According to Blast's explanation of the multi-signature security issue, Slow Fog founder Yu Xian commented on X platform: "I have never seen such a funny security explanation. A future L2 with only smart contracts is compared with those real L2 multi-signature security models... Originally, many security personnel (including me) raised concerns about Blast's excessive permissions, just to remind players to be aware of the risks. The objective fact is that we acknowledge it, but there is no need to come up with such a funny security explanation."
