Re: Bitcoin XT - Officially #REKT (also goes for BIP101 fraud)

If the nodes and miners reject a block as invalid then it would not persist as the longest chain. If the nodes and miners accept a block and continue to build on top of it, then that chain is Bitcoin.

Proof-of-work both enforces and defines the laws of the systems

Proof-of-work exists to order transactions deemed valid by the consensus of rules dictated by the nodes.

For the millionth time it's the longest *valid* chain you disingenuous fuck

I agree. Nodes will only accept and miners will only build upon a chain that contains valid blocks. A chain that persists as the longest and continues to be built upon must be valid.

Except that's not true as was evidenced by the July 4th forks in which 5 consecutive invalid blocks were mined on top of each others.

Same is also true for the March 2013 fork.

It was true: miners and nodes abandoned those chains and they did not persist as the longest.

Great, so we agree that miners hold no power over what constitutes the longest valid chain.

Disagree. Miners hold power > 0.
