The Ethereum Dencun upgrade will introduce "Proto-DankSharding," aimed at reducing transaction costs for Layer 2 blockchains and addressing scalability. This upgrade forms a key part of Ethereum's broader strategy to enhance scalability and reduce transaction costs for its users. This article provides a brief overview of the technical components, development process, and potential impact of the Dencun upgrade on Ethereum’s transaction capacity and cost efficiency.
Dencun Core Feature: Proto-DankSharding
Proto-DankSharding is the core enhancement in the Dencun upgrade, designed to lower transaction costs for Layer 2 blockchains and reduce data availability costs, thereby tackling critical scalability challenges. It lays the foundation for the eventual implementation of "Danksharding," further amplifying these benefits.
Development Process
The Dencun upgrade is a shorthand for Cancun-Deneb, where Cancun focuses on improving network scalability at the execution layer and Deneb targets enhancements to Ethereum's consensus layer. The centerpiece of this upgrade is EIP-4844, alongside other improvement proposals including EIP-1153, EIP-4788, EIP-6780, and EIP-7514.
The deployment of the Dencun upgrade involves activation across various testnets. After successful activations on the Goerli and Sepolia testnets at the end of January, the final testing phase was completed on the Holesky testnet on February 7.
The final version of Ethereum clients with Dencun functionality is expected to be released by February 22, giving validators approximately two weeks to install the updated client versions on their nodes.
Currently, Ethereum developers have shared information about Geth v1.13.12, also known as Edolus, and are planning the Dencun upgrade on the mainnet for March 13 at 13:55 UTC, at block height 8,626,176. This date requires approval from developers and confirmation via the open-source platform GitHub.
Technical Innovations in the Dencun Upgrade
One of the most notable technological innovations introduced by the Dencun upgrade is the "blob," designed to temporarily store and compress large volumes of transaction data off-chain through Ethereum nodes, reducing storage and processing demands. Blobs can hold data temporarily—only necessary for short-term transaction validation—after which the data can be deleted to prevent network storage overload. The security and effectiveness of the data handling process are ensured through cryptographic techniques that detect data alterations.
According to previous reports, Proto-Danksharding will limit the number of blobs per block to 16, with each blob not exceeding 128KB in size. As a result, block space is expected to increase by approximately 2MB. This additional data space will allow optimistic and zero-knowledge rollups to publish proofs of transaction data on-chain, delivering actual data via blobs instead of "calldata." Blob data will be deleted after two weeks, whereas "calldata" remains indefinitely stored on the Ethereum blockchain.
Impact on Transaction Capacity and Costs
Following the implementation of the Dencun upgrade, Ethereum's transaction processing capacity is expected to significantly improve, ultimately enabling the network to handle 30,000–100,000 transactions per second. This enhancement is crucial for Ethereum’s ability to support the growing ecosystem of dApps and users.
Moreover, the Dencun upgrade is projected to reduce both on-chain and rollup-related costs on Ethereum by a factor of 10, greatly improving scalability and cost-efficiency. Specifically, it could lower Ethereum transaction fees from the current average of $0.23 to just $0.02. Such a reduction may accelerate adoption along Ethereum’s rollup roadmap, while lower costs make Layer 2 solutions more attractive and competitive.
Since EIP-4844 can reduce the block space fees paid by rollups by over tenfold, the Dencun upgrade may lead to a short-term decline in fee revenue for the Ethereum protocol. The success of the upgrade can be measured by several indicators: L2 adoption of blob transaction types; reduced L2 sequencer fees; lower transaction fees on L2s; increased blob fees making "spam" data economically unfeasible; and long-term adoption of Ethereum as a data availability (DA) layer rather than competing alternatives such as Celestia.
Impact on Validators and Staking Operators
Expanding staking services such as Lido and Rocket Pool—as well as staking volume from major players like Coinbase, Binance, and Kraken—has been one of the most important areas of active research within the Ethereum community, aimed at enhancing network security.
Ebunker believes that as ETH staking volume increases, greater pressure is placed on the consensus layer. A large number of validators leads to an increase in gossip messages and growth in beacon state size—archived Lighthouse nodes already occupy up to 16TB of storage space.
While increasing the maximum effective balance (currently 32 ETH) could slow down message volume and beacon state growth, implementing such changes requires a delicate balance, as it would raise the barrier for solo Ethereum validators.
The Dencun upgrade is already addressing this issue, with certain solutions—such as EIP-7514, which increases the Max Epoch Churn limit—slowing the rate at which new validators can join the network.
Market Impact of the Dencun Upgrade
The Dencun upgrade could influence the market value of the Ethereum network in several key ways:
Enhanced Network Capabilities: The Dencun upgrade can significantly boost Ethereum’s transaction processing capacity and reduce costs, attracting more developers and users into the Ethereum ecosystem. Improved network efficiency and higher adoption rates may drive demand for ETH, potentially impacting its price positively.
Investor Perception: A successful Dencun deployment could strengthen investor confidence in Ethereum’s long-term viability and in the development team’s ability to execute complex upgrades. This perceived reliability and forward momentum may enhance Ethereum’s appeal as an investment, potentially increasing its valuation.
Market Hype and Sentiment: The cryptocurrency market is highly sensitive to investor sentiment. Anticipation of positive outcomes from the Dencun upgrade or market reactions to its successful implementation could trigger short-term price volatility, as traders and investors adjust their positions based on expectations about Ethereum’s capabilities and market position.
With the Dencun upgrade successfully activated on Ethereum testnets and scheduled for full mainnet rollout in March, Ethereum’s transaction processing capacity and efficiency are set to improve dramatically. Overall, the Dencun upgrade represents a major evolution for Ethereum, addressing immediate and long-term challenges related to scalability, security, and efficiency.
EIPs within this upgrade targeting optimized data availability and staking operations can significantly enhance network performance and user experience. By implementing Proto-Danksharding and introducing blobs to tackle pressing challenges faced by blockchain networks, the Dencun upgrade marks a milestone in Ethereum’s ongoing efforts to improve scalability and reduce transaction costs.
