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 0x68549dabbe69d56e18c60f5b6b9ce931a696fcbb0807bc4dbb3b8ed6df4c1c7f. Chain 2 (Bitcoin): anchored in block 953407 (2026-06-12T19:24:56Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Loving you is a curse (Lyubyty tebe proklyattya)
In poems, I replace dots (U virshakh zaminyayu krapky)
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

I will be happy for you (Ya za tebe tilʹky raditymu)
An actor in my own play (Aktor u vlasniy p'yesi)
I remember "us", from the very prologue (Ya pam'yatayu «nas», iz samoho prolohu)
Love is silent sometimes (Kokhannya buvaye movchytʹ)
Let the whole world deceive me (Nekhay obmanyuye mene vesʹ svit)
I will never forget you (Ya nikoly tebe ne zabudu)
This time without "I love" farewell (Na tsey raz bez «lyublyu» proshchalʹnoho)
You know, but I miss you (Ty znayesh, a meni tebe ne vystachaye)
