two different parts due to differences that I did not know much about. The branching of Steem into Hive is the beginning of the same thing, as is the case with Terra Luna and Luna Classic.

The reason behind hard fork of steem and hive is integration of Tron with steemit which was perceived as an attempt to disrupt the decentralized functioning of the steemit by some of the witnesses of steemit.

LUNA and LUNC hardwork resulted from the crash of LUNA following some Technical glitch in algorithm.

Good luck
