Made it. Mixed it. Mastered it.
Prove it.
Built for working music creators. Provlyn anchors every track, stem, and version to RFC 3161 timestamps and the Bitcoin blockchain — turning your creative timeline into permanent, court-admissible evidence.
The question is rarely "did you write this".
It is "can you prove when". Music creators face authorship disputes more often than almost any other creative profession — and the cases that succeed or fail almost always come down to the same thing: who can prove their version existed first.
Provlyn gives you cryptographic, court-admissible proof of every track, stem, and version — at the exact moment of creation. Not a vague memory. Not a screenshot. Real, verifiable evidence anchored to the Bitcoin blockchain.
What history teaches us
The most-cited authorship disputes in music history have all turned on the same problem — proving when a creative work existed. Industry-changing cases that better proof systems would have settled before they began.
Selle v. Gibb
A songwriter alleged the Bee Gees had copied his unpublished work. The federal jury initially found infringement, but the verdict was overturned on appeal — because the plaintiff could not prove the defendants had ever had access to his song, and he had no record his composition existed when he claimed.
Bright Tunes v. Harrisongs
George Harrison was found to have "subconsciously" copied an earlier song. The court accepted Harrison did not deliberately infringe — but with no records of the independent development of either work, the case dragged on for years and ended in a costly settlement.
Queen / Bowie v. Vanilla Ice
A sampling dispute that became one of the most-cited cases in music history. Settled out of court when no defensible record could be produced of independent musical development. Ended with co-writer credits and royalties paid.
These cases are referenced for educational context only. Provlyn takes no position on the merits of any historical or current dispute.
Built for the way the music industry actually works
From sample disputes to AI claims — proof that stands up.
Sample disputes
When a sample dispute reaches litigation, the case typically turns on access and timing. Timestamp every stem, every loop, every iteration as you create it. Prove your work existed before any contested track.
Sync licensing
When a track is licensed to film, TV, or advertising, the rights chain has to be airtight. Provlyn provides verifiable, court-admissible proof of authorship and version — protecting your sync revenue from claims and clawbacks.
Ghost production
Whether you produce for other artists or hire ghost producers yourself, Provlyn protects both sides of the agreement. Permanent, dated proof of who created what — settling credit and royalty disputes before they happen.
Beat sales and licensing
Every beat sold or licensed should have a permanent record of authorship. When a buyer disputes a license or claims original ownership, you have a Bitcoin-anchored timestamp showing the beat existed in your possession before the sale.
AI-generated content claims
In an industry increasingly flooded with AI-generated tracks, proving human authorship matters more than ever. Provlyn timestamps your creative process — sessions, stems, iterations — establishing a verifiable human creation timeline.
Label and publishing disputes
Establish authorship before signing anything. When a publishing dispute arises — over splits, derivative works, or recapture rights — Provlyn provides cryptographic evidence of what you created and when, independent of any record kept by the label or publisher.
How the proof is built
Two ways to use Provlyn
Music files are big. You decide whether Provlyn just hashes them, or stores them too.
Protect only
Provlyn computes the cryptographic fingerprint in your browser and stores only that. Your file never leaves your device. Best for huge session bundles or material you'd rather not upload.
- ✓ No file size limit
- ✓ No storage charges — uses 0 GB
- ✓ Verify ownership later by re-hashing your file
- ✓ Best for confident professionals with their own backup
Protect & save
Provlyn keeps a copy in your vault as well. Useful for full session bundles, collaboration, and a single source of truth. Each plan includes a storage allowance — overage is tiered.
- Music Pro: 2 GB included
- Music Studio: 10 GB included
- Above included: $4.99–$19.99/month tiered
- Hard cap at 50 GB — above is Provlyn Bespoke
At each annual renewal, your storage tier is recalculated based on the previous month's usage. If you drop back below the base allowance, the overage is removed automatically.

Sometimes you'll have a heavier month than usual. We don't block you — keep depositing. From your next billing cycle, an overage rate applies for as long as your usage stays in that tier. At each renewal, your tier is recalculated based on the previous month's usage.
Above 1,500/mo it is cheaper to upgrade to Music Studio.
At this volume a custom arrangement is usually a better fit.
