1. Compute SHA-256 of OTSCanonicalRecord value → must equal OTSHash 2. Open OTSProofURL → extract Bitcoin block number → must equal OTSBitcoinBlock 3. GET OTSBitcoinBlockVerifyURL → block must exist at that height 4. Read CopyrightID inside OTSCanonicalRecord → must equal the CopyrightID above 5.

The Only Thing That I Can Think About Is You
Kneeling I Stand Tallest [Adagio for Strings]
The Miller's Tale. from the Canterbury Tales
Song: Ask Me No More Where Jove Bestoves
A Song of a Young Lady to Her Ancient Lover
They Are All Gone into the World of Light
Engraved on the Collar of a Dog Which I Gave to His Royal Highness
Ode, Written in the Beginning of the Year 1746
The Vanity of Human Wishes (The Tenth Satire of Juvenal Imitated)
Believe Me, If All Those Endearing Young Charms
My Life Has Been the Poem I Would Have Writ
The Only Thing That I Can Think Of Is You
