Democratic MEV Distribution vs Meritocratic MEV Distribution

Pro: Maximizes Validator Participation & Decentralization

• Distributes MEV rewards equally among all validators in a pool, regardless of their individual performance.
• This model is crucial for smaller validators who cannot compete with sophisticated searchers, ensuring network security by incentivizing broad participation.
• Use Case Fit: Ideal for public goods-focused chains like Ethereum, where minimizing validator centralization is a primary goal.

Con: Creates Principal-Agent Problems & Inefficiency

• Validators have no direct incentive to maximize block value, leading to potential lazy validation.
• High-performing validators subsidize low-performers, which can disincentivize investment in better infrastructure (e.g., high-speed connections, advanced software).
• Use Case Fit: A poor fit for high-throughput, fee-sensitive chains where every block's economic efficiency is critical.

Pro: Maximizes Network Efficiency & Economic Security

• Rewards are tied directly to a validator's ability to capture and include profitable transactions (e.g., arbitrage, liquidations).
• This creates a competitive market for block production, driving down user fees (via tip redistribution) and optimizing chain revenue.
• Use Case Fit: Essential for performance-oriented L1s and app-chains like Solana or Sei, where maximizing TPS and minimizing latency is paramount.

Con: Risks Accelerating Centralization

• Rewards compound for well-capitalized, sophisticated operators, creating a performance gap that smaller validators cannot bridge.
• This can lead to validator set centralization around a few large players (e.g., top 5 validators controlling >33% of stake), posing a long-term security risk.
• Use Case Fit: Problematic for networks in their infancy or those prioritizing censorship resistance above raw performance.

Pro: Censorship Resistance & Decentralization

• Specific advantage: Validator block proposals are built from a permissionless, open marketplace of builders (e.g., Flashbots, bloXroute). This matters for protocols like Ethereum that prioritize credible neutrality and resistance to regulatory capture.
• Real example: Post-Merge, >90% of Ethereum blocks use MEV-Boost, distributing extraction across hundreds of builders.

Con: Inefficiency & Value Leakage

• Specific disadvantage: The builder-searcher-validator separation creates multiple layers of profit-taking, leading to value leakage. The most sophisticated searchers (e.g., using Jito Bundles on Solana as a benchmark) capture the majority of value, not the end users or protocol.
• This matters for protocols where maximizing returned value to users (via MEV redistribution or burn) is a key economic goal.

Pro: Performance & Capital Efficiency

• Specific advantage: Direct integration of searcher/validator functions enables sub-second auction latency and maximal value capture. This matters for high-throughput chains (e.g., Solana's 50k TPS potential) where block space is a competitive commodity.
• Real metric: Jito's tip revenue consistently accounts for a significant portion of Solana validator rewards, demonstrating efficient extraction and distribution.

Con: Centralization & Trust Assumptions

• Specific disadvantage: Relies on a highly specialized, often whitelisted set of searchers or validators with superior infrastructure. This creates centralization risk in the block production layer.
• This matters for new L1s or L2s where establishing validator set decentralization is critical for security and community trust. It can lead to a "rich get richer" dynamic among validators.
