After years of anticipation, Ethereum successfully implemented its Dencun upgrade last week, marking a significant milestone in its evolution.
The introduction of nine changes included in the hard fork, with EIP-4844 (Proto-Danksharding) at the forefront, aimed to address rising gas fees on Ethereum's Layer 2s (L2s) by introducing "blobs," a more gas-efficient method for posting L2 transaction data.
Now, a week post-implementation, let's delve into the data to evaluate whether Dencun has lived up to the expectations and how it has transformed Ethereum's landscape.
Impact of Dencun
In the lead-up to Dencun, escalating on-chain activity resulted in surging transaction fees, prompting concerns over the affordability of Ethereum's L2s. While predicting post-Dencun L2 fees proved challenging, initial estimates indicated a potential 90% reduction in fees under similar activity levels.
Following Dencun's deployment on March 13, a brief lag ensued as L2s adjusted their data publishing methods to leverage blobs. However, by the next day, major L2s had incorporated blobs into their operations.
The benefits of Dencun became evident swiftly as L2s began utilizing blobs, leading to a drastic reduction in data posting costs. Notably, ZkSync saw an 89% decrease, Arbitrum experienced a 93% reduction, and OP Stack chains observed costs plummeting by over 98%.

The lowered fees spurred a surge in transaction volumes, with Base achieving a record daily high of 2.1 million transactions on March 16th, marking a 300% increase from pre-Dencun levels.
Looking Ahead
Dencun, particularly EIP-4844, represents a significant step towards addressing Ethereum's scalability challenges in the short term. However, substantial development efforts remain to achieve the ultimate goal of rollup scaling.
Future increases in onchain activity may strain L2 scalability, necessitating solutions like full Danksharding. This upgrade, still years away, aims to dramatically increase the number of blobs per block, enabling Ethereum to support numerous rollups effortlessly.
However, the complex nature of these upgrades, coupled with the need for proposer-builder separation and stateless client development, indicates that it will be years before Danksharding becomes a reality.
In the meantime, Ethereum remains committed to optimizing scalability through incremental upgrades, ensuring a seamless and efficient experience for its users.
By leveraging data-driven insights, Ethereum continues to navigate towards its vision of a scalable and decentralized future.
