Introduction
This report systematically analyzes the gas fee structure of the Ethereum blockchain, presenting a dynamic adjustment mechanism under multi-dimensional resource constraints. By combining a supply-side model with demand-side price modeling via fractional Ornstein-Uhlenbeck processes, it derives pricing methods for gas fee derivatives—empowering users to hedge volatility risks and enhance cost predictability.

2. Supply-Side Analysis
- Blockchain Resources: Computational power, storage, and bandwidth are scarce "real estate" in blocks.
- EVM Execution: Gas measures resource consumption for smart contracts, with costs varying by transaction complexity.
Current Fee Structure:
- Base Fee: Automatically adjusted by protocol (burned).
- Priority Fee: Incentivizes miners/nodes.
- Max Fee: Caps user expenditure.
Optimization Insight:
"Multidimensional gas pricing better aligns with heterogeneous resource demands, replacing rigid single-price mechanisms."
3. Demand-Side Modeling
- Fractional OU Process: Captures long memory (Hurst index ≈ 0.38) and mean reversion in gas prices.
- Statistical Validation: Log-normal distribution fits historical data (Fig. 5), supporting model robustness.
4. Gas Fee Derivatives
- Option Pricing: Weighted calls/puts based on cumulative fee deviations from strike prices (Fig. 7).
- Challenges: Non-tradable underlying asset complicates hedging; liquidity risks require market maturation.
5. Risk Assessment
- Model Risk: Extreme congestion or protocol upgrades may disrupt assumptions.
- MEV Risks: Transaction reordering threatens fee stability; strict sequencing mechanisms are proposed.
Frequently Asked Questions (FAQs)
Q1: Why does Ethereum use gas fees?
Gas fees prevent network spam by pricing computational effort, ensuring fair resource allocation.
Q2: How does EIP-1559 improve fee predictability?
By dynamically adjusting base fees to reflect demand, it reduces volatility spikes compared to auction-only models.
Q3: Can gas fees be hedged today?
Not natively, but this report’s derivative models (e.g., options) propose institutional-grade tools for future markets.
Q4: What’s the role of miners in fee markets?
Miners prioritize transactions offering higher priority fees, but multidimensional pricing could optimize their resource allocation.
Q5: How does the fractional OU model differ from traditional finance models?
Its Hurst exponent quantifies long-term price memory, unlike Geometric Brownian Motion’s independence assumption.
