The upgrade, officially designated EIP-7781, would also ramp up the blockchain’s capacity to handle blobs, which are dedicated data-storage chambers used by affiliated layer-2 networks to stash transaction records. The change would effectively increase the number of blobs per block to nine from six, providing more space for layer-2 chains like Arbitrum and Optimism to post data to Ethereum.
