    To clarify further, a blockchain requires some kind of distributed consensus. If you have two versions of the same blockchain, there must be a way to figure out which one of these is the one everybody else is following. In Bitcoin this is achieved with proof of work (i.e the version of the chain that has wasted most electricity).

    If you don’t have distributed consensus, then you just have a git repo.
