Storing everything on-chain sounds cool… until you see the gas fees and latency.
That’s the bottleneck most projects quietly run into.
Sign Protocol doesn’t force that trade-off. You don’t have to choose between “secure but slow” or “fast but fragile.”
You put critical stuff on-chain. The things that actually need to be immutable. Proofs, approvals, key records.
Everything else? Off-chain. Cheap. Scalable. Still verifiable.
Think about it like this:
store the fingerprint on-chain, not the whole file.
So your app stays fast. Users don’t get wrecked on fees.
And you still keep the trust layer intact.
This is the kind of design that actually works in production. Not just in whitepapers.
