I was thinking about this the other day when I was out for a run. BitCoin seems to have an implementation that works and is secure, but people donate a large ammount of computational power to validate that data. I look forward to reading deeper into it and seeing what applications people come up with.
Interesting idea! I wonder how they think to address performance (one data query needs many requests to different nodes if I understand it well) and availability (if one node is down, I can't access my data?).
Anonymous and decentralized do not mean the same thing.
