How do you make a piece of data provable, portable, and still usable across completely different systems?
At the center of it is this idea of attestations. Basically, you’re making a claim structured, signed, verifiable.
That’s it!
But the way SIGN handle storage is where it gets practical. You can throw the full data on-chain if you care about maximum trust. Expensive, but clean. Or you just anchor a hash and keep the actual payload off-chain. Way cheaper. Or mix both depending on what you’re doing.
Schemas tie it together.
They’re just templates, but portable ones. Like, everyone agrees on the shape of the data first, then you can move that logic across chains without rewriting everything
That alone saves so much pain. I’ve rebuilt the same validation logic across different environments more times than I want to admit.
And yeah, Sign is using asymmetric crypto and zero-knowledge proofs under the hood
So instead of exposing raw data, you’re proving properties about it. I’m over 18 without showing your ID.
SignScan is in there too. It’s basically an explorer for all this. One place to query attestations across chains. Honestly, this is one of those why didn’t this exist already? things.
Instead of building custom indexers or juggling APIs, you just hit one layer.
But the part I keep coming back to the one that’s kind of living rent-free in my head is the cross-chain verification setup with Lit Protocol and TEEs.
Because this is usually where everything falls apart.
Bridges are messy. Oracles are messy. Anything that tries to move “truth” between chains ends up either too centralized or too fragile. And Sign’s approach is different enough that I had to read it twice.
So here’s how I understand it.
You’ve got these TEE nodes trusted execution environments. Think of them like sealed boxes. Code runs inside, and you trust the output because the box itself is locked down. Now instead of one bo
