| Sounds a lot like emule / edonkey
Emule and Edonkey has had a very similar way of sharing files for years, a hash (MD5) is produced of the file and of the individual chunks of the file, on a web site supporting edonkey links you just click and the file you get is guaranteed to be what you clicked on, it works well for large files (movies) but you have to give it time to work, a well spread movie may take several days or more. |

| Very similar but for some reason files spread much better the way bit torrent does it. I can even seed 600mb files on my slow 30k/sec upstream in less than 24 hours, it takes days to do that on emule. By seed I mean if I stop sharing there are enough people sharing the file still that others can download, with emule I have to share for days to make sure they are spread enough so others can download while I'm offline.

| Yes. This works because bittorrent makes one "list" or central server keeping track of everything. So pretty much instantly, you can get ahold of a list of all users and be able to fill up connections. With edonkey,gnutella,etc there is no central server, and thus it takes much longer for the message (and user "list") to be passed along.
Imagine the differences like this. A message being send across the "grapevine," from one neighbor to the next. "Did you hear? bob got a new car!". Vs an announcement being made on the local newspaper. Everyone picks up the paper and gets the whole information on the spot, instead of running around and getting bits and pieces together.
The benefit of central is speed, but the benefit of decentralized is it can't be shut down (and "no one" to blame). |
