With the introduction of the Holesky Testnet on September 28, 2023, replacing the previous Görli Testnet, and the upcoming implementation of the Dencun Upgrade, Ethereum continues its ongoing development. The Dencun Upgrade, named after the consensus (“Deneb”) and execution layers (“Cancun”), aims to improve data availability and lay the foundation for Sharding. Sharding is seen as a key technology to increase Ethereum’s scalability.

The Significance of Dencun

The Dencun Upgrade integrates nine different Ethereum Improvement Proposals (EIPs), collectively representing a comprehensive package of improvements. These EIPs target various areas of the Ethereum network and include measures to increase the efficiency of smart contracts, optimize the management of validators, and introduce a new type of transaction, the so-called “Blob-Carrying Transactions”. A central element among these EIPs is EIP-4844, also known as Proto-Danksharding. It introduces a preparatory form of sharding, marking a crucial step toward scaling the network.

The Impact on Scalability and Efficiency

Proto-Danksharding, realized through EIP-4844, is a central component of the Dencun Upgrade. This concept introduces data blobs — large data sets stored externally from the blockchain and attached to individual blocks. This significantly increases data availability within the network and lays a solid foundation for the implementation of full sharding. This innovation is of great importance for increasing transaction capacity and reducing gas fees in the Ethereum network, detailed further in the next chapter.

Proto-Danksharding — The Technological Revolution in Ethereum

Proto-Danksharding, introduced by Ethereum Improvement Proposal (EIP) 4844, represents a turning point in Ethereum’s evolution. This innovation is the focal point of the Dencun Upgrade, aiming for a comprehensive improvement in the network’s scalability and efficiency. Proto-Danksharding allows for the introduction of data blobs, large data sets stored outside the blockchain and attached to individual blocks. This technological innovation has the potential to significantly increase data availability and lay the groundwork for full sharding — a critical step towards expanding transaction capacity and reducing gas fees.

The Role of Data Blobs

Data blobs are designed as large data packets temporarily stored outside the chain to reduce network load while improving data availability. By attaching these blobs to blocks, a preliminary form of sharding is implemented, allowing for a reduction in the amount of data that needs to be processed on the main chain. This leads to more efficient resource use and a significant reduction in gas fees, as less data needs to be processed on the main chain.

Technical Details and Impacts

Proto-Danksharding introduces a new type of transaction, the “Blob-Carrying Transactions”. These allow blocks to carry data blobs in addition to regular transaction data. The blobs themselves are large, but only a hash of the blob, serving as an identifier, is actually attached to the block. This approach enables efficient processing and storage of data without compromising the network’s performance.

The introduction of Proto-Danksharding and data blobs is a critical step towards Ethereum’s long-term goals for scaling the network. Through these measures, not only is the foundation laid for full sharding, but the efficiency and performance of the network are also improved in the interim. The implementation of EIP-4844 and related technical innovations is thus of great significance for the future of Ethereum and serves as a foundation for further developments towards comprehensive scalability.

The impact of Proto-Danksharding on Ethereum is far-reaching. In addition to the immediate improvement in transaction capacity and reduction of gas fees, it lays the groundwork for a future in which Ethereum can efficiently process even larger volumes of transactions. With the introduction of full sharding in later phases, Ethereum will be able to meet the challenges of a global decentralized financial system and find even broader acceptance and use.

Overall, Proto-Danksharding represents a decisive step in Ethereum’s endeavor to be a scalable, efficient, and powerful blockchain network. The technical innovations introduced with the Dencun Upgrade promise a significant improvement in network performance and lay the groundwork for future development and expansion of Ethereum.
