V God posted a vote on Twitter: "How long does it take for a 51% attack to recover some blocks in order to support out-of-protocol intervention (ie soft fork), stating that the attack chain is illegal, so that users and clients ignore it?" The highest voting option is the shortest "within one day", accounting for 48%. Some netizens asked "How can users and clients ignore people with 51% of block production capacity?" V God replied that if ASIC mining is used, one option is to change the PoW and immediately deprive the attacker of the rights. . Another way is to continue using the soft fork until the attacker runs out of money.
