You know, I was reading about how countries build digital identification SigN. It turns out there are three main models. The first - centralized: everything in one database, convenient for the state, but if it's hacked - the whole country is there. The second - federative: agencies exchange data, but still, a complete picture of your movements and requests is collected somewhere. And the third - wallet-based: data is stored by the individual, and they decide what to share.
And here’s the question: which one will win? And Sign says that none will. Because the country needs all three. Centralized - for control and quick coverage. Federative - to avoid breaking old systems. And wallet-based - so people finally stop handing out copies of their passports to every passerby. And Sign is building exactly what connects them. A layer of trust, where you can confirm age or citizenship without unloading your entire biography.
It seems to me that this is that rare case where technology solves not a technical problem, but a human one. Because now we are used to giving documents for any little thing. But it should be the other way around: you only confirm what is necessary. And that's it.
