Right! That&#x27;s why I think fully distributed peer-to-peer is the wrong goal to strive for. A lot of group activities (like posting to a topic and voting) are much more easily done in small cohorts. Yes, mental poker is possible but it&#x27;s in its infancy and our efforts are currently better spent assuming there are going to be servers. The question is, can we choose what servers! The DHT can route you to a server which is authoritative for a particular group activity. That allows you to clone some post and share it with your friends (on a server you trust) and they can reshare on servers they trust ...As you said, what is needed here is not consensus but just signaling from people you KNOW.<p>The rare resource here isn&#x27;t work, it&#x27;s reputation. You personally won&#x27;t add 1 million friends. If you want to get signals and votes from friends then you don&#x27;t need proof of work.
