Note that cross-rollup apps within one zone of sovereignty are still fine. Not also that this also is a limit to the "modular blockchains" vision: you can't just pick and choose a separate data layer and security layer. Your data layer must be your security layer.
请注意，一个主权区域内的交叉汇总应用程序仍然可以使用。不仅如此，这也是对“模块化区块链”愿景的限制：您不能只选择一个单独的数据层和安全层。您的数据层必须是您的安全层。
