In proof of work, if somebody picks up 51 % of the mining power and starts attacking the chain, you have like two options. You can either keep the chain operating under tislike weird censor condition, or you can choose to change the mining algratem. In bit coin, the only other type of minin algratem you could consider is something where there's general purpose kind of computers available. But what if your htacker had thought a step ahead of you, and they also no 51 % of minabll gp us under their control? There's just literally no other computing device you can move to.
