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 Note: an OTS proof may carry multiple Bitcoin attestations; OTSBitcoinBlock is the earliest confirmed one — a later attestation inside the proof corroborates it and is not a mismatch
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
There is a deeper implication to all this
You are the fundamental force of my life
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
There's a part of me that no one ever sees
You are the only one, the only one for me
How did you know that I was the one for you
When I first saw you I knew you were the one
You are the one that I've been looking for
Will Christmas Ever Be the Same (vintage)
It's Finally Christmas Time (romantic Christmas song)
Dear Santa I've been good all year (vintage)
When It's You and Me Under the Christmas Tree
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 Note: an OTS proof may carry multiple Bitcoin attestations; OTSBitcoinBlock is the earliest confirmed one — a later attestation inside the proof corroborates it and is not a mismatch
