Selective proof. Private by default.
VAULTLINE
Reveal the claim. Keep the person sealed.
The Narrow Opening
VAULTLINE lives at the border between a useful fact and an unnecessary biography. A request arrives with one narrow question. The capsule opens one precise line, confirms the chosen attribute, then closes before the rest can follow. Age can pass without a birthday. Membership can pass without a name. Eligibility can pass without a trail. The answer gets through; the life around it does not.
Wish You Weren’t Here
Greetings from the narrow side of the opening. The vault received your entire history, returned one clean yes, and kept the scenery to itself. Nothing unrelated was invited along; the sealed details remained exactly where you left them.
Three Quiet Habits
Three disclosures, each narrower than the record behind it.
Asks Less. Only the requested attribute reaches the opening. Keeps Context. Names, dates, and unrelated details remain behind glass. Closes Cleanly. The proof leaves; the private record does not.
Proof, Not Profile
VAULTLINE separates what must be verified from what never needed to travel. The verifier receives a specific answer; the holder keeps the surrounding record private. It is built for age gates, membership checks, access rules, and other moments where “eligible” is enough and a full identity is excessive. Its shorthand is $VLNE. The requested fact moves. The unrelated facts stay home.
Take only the proof you asked for.
