I do deny that they open up any opportunities. Even if they might do things better (which I don't see that happening; solutions are objectively slower and more cumbersome than centralized databases with audit logging), they appear to solve "problems" that aren't really problems. There's a lot of things that classify as annoyances and inconveniences in the world. That doesn't mean that I'm willing to dump a boatload of cash to solve them. Identity isn't currently a technological issue. Microtransactions aren't a technological issue solved by blockchains. Ledgers of most things in general don't have a trust issue that's solved by blockchains. Technies being techies think that technology solves a lot of issues just by existing while completely discounting the issues of trust and control in institutions themselves. Most blockchain problems are actually governance issues.
