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 0x308e8e90e20e98502384b85bf9ec31a4fa1c3f2f63952d8abdec306954574ffb. Chain 2 (Bitcoin): anchored in block 953770 (2026-06-15T09:50:11Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Pray (Until It All Means Nothing) [Acoustic]
She Knows Who She Is, She Just Forgot for a Little While
Living by Your Wits Is Always Knowing Where the Wasps Are
I've Thought Myself Out of Happiness a Million Times
What We Know Is a Drop, What We Don't Know Is an Ocean
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

Our Last Song Had a Short Title, but Now We're Back With a Vengeance
If You're Gonna Dig a Hole in the Yard, Better Make It a Big One (Live from the RedRoom)
Stop Thinking In Straight Lines (Live From The RedRoom)
You're So Vain, You Probably Didn't Think This Song Was About You
All My Life, My Heart Has Yearned for a Thing I Cannot Name
I Fear Only That My Rage Will Fade Over Time
