  Eachofthesesolutionsalreadyexists,alongwithscoresofothers.Despitewidespreadexperimentation,however,blockchainisstillyoungandevolving.Today’sexperimentsoftenuseonlysomeofthecoreelementsthatmakeablockchain,whilerejectingothers.Inparticular,today’sblockchainsrarelyincludetokens,andtheirtechnologyarchitectureisalmostneverdecentralized,aswasintendedintheoriginalblockchaindesign.Whatthatmeansinpracticeisthatmanyblockchainsolutionsavailabletodayareownedandgovernedbyasinglecompanyorsmallgroup,andonlyauthorizedparticipantscanjoin.(TheBitcoinblockchain,incontrast,hasnosingleowner,andanyonewhowantstocanparticipate.)
