i think the easier way would be to sell banners under every post. So the banner will be integrated into the post if someone wants to advertise there. This could easily earn the author rewards. In addition, the advertiser could pick and offer the posts with the best quality.
I am not a programmer. But I know the system would work 100%. Since we see the same as a revenue model on Facebook, google and co.
And it wouldn't be long if the posts were good, that very large advertisers were buying advertising.
Technically, I think it should be easy to do.
Mark advertising space in the post, and a bid window for advertisers.
Advertisers can bid with HDB and Hive.
And we have one more usecase.
Each frontend would show the advertising as it is in the post.
The rewards can flow 100% to the author. That would be revolutionary and 100 times better than the competition.
Then you could exchange upvotes with likes and dislikes and let SMT do the rest. Or the inflation from hive to 0.
