[bitcoin-dev] Bitcoin is an experiment. Why don't we have an experimental hardfork?

No, BitcoinXT won't become a Schism hardfork, or may be just for a few 
days, at most.

There is one, and only one scenario that BitcoinXT will win: it is 
supported by major exchanges, merchants, and investors, and they request 
miners to support it. When BIP101 is activated, these exchanges will 
refuse to accept or exchange tokens from the old chain. Miners in the 
old chain can't sell their newly generated coins and can't pay the 
electricity bill. They will soon realize that they are mining fool's 
gold and will be forced to switch to the new chain or sell their ASIC. 
The old chain will be abandoned and has no hope to revive without a 
hardfork to decrease the difficulty. The dust will settle in days if not 

Will the adoption of BitcoinXT lead by miners? No, it won't. Actually, 
Chinese miners who control 60% of the network has already said that they 
would not adopt XT. So they must not be the leader in this revolution. 
Again, miners need to make sure they could sell their bitcoin in a good 
price, and that's not possible without support of exchanges and 

What about that Not-Bitcoin-XT? The creator of the spoof client may stay 
anonymous, but the miners cannot. 95% of the blocks come from known 
entities and they have to be responsible to their actions. And again, 
they have real money in stake. If bitcoin is destroyed, their ASIC 
serves at best as very inefficient heaters.

So Bitcoin-XT is basically in a win-all-or-lose-all position. It all 
relies on one condition: the support of major exchanges, merchants, and 
investors. Their consensus is what really matters. With their consensus, 
that could not be a Schism hardfork. Without their consensus, nothing 
will happen.


Or let me analyse in a different angle. BitcoinXT is in no way similar 
to your examples of Schism hardforks. All of your examples, "ASIC-reset 
hardfork", "Anti-Block-creator hardfork", and "Anti-cabal hardfork", are 
hostile to the current biggest miners and will destroy their investment. 
These miners have no choice but stick to the original protocol so 2 
chains MUST coexist. However, BIP101 has no such effect at all and 
miners may freely switch between the forks. They will always choose the 
most valuable fork, so only one fork will survive.
