Most people think the Cancun upgrade and blobs are simple, but this is where it’s easy to get things wrong:
Ethereum’s Cancun upgrade (Dencun) was activated on March 13, 2024. Its core change was EIP-4844, also known as Proto-Danksharding.
Layer 2 networks only need to make transaction data available for anyone to verify the results during the period when verification is needed; the mainnet does not need to store this data permanently.
When demand for blobs suddenly rises, blob fees will rise too. Layer 2 fees are not always that cheap.
When Layer 2 networks submit blob data to the mainnet, the blob fees are also settled in $ETH .
