The Future of Fees: From Transactions to Computations

Paying for block space regardless of computational complexity is a market failure. A simple ERC-20 transfer and a heavy ZK proof pay the same per-byte, creating massive cross-subsidies and misaligned incentives.

• Inefficient Pricing: Complex ops are subsidized; simple ops are overcharged.
• Developer Burden: Hard to predict costs, impossible to optimize for specific resources.
• User Experience: Fees are opaque and volatile, disconnected from actual service value.

Separate execution from consensus/settlement, creating dedicated markets for computation (e.g., rollups, alt-DA). This allows fees to reflect true resource cost (CPU, memory, storage I/O).

• Specialized Markets: Rollups like Arbitrum and zkSync run their own gas auctions.
• Granular Pricing: Projects like EigenLayer and Celestia enable pay-for-what-you-use data availability.
• Predictable Costs: Developers can target specific execution environments with known fee curves.

Users express desired outcomes (intents), not transactions. Solvers compete on execution quality and cost, abstracting gas entirely via Paymaster systems or account abstraction.

• User Abstraction: Protocols like UniswapX and CowSwap hide gas from end-users.
• Sponsored Transactions: Apps pay fees to acquire users, treating gas as a CAC line item.
• Solver Economics: Networks like Across and LayerZero bundle and optimize execution paths.

The ultimate unbundling: raw, provable computation becomes a tradable commodity. Execution environments compete purely on price/performance for specific VM opcodes or proof systems.

• Proof Markets: Services like RiscZero and SP1 sell ZK proof generation by the cycle.
• VM Specialization: Dedicated chains for WASM, EVM, or SVM optimize hardware for specific workloads.
• Universal Settlement: Base layer becomes a cost-efficient verifier and bond marketplace, not a computer.

The Problem: Proof-of-Work security is a one-time cost, but decentralized services (AVSs) need continuous, verifiable compute.\nThe Solution: EigenLayer creates a secondary fee market where restaked ETH is slashed for provably faulty computations, not just invalid transactions.\n- Key Benefit: Monetizes idle validator capital for new services like fast finality layers and decentralized sequencers.\n- Key Benefit: Enables $10B+ TVL to be redeployed as economic security for off-chain compute.

The Problem: Rollup sequencers are centralized monopolies that capture MEV and transaction ordering rights.\nThe Solution: Espresso's decentralized sequencer network sells verifiable, time-bound computation slots for block production, creating a fee market for ordering rights.\n- Key Benefit: Democratizes access to sequencing revenue and MEV, moving it from a private good to a public auction.\n- Key Benefit: Enables shared sequencing across rollups like Arbitrum and Optimism, reducing fragmentation.

The Problem: Generating Zero-Knowledge Proofs (ZKPs) is computationally intensive, creating a high fixed cost for developers.\nThe Solution: Succinct's SP1 acts as a verifiable compute engine, allowing developers to pay only for the proof generation cycles they consume.\n- Key Benefit: Lowers the barrier to ZK adoption by converting capex (running provers) into opex (pay-per-proof).\n- Key Benefit: Enables ~10x faster proof generation for general-purpose programs via GPU acceleration, making ZK-VMs economically viable.

Complex fee markets for CPU, memory, and storage create multi-dimensional MEV. Validators can front-run and sandwich not just trades, but any high-demand computation, from AI inference to on-chain gaming.

• New Attack Surface: Oracles and sequencers become targets for manipulating computational resource prices.
• Centralization Pressure: Entities with superior data on computational demand gain an arbitrage edge, favoring large, sophisticated operators.

Inelastic demand for block space (e.g., a live game or perpetual DEX) meets inelastic computational supply. A single popular app can monopolize a chain's resources, causing fees for all other applications to spike uncontrollably.

• Protocol Cannibalization: One dApp's success can price out all others, killing ecosystem diversity.
• Unpredictable Costs: Makes budgeting for long-running computations (like an on-chain AI agent) financially impossible.

How do you objectively meter and price a unit of 'work'? Unlike gas, computational effort for tasks like ZK proof verification or AI model execution is non-linear and hardware-dependent.

• Verification Cost: The cost to verify a fee calculation could exceed the computation's original cost.
• Manipulable Metrics: Bad actors could craft computations that appear cheap but are resource-intensive, draining validator resources.

Every L1 and L2 (Ethereum, Solana, Monad) will implement its own computational unit and fee market. This fragments liquidity and developer mindshare, reversing composability gains.

• Developer Burden: Requires rewriting dApps for each chain's unique resource accounting model.
• Cross-Chain Chaos: Bridges like LayerZero and Axelar must now translate not just assets, but computational debt and fee entitlements.

Complex computational fee models can obfuscate transaction trails, creating a new form of regulatory arbitrage. Mixing computational payments with transaction fees makes AML/KYC tracing nearly impossible.

• Opaque Cashflows: Distinguishing a payment for cloud compute from a disguised financial transfer becomes a forensic nightmare.
• Target for Scrutiny: Could trigger blanket regulatory action against chains adopting these models, akin to the privacy coin crackdown.

Validators must choose between staking capital for security and allocating hardware for computational services. This could bifurcates the validator set, weakening network security for chains like Ethereum that rely on homogeneous staking.

• Security Dilution: Economic incentives shift from securing the chain to renting out CPU cycles.
• Capital Efficiency Trap: Leads to centralization where only entities large enough to do both (e.g., AWS) can compete effectively.
