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 0x6cd948fb2812eeda299a4c66eb87327abefbd226db4ba64a20020d65ea6ac75f. Chain 2 (Bitcoin): anchored in block 953408 (2026-06-12T19:28:13Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

I Know You Know What If I Told You I Like You
If You Were Mine You Would Top Everything
Everybody's Watchin Her but She's Lookin at You
I Dont Want a Valentine I Do Want Valentino
Spendin All My Nights Alone Waitin for You to Call Me
Want You to Make Me Feel Like I'm the Only Girl in the World
When You Put Your Body on Mine And Collide
Cause It's Me You You Me Me You All Night
If You See Us in the Club We'll Be Acting Real Nice
One kiss Is All It Takes Falling in Love with Me
When You Cried I'd Wiped Away All of Your Tears
So I Ball So Hard Motherfuckers Wanna Fine Me
You Want Somebody to Come Bring You Flowers
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

But It's over Then You're Driving Me Home
