Someone say yes. someone say no. Could anyone explain that fork has been occurred or not?
the fork has been done so bitcoin cash already created from that fork
that is an altcoin, not a fork, the fork didn't happen theymos said so in his thread, bitcoin cash is an attempt to do a fork but they created an altcoin, but i don't know why they both share the same private key
Same chain, just different miners and thus different nodes. I don't know yet how the network differentiates between the different nodes. But if it isn't able to, BTC and BCH nodes get a lot of transactions that are invalid. So not only do BCH miners have to sort through a lot of invalid transactions, they have to do this with not a lot of hash.
Not unusual for this to get stuck for a very long time. We shall see.
