Redistribution centralizes power. Redirecting MEV from validators to users requires a new, equally powerful intermediary. This creates a protocol-level cartel that controls transaction ordering and value flow, replicating the extractive model it claims to solve.

Why MEV Redistribution Demands Decentralized Infrastructure
Fair MEV redistribution is the next frontier, but centralized block builders are the bottleneck. This analysis argues that protocols like CowSwap and UniswapX cannot achieve their promise without a decentralized execution layer, examining the risks of capture and the infrastructure required to prevent it.
introduction
THE INFRASTRUCTURE TRAP
The Redistribution Mirage
MEV redistribution fails without decentralized infrastructure, creating new centralized bottlenecks.
Decentralized infrastructure is non-negotiable. A centralized sequencer for redistribution, like a private mempool operator, becomes a single point of failure and censorship. The solution requires permissionless block building and credibly neutral PBS (Proposer-Builder Separation).
The evidence is in adoption. Protocols like Flashbots SUAVE and CowSwap's CoW Protocol architect for decentralization from first principles. They avoid the trap by designing open networks for order flow and execution, not just redistributing captured value.
The metric is liveness. A redistribution system's resilience is measured by its censorship resistance and builder diversity. Without it, user rewards are a temporary subsidy funded by systemic risk, as seen in early centralized cross-chain bridges like Multichain.

WHY REDISTRIBUTION DEMANDS DECENTRALIZED INFRASTRUCTURE
The Centralizing Forces in MEV
MEV extraction is a multi-billion dollar market that, without deliberate design, consolidates power among a few centralized actors, undermining network security and user fairness.
01
The Sealed-Bid Auction Problem
Private mempools and exclusive order flow (EOF) create information asymmetry, allowing sophisticated searchers to outbid the public market. This centralizes block building and extracts value from retail users.
- Key Consequence: ~90% of Ethereum blocks are built by a few centralized builders.
- The Flaw: Reliance on a single, trusted relay creates a central point of failure and censorship.

The Solution: Credibly Neutral Auctions
Protocols like SUAVE and Flashbots Protect decentralize the auction by separating the roles of searcher, builder, and proposer. A decentralized block builder network ensures no single entity controls transaction ordering.
- Key Mechanism: Encrypted mempools with commit-reveal schemes.
- Outcome: Open, permissionless competition replaces backroom deals.

The Problem: Extractive Searcher-Bots
Front-running and sandwich attacks are a direct tax on users, siphoning an estimated $100M+ annually from DeFi traders. This creates a hostile environment where the fastest bot, not the fairest price, wins.
- Victim: Retail traders and predictable AMM swaps.
- Result: Erodes trust in on-chain liquidity.

The Solution: Intent-Based Architectures
Systems like UniswapX, CowSwap, and Across shift the paradigm from transaction execution to outcome fulfillment. Users submit intents; a decentralized solver network competes to fulfill them optimally, capturing MEV for the user.
- Key Benefit: MEV is internalized as better prices (price improvement).
- Entities: UniswapX, CowSwap, Across, Anoma.

The Problem: Proposer-Builder Collusion
Even with decentralized builders, the final block proposer (validator) can collude to censor transactions or manipulate the auction. This is the ultimate centralization risk in PBS (Proposer-Builder Separation).
- Risk: Transaction censorship and maximal extractable value (MEV) theft.
- Current State: Validator set is more decentralized than builders, but incentives are misaligned.

The Solution: Enshrined PBS & MEV Smoothing
Ethereum's roadmap enshrines PBS at the protocol level, removing trust from relays. Coupled with MEV smoothing and MEV burn, this aligns validator incentives with network health by distributing MEV rewards more evenly across all stakers.
- Endgame: Decentralized, resilient block production.
- Mechanisms: Enshrined PBS, EigenLayer, MEV-Burn.

THE BOTTLENECK
The Capture Point: Centralized Block Building
MEV redistribution fails if the block building process itself remains a centralized black box.
Builder dominance creates a cartel. The current PBS model concentrates block building power with a few entities like Flashbots and bloXroute. This centralization reintroduces the exact rent-seeking and censorship risks that MEV redistribution aims to solve.
Decentralized builders are non-negotiable. True MEV fairness requires a competitive market of builders, not a single trusted party. Protocols like SUAVE and MEV-Share attempt to decentralize this layer by creating open, permissionless builder networks.
The validator is the final arbiter. Even with a decentralized builder market, the validator's role in block selection is critical. The proposer-builder separation (PBS) model must ensure validators cannot be bribed to ignore the most value-redistributing block.
Evidence: Flashbots currently builds over 90% of Ethereum blocks. This single-point failure proves that infrastructure centralization precedes and undermines any downstream MEV solution.

counter-argument
THE REGULATORY FALLACY
Objection: Can't We Just Regulate the Builders?
Regulating centralized sequencers or builders fails because it centralizes the very power it seeks to control, creating a single point of failure and capture.
Regulation centralizes the attack surface. Targeting a few large builders like Flashbots or bloXroute creates a single point of failure. Regulators can pressure or compromise these entities, directly controlling transaction flow and censorship.
Decentralized infrastructure is regulation-resistant. A network of permissionless builders and proposers, as seen in protocols like SUAVE or Shutter Network, distributes power. No single entity controls the ordering or content of blocks.
The market routes around control. If regulated builders censor transactions, users migrate to permissionless relays or rollups with decentralized sequencer sets. This is the same dynamic that birthed DeFi after CeFi regulation.
Evidence: The OFAC-compliance rate on Ethereum is ~78% from regulated builders. Transactions simply route through non-compliant builders, proving market-driven circumvention is the default user response.

MEV REDISTRIBUTION
Infrastructure Bets for a Redistributed Future
The extraction of Miner/Maximal Extractable Value is a multi-billion dollar tax on users. Redistributing it requires infrastructure that is decentralized, transparent, and credibly neutral by design.
01
The Problem: The Dark Forest of Private Order Flow
Searchers and builders operate in opaque, off-chain markets, capturing value that should belong to users and validators. This creates a ~$1B+ annual tax and centralizes power in a few firms.
- Opaque Pricing: Users pay hidden costs via front-running and sandwich attacks.
- Centralized Control: A few dominant builders control >80% of blocks on major chains.
- Value Leakage: Protocol and user value is siphoned away from the intended recipients.

The Solution: Decentralized Block Building
Protocols like SUAVE, Shutter Network, and EigenLayer's MEV middleware create competitive, permissionless markets for block construction and inclusion.
- Credible Neutrality: Open auctions replace backroom deals, ensuring fair value distribution.
- Enhanced Security: Decoupling building from proposing reduces validator centralization risks.
- User Benefits: MEV can be captured and redistributed back to users or dapps via mechanisms like MEV-Share.

The Problem: Intents as a New Attack Surface
Intent-based architectures (UniswapX, CowSwap) abstract complexity but create massive, valuable bundles of user transactions. These become prime targets for centralized, rent-extracting solvers.
- Solver Monopolies: A few solvers can dominate, extracting value via opaque fees.
- Fragmented Liquidity: Redistribution requires coordination across chains and applications.
- Trust Assumptions: Users must trust solver honesty without cryptographic guarantees.

The Problem: Validator Centralization via MEV
The promise of MEV rewards incentivizes validators to join the largest, most profitable pools or sell their block-building rights, undermining network decentralization.
- Stake Pooling: Entities with >33% stake can influence transaction ordering and censorship.
- Proposer-Builder Separation (PBS) Failure: If PBS is not enforced at the protocol level, builders and proposers re-centralize.

WHY MEV REDISTRIBUTION DEMANDS DECENTRALIZED INFRASTRUCTURE
TL;DR for Protocol Architects
Centralized MEV extraction is a systemic risk; decentralized infrastructure is the only viable path to sustainable redistribution.
01
The Centralized Relayer is a Single Point of Failure
Current intent-based systems like UniswapX and CowSwap rely on centralized relayers to execute and redistribute MEV. This creates a critical vulnerability: a single entity controls the order flow and the treasury.
- Censorship Risk: The relayer can blacklist addresses or transactions.
- Custodial Risk: Billions in user funds and captured MEV are held in centralized hot wallets.
- Extraction Risk: Nothing prevents the relayer from reverting to pure extraction.

Decentralized Sequencing is Non-Negotiable
MEV redistribution cannot be trusted to a single party. The solution is a decentralized network of competing sequencers, like the model pioneered by Espresso Systems or Astria.
- Liveness: No single sequencer can halt the network.
- Censorship Resistance: Transactions are ordered by a decentralized set.
- Credible Neutrality: The protocol, not a corporation, governs execution.

The Verifier Dilemma & Enshrined Auctions
Without decentralized verification, you cannot prove the relayer redistributed MEV optimally. The infrastructure must enshrine the auction.
- Provable Fairness: Execution proofs must be verifiable by any node, akin to Optimism's fault proofs.
- Market Efficiency: A decentralized solver network (like CowSwap's) competes for bundles, pushing value back to users.
- Protocol-Owned Liquidity: Captured MEV flows into a decentralized treasury or is burned, aligning long-term incentives.

Interoperability is an MEV Vector
Cross-chain MEV (via LayerZero, Axelar) is the next frontier. Centralized bridges are massive MEV sinks. Decentralized infrastructure must be cross-chain native.
- Cross-Domain Arbitrage: Capture value across L2s and rollups seamlessly.
- Shared Security: Leverage validation sets (like EigenLayer) for cross-chain message verification.
- Universal Order Flow: A user's intent on any chain can be routed to the optimal decentralized executor.
