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
Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0xb1ce355056ae0f33f5aecca6bb82a8ffd072449c54eeac74bd8b4a7c8cb2f5ed. Chain 2 (Bitcoin): anchored in block 953730 (2026-06-15T02:47:28Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Music for Keyboards Vol. III: Symphonie No. 1 "Patriote"
Your Father Used to See Airplanes in the Sky
Monsanto Gave Us Verdant Fields and Fertile Soil
That With Thy Saints I May Praise Thee Forever and Ever, Amen
From the Root of Jesse Proceeds a Splendid Flower
In the Presence of Unborn Christ, John the Baptist Leaps for Joy in Utero
The Voice of the Father Is Heard As the Spirit Descends Upon the Son
Peter, James and John Climb the Mountain to Pray
Radiant With Glory, Christ Transfigured Speaks to Moses and Elijah
With a Mighty Rushing Wind the Disciples Speak in Other Tongues
The Apostles Lose All Fear and Boldly Confess Christ Crucified
Christ in Heaven Sits at the Right Hand of God the Father
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 → block OTSBitcoinBlock must exist at that height 4. Confirm CopyrightID is the CopyrightChains transaction hash 5. If all match: the cc-db-prod record is independently anchored on Bitcoin at OTSTimestamp
