Block chain is the only one in your list that is actually decentralized, and it winds up de-facto centralized anyway because it's too slow. BitTorrent is centralized around the search engines, because a content-addressable storage system can't help with content discovery. You need someone to delete torrents that claim to be video games but are actually ransomeware. FreeNet is the same as BitTorrent, except that it has built-in support for updatable "freepsites," so the content directories are built into the protocol instead of being run as regular websites. Also, it's anonymous, and kinda slow. It's actually really cool, and horribly underrated, but it doesn't actually solve the schelling point problem. Which freepsite do you trust to have factually correct information?
