The Cost of Centralization in Today's Proof Generation

Rollups like Arbitrum and Optimism rely on a single, centralized sequencer to order transactions. This creates a critical vulnerability where $10B+ TVL can be frozen or censored by a single entity. The promise of decentralization is deferred to a vague future roadmap.

• Censorship Risk: The sequencer can front-run or block user transactions.
• Liveness Risk: A single server outage halts the entire chain.
• Economic Capture: MEV is extracted and retained by the core team.

zk-Rollups like zkSync Era and Starknet outsource proof generation to a small set of trusted, high-performance provers. This centralizes the cryptographic security assumption and creates a ~$100M+ hardware moat that stifles permissionless innovation.

• Trust Assumption: Users must trust the prover's setup and execution.
• Cost Inefficiency: Lack of competition leads to ~30% higher costs passed to users.
• Innovation Stagnation: New proving systems (e.g., RISC Zero, SP1) struggle to gain market share.

Even 'decentralized' rollups are bottlenecked by data availability layers like Ethereum or Celestia. High demand leads to spikes over $1M/day in L1 posting fees, creating a volatile and expensive cost structure that is passed directly to end-users.

• Cost Volatility: User fees are unpredictable and tied to L1 congestion.
• Throughput Limit: Final throughput is capped by the DA layer's bandwidth.
• Centralized Fallbacks: Teams often use centralized data committees as a temporary crutch.

Protocols like Polygon and Avalanche promote decentralized governance while core infrastructure upgrades are unilaterally executed by the founding team. Token holders have no real say over sequencer logic, prover selection, or fee models, rendering governance a marketing feature.

• Execution Centralization: Code upgrades are pushed via multi-sigs, not on-chain votes.
• Parameter Control: Critical economic parameters (e.g., sequencer cut) are set off-chain.
• Vendor Lock-in: The core team maintains control over the proving stack.

Relying on a single prover like EigenDA's whitelist or a centralized sequencer creates systemic risk. A failure or compromise halts the entire chain.

• Security Cost: A single exploit can drain $1B+ TVL ecosystems.
• Innovation Cost: New ZK-VMs and custom circuits are bottlenecked by a handful of trusted entities.
• Sovereignty Cost: Protocol upgrades and forkability are controlled by the prover operator.

Centralized provers extract rents from the L2/L3 ecosystem, turning security into a revenue center. This distorts incentives and increases end-user costs.

• Fee Extraction: Prover fees are a ~20-30% margin on top of base L1 settlement costs.
• Vendor Lock-in: Custom circuits and tooling create dependency, stifling competition.
• Opaque Pricing: Lack of a competitive market means teams can't shop for better rates or performance.

Batch processing in centralized queues adds hours of delay to proof generation and L1 finality. This cripples capital efficiency and user experience for DeFi and gaming.

• Time Cost: Proof finality can take 4-12 hours, vs. a potential ~10 minutes in a decentralized network.
• Capital Cost: Bridges and exchanges require larger safety margins, increasing costs.
• UX Cost: Users and apps cannot trust "instant" confirmations, reverting to slow L1 assumptions.

Decentralized proof networks like RiscZero, Succinct, and GeoL2 treat compute as a commodity. This creates a verifiable compute market.

• Security: 100s of provers replace one, requiring collusion for failure.
• Economics: Open bidding drives costs toward marginal electricity + hardware.
• Innovation: Any developer can deploy a new ZK-VM and find provers to run it, unbundling innovation from infrastructure.
