user19411: Is it possible to change rules of mining bitcoin division?

rewrite P2P bitcoin client (or write maleware) which will be pretending that fake bitcoin client is legal, original client 
distribute program more/less widely
then by fake client division of mining loot will be with fake/own rules (e.g. give more bitcoins to farm X, even if farm X didn't work more than others)



no changing keys
no faking difficulty level/spent time
maybe changing proof-of-work action


user12983: Yes, it is possible.
This is "hard-fork" (bitcoin with other rules) or "alt-coin" (any crypto-currency with its own rules)

user5292: No. Your question is very hard to make sense but whatever any fake node does still requires the Proof Of Work which cannot be faked. Anything the fake node does (with or without proof of work) that's not according to the consensus rules will be rejected by other nodes. From that moment on the fake node is not dealing with bitcoin anymore no matter how hard it tries to put that label on it.
