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 0xf23b5e804850080616972b6ecc4cb73d154873e3df62901a0cc835cfe141bd4d. Chain 2 (Bitcoin): anchored in block 953770 (2026-06-15T09:50:11Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID. Verify: download https://artists.proofprofile.net/proofs/artist/ae443a79-4f85-4862-af42-d065259e4005.json and https://artists.proofprofile.net/proofs/artist/ae443a79-4f85-4862-af42-d065259e4005.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

大をした直後の便器の中スマホを落とした
何もしてないのに休日が終わった
高音厨音域テスト (暗黒バージョン)
焼肉代が医療費控除にならないのはおかしい
スーパーのパックの寿司の醤油が少し足りない
こうおんちゅうおんいきテスト (ぜんねんれいバージョン)
初投稿のボカロ曲なんてこんなんでいいよ
高音厨音域テスト (本人が歌ってみた)
おちんちんから醤油が出たならば
おしりから柚子胡椒が出たならば
私の曲を全国民が一度ずつカラオケで歌えば印税で暮らせるのに
高音厨音域テスト (10周年バージョン)
「さすがにもうこの曲聞いてる人はいないよね？」
穴のあいた靴下をまた洗濯してしまった
全裸で街を歩いたら警察に捕まるのに国から洋服代がもらえないのはおかしい
