The DHT is good, although I wonder whether the routing is centralized through relying on DNS, or whether it&#x27;s completely decentralized.<p>What is the point of the blockchain, though? Is it just to avoid a double spend problem? Proof of work is terrible now for new blockchains because people have rigs that can easily execute a 51%+ attack and destroy the network. It needs proof of stake, which becomes better the more participants there are. But proof of stake has a more centralized character not unlike a website with moderators controed by the initial host.<p>Isn&#x27;t there a better way these days to prevent sybil attacks? All you need is to make it very expensive to make more than one account. How do you do that? You take what 99% of people have one of (such as their body, or their house, or their cellphone) and have them prove they own it. But that defeats anonymity, doesn&#x27;t it?<p>Isn&#x27;t there anything that people have only one of, can prove they own it, but doesn&#x27;t reveal their identity?<p>Someone should implement this. THAT would be the real way to prevent sybil attacks.
