Abstract
Blockchain-based proof of presentation of content on a media channel, including: generating, upon receiving a request to generate, at least first, second, and third parameters, wherein the first and second parameters are input parameters and the third parameter is calculated as an output parameter of a one-way cryptographic function; generating a first type of block by incorporating the first and third parameters into the first type of block; validating the first type of block and the blockchain; appending the first type of block to the blockchain when both the first type of block and the blockchain are declared valid; and embedding the second parameter into the content that is to be made available on the media channel to produce tainted content.
