Is it just me or do the replies I'm seeing come across condescending and unsubstantial? I'm also missing why your PhD in cryptography is any important for the sake of the argument. We are not you in regards to your last remark by the way: "...expect us to nod along". But since you are looking for a good argument to support your confirmation bias, blockchain itself doesn't solve anything. It's just a data structure and a tool. The problem solving happens in the bigger picture, e.g. "decentralised trust management". But let me ask you this: exactly what problem will a database/tree/file solve for vehicles or currencies? We can agree upon that what you are asking and looking for can't be answered or will get a reply similar to: we don't have that problem. You may have asked the wrong question though. Let me be more precise and create a problem that doesn't exist but for programming purposes I want these requirements: many users should be able to read a (hardly) modifiable data structure that gets more resilient the more use it and that is a singleton who everybody has access to (call it decentralised if you will). Blockchain sounds like a perfect fit doesn't it? Now, when we replace the data structure keyword with OS and resiliency with speed, we can agree upon that this sounds like a decentralised operating system (Ethereum or whatnot). Don't get me wrong. I don't see any problems that need to be solved with blockchain right now either. But clearly there is a trend in cryptocurrencies and decentralisation that seems to be important to a lot of people. There are tons of problems that need solving: trust misuse, censorships, privacy issues, advertising and so on. That there is a need for a change is obvious. That this change started with blockchain technology is good. I'm also sure cryptography is important to you too. Why not embrace an emerging technology that benefit your field of study?
