The idea was that traits of blockchain technology—such as having no central point of failure, being uncensorable, cutting out intermediaries, and being immutable—could also benefit other applications besides money. Financial instruments like stocks and bonds, and commodities like gold, were the obvious targets, but people were also talking about putting other representations of value like property deeds and medical records on the blockchain, too. Those efforts—admirable considering Bitcoin hadn’t, and still hasn’t, been adopted widely as currency—were known as Bitcoin 2.0.
