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 0x5f55257ccf1e7ab6c4dbd4c0f7dc9b8df4da2a81323dbb9c7f12d43324623492. Chain 2 (Bitcoin): anchored in block 954066 (2026-06-17T08:11:48Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Aus einem tiefen Tal in deinen Königssaal
Ich bin da, wenn du nach Liebe dich sehnst
Du stillst die Sehnsucht ganz tief in mir
Mit den Augen meines Herzens möchte ich sehen
Herr, ich bin dein, was auch gescheh'n mag
Wenn Du erscheinst, sind wir wirklich bereit?
Mit dem Herzen, der Seele und all meiner Kraft
Die Gott lieben, werden sein wie die Sonne
Kann ich es vergelten, hab ich es verdient?
Wir schau'n auf Jesus Christus, unseren Herrn
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

Ein Fundament, aus Glauben fest gegründet
Mit wieviel Liebe erschufst Du die Welt?
Dann jauchzt mein Herz Dir, grosser Herrscher, zu
Lass den Strom der Gnade nicht versiegen
Ein Name und ein König (Special Version)
