The hardest question in AI music isn't "is it good?" It's "who made it?"
When a track blows up, that question gets asked with money on the line. When a track gets ripped and re-uploaded by someone else, it gets asked with your name on the line. And "I have the original file on my laptop" is a weak answer — files copy perfectly, and timestamps on your own hard drive prove nothing to anyone else.
An Authorship Record is Cambrian's answer: a timestamped, cryptographically signed statement of your creative role in a track, published where anyone can check it.
What's actually in one
When you create a record, you document the human side of the work: how the track was made, which tools you used, your prompts and process, the source files that matter. Cambrian then:
- Computes SHA-256 hashes of your evidence files — a fingerprint that changes if even one byte of a file changes
- Assembles everything into a canonical record with a timestamp
- Signs it with ECDSA (P-256) — a cryptographic signature that can't be forged without Cambrian's private key
- Publishes the certificate on a public verification page
The result: a public page showing the record hash, the signature, the evidence manifest, and the public key needed to check it all.
The part that matters: anyone can verify it
Verification doesn't require trusting us or logging in. Every record gets a public URL — cambrianmusic.com/verify/your-record-id — where the full certificate is visible: the canonical record, its hash, the signature, and the signing key.
A skeptic can independently confirm that the record existed at the stated time, that the signature is valid, and that the evidence hashes match the files you claim. If someone re-uploads your track next month and claims it's theirs, you point at a signed, dated record they can't replicate.
What it honestly is — and isn't
We're careful about this, because overclaiming is how you get dismissed.
An Authorship Record is a signed, timestamped, publicly verifiable statement of the creative contribution you documented — evidence that's meaningfully harder to fake than a file on a hard drive.
It is not a copyright registration, and it isn't legal advice. Copyright in AI-assisted work is a moving target across jurisdictions, and what's protectable generally tracks the *human* contribution — which is exactly why the record focuses on documenting yours: the prompting, curation, arrangement, and editing that made the track yours.
What it costs and where it shows
A record is a one-time $10 per release. Once issued, your track page carries a verified badge that links straight to the public certificate — so listeners, collaborators, and anyone doing diligence can check it in one click.
Why this exists
In a world where anyone can generate audio, the scarce thing isn't output — it's accountable authorship. The creators who'll be taken seriously long-term are the ones who can show their work.
That's a bet on transparency, and it's the same bet the whole platform makes: say how it was made, stand behind it, and let the music be judged from there.
Create a record for your track — upload first, then start the authorship flow from your studio.
