The introduction of the EIP-4844 blob has dramatically reduced L1 costs for most L2s, according to data shared by crypto analyst Kofi on platform X. This reduction, exceeding 90%, covers both gas and blob fees associated with batch publishing transactions and gas fees during transaction verification.

Consequently, L2s have been able to lower gas fees charged to users, resulting in a similar reduction in the cost of regular transactions like ETH transfers and Uniswap transactions, making these activities more economical for users.

The impact of EIP-4844 blob implementation extends widely across the industry, benefiting numerous entities. However, some entities, including Manta, Orderly, Lyra, Hypr, and Aevo, have chosen to publish batches on Celestia, opting out of the EIP-4844 blob usage. This decision underscores the diverse preferences among industry players, with some finding alternative methods better suited to their operational needs.

The significant reduction in L1 costs has broad implications for the industry, creating a more cost-effective and efficient environment for transactions. As the industry evolves, further innovations and advancements are expected to build on this foundation.

In conclusion, the EIP-4844 blob implementation has significantly reduced L1 costs across most L2s, leading to lower gas fees and a more economical transaction environment. While some entities have chosen different methods, the benefits of the EIP-4844 blob are clear, paving the way for further growth and innovation in the industry.
