If you are gonna downvote, say something.
I can’t tell if you’re downvoting because you saw the word “blockchain”, or you really love it.
I’m using quotes in the title, because I suspect a major amount of people use the word “blockchain” loosely to refer to other related things. If you are willing to, please provide a definition of what you mean by “blockchain” as well.
I mostly hate that people don’t use an article before the term or correctly pluralize it. Saying “we want to use blockchain” is like saying “we want to build house”. You want to use a blockchain/use blockchains/use blockchain technology.
I don’t hate the technology itself. I hate what the applications of the technology have brought us.
