Read this article from Andrew Birmingham of Which50. The focus of this piece is the application of blockchain technology in digital advertising.
Praneet Sharma explains that the main blockchain networks cannot and should not handle the scale of digital advertising. He argues that a good capability would be to “side-chain” information into a separate blockchain and merge it back into the main one, because this is required for impression-level tracking. For other applications, such as supply verification, the transaction rate is not of much concern.
