EIP-4844 Blobs

Definition ∞ EIP-4844 blobs are temporary, low-cost data segments introduced by Ethereum Improvement Proposal 4844, also known as proto-danksharding. These blobs allow Layer 2 rollups to post large amounts of transaction data to the Ethereum mainnet more cheaply and efficiently than traditional call data. They are designed to significantly reduce transaction fees and increase throughput for scaling solutions.
Context ∞ EIP-4844 blobs are a pivotal upgrade for Ethereum, directly addressing the high data costs currently faced by Layer 2 rollups. The current discussion centers on their successful deployment and the subsequent reduction in rollup transaction expenses, which is expected to spur wider adoption of Layer 2 networks. A key development to observe is the impact of these blobs on overall network scalability and the economic models of various rollups.
