Verasity has a US patent on it's technological breakthrough known as POV, Proof-of-View.
This allows Verasity to verify and authenticate whether or not advertisement has been watched by a human or a bot. 

Now you may ask, what's the value in this and how does this help.

The Advertising Industry is a 400 Billion Dollar industry as of 2020 and expected to massively grow as the restrictions of Covid is lifted.
Out of that $400 Billion, roughly $160 Billion is wasted on bots.
Not only does the businesses, (big and small) waste their money and opportunities in the future, but they are demotivated from paying for advertisement again. Not only that but because of the lost potential revenue, this prevents additional expansion, hiring, etc.
This hurts content creators who rely on this revenue to keep producing content which ultimately impacts the Viewer.
