A bitcrusher or bit crusher is an audio effect that produces distortion by reducing the resolution or bandwidth of digital audio data. The resulting quantized noise may produce a "harsh" or a "filtere
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 0x2236ffb635ae66e8f5844a07abb602b87c6ad055572fc9722a82d67492bfe067. Chain 2 (Bitcoin): anchored in block 953949 (2026-06-16T13:28:01Z).

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
Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0xa16034c26589ba0c764e76e396cf731c7cd7dc27cc579f8ab4769c45254f45bb. Chain 2 (Bitcoin): anchored in block 958761 (2026-07-19T20:03:48Z), registered by our registry partner. The server verifies the private canonical record against OTSHash without exposing internal provider keys.
