All we know Chinese Miners have total 56% mining power[1] publicly. (There's 26% that we don't know who have it).
What if Chinese government decides to cut their internet connection from outside of the world? (You know such thing can be done, eg: north korea [2]) Or maybe an earthquake can cut their internet from backbone (maybe not all of it but most of it).
And as result of these scenarios ~50% of miners in China will still mine bitcoins in a local internet like a huge LAN. And rest of the world will mine in another bigger LAN but there'll be no connection between them.  Of course there'll be 2 different major forks.

After 1 month everything went normal. So there're 2 major forks of bitcoin network. How will we decide? Which one is legit chain? Both of them looks legit.

Possible solutions:
- Major mining farms should use secondary internet connection such as satellite connection. Which can be blocked by governments. But it's not affected (or minimally affected) by natural catastrophes.
That's why I support jgarzik's "bitcoin satellite project" [3]. Even if governments ban satellite connections which is provided by gov controlled ISP's; Personal satellite internet dishes can connect bitcoin satellites. There's a catch here, jgarzik's satellites will provide only blockchain (to distribute accepted blocks) they're not gonna be used for broadcasting block candidates.

No worries.

If this situation were to arise, I think the lead devs (Hearn and Gavin) would just release an emergency patch to get everyone back on the "right" fork!

PLEASE don't post that "china can't/won't ban/cut off internet connection".

That's what I worry about: "right" fork
Let's say 4% of unknown 26% HR coming from China. That means china has 60% of network and rest of the world has 40%.
How will Hearn and Gavin decide which one is "right" fork?

If bitcoin is controlled by a few programmers or a group of mining farms, then it is even worse than 12 FOMC members in FED. Bitcoin should be easy to understand for everyone, no conspiracy and hidden secrets. No one in the world can use personal power to affect gold's property, so should bitcoin. Gavin is just following the early hints of Satoshi, nothing more

Bitcoin is actually quite simple.  It can and should be understood fairly well on several different discipline levels by anyone who chooses to putter around with it.

I find it interesting that of the core developers only a few seem confident to state with full assurance exactly what Satoshi would be thinking and doing at this phase in the game.  Many people (myself included) have had various philosophical shifts in certain areas and made some adjustments as things have evolved over the last few years and assume that anyone, Satoshi(s) included, could have done likewise.

I can think of at least three hypothesis why someone might state with assurance exactly what Satoshi would do.

 1)  They are in contact with him.

 2) They somehow know he no longer walks among the living and won't be back to clown them.

 3) They are desperate and it's worth the risk of an in-person clowning to further a goal.

The big mining corporations and pools are most probably constantly in contact with eachother to make sure something like this doesnt impact their revenue. Its a big gamble for both sides to just stubbornly mine both chains.

The Great Firewall of China could disconnect Bitcoin easily. All they have to do is block the seed hosts, block port 8333, and recognize Bitcoin connections inside of unencrypted TCP connections.  A few rules in the firewall is all it would take.

so this would leat to two legit fork that would remain operative like they are two big nodes that work separately, so nothing will happen in the end, from china, miners can still sell their coin on exchange, because they will be accepted

the only problem would be that the network, would issue two full block and two full reward...

so a total of 42M coin would exist in the end

one thing is that the china fork, could dump only on their exchange, so it's like they have created their own china bitcoin(but with the same bitcoin price), and we can still dump on the normal bitcoin, so the more legit fork should still be our fork...


the problem is that there is no connection, thus two 100% legit chains will be created, and miners can dump their coins from any of those chains, not to mention that they will mine two full block, and when you reconecct, what coins will be orphaned?

Why would China do such things? If they control major operations in Bitcoin, any disturbance like separate blockchains, 51% attack etc would only damage the price and development. That is against interests of a major power like China.
