Useful links to debunk fake blockchain use cases

“Blockchain” has dozens of definitions, it’s basically what people want it to be. That’s why you may read articles about “blockchain” solving almost any issue and transforming every single industry. It’s a logical fallacy as “blockchain” is used by many as a synonym of “software leveraging cryptography”, and it’s true that software is eating the world.

In reality, blockchains were designed to solve one specific problem: the double spending of digital cash without relying on a central third party. The only innovation of bitcoin in 2009 is that it gets rid of central authorities. All the other functionalities (append only database, linked lists, peer to peer networking, consensus protocols in distributed environments, merkle trees, public/private cryptographic keys, etc.) are 30-year-old pieces of technology that are used in distributed software in centralized environments.

So it’s obvious that all the use cases involving authorities such as voting, provenance and any case involving a public or private entity do not need a blockchain. Same with any case involving real world assets or products, as a blockchain can only manage native digital tokens.
