What stands out to me is how this could give users more control while still following the rules. You don't have to verify the same data over and over again; you can use it again.
The use case for cross-border transactions is also interesting to me. Today, it takes a long time to make international payments because systems need to learn to trust each other again.
With portable attestations, that layer of trust could already be there, which would make things go more smoothly and quickly.
Another thing to think about is privacy. Users don't want to share everything, but governments need to keep an eye on things.
Attestations only let you share the information you need to, not all of your personal information. If CBDCs are going to be widely accepted, that balance is important.
From what I've seen, the industry is slowly moving toward modular systems, which handle identity, payments, and data separately but keep them linked. The fits@SignOfficial right in with this direction.
If CBDCs become the norm around the world, the real question won't just be who issues them; it'll also be how trust is handled behind the scenes.
And to be honest, that's where Sign Protocol could have a much bigger impact than most people think.
