What is the decentralization of Bittorrent Sync?

Question

Backup

I was thinking, what is the decentralization of Bittorrent Sync? Here I will install it on my Raspberry pi, and it, in fact, will be the same center as, for example, the DropBox server. Or, if there is the same file on my Bittorrent Sync as on the file of some other person (for example, some kind of movie), then I will pull it simultaneously from both places? And a bonus: if so, will Syncthing (an open analogue) work as well?
Thanks in advance.

Answer 1

There is a dropbox client application, there is a server (center).
In decentralized systems, there is no client application, it is both a client and a server at the same time. In case of failure of one of the nodes, the rest continue to work. If the dropbox server fails, nothing works.
Actually, btsync is not completely decentralized, as I understand it needs an initial synchronization with the bittorent server to get the IP addresses of the nodes on the network.
Bittorent itself is decentralized, it works even in LAN without an Internet.
