How do voice and steemit social networks work?

Question

Social media

I came across the other day on the social network voice and became interested. I began to read articles-explanations in Russian and in English, it seems that something has cleared up, but I still don’t catch up to the end. The following points are not clear:
1) Who generates the cryptocurrency in this case? At first it seemed to me that it was generated by publishing, but then it seems like - no, by some special servers.
2) How do posts, comments and likes (dislikes) and the authors themselves participate in the generation of cryptocurrency? That is, what is the relationship between the actions of participants and generation?
3) How can a distributed chain of blocks be stored "on all computers"? It's probably a huge amount of information, isn't it? From the video it turns out that each participating computer stores this chain, or are we talking about parts, something like a torrent?

Answer 1

The more you are in the trend, the more expensive your likes, comments and posts.
This is a normal amount of information, as the same bitcoin stores everything
