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 0x4828724e467dcbb9ae1a155409df93fa0eeb1d82b03010794426468e6cc3ef90. Chain 2 (Bitcoin): anchored in block 954014 (2026-06-16T22:46:20Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Khat Fatima Sughra Ne Ye Baba Ko Likha Hai
Roz e Ashura Subah Ko Dee Jo Akbar Ne Azan
Ro Rahi Hai Aaj Tak Shabbir Khak e Karbala
Mera Hussain Bagh E Nabuwat Ka Phool Hai
Yeh Musalmano Rasool e Pak ka Farmaan Hai
Vichora Bibi Sughra Kyun Mere Veer Nahi Aye
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
Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0xee6737f1ff106ae392e0b09820f16451a166492b530888dd3b2b05a81edcbc43. Chain 2 (Bitcoin): anchored in block 956772 (2026-07-05T10:01:46Z), registered by our registry partner.
