Quick Reference: The Cancun Upgrade and Blobs
Blob data is stored only by consensus layer nodes for about 4096 epochs, or roughly 18 days, after which it is deleted.
EIP-4844 introduced a transaction type that carries blobs. Each blob consists of 4096 data units of 32 bytes each, or about 128 KB.
When demand for blobs surges, blob fees will rise too. Layer 2 transaction fees won't always be that cheap.
When Layer 2 networks submit blob data to the mainnet, they pay blob fees in $ETH .
