The longest proof of work chain is the consensus mechanism.  

You keep spreading this falsehood. While it is not exactly wrong, it's not perfectly right either.


Not really. "the longest chain" is ambiguous. It should really be "the longest valid chain", and then you need to define which coin's concept of "validity" you're using. Every client follows the longest valid chain - that's precisely how they decide which chain to follow.

So assuming the question is "will my node follow the longest valid Bitcoin chain?", then the answer is "no" for XT once BIP101 is activated. At that point XT stops following the longest valid Bitcoin chain and starts following the longest valid XT chain, whereas the answer is "yes" for Bitcoin.




It's my understanding that neither of these assertions is true in Bitcoin XT.  XT changes the consensus mechanism significantly:

Another less cited new feature of the XT client is a change to chain selection/consensus rules. XT clients don't follow the longest chain, they follow the chain with the highest XT checkpoint embedded into it.



Exactly what is a checkpoint and how is it embedded in the blockchain?

How does the XT wallet decide which chain to embed a checkpoint into, and how does it decide what height to embed a checkpoint at?

How does the XT wallet decide the frequency and time to embed checkpoints at?

There is only one thing you really need to know: checkpoint is not Bitcoin.

Checkpoint is an attempt a rewriting history. One of Hearn's favorite tool.

Pay no attention to the frog on the right, it just wants to get larger blocks for more tx/s.



then they both fall.  Embarrassed

If I understand correctly, Bitcoin XT has not actually changed this yet - but will do so, if necessary, to 'work around' recalcitrant miners that don't mine the 'right' blocks.

you guys dont friggin get it.

THERE IS NO CHOICE

THIS IS BITCOIN, YOU EITHER LIKE IT OR QUIT IT

THIS IS NOT A DEMOCRACY WHERE YOU CAN CHOOSE WHICH DEGENERATED BITCOIN TURD YOU LIKE

GOD DAMN YOU BLIND SHEEPS ALWAYS CRAVING TO FOLLOW SOME EGOMANIAC DEVELOPER/COMPANY OVER REDDIT

YOU BUNCH OF RETARDS THAT JUST CANT STAND MORE THAN 3 MINS WITHOUT MISSING THE LEASH

I understand that you worry about your investment, but this is not healthy. Either get out of Bitcoin or show some dignity.

Edit:

You're not you when you're hungry.  Maybe you need a Snickers?

Yeah, and that.

There should be more than one implementation of the bitcoin protocol.
Also, there might be legitimate use cases for "enterprise" style full nodes etc.
I could think of a thousand reasons why XT could be useful, but the most important ones will likely be the ones I can't imagine right now.

Exactly.  What is wrong with the goal of decentralizing development across multiple competing implementations?


what is LTC? if not a competing implementation.

what we really need is to somehow continue to improve bitcoin in the best possible way.

if we stand still a competing implementation WILL FOR SURE eventually becoming bigger and better then bitcoin.
