So… okay. I will freely admit to being a Blockchain Skeptic™… but not even I would’ve predicted a 0.00% success rate in a survey of blockchain technologies. Yikes.1

Note also that this is specifically blockchain, not cryptocurrency, which is an implementation of blockchain. And even the most diehard crypto-detractor (i.e. yours truly) would probably have to concede cryptocurrencies are “successful”, for a given definition thereof, so I assume they were specifically excluded from the above-linked survey.

  1. But also: lol. []
