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

Either decisions are made using proof of work or they are not.

Bitcoin consensus does not comes about through proof of work [longest chain]

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

The longest valid chain is determined by the miners according to where they point their hashing power. Miners also choose what code they run and therefore what type of blocks they produce. Therefore the miners can fork the network and create the longest valid chain even if the majority of full nodes choose not to follow such a fork. Essentially both the miners and the full nodes have the free choice to run whatever code they want, however it is the miners that determine which side of the fork will have the longest valid chain.

Therefore when Bitcoin forks in order to increase the blocksize which will most likely happen since the majority of miners do support increasing the blocksize. Small blockists can choose to ignore the longest chain causing the network to split. I respect this freedom of choice even though you have continuously denied it, which might be very ironic if you do end up on the smaller chain.

What you are explaining here is the longest chain, without the word valid. While the longest chain is usually valid, it's not necessarily so. Validity is decided by the nodes which are the economic majority. Miners are incentivized to follow the economic majority, but they are not required to do so.
