0xKofi: L2 needs to pay gas fees and blob fees for publishing batch transaction data to Ethereum

According to 0xKofi, L2 needs to pay gas fees and blob fees for publishing batch transaction data to Ethereum. Usually, the blob fee is small, and the gas fee is the main part of the cost. However, yesterday the blob fee soared, accounting for 21% of the day's cost of L2 batch publishing. This is because the number of blobs submitted per block briefly exceeded the blob "target".
