For the same Layer 2 network, why did fees suddenly become so much cheaper after the Cancun upgrade?
When comparing Layer 2 fees, distinguish between the Layer 2 network’s own execution fees and the cost of submitting data to the mainnet. Both can fluctuate.
Simply put, blobs have their own fee market: the blob base fee adjusts automatically based on the difference between usage and the target, and is also burned.
When a Layer 2 network writes blob data to the mainnet, it pays the blob fee using $ETH .
