Proof without exposure.
Every important agreement eventually becomes a question. NightSign answers it — without exposing the document behind it.
Signing should come with a receipt.
The whole record stays private. Only the proof comes out.
NightSign doesn’t publish the interview, the answers, or the attachments. It records the fingerprint and the few facts anyone needs to verify — nothing else leaves the room.

DAY · WHERE READING AND SIGNING HAPPEN
Ink on paper. Like it always was.
Signatures started as black ink on white paper — clear terms, plain sight, no clutter. NightSign keeps the paper and upgrades the proof. Anywhere you read or commit, the surface is paper. The dark is reserved for what we show you, never for what you must read.
No box dragging
Packets declare what must be acknowledged. Senders never place signature fields; signers never hunt for them. The document is the interface.
Receipts that tell the truth
Every receipt states exactly what it proves — and just as clearly, what it doesn't. No inflated claims, no fine-print surprises.
Verify in seconds
Paste a receipt ID or hash. No account, no upload of private content. Anyone you hand a receipt to can check it.
Today
Built for today's workflows.
Organizations already need to prove who acknowledged what. NightSign produces independently verifiable receipts while keeping the underlying documents private.
Tomorrow
Ready for tomorrow's workflows.
The same receipt model can extend naturally to automated and agent-driven systems as organizations adopt AI-assisted workflows.
NIGHT · WHERE PRIVACY LIVES
Midnight inside.
A lets you prove a fact without exposing the document behind it. What you choose to disclose steps into the light. Everything else stays in the dark — provable, but private. That is the layer NightSign is building on the Midnight Network — demo-proven on a standalone Midnight network, with production anchoring our next chapter.
- Prove an agreement was signed without revealing its contents
- Disclose single facts — a date, a version, a party — not the whole record
- Selective disclosure enforced by cryptography, not by policy promises
AGREEMENT · PRIVATE RECORD
ROADMAP CONCEPT — ZK SELECTIVE DISCLOSURE ON MIDNIGHT
Your next agreement, in black and white.
Quick to send. Effortless to sign. Provable for as long as you keep the receipt.
V0 BOUNDARY — this demo proves local packet acknowledgment and receipt verification. It does not yet prove legal identity, notarization, wallet ownership, persistence, or Midnight anchoring.
