+<slvr> This can be trivially solved by only storing verifiable data in the DHT.
+<slvr> there is one attack you have not considered, which is based on the Sybil 
+attack
+<slvr> I am assuming the DHT does say... a hash of a key in order to determine 
+which node to store data in, similar to Kad?
+<slvr> If there happens to be a malicious node at that DHT address, they might 
+actively deny storing that data.
+<slvr> This can be reduced by storing data at multiple places in the DHT 
+(equidistant points in DHT address space)
+<slvr> Since DHT addresses are public keys, it is computationally infeasible for 
+an attacker to actively deny all storage locations.
