Proof of Life
Verify a proof
A .pol file is a signed claim: this person's key signed exactly this audio, and — if witnessed — it existed by a certain date. This page checks that claim on your machine. It says who signed and when; it never claims to know how the music was made.
The server's record
Not a file checkNothing leaves this page. The file is unzipped, hashed and signature-checked with your browser’s own crypto. The only things sent to Epirus are a public key and an audio fingerprint, to ask whether it knows them — never the audio, never the file.
