Re: Blockchains have no use that could not be better served by a database.
The old adage about hammers and nails rings true.
What the databasistas miss, is not the database functionality of blockchain. It's the fact that it's not intrinsically owned by any individual actor. Which has nothing to do with being distributed.
However, in any discussion of more than 3 people, the meaning of "intrinsic" and "inherent" slowly fade to nothing and people haven't a fucking clue what they are talking about.
Once you remove the requirement "had to make a fucktonne of money" from the blockchain specification, it has it's uses.
The fundamental issue(s) are trust and how we create and use it. Fundamental because the history of trust predates the history of writing.
