Guys, we need to get this straight: the Cancun upgrade and blobs!
The Fusaka upgrade in December 2025 introduced PeerDAS, which lets nodes check only a portion of the blob data. The blob limit was increased again afterward.
Layer 2 networks only need to make transaction data downloadable by anyone during the period when it needs to be verified, so the results can be checked. The mainnet doesn’t need to store this data forever.
When Layer 2 networks write blob data to the mainnet, blob fees are also paid in $ETH . Currently, 1733.2.
