Abstract (en)
[origin: WO2022248965A1] A Proof of View verification system is disclosed. The Proof of View verification system has a Non-Fungible Token smart contract module, comprising computer-executable code stored in non-volatile memory, a Proof of View smart contract module, comprising computer-executable code stored in non-volatile memory, a processor, and a verifier network. The Non-Fungible Token smart contract module, the Proof of View smart contract module, the processor, and the verifier network are configured to transfer a data of a non-fungible token to the Non-Fungible Token smart contract module and generate an event metadata based on the data of the non-fungible token, transfer the event metadata to the Proof of View smart contract module, and generate an event hash using the verifier network and transferring the event hash from the verifier network to the Proof of View smart contract module.
