I used to think digital signatures in crypto were limited to one thing authorizing transactions. It felt narrow and, honestly, a bit disconnected from how businesses actually operate.
Then I came across Sign, and it shifted my perspective.
What stood out is that signing is not restricted to payments. It can be applied to any kind of data agreements, approvals, records and those signatures remain verifiable over time, even across different chains. That changes the role of signatures from a transactional tool to something more foundational.
The problem is simple: most digital systems still rely on fragmented records and repeated verification.
The solution here is equally simple: turn signatures into reusable, verifiable data objects.
