SIGN sounds like the kind of idea that makes perfect sense at first glance clean, efficient, almost inevitable. A system where credentials can be verified anywhere and tokens move without friction. But the more you think about it, the more it starts to feel less like a tech problem and more like a human one.
Because “verifiable” sounds good… until it also means “always visible.” Not everything about a person or an action is meant to live forever in a system that never forgets. There’s comfort in being able to prove things when needed, but there’s also value in not being constantly defined by a permanent record.
Same with accountability. In theory, tying identity to actions should create more trust. In reality, it can also create pressure, rigidity a kind of system where there’s less room to change, to fail quietly, to grow. Real life is messy, but systems like this tend to prefer things neat and fixed.
And then there’s the part people don’t talk about enough agreement. For something like SIGN to really work, a lot of different players need to align on what counts as “truth.” Not just technically, but socially and politically. That’s usually where things get complicated, or watered down.
It’s not that the idea is flawed. It’s that it assumes a world that’s a bit more aligned, a bit more ready than we actually are. And maybe that’s the real test not whether the tech works, but whether people are willing to live with what it brings.
