Well it seems like Qortal, despite being blockchain based, is aware that many blockchain projects are flawed or outright scams. They seem to have taken effort to make sure that Qortal is actually decentralized by making all users nodes, and the extensive documentation probably means that they are WAY more competent than nofish (the ZeroNet dev). They also plan to include mesh-networking in the long-term, so this can even circumvent the physical structure of the Internet.
Though like ZeroNet, Qortal still has one flaw in that it seems like you need an account to post ANYTHING. Which makes it less than ideal for completely anonymous sites like Pastebins and imageboards, not like anyone would trust a completely P2P imageboard anyway.
