The EIP-4844: What Is Proto-danksharding?
Proto-danksharding is an upgrade to the Ethereum network that represents a key step in the scalability roadmap of the Ethereum blockchain and is part of the broader Dencun upgrade. Proto-danksharding was rolled out via the proposal EIP-4844, while the Dencun upgrade consists of multiple EIPs that each improve different aspects of the network.

EIP-4844 (proto-danksharding) is an upgrade that makes Ethereum more scalable by introducing blobs.
Blobs are a new data structure that temporarily stores large amounts of data outside the EVM, specifically designed for rollups.
Blobs replace calldata as a cheaper way to publish data on Ethereum, without burdening the mainnet with unnecessary long-term data storage.
Blobs have their own pricing mechanism separate from regular transaction fees, ensuring cheap transactions during high network congestion on the Ethereum blockchain.
The number of blobs per block is currently limited to six to prevent spam.
This limit protects the network and ensures stable operation of the pricing mechanism.
Proto-danksharding is a stepping stone toward full danksharding on Ethereum’s roadmap.
It lays the technical foundation for future upgrades with data shards and greater scalability, without compromising on security or decentralization.
