Ethereum’s Dencun Upgrade: Will Roll-Ups Fade Away?

Dencun and EIP-4844

Ethereum is planning a major upgrade called Dencun in mid-March. This upgrade will include the implementation of EIP-4844, which introduces “blob-carrying transactions.”

These transactions allow users to attach large amounts of data (blobs) to their transactions at a much lower cost than traditional Ethereum transactions.

Impact on Layer-2 Solutions

Ye Zhang, co-founder of Scroll, a layer-2 project, is optimistic about Dencun’s potential benefits, especially the lower transaction fees. However, he also highlights the challenges it could pose for existing layer-2 scaling solutions that use roll-ups.

EIP-4844 aims to reduce the need for layer-2 transactions by introducing blob transactions. This could potentially compete with roll-up platforms like Arbitrum and Optimism.

Advantages and Disadvantages

Blob inscriptions have their advantages, such as lower costs for transactions with large amounts of data. However, roll-ups still have distinct advantages, including superior scalability and security inherited from the Ethereum mainnet.

Market Impact

The impact of EIP-4844 on Ethereum and layer-2 solutions remains to be seen. However, the Ethereum community is excited about the upgrade and expects it to boost ETH prices.

Ethereum is currently trading above $3,800 and has seen significant gains in the past week. Experts predict further gains in the coming days.


Dencun and EIP-4844 have the potential to significantly impact the Ethereum ecosystem. While blob inscriptions could pose challenges to roll-ups, the advantages of both solutions will likely coexist in the future.
