PROOF OF LIVE PERFORMANCE · DUBLIN · ARTICLE 50 ENFORCEABLE IN 58 DAYS

The law makes you
label the fake.
Teist proves the real.

From 2 August 2026, synthetic audio and video must be labelled in the EU. But a label is opt-in for the honest, and the tools used to clone an artist do not volunteer one. Teist supplies the other half of the regime: live performance signed at the moment of capture, bound to the performer on stage, and verifiable by anyone.

You can label the fake. Nothing proves the real.

Generative audio has made a cloned voice indistinguishable from the real one. The first convincingly faked live performance will move broadcast and rights-body defaults from genuine-until-doubted to doubted-until-proven, the way the first deepfakes did for photographs.

Detection loses that arms race on principle: it argues with the fake after the fact. Provenance wins by arriving first. The moment of capture is the one place the truth is cheap, and it is exactly where nobody is standing.

Signed where the sound is born.

  1. 01

    Signed at source

    A capture unit signs the live feed segment by segment as it happens, into open C2PA content credentials. Change one byte, anywhere, ever, and the signature breaks.

  2. 02

    Bound to the performer

    Each segment carries proof that the enrolled performer was present and live at the moment it was captured. Not stitched together afterwards. There, then.

  3. 03

    Verifiable by anyone

    A registry and a public verifier return one answer about any segment: verified live, or not. A broadcaster can check it. A rights body can check it. A fan can check it.

The live demonstration runs on real hardware: one genuine capture passing, then a sequence of attacks failing in front of you. Ask to see it.

One deployment, a ladder of proof.

RUNG 01

Signed feed

A tamper-evident record of exactly what came off the desk, when and where. Provenance without enrolment, and already more than a master tape can say.

RUNG 02 · TODAY

Presence-bound

The signed feed, plus proof that the named, enrolled performer was physically present and live at capture. This is what the working system proves.

VERIFIED LIVE · presence

RUNG 03 · IN DEVELOPMENT

Performance-bound

The strongest claim: the performance came from that performer, not playback in the room. Built instrument class by instrument class, honestly.

Every verdict names its rung. A presence credential claims presence and nothing more; stronger claims ship only when the system can prove them.

Anyone who pays a price when "live" turns out to be a lie.

Broadcasters air live music with source-level proof behind it, and give the verification desk an instrument instead of a hunch.

Estates and artists certify the genuine catalogue and make impersonations provably uncredentialed.
