What block chain is on the so-called block chain introduced

Under some recent understand, is that my opinion on the "block chain". . .

1 to the center of 
the so-called decentralization, but not without the center, but there are a lot of centers, is a so-called point can be called the "center."
2 distributed storage
" distributed " is relative to a central point for the. Because there are multiple points of center, so called " distributed " in.
This is on top of the so-called "block chain" concept, that is, the game in general settings. Nothing big on things.
Nora once because only one cache server data center, as found inside this illegal information is removed. Then someone said, if Nora to soon adopt "block chain" technology, maybe there would be a problem later. is it possible? Think maybe impossible.
It was the idea of 1:
a "block chain" technology, all of the video files using decentralized databases, computer software for each client, as a little every video file on this chain is split into smaller point files are stored encrypted on the disk to install the client machine. A video store or several different videos on each machine, the same or different files stored on a plurality of machines. (Avoid some turn, some do not turn, so as not to affect the integrity of watching the video) ---- imagination is good, but his execution, really undesirable. So many massive video files, limited storage space at each point, affected by bandwidth limitations, it may just be a good idea.
It was the idea of 2
client the whole point of storage, each video file as the complete storage, such as on top of the same ...

Of course, on top of just a few ideas based on so-called block chain set, bottom turn by everyone think the block chain rules of the game:
such a requirement, there are a lot of points, the same record-keeping information stored in various places, every place is secret.
And then it provides a point if you want to modify the data, how come everyone in sync. If you are not synchronized, while he secretly modify a data node, it is not recognized, and so on.

Rules of the game was set up, if the wood was nothing to play. And now everyone wants to play, in the end this what fun it?
If there is a 1000000000000000000000t data, if only by maintaining a central point, it is still possible, if you press the top of the play, to build a multi-n junction, that was how much to invest, how much they have to maintain it? Really is not an ordinary person can play played.
May in some ways, this game is also a good idea, feasibility and how much can it?
