Verify a Protected Work

Enter a notice number to see its public record: the work, the claimant, the notice dates, and whether its blockchain proof checks out — looked up live, right now.

What an issued certificate looks like: view the template certificate (PDF). Real certificates carry the author's name, the notice number, dates and the blockchain proof.

Every notice number appears on the work's book page and on the public notices list. The certificate itself is the author's to show and is not published here.
