I want to build one too. In mine you will only be able to watch 50% of the video and if you want to finish it, it will cost you 2 Satoshi. 1 Satoshi goes to the content creator and the other goes to the website owner. You can also zap the vidoe as much as you want. For example if I zap 21 sats, 20 sats will go to the content creator and 1 will go to the website administrator.
In the comments of the video it will cost 2 Satoshi to comment. This will keep spammers from commenting in the comments.
Many of these type of things so it keeps spammers and freeloaders away.
