Most people I talk to still treat Sign Protocol like it’s just a simple attestation list. That’s way too basic. Honestly, that’s missing the point.
Here’s the thing It works more like a reusable trust pass. You check something once, and instead of moving raw data everywhere, you just carry a signed proof others can rely on. Simple idea. Big impact.
Now look at cross-chain setups. They’re messy. Always out of sync. Checks repeat. Stuff breaks. I’ve seen this before. Sign helps by letting different apps use the same verified claims without rechecking everything again and again.
But yeah, this is where things get tricky. Who decides which issuers you can trust? And what happens when those proofs get old or wrong? People don’t talk about this enough.
That’s the trade-off. Clean trust on one side. Risk on the other.
