I have thought a long time about decentralized applications and their advantages, especially the fact that they tend to be more reliable and cheap when there are a lot of traffic involved, something that is not true with centralized applications (best example is facebook or google, those servers burn a lot of energy).
My question is this:
Can Kademlia be used for a chat protocol, and how secure would it be ? If I enable packet encryption, would privacy be guaranteed ? Are other kinds of messaging applications possible with kademlia (forums/usenet, email, IRC) if I adapt the protocols ?
I’m sure I’ll need to add a lot of code to make it privacy effective so that anyone can eavesdrop or exploit the Sybil attack (described on wikipedia).
What do you think ? Do you think this project is worthwhile ?
(sorry for my bad english)
Kademlia is a mean to locate and exchange distributed information on peers. It is not related to security. You can implement security on top of it for sure. The best option is a public key encryption system with certificate authority. You would have to encrypt the data.
Anything is possible on top of Kademlia.
