For builders working with Layer 2 (L2) solutions, one challenge has consistently slowed development progress: decoding the complex data streams used for transaction settlement onto the L1 chain. This process is not only time-consuming but also requires significant technical expertise.

Thank you to all those who provided input and review on this piece, including Julian Ma, Soubhik Deb, Barnabe Monnot, Max Resnick, Mallesh Pai, Davide Crapis, Ed Felten, Roberto Bayardo, Potusz, and the Blocknative team. On Thursday, June 20, 2024, the Blob Base Fee spiked to 8,000 GWEI, making blobdata (type 3 transactions) more expensive than calldata (type 2 transactions) for the second time since the Dencun upgrade. During the inversion event, L2s incurred an estimated overpayment of ~166 ETH (approximately $550,000 USD) by including data in batches sent to Ethereum as blobdata instead of calldata. What happened? Why did we see another spike similar to the blobscription craze?
