Vitalik Buterin Draws Attention to Price of Ethereum Blobs

Ethereum co-founder Vitalik Buterin recently drew attention to the predicted cost of "blobs" on the Ethereum network, highlighting potential economic ramifications. Blobs, introduced by Ethereum Improvement Proposal (EIP) 4844, are data bundles roughly 125 kilobytes in size that can be attached to transactions.

Buterin compared current data transmission costs on Ethereum with projections from Polymarket, a prediction market platform. According to current gas prices, transmitting 125 kB of data (calldata) costs approximately 0.06 ETH. In contrast, Polymarket forecasts the price of blobs to be around 0.001 ETH. This significant disparity suggests that EIP-4844, if implemented, could drastically reduce data storage costs on the Ethereum network.

What is EIP-4844?

EIP-4844 proposes a three-part solution to tackle blockchain's scalability issues. Firstly, it introduces Type-3 transactions, which enable users to attach blobs directly to their transactions. This offloads non-critical information from the main ETH chain, freeing up space and potentially reducing transaction fees.

Secondly, the proposal introduces blob storage, allowing a limited number of blobs to be temporarily stored on beacon nodes (validators) for a specific time frame. Finally, a blob base fee mechanism is implemented to incentivize validators to include these blobs in blocks. This ensures the continued availability of the data while preventing excessive storage that could strain the network.
