Du Jun: If the DA layer of the sovereign Rollups L2 expansion plan is Bitcoin, the transaction confirmation time "will have to wait for more than 5 m

Du Jun, CEO and executive director of New Fire Technology, posted on social media that for Layer2 expansion plans similar to Sovereign Rollups, if the DA layer is Bitcoin, it takes more than 5 minutes from transaction initiation to DA layer confirmation. This is unacceptable for transactions and businesses that are sensitive to transaction delays, such as those using real-time data such as coin prices. Therefore, even if Sovereign Rollups achieves the separation of DA and Settlement, there are still many limitations in business scalability and universality.
