1. Compute SHA-256 of OTSCanonicalRecord value → must equal OTSHash 2. Open OTSProofURL → extract Bitcoin block number → must equal OTSBitcoinBlock 3. GET OTSBitcoinBlockVerifyURL → returns the Bitcoin block hash at height OTSBitcoinBlock; GET https://blockstream.info/api/block/{that hash} → its timestamp must match OTSTimestamp 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
Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0xd1c8dde7da43db91477be4eb4764582bcf880bfa8d80d43857cd47ae40927a82. Chain 2 (Bitcoin): anchored in block 953907 (2026-06-16T07:39:24Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Do you wake up in the middle of the night
I want to cook something special for you
You are the fundamental force of my life
There is a deeper implication to all this
Are you ready for the love that I have for you?
There's always one reason to live (Live)
You're more than just a face in the crowd
You're the one who loves me in plain sight
When you are ready, I'll be waiting for you
I will never forget you, you're always in my heart
You are the only one, the only one for me
There's a part of me that no one ever sees
How did you know that I was the one for you
You are the one that I've been looking for
When I first saw you I knew you were the one
Will Christmas Ever Be the Same (vintage)
It's Finally Christmas Time (romantic Christmas song)
Dear Santa I've been good all year (vintage)
I Long for Christmas When You're in Town
1. Confirm isrcCode identifies the recording in the pre-2022 source corpus and cc-db-prod record 2. GET OTSVerificationAPI → server-side canonical-record, hash, and attestation checks must pass 3. GET OTSBitcoinBlockVerifyURL → returns the Bitcoin block hash at height OTSBitcoinBlock; GET https://blockstream.info/api/block/{that hash} → its timestamp must match OTSTimestamp 4. Confirm CopyrightID is the CopyrightChains transaction hash 5. If all match: the cc-db-prod record is independently anchored on Bitcoin at OTSTimestamp
