I used to think crypto data was basically untouchable. Like once it’s there that’s it. Forever.
Turns out, that’s kind of a problem.
I was digging into Sign and noticed something I didn’t expect they actually let proofs be revoked.
So if something changes, like someone loses access or fails a check, the old proof isn’t just sitting there being wrong it can be tossed out or replaced.
And yeah, that sounds simple, but most systems don’t do this. They just keep stacking outdated info and pretend it’s still valid.
Which honestly makes no sense.
What I like here is it feels more… real. Stuff changes. Rules change. People change.
So the system changes too.
Not just store it and forget it,
but more like store it, check it, and fix it when needed. Way more usable, if you ask me.
