It has been over a full year since the Ethereum network witnessed the launch of the important Dencun update in March 2024. While The Merge (September 2022) stole the spotlight with Ethereum's transition to proof of stake, Dencun was a critical update with practical and tangible effects we are experiencing today in 2025.
The primary goal of Dencun was to make user interaction with Layer 2 networks on Ethereum cheaper and more efficient. This was largely achieved through the introduction of the "Proto-Danksharding" feature and the "Blobs" mechanism for data storage.
And after more than a year since this update, the numbers don't lie:
Data and observations in 2025 clearly indicate a significant and ongoing reduction in transaction fees on most prominent Layer 2 networks (such as Arbitrum, Optimism, zkSync, Base, and others). This drop in costs is a direct result of how data is processed and stored more efficiently thanks to Dencun.
What does this fee reduction mean in 2025?
* More accessible decentralized applications (dApps): The use of DeFi applications, Web3 games, and NFT platforms on Layer 2 networks has become much cheaper, opening the door to a wider user base.
* Promoting Layer 2 adoption: Lower fees encourage more users and developers to switch to and use Layer 2 networks, alleviating pressure on Ethereum's main chain.
* A step towards comprehensive expansion: Dencun was just one step in Ethereum's larger roadmap for scaling, but its impact on reducing costs was a strong push towards making the network capable of serving billions of users in the future.
In 2025, we clearly see that the Dencun update in 2024 was not just a technical upgrade, but an effective investment in the future of scalable and accessible Ethereum for everyone. The numbers around transaction costs tell a large part of the story!
