The speculation has burned off. Most of what got built is gone or forgotten - the party's over. What's left with us is after-party landscape, sticky floor and the broken bottles. But these sobering moments, once the hangover sets in, are exactly when the questions bite sharp. So it's a good moment to ask: what was blockchain technology for in the first place?
The answer most people reach for is "removing middlemen." But that's an answer to a smaller question. To see what blockchain is really aimed at, you have to go one level deeper - past the intermediaries, past the technical machinery - to the thing underneath both.
The problem
Human nature is unreliable, and it fails us in a specific, repeating way. Give a person power over something shared, and sooner or later they bend it toward their own interest. Not always, not everyone - but reliably enough, across enough people, that you can treat it as a constant.
Let me give you the smallest possible version of it. Years ago, as a student, I was queuing at the post office on our campus to pay a fee for an exam application - exam season, crowded, a bit chaotic. At the door stood a middle-aged security guard whose entire job was to regulate who went in and who goes out. But you could watch it happen in real time. The tiny scrap of authority went to his head. Instead of just doing the procedural thing, he got rude, made people wait, made sure everyone understood he was above them. And my conclusion was that this wasn't his personal problem. It was human nature problem talking through him. Flawed human nature talking through a thousand historical faces, across cultures, historical periods and position of power we've ever invented. It was just same old human nature doing it's thing, nothing more.
