"SZNS" (pronounced "seasons") is a song by American singer Dinah Jane featuring American rapper A Boogie wit da Hoodie. The song was released on July 25, 2019. Background "SZNS" follows the release o
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
Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x7bbab87b3df930bf3aa7e7ef12d274d2853813f126ee0799cd9bbff30330203a. Chain 2 (Bitcoin): anchored in block 953407 (2026-06-12T19:24:56Z).
