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 0x36c94331032e63ea43b7e4ac6afda3053be8bc85e28aa57409450499be465d56. Chain 2 (Bitcoin): anchored in block 954689 (2026-06-21T10:35:31Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

愛は風にのって, 子猫のスーちゃん
愛は風にのって, 笛吹きと縄文土器
愛は風にのって, 琥珀色の秋の夕暮れ
愛は風にのって, 黒のタートルネック
愛は風にのって, ほのかな冬の灯り
愛は風にのって, 揺れる煙と眼差し
愛は風にのって, セーターの贈り物
愛は風にのって, クリスマスの思い出
愛は風にのって, 子猫のすずちゃん

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
