Re: Hearn's Worst Case Scenario: Checkpoints in XT to "ignore the longest chain"
Wow. Bitcoin XT is now an altcoin? 
Thats what i wonder too. Why is this thread in Altcoin Discussion. I think it should be moved to Bitcoin Discussion. It doesnt have to do anything with altcoins.
Im not a fan of Bitcoin XT, its not why i write this, the simply risks of "our" coin becoming the coin of a company is not for me. Though i think this discussion should be discussed in the correct place.
Altcoin Discussion is the proper place to discuss XT. Theymos is very generous to make such an allowance on his private server.
If I were him, XT and Gavinistas would be given the Bitcoin-scrypt treatment (IE disappeared like pinkos in Pinochet's Chile).
The logic is simple enough:
Activating a hardfork based on what miners do is really bad. You could easily have a situation where 75% of miners support XT but none of the big Bitcoin exchanges or businesses do. Then miners would start mining coins that they couldn't spend anywhere useful, and SPV users would find that they can't transact with the businesses they want to deal with. The currency would be split, and in this case XT would be in a far weaker position than Bitcoin.
The possibility of this sort of network/currency split is what makes XT not a "legitimate hardfork", but rather the programmed creation of an altcoin. A consensus hardfork can only go forward once it has been determined that it's nearly impossible for the Bitcoin economy to split in any significant way. Not every Bitcoin user on Earth has to agree, but enough that there won't be a noticeable split.

I know what you mean and i agree to a certain degree. For now i see the chance that bitcoin xt MIGHT become the real bitcoin. I doubt it but the chance is there. Then it would not be correct to discuss bitcoin xt in altcoin. Bitcoin xt should be discussed as bitcoin until it shows that it is an altcoin only. I mean when bitcoin core is forking then it is not the original bitcoin anymore too. And we don't switch to altcoin section then too.
In fact theymos really wanted to do it that way. See my question and his answers:
