Ethereum 4844 blobs protocol
Overview
Ethereum 4844 blobs (EIP-4844) are a temporary data structure introduced in the Dencun upgrade to improve rollup scalability. They provide a dedicated space for data availability that is cheaper than calldata and is pruned after a short period. Blobs are not accessible to the Ethereum Virtual Machine (EVM) and are verified via KZG commitments.
Within the DeFi Intel graph, Ethereum 4844 blobs connects to 38 tracked entities, most strongly to Arbitrum, Base, Optimism.

Frequently asked questions
What is Ethereum 4844 blobs?
Ethereum 4844 blobs refer to the blob-carrying transactions defined in EIP-4844, which allow rollups to post compressed transaction data more efficiently. They are part of the proto-danksharding design and are stored temporarily on the beacon chain.
How do blobs differ from calldata?
Blobs are separate from calldata: they are not directly accessible by the EVM, are deleted after about 18 days, and use a different fee market (blob gas). This reduces costs for rollups while keeping Ethereum's execution layer unchanged.
Why did Ethereum introduce blobs?
Blobs were introduced to lower transaction fees for rollups by providing a dedicated, low-cost data availability layer. This prepares the network for future full danksharding while maintaining decentralization and security.
What is Ethereum 4844 blobs connected to?
In the DeFi Intel knowledge graph, Ethereum 4844 blobs is linked to 38 other tracked entities, most strongly to Arbitrum, Base, Optimism.
