Reduced L1 costs with EIP-4844

As part of its roadmap, Starknet aims to significantly reduce transaction costs. 

Currently, L1 (Ethereum) data accounts for the majority (95%) of transaction costs on Starknet. This EIP, together with the supporting changes in Starknet’s protocol, should result in a reduction in the cost of Starknet data storage on L1. Starknet L1 data will be sent as 4844 blobs, which are expected to be much cheaper than call data.
