From the founder · A musician for 30 years
Your work deserves a place in the public record.
Nick Laudani · Founder, SpinStream
Musician for 30 years
“As a musician for 30 years, I believe your creation deserves more than a place in a private administrative record. We’re building a public registry where people can discover the work, see who is making the claim, and inspect the evidence behind it.”
Public visibility. Evidence people can inspect.
A public record gives your creation a place people can find, share and refer to. It brings the work, your recorded contribution and available evidence together—helping you support your claim and protect what you created.
The moment you finalize your claim, we embed your selected evidence layers directly within your artifact. Your public registry record connects others to the work and its available evidence. The written dossier provides an additional way to inspect and keep the evidence.
A public listing supports documentation; it does not by itself determine ownership or guarantee protection.
CREATE IT. STAMP IT. SEAL IT—IN REAL TIME.
Proof details embedded in your artifact. A public record in the registry. Your public written Proof Dossier with Standard or Blockchain.
We don’t just send you PDF evidence.
Your selected evidence is embedded in the actual artifact itself—as you mint it.
The moment you finalize your claim, we embed your selected evidence layers directly within your artifact. Your public registry record connects others to the work and its available evidence.
Go full boat with Blockchain Seal—and add blockchain evidence, too. It’s the only tier with that added layer. Then see your published creation in the OnlyUno Registry, ready to be discovered and its evidence inspected.
The live example above is “Digital artifacts” by Nicholas Laudani. Its built-in seal panel displays recorded identity, timestamp, hashes and blockchain references. The Proof Dossier gives you an additional written record to inspect and keep.
This is a Blockchain example. Evidence depth and available details depend on the selected tier. A recorded claim is not an ownership determination.

Permanent Mark: $4.99 once for your starting record and receipt. Standard: $35 once with the full Proof Dossier. Blockchain: $75 once with the full Proof Dossier plus chain corroboration. Registry inclusion starts with Permanent Mark; the $4.99 credit applies on upgrade.
SpinStream organizes evidence supporting your claim. A seal does not establish ownership by itself or replace copyright registration or permissions.
Ask Little Minty about your rights statement →VIN → AIN · Artifact Identification Number
Your car has a VIN.
Your work gets an AIN.
Think of the AIN like a VIN on a car. It identifies your particular artifact. Its Registry entry gives people somewhere to look it up and check the record behind it.
Your $4.99 brings together a permanent record address, your Artifact Identification Number, a dated Ledger entry, free basic Registry lookup, and a downloadable receipt.
A place you can point to. An identity that stays with the work. A record someone can check.
One work. One record. One AIN.
01 · Mark it
Give it a number of its own.
Your AIN stays connected to the work and its record, including when you upgrade your proof level.
02 · Register it
Give people a way to find it.
Basic Registry lookup is free. Search by artist, title, or AIN to find the public record.
03 · Strengthen it
Add more proof when you want it.
Start with Permanent Mark. Add a deeper evidence package later. Same work. Same AIN.

Nothing becomes permanent until you choose Finalize and continue.
Why give a work an AIN?
Because a filename is not much of an identity.
Digital work can be copied, renamed, reposted, downloaded, and separated from the story of where it came from. SpinStream gives the creator a simple starting point: identify the work and give that identity somewhere to live.
The Ledger records the evidence. The Registry helps people find and check it. The Gallery presents the work. Your AIN connects them, so people can follow the record back to the same artifact.

- Gallery is open for anyone to browse. Creator use and active placement belong to this recurring service.
