Ethereum Layer-2 Networks Require Responsive Pricing for Scalability, Says Offchain Labs

Edward Felten, co-founder of Offchain Labs, highlighted the necessity of responsive pricing in Ethereum layer-2 (L2) networks during a keynote at EthCC 2026. He argued that such pricing is essential for scaling to billions of users and mitigating the fee volatility that accompanies network congestion. Felten's comments come as Ethereum's scaling strategy evolves beyond mere throughput to include transaction cost predictability for mainstream applications while maintaining infrastructure protection during high demand. Arbitrum One, the largest L2 network with $15.2 billion in total value locked (TVL), has adopted dynamic pricing in January, aiming to align fees with real network bottlenecks. This model is seen as a live test of balancing predictability and efficiency. While responsive pricing offers scalability and transparency, it introduces lower predictability compared to EIP-1559. Julian Kors of Pulsar Spaces noted the tradeoff between predictability and real-time cost alignment, with EIP-1559 excelling in the former and responsive pricing in the latter. Ethereum France's Jerome de Tychey and Status Network's Cyprien Grau acknowledged the potential of responsive pricing to enhance user experience by reflecting actual demand, though they emphasized the need for a model where users are not burdened by gas fees. The debate over fee models coincides with Ethereum's reevaluation of its L2-centric scaling approach, as outlined by Vitalik Buterin in February, who suggested a shift towards mainnet and native rollups for future scalability.
