EIP-4844, known as Proto-Danksharding, introduces a new transaction type that carries “blobs” of data, decoupling data availability from the Ethereum Virtual Machine. This architectural enhancement significantly reduces transaction costs for Layer-2 rollups, making the network more accessible and efficient for end-users and developers. The upgrade has already demonstrated a 10-100x reduction in L2 transaction costs, enabling a substantial increase in overall network throughput via scaling solutions.
Prior to EIP-4844, Layer-2 solutions utilized Ethereum’s calldata for data availability, which incurred high gas costs and limited throughput, creating a bottleneck for widespread adoption. This architectural constraint resulted in elevated transaction fees for rollup users, hindering the economic viability of many decentralized applications. The prevailing engineering challenge centered on providing a cost-effective and scalable data availability layer without compromising the security guarantees of the mainnet.
EIP-4844 alters the data availability layer by introducing dedicated, temporary storage for large data chunks on the consensus layer, known as blobs. This mechanism reduces the cost of posting rollup transaction data to Ethereum, thereby directly lowering fees for Layer-2 users. The implementation of a dynamic blob gas market, analogous to EIP-1559, stabilizes demand for data availability and ensures efficient resource allocation. This structural change empowers Layer-2 networks to achieve significantly higher transaction volumes and lower operational costs, fostering a more robust and scalable ecosystem for developers building next-generation decentralized applications.

EIP-4844 serves as a foundational step toward full Danksharding, a roadmap envisioning 100,000 TPS through expanded blob capacity and data availability sampling. This trajectory unlocks new categories of dApps requiring high throughput and low latency, such as advanced on-chain AI inference and privacy-preserving computation. The enhanced modularity and cost efficiency position Ethereum as a global settlement layer, attracting further institutional capital and driving innovation at the application layer.
EIP-4844 is a pivotal architectural upgrade, fundamentally re-aligning Ethereum’s scaling capabilities and cementing its position as the foundational infrastructure for the decentralized web.
