AlterEgo is a proprietary wearable silent speech output-input device developed by MIT Media Lab. The device is attached around the head, neck and jawline and translates muscular and neural activity in
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 0x0941ba9e8b9f909503ae88fde3c292ed45041646cca96f88ee389c188eed1095. Chain 2 (Bitcoin): anchored in block 954081 (2026-06-17T10:15:47Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.
