Dencun Upgrade Goes Live: Ethereum’s Stride Towards Lower Fees and Higher Scalability

In a significant development for the Ethereum network, the Dencun upgrade was successfully deployed on the mainnet at 13:55 UTC on March 13. This upgrade marks a pivotal moment for Ethereum, as it is poised to substantially diminish transaction fees for layer-2 networks and bolster the blockchain’s overall scalability.

The Dencun upgrade, hailed as the most consequential hard fork since the Merge, is anticipated to address some of the pressing issues faced by Ethereum users. Layer-2 networks, which operate on top of the Ethereum blockchain to provide faster and cheaper transactions, are expected to benefit immensely from this upgrade.

Arthur Breitman, the co-founder of the Tezos blockchain, weighed in on the upgrade’s impact. Speaking to Cointelegraph, he acknowledged the positive direction of the Dencun upgrade but also highlighted its limitations. “The Dencun upgrade does the bare minimum to extend the data usable by rollups on Ethereum which should lower transaction costs in these L2 solutions. However, rollups built on top of Ethereum remain very throughput constrained and are forced to adopt extreme centralization measures,” said Breitman.

The Dencun hard fork comes nearly a year after the Shanghai upgrade, which was a landmark event that allowed network participants to unstake their Ether following the transition to a proof-of-stake network post-Merge.

Incorporating nine different Ethereum Improvement Proposals (EIPs), the Dencun hard fork is a combination of two significant upgrades: Cancun and Deneb. Cancun focuses on refining transaction management and processing on the execution layer, while Deneb aims to enhance the consensus layer, which is crucial for network participants to agree on the state of the blockchain.

Despite these advancements, gas fees on the Ethereum mainnet remain steep, hovering above 72 gwei. According to Etherscan data, an average swap transaction costs users $86.15 in gas fees, and nonfungible token (NFT) sales incur an average of $145.60 in gas fees. This indicates that while the Dencun upgrade is a step forward, there is still room for improvement in making Ethereum transactions more affordable.

The Ethereum community eagerly awaits the full realization of Dencun’s potential to transform the landscape of blockchain transactions. As the network continues to evolve, it remains to be seen how these changes will shape the future of decentralized finance and the broader cryptocurrency ecosystem.
