Blockchain: the perennial solution in search for a problem.

• j-pb 3y ago
  There are two uses cases that blockchain would solve nicely. Proof of publication in a fully decentralized academic journal, as an alternative to the current grifting scientific publishing industry. As a consensus protocol for a distributed graph database, where you ensure consistency through exclusive ownership of nodes by single writers. But those things don't offer any get rich quick shemes, so we're stuck if crypto bros and pyramid shemes.

  Actually, blockchain will work for generating guaranteed unique identifiers. After all, each bitcoin is different, right?
  • c00lio 3y ago
    Each bitcoin is identified by a block assigning it to a key. Keys are not guaranteed to be unique, with enough guesses you can duplicate one (if you have some time before the heat death of the universe or so) and maybe win the lottery (i.e. access to someone else's bitcoins). So in all, things are more "very probably unique".

    Creating unique identifiers while having access to a global db of all previous unique identifiers is not really the problem uuid is trying to solve most of the time.
