Much of the value of HN, apart from the community, derives also from the subtle but firm moderation. I am not sure how that would work on a decentralized system.
- For posting require a hacker coin. - Challenge/wrestle the validity of post by staking some amount of token. - Whoever wins the argument takes the opponents token. - There can be a karma component as well, where in the bad actors need to pay 1.5x amount of token if they did a bad karma last time.
PS : I am not of any extreme opinion that everything should be decentralized. This post was just a thought and so decided to post here.
