Proto-Danksharding and Blob Transactions: Ethereum Dencun Upgrade Aims to Enhance Efficiency and Scalability
- The Dencun upgrade scheduled for March 13, 2024, a major upgrade on the Ethereum network, is aimed at enhancing its blockchain functionality.
- The upgrade introduces proto-danksharding and blob-carrying transactions, which will increase block space and reduce transaction costs, especially for layer-2 networks.
- This upgrade, considered the most significant since the Shapella upgrade in April 2023, follows successful testing on various testnets and is pivotal for Ethereum’s scaling and efficiency.
On March 13, 2024, the Ethereum network will actively engage in a significant upgrade with the Dencun upgrade’s activation, scheduled to take place at slot number 8626176. This pivotal event will introduce a range of technical enhancements to the Ethereum blockchain, marking a major milestone in its continuous evolution.

Introduction to the Dencun Upgrade
The Dencun upgrade is a pivotal development for Ethereum, centering around the implementation of proto-danksharding. This feature will fundamentally alter how data is handled on Ethereum’s layer-2 networks. Proto-danksharding accomplishes this by introducing “blob-carrying transactions.” Unlike standard transactions, these carry additional data, enhancing the network’s data management capabilities without adversely affecting transaction processing efficiency.
This approach actively supports the expanding needs of Ethereum’s layer-2 networks by facilitating transactions that are more efficient and cost-effective. The expected result is an increase in block space by about 2 megabytes, which, crucially, does not negatively impact block processing speeds.
Blob-carrying transactions essentially add an extra piece of data to regular transactions. This additional data capacity is particularly significant for layer-2 solutions like zkSync, Optimism, and Arbitrum, which rely on the Ethereum blockchain for data storage and processing. The Dencun upgrade, by enabling networks to post transaction data on-chain and store actual data in off-chain “data blobs,” expects to significantly reduce transaction costs and boost efficiency.

Technical Enhancements and Proto-Danksharding
Vitalik Buterin, one of the co-founders of Ethereum, has emphasized the importance of such scaling solutions for the success of Ethereum. He believes that Ethereum’s utility and adoption might face significant challenges without an effective scaling infrastructure to lower transaction costs. This upgrade is a step towards addressing these concerns, with the potential to lower rollup costs by up to ten times.
By combining the Cancun and Deneb upgrades, the Dencun upgrade emerges as Ethereum’s most significant advancement since the Shapella upgrade in April 2023. This previous upgrade was notable for allowing the unstaking of Ethereum (ETH) from the Beacon Chain. It was then achieved for the first time since the launch of the proof-of-stake chain in December 2020.
Impact and Significance of the Upgrade
The Dencun upgrade on the mainnet followed a series of successful test deployments on various testnets. This includes Goerli, Sepolia, and Holesky. These tests were crucial in ensuring the upgrade’s readiness for deployment on the main network.
The Dencun upgrade is a significant step in Ethereum’s ongoing development. It aims to make transactions cheaper and more efficient, particularly for layer-2 networks. This upgrade is expected to have a positive impact on the overall Ethereum ecosystem.
