Hi, i’m thinking about decentralized apps for a few days, and found out that there is no fully decentralized app. We have several nice apps like Akasha, Leeroy, OpenBazar, D.tube, but all of them except Leeroy can not be named as decentralized apps.
For example Akasha. Akasha is using ipfs and ethereum networks. When user is registering, akasha is send coins to this adress, bcs we need to pay for gas. So, we have at least one centralized server, without which the system will not work.
More decentralized app from my list is Leeroy, bcs they are using Ethereum blockchain for storing their posts, but it’s expensive, for example when kryptokities was started, gas price was about 2 . I dont think, users will pay 2 or more for posts.
I thought how to build decentralized messenger on top of ipfs. Everything will be fine until one node goes offline. And if we need caching server, we can not name this app as decentralized messanger.
Maybe someone knows a nice example of absolutely decentralized app? Without any centralized “ping” or “caching” server?
