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. GET OTSVerificationAPI → pre-computed 6-check result from server 6. If all match: this entity was registered on CopyrightChains at OTSTimestamp, independently verifiable on Bitcoin

On Dasher, on Dancer, on Prancer and Vixen, on Comet, on Cupid, on Donner and Blitzen
Sing We Now of Christmas Ding Dong Merrily on High
Snow-body I'd rather spend Christmas with
It Must Have Been The Mistletoe Our First Christmas
It's Just Not Christmas If I Can't Spend It With You
may Santa work his magic to the nth degree
The Christmas Song Chestnuts Roasting On An Open Fire
Op U Mijn Heiland Blijf Ik Hopen Kerstmis
L'enfant de la promesse Away in a Manger
Right in the Heart of the Holiday Hustle
Chimney's Welcoming Glow, Home's Calling
Mistletoe, Balance of Giving and Receiving
Horse-Drawn Coaches Bring Scholars Together
Historic Streets Beckon Yuletide Spirits
You Bring the Strawberries, I'll Bring Cheer
Sleigh's Journey Through Time's Tapestry
Wat Ik Wil Met Kerst - ALL I WANT FOR CHRISTMAS IS YOU
