How it works

Your file gets a fingerprint. The fingerprint — never the audio — is written into Bitcoin. Free, forever.

No coin, no wallet. Bitcoin here is only a clock no one can wind back.

You get a public certificate and a badge. Anyone can check them in seconds.

Heard a copy? Paste the link here. We compare it to your track and save the result.

Your signature, worn in public.

One line of HTML for your release page or store. It links to your certificate — anyone can check it, no one can revoke it.

Machines can imitate the sound.
They cannot sign for it.

A named artist stood behind this work, on this date. Anyone can check. Like blue ink on paper.

Platforms guard their walls.
Not your work.

Takedowns can be dodged. Your certificate lives outside any platform — anyone can check it, no one can erase it.

Your file sits in encrypted private storage. Only the fingerprint is public. No one hears it, shares it, or trains on it.

We listen for your work where you are not looking.

Monitoring is coming. Eight dollars a month when it launches. Signing and checking stay free, always.

Claims over trained-on music are already in court. When the settlement comes, your ledger is already there.
