According to Wu Shuo, Vitalik published an article discussing the future development direction of Ethereum, including gradually increasing blob capacity and ultimately achieving a complete vision of data availability sampling of 16 MB per slot data space; improving L2 to better utilize the owned data space. Vitalik pointed out that currently only the DeGate Fuel ArbitrumOne dydxv3 zkSyncLite has reached the first stage of Rollup (limited training wheels). In the future, it will only be considered a Rollup when the project actually reaches at least the first stage. Ethereum should be expanded to other application areas, including identity, reputation and governance.
