Noxen: Reveal less.Verify more.
Noxen is a selective disclosure tool on Robinhood Chain. Split a document into fields in your browser, anchor one Merkle root of salted hashes with your wallet, then hand out a single field with a proof anyone can check. The rest of the file stays with you.
What people provewithout showing the rest.
Six everyday disclosures. Each field is checked against a root on Robinhood Chain; every other field in the document stays a salted hash.
Confirm the degree, skip the transcript
proof › Degree title and graduation year are disclosed. Grades and the student number never leave the sender's browser.
Match the total, hide the client list
proof › A buyer checks the invoice total against the anchored root. Line items, rates and client names remain sealed.
Tell a landlord the start date, nothing more
proof › One line from the contract, one short proof. The landlord learns the date and that it came from a document anchored earlier.
Show that this draft existed on a date
proof › The root carries a block timestamp. Disclose a paragraph months later and anyone can confirm it was part of that root from day one.
Pull back a record that went stale
proof › Only the wallet that anchored a root can mark it revoked. From that block on, every verifier sees the revoked status.

Sending the file overshares.One field is enough.
The full upload is the sheet on top. Drag it aside to read what a selective disclosure sends in its place.
Q.01Prove your employer to a lender
One field + proof
employer: Northwind Works. Plus three hashes that tie it to a root your wallet anchored. Nothing else travels.
Whole file
The whole contract PDF: your name, home address, salary, ID number, bank details and signature, forwarded to whoever asks next.

Redact. Anchor.Prove it.
Redact
Type fields or paste a document as lines. Choose what to show; everything else becomes a black bar and a salted hash. It all runs in your browser.

Anyone with a disclosure package can check it: the field hashes up to the root, and the root is active under the address they expect.

What this site does not do with your document
We never see the file.We never store the file.We never hold your keys.
Hashing runs in your browser. The chain receives a 32-byte root, which is public, permanent and linked to the address that sent it. That is not anonymity and not encrypted storage.Read the label
