US Patent 10956931 System and method for proof of view via blockchain

A Proof of View verification system is disclosed. The Proof of View verification system has a Proof of View verification module, comprising computer-executable code stored in non-volatile memory, and a processor. The Proof of View verification module and the processor are configured to receive a request for a content view to view a piece of content, record a content view data in a database chunk, hash the database chunk into a hashed database chunk, append the hashed database chunk to a block on a blockchain of the Proof of View verification system, and compare the content view data with the block on the blockchain. The blockchain is publicly available.
