Re: What if the fork will split bitcoin blockchain?

it will not split anything, it will simply create a legit chain and a uselesses one that will eventually die, because it has not enough consensus, and will become the altcoin, the other will be again the bitcoin chain we all know

so there is no two chain ever, as a many believe, that is simply wrong on so many level it's not even funny anymore

Amph is right. However, I don't know if will be possible to send bitcoins from one chain to the other one.

I think if you leave your Bitcoins in an address before a fork and don't move them then you could send Bitcoins from one chain to the other one provided both chains used the same nodes. After you had moved your Bitcoins they would only be accepted by one chain, and rejected by the other. If both chains used different nodes then you couldn't send Bitcoins from before the fork from one chain to the other.

Although they use same nodes to be supposed but what about input script they will have, i think those input and output script will be different making it impossible to move bitcoin between two types.

I thought input scripts for coins moved before the fork would be identical so the coins could be moved from one fork to the other. The blockchains for both forks would be identical up to the block where the fork occurred and the blockchain is where the information for the input scripts comes from. Without doubt input scripts for coins moved after the fork would be different so those coins couldn't be moved from one fork to the other.
