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 0xdc496e82e78ce910d7a1c2db892d9b6bdb60052fb1589c1bdb7dc7b22094fb70. Chain 2 (Bitcoin): anchored in block 953407 (2026-06-12T19:24:56Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID. Verify: download https://artists.proofprofile.net/proofs/artist/f72e1ec2-a04e-4ad1-97f8-d680f6e3fd9e.json and https://artists.proofprofile.net/proofs/artist/f72e1ec2-a04e-4ad1-97f8-d680f6e3fd9e.ots, run `ots verify -f record.json proof.ots` (https://opentimestamps.org).
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

雪花别为我难过 (雪花雪花你别笑我)
敬往事一杯 (如果有来生请你等等我)
学会把伤隐藏 (我会保证爱你一万年)
后来你的故事我还会听说 (和她也分分合合)
敬往事一杯(白头若是雪可替世间何来负心人)
敬往事一杯(珍惜每一分钟在一起的时间)
忘了爱过谁又被谁爱 (别去碰往事別让泪滑落)
爱上你我犯了什么罪 (掏心掏肺换来心如死灰)
想哭的夜没有下雨 (我的心里还装满了你)
来生我等你娶我为妻 (你是我唯一动了情的人)
