In Greek mythology, Theia (; ) also called Thea, Thia, Euryphaessa, Aethra or Basileia, was one of the Titans, the children of Uranus (Sky) and Gaia (Earth). Her brother-husband is Hyperion, a god of
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 0xe088009bedd37904f5e0774649068bece5016d346b7dacc141054374afa63288. Chain 2 (Bitcoin): anchored in block 953633 (2026-06-14T12:47:11Z).
