access and high computing power.
• Frontrunning is when an entity copies a transaction from the mempool and bribes the block producer with a higher gas fee to get their transaction included ahead of the original transaction.
• Block producers can extract MEV from organizing the transactions within a block regardless of fees.

There are upgrades to Flashbots that are expected to improve these various tradeoffs and make Flashbots Auction a more trustless system but none of these upgrades create a network void of transaction ordering manipulation. A prime example of this is the creation of Flashbots Auction, which created unprecedented transparency around the types and volumes of MEV earned on-chain but also made it significantly easier for miners to rely on MEV for additional profits. But this important power (transaction ordering) has given rise to an industry not unlike the high-frequency traders in traditional finance. For example, while Flashbots Auctions has democratized participation in MEV and moved the burden of MEV transaction activity off-chain, it has also accelerated the adoption of this type of profit-taking and routed the majority of this activity to a centralized communication channel. Finally, having a neutral third-party to the relationship between searchers and block producers is anticipated to improve the trust relationship between these two parties and encourage more complex, and perhaps net-positive MEV types to be innovated over the long-run. Under MEV Boost, block builders receive a fee to build the most lucrative blocks for validators and manage the complexities of running between validators and searchers.
But, more importantly, MEV has implications for the security of blockchains. Not only does this create a bad user experience for traders, but it negates the goal of DeFi to accrue value equitably to all users. For instance, trader A conducts a swap or buy order after analyzing current token prices, but trader B frontruns the transaction and triggers a price change before trader A’s transaction can execute. Or, in the worst case, the block producer captures the trade opportunity and censors the initial transaction.

Miners or validators choose and arrange these transactions into blocks for inclusion in the blockchain. Once users start transactions on a blockchain, those transactions go into a pool called the mempool. While MEV generates additional revenue for block producers, its presence creates several systemic issues for users and blockchain networks. Moreover, priority gas auctions (PGAs) involve traders/trading bots sending the same transaction multiple times, increasing the number of transactions gossiped through the peer-to-peer network.

MEV Mitigation Strategies

Block producers or MEV bots can prioritize transactions that capture liquidation bonuses. Arbitrage occurs when price discrepancies exist between different decentralized exchanges. A sandwich attack is a more complex form of front-running where the attacker places one transaction before and one after a victim’s trade. Front-running involves observing a pending transaction and submitting a new transaction with a higher fee or gas price to execute before the original one.
Yet, the existence of multiple relays for MEV protection does discourage transaction throughput from aggregating towards a single centralized gatekeeper. Like Flashbots Auction, the use of alternative transaction relays has negative externalities of its own because these relays often do not have the same guarantees for transaction censorship-resistance as the Ethereum mempool. Flashbots Auction is managed by a centralized entity and as such, the transaction bundles submitted to the Flashbots Auction channel are not censorship-resistant.

• As a result, the term evolved to “Maximal Extractable Value” to reflect the new environment where validators manage blocks.
• MEV Boost does not require changes to the Ethereum protocol and instead relies on trusted relays to protect users and searchers from frontrunning behavior.
• Relying on self-interested network stakeholders to think of the greater good is not a reliable solution for a public ecosystem of Ethereum’s scale.
• Block producers can reorder, include, or exclude transactions within a block to increase their profits.
• Instead of uniformly distributing asset liquidity across the entire price interval, LPs can concentrate their capital by creating targeted depth over a specific price range, such as to a mid-price where the highest amount of trading activity happens, earning them more trading fees.
• Extracting profit from price discrepancies is only possible due to the inefficiencies of the DeFi ecosystem, which over time should begin to lessen as more participants and value start to flow into and out of these applications.

Block producers and other actors in the blockchain network leverage various systematic inefficiencies and opportunities to make profit. The researchers showed how MEV dynamics played out in real-time and detailed its effects on users and the blockchain itself. MEV refers to when block producers adjust transactions to increase profits using front-running and arbitrage methods.
This division lessens the motivation for validators to participate in MEV extraction, thus reducing risks of centralization. This might include reducing the necessary deposit or offering enhanced tools and assistance for individual validators. After Ethereum’s integration, validators are required to deposit 32 ETH in order to take part in the agreement procedure. Although newer, MEV in the NFT space involves buying NFTs at undervalued prices or securing NFTs in high-demand drops. This involves monitoring large trades on DEXs and executing a buy order before the large trade and a sell order after, effectively “sandwiching” it.

Validators may not actively participate in MEV extraction, but they benefit from searchers' efforts. They scan the network using complex MEV bots. These searchers work like treasure hunters on Ethereum. As the number of DEX users grew, a subtle phenomenon known as Miner Extractable Value (MEV) emerged. Decentralized exchanges—DEXs have become popular among crypto users who prefer to maintain complete custody and control of their assets. Understanding and addressing MEV’s implications will be crucial for the future stability and efficiency of decentralized systems.
