PROOF OF REAL PERFORMANCE

A performance should mean a person was there.

There are already tracks everywhere carrying voices that were never sung, by people who were never in the room. Teist seals a recording to the human who actually made it, as it is recorded, so the real thing can prove itself and the fake cannot.

THE VERIFIER READOUT, ILLUSTRATED

Cloning got cheap. Doubt got expensive.

A convincing clone of a voice now costs about as much as a coffee and ten minutes of reference audio. The first fake that truly fools people, a track passed off as the real thing, will change the rule for every genuine one: from believed until questioned to questioned until proven. Photographs went through that exact door a decade ago and never came back.

Spotting fakes is a losing game, because every detector you build trains the next model to beat it. The law can label the fake, but nothing on the genuine side proves it is genuine. So we stopped arguing with the fake and started proving the real, at the one moment it is cheap to prove: when the sound is made.

  1. 01

    On the performer

    A small device the performer wears signs their motion with a key that never leaves it. It shows a real person was there, moving, as the take was made.

  2. 02

    As it's recorded

    A capture unit seals each segment into an open credential as the take goes down, and binds it to the audio. Change one byte, anywhere, ever, and the seal visibly breaks.

  3. 03

    Anywhere, later

    Anyone can re-run the check and get the same answer. A manager, a platform, or a fan with the file: one verdict, real or not.

It is signed once, at the source. After that anyone can check it, anywhere, for nothing, on an open standard that outlives us and the hardware.

For the people who make it, and the people who look after it.

IF YOU MAKE IT

Your work carries its own proof.

Self-releasing artists, bands and producers. The real take proves itself, and a clone turns up with nothing. Checking it is free, for you and everyone listening.

IF YOU LOOK AFTER IT

Provable as it's built, not fought over later.

Managers, labels and studios. Credential a session the moment it's recorded, so a catalogue carries its evidence from the start instead of arguing for it after the fact.

This is day one, and we mean that.

The proof already works. A worn device, a capture unit, a verifier, the whole chain, running on real hardware. The idea holds and the standard under it is open.

What is left is the real work: turning it into something you would actually reach for in a session, getting it onto records people care about, and growing a registry the whole industry can check against. We would rather build it with the artists and teams it is for than behind closed doors.

NOW

The proof of the real

The full chain runs on real hardware and turns away the fakes we throw at it.

NEXT

Into the session

A plug-in that signs takes as they are recorded, and the first credentialed records with real artists.

LATER

An open registry

A public place anyone can check a recording against, that grows with every credential added.

Checking is free. For ever.

Anyone can verify any recording for nothing, and always will. Only making a credential costs, and only for whoever is in the room. The people who make music, and the people who listen to it, never pay to know it is real.

Before proving it's real becomes the hard part, let's talk.

Teist is early, and that is the point. The cheapest time to put proof of the real in place is before everyone needs it. Whether you make music, look after it, or want to back what we are building, say hello.
