Cancun-Deneb Upgrade for Ethereum: Significant Improvements, Yet Fee Reductions Not Universal


The much-awaited Cancun-Deneb upgrade for Ethereum (ETH) has been met with excitement and cautious anticipation as it significantly enhances the network’s data logistics and fee structures on Layer 2 (L2) solutions. The upgrade has been hailed for its potential to usher in a new era of reduced transactional fees, but cryptocurrency expert Eric Wall advises against overestimating its impact (source).

Eric Wall’s Perspective: Potential Fee Spikes Despite Upgrade

According to Eric Wall, a well-known figure in the cryptocurrency technology space, the narrative of “dirt cheap” transactional fees on Ethereum’s L2s after Deneb activation may be misleading. While EIP-4844, the enhancement introduced by the upgrade, is expected to improve data usage for Ethereum Virtual Machine (EVM) Layer 2 solutions, Wall warns that fee spikes are still a possibility under certain conditions.

Scaling Limitations and Variable Fee Reductions

Wall notes that even with the maximum capacity of blobspace, L2 rollups post-Deneb activation are only expected to scale up to 100-1,000 transactions per second (TPS). He also stresses that operating at maximum theoretical capacity and consuming all blobspace does not always result in consistently low fees.

Initial observations from the L2Fees tracker reveal a varied landscape regarding fee reductions across prominent L2 solutions such as Optimism, Arbitrum, Starknet, and zkSync Era. Transfer and cross-asset swap fees on these platforms plummeted below $0.01 in equivalent, indicating a significant reduction. However, for certain networks like Loopring, zkSync Lite, and Boba Network, fees remained largely unaffected by the changes triggered by the Deneb upgrade.

Mixed Response from Ethereum Community

The response from the Ethereum community to the Deneb upgrade’s impact on transaction fees has been mixed. While some celebrate the noticeable fee reduction on several L2 solutions, others express concern over the disparities in fee reductions across different networks. The inconsistencies highlight the complexity of optimizing fee structures in a decentralized ecosystem with diverse L2 implementations.


Ethereum’s Cancun-Deneb upgrade has introduced significant improvements in data logistics and fee structures on Layer 2 solutions. However, Eric Wall’s analysis acts as a reminder that the upgrade’s impact should not be overstated, as fee spikes remain a possibility under certain conditions. As the Ethereum ecosystem evolves, achieving consistent and universally low transaction fees across all Layer 2 solutions remains an ongoing challenge requiring further exploration and refinement.

By staying informed and critically assessing the impact of network upgrades such as Deneb, stakeholders within the Ethereum community can navigate the evolving landscape with greater clarity and foresight. As developments unfold, the quest for scalability and affordability in Ethereum’s transactional infrastructure remains a focal point for innovation and improvement.
