Look, people keep trying to box Sign in as just an identity tool, and honestly that’s way too narrow. I’ve seen this pattern before something starts small and everyone misses where it’s actually going.
Here’s the thing. It feels more like an evidence layer than anything else, especially once regulators start paying attention. Systems don’t get to run on vibes anymore. They need proof. Real trails. Something tied to an issuer you can point at.
And yeah, apps won’t keep hoarding raw data. Why would they? They’ll just reference signed data and move on. Cleaner. Reusable across chains.
That’s where it gets interesting. Accountability stops being optional. It becomes the whole game.
Weird part is people still think this is niche. It’s not at all.
