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 artist was registered on CopyrightChains at OTSTimestamp, independently verifiable on Bitcoin
Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0xaf3b5a7dda67e80673ce2f91a067ff7f8128e68ff5fc3eaf5b18089ad60b7750. Chain 2 (Bitcoin): anchored in block 953742 (2026-06-15T04:47:56Z).

ברכת כהנים, יהי חסדך, אל הנער הזה, רבון העולמים, הנה ימים באים
מים רבים, תזכנו, חננו ה', ותיק, הנסתרות, תפילת אמהות, עד מתי
שערי דמעות, אזכרה, עד אנה, השבינו, השבת, זכור ה', קץ הפלאות
