Signal
A radio play, like or playlist provenance event is recorded.
Nothing in the signal goes unnoticed
The song ends. The proof remains.
If a song plays but no one can prove it, what value survives the moment? APR Signal Ledger makes sure recorded airplay never disappears into silence. Every sealed play leaves a verifiable trace tied to the track, its playlist provenance and the human response.

The song ends. The proof remains.
Search for a track above. When it exists in a sealed daily batch, APR shows that the moment truly happened — with plays, playlist provenance, likes and cryptographic inclusion.
From airplay to proof
One signal. Five layers.
The ledger works beside the audio chain and never alters the music. It records the public events the radio already creates.
Hash
The event is normalized and cryptographically linked to history.
Merkle
The day's signals are sealed beneath one verifiable root.
EAS · Base
The batch becomes EAS-signed for Base when a valid signature exists. A transaction appears only after real onchain timestamping.
Verify
Anyone can check a track's inclusion in the public proof.
Proof without surveillance
Transparency. Not surveillance.
We publish what creates checkable music value and keep personal information outside the ledger.
What gets proved
- Spotify track, artist and playlist provenance
- Aggregate radio plays and likes
- Timestamps, batch root and Merkle inclusion
- EAS signature and Base transaction when it exists
What never gets published
- Emails, IP addresses or sessions
- Full pitch copy or contact details
- Individual voter identities
- Internal editorial notes or payment data
Why proof matters
Nothing meaningful passes unnoticed.
A radio play is a moment. Proof of Airplay makes that moment portable, checkable and useful long after the music fades.
Provable exposure
The track moves on. A shareable certificate lets the proof travel with the artist.
Traceable provenance
The path from human curation to radio play does not vanish when the broadcast moves on.
A signal worth trusting
Real reactions become transparent foundations without exposing listener identities.
Token-ready foundation
Built for the next layer.
APR Signal Ledger creates a verifiable foundation a future APR token could interact with: proven activity, public certificates and transparent network data. The token is a future possibility — not a launched product or a promise of returns.
Non-negotiable principleNo token, payment or wallet can rewrite verified proof or buy an editorial decision.
