Vitalik Buterin: @koeppelmann @MeherRoy @drakefjustin @ultrasoundmoney 这个想法是，如果你 51% 攻击一个单独的 DA 层，你可以打破使用它的 L2 的假设。但是如果你 51% 攻击一个组合的结算+DA 层，那么你就不能，因为任何数据不可用的东西都将不属于规范链的一部分

原推：@koeppelmann @MeherRoy @drakefjustin @ultrasoundmoney The idea is that if you 51% attack a separate DA layer, you can break the assumptions of the L2 that uses it. But if you 51% attack a combined settlement+DA layer, then you can’t, because anything with unavailable data will just by definition not be part of the canonical chain
