Bitcoin didn’t actually “change”, like the poster’s context of “change”. Or maybe I misunderstood?
What did you understand in the context of “change”? A consensus change such as 21M coins that would result in a hard fork? A change like SegWit and Taproot that would result in a soft fork?
Change the POW algorithm, the network’s security breaks down. Everything about it breaks down, it’s laughable to consider thinking about that kind of “change”.
It's been said by everyone and I also agree that PoW is the greatest choice and that this mechanism shouldn't be changed by force. But we can't be sure for any other innovative ideas, though.
Yes, although i doubt it'll happen anytime soon.
Even if someone found a more efficient way to secure the network same like with PoW, I don't understand why we'd want that. The system works fine this way and the miners become more and more efficient,
if we see this situation morally.
Wouldn't this be a hard fork?
