According to Odaily Planet Daily, data shared by crypto data analyst Kofi showed that after adopting EIP-4844 blobs, the L1 costs of most L2s have been reduced by more than 90%. L1 costs include Gas and Blob fees for batch publishing transactions and Gas fees for proof verification transactions. As costs have dropped by an order of magnitude, L2 has the ability to reduce the Gas fees charged to users, reducing the cost of conducting ordinary transactions (such as ETH transfers or Uniswap transactions) on most L2s by more than 90%. It is worth mentioning that Manta, Orderly, Lyra, Hypr, and Aevo chose to publish batches on Celestia instead of using EIP-4844 blobs.
