      He's smart, he's understated, he keeps doing new logical puzzlement stuff, and he's made a simple application spread worldwide without marketing through word of mouth, and simply because it does what it's meant to well. That's true innovation.

        BitTorrent is a good application, I'll give you that. But it really is just a first-generation application, and should be seen as such. Packet-bartering should be changed to favor those who seed, and if at all possible, priority should be given to giving packets to those who only need a few more to finish their download (since connections slow near the end).

        It's great, but it needs improvement.

        BTW, how long do you think it will be before bittorrent-style downloads become standard in web browsers and web servers? :) I mean, heck, how hard could it be to write such a browser plugin and server plugin? The server plugin would simply need to create torrent files for each actual file that you're wanting to serve as a torrent (and upload those instead), whole the browser plugin would need to first download the torrent and then show the bittorrent download progress (leaving the window open past the end of the download without an option to autoclose, just like regular bittorrent clients)

        It seems that such a feature would make it a lot easier to run a file server on limited bandwidth.

        Also, while I like the concept of the file finding mechanism not being part of the file exchange mechanism itself, as in BitTorrent, we really need a decentralized way to locate and moderate files - some sort of distributed web of trust, perhaps. Of course, those sorts of things are always a pain to try to catch hacked clients, so I'm not surprised that we haven't seen any good ones.

        Oh, and last on my distant-future wishlist: A financial-incentive packet bartering priority boost. I.e., anyone can download, but if you contribute money to the authors of the content you're downloading (this would require a centralized server, no way around it), you get a faster download rate. The more you contribute, the faster your downloads go; your donation distribution could be handled automatically.

    The article seems to imply that Cohen invented multi-source downloading, for example:
    Cohen realized that chopping up a file and handing out the pieces to several uploaders would really speed things up. He sketched out a protocol: To download that copy of Meet the Fokkers, a user's computer sniffs around for others online who have pieces of the movie. Then it downloads a chunk from several of them simultaneously. Many hands make light work, so the file arrives dozens of times faster than normal.
    Yet this feature has existed in other P2P applications for years.

    Personally I think BitTorrent's core advantage over other file sharing technologies is also its core architectural weakness, namely its centralised nature. This allows an editorial filter on content made available through BitTorrent, yet also makes a juicy legal target. Until recently BitTorrent's obscurity has protected it, but clearly this is no-longer the case.

      • So long as a P2P system isn't editing for content, you really can't treat a P2P server as anything but a common carrier. That means you can't go after the owner/operators for the content. Going after content-neutral P2P systems is akin to going after Federal Express for delivering CDs that some customer of FedEx had copied illegally.

    • Okay I get the basics of Bit torrents distributed file sharing. But could someone please explain the details. That is how does the original site know who has what slices.

How is the download=upload actually enforced--what stops me from creating some evil bittorrent that only downloads then hands out shit.

      Not only that, it exists in Kazaa which was mentioned as the "slower technology" in the same article. Yet, in reality, Bittorrent really seems to be faster from what I hear. What is the actual explanation?
      • I'm really not sure which is faster, although if its BitTorrent, I suspect it may have more to do with the usage patterns of its users than the way the technology is designed.
        • I believe that Bittorrent is faster because it links the speed of your download to how much you're uploading in the much vaunted tit-for-tat system. Too many Kazaa users turn of uploading which crushes the network whereas BT punishes you for so-doing... At least that's how the official client works. Some of the more pirate friendly clients might have 'solved' this problem, I don't know.

    Here's something that I've been wondering:

    I haven't looked at the source, but given the broad description of the protocol I'm assuming each "chunk" has a GUID along with the payload. Obviously, this allows for swarming and reduced download/upload bottlenecks, but doesn't it also allow for easy corruption of the data stream?

    For example, when the RIAA tried to defeat Napster by brute force, namely setting up drone/honeypot PCs with libraries of corrupted files, the method failed miserably. I would guess that by its nature, knowing what IP you were downloading an entire file from, it wouldn't be too hard to filter out known RIAA servers.

    But, with BitTorrent handling the gathering of chunks from the swarm from multiple IPs, doesn't that greatly increase the likelihood of success for a similar attack?

    For example, shouldn't the MPAA be able to download the source code and modify encoding so that if (Random() % 1000) a chunk flips some of the bits in the payload? Wouldn't installing this code on a farm of drones eventually "corrupt" the datastreams on BitTorrent?

    Or are their safeguards in place for this kind of attack?

      Yup - each 'GUID' for a Bittorrent block is an SHA1 cryptographic hash. If you find a way of generating collisions for those, many computer scientists and mathematicians would love to know. ;-)

      From the FAQ [bittorrent.com]:
      BitTorrent does cryptographic hashing (SHA1) of all data. When you see "Download succeeded!" you can be sure that BitTorrent has already verified the integrity of the data. The integrity and authenticity of a BitTorrent download is as good as the original request to the tracker. Checking the MD5/CRC32/other hash of a file downloaded via BitTorrent is redundant.

      I gather that if a client was pumping out corrupt blocks, or if they were corrupted at some point during transmission, they'd simply get dropped and re-requested. No idea if there's anything to permanently ignore a client that's pumping out nothing but junk, though - but on a busy tracker, it would get drowned out by all the others. Anyone know?

      Incidentally, is anyone else worried by the way the article concentrated on the distribution of television shows, almost to the exclusion of everything else? I've used Bittorrent quite a bit, but only ever for completely legal purposes [filerush.com] - plus, I've always thought of it being a rubbish way of distributing dubious stuff, what with IP addresses of everyone downloading available straight from the tracker to whoever might be investigating...

        The BT protocol is designed to leave that choice up to the clients. Pretty much all the clients out there will shun a peer after a certain number of corrupt pieces. If there aren't enough peers, it may try again - but it's up to the client implementation.

        The interesting part is that the protocol (or trackers) don't have to deal with those kind of decisions. The clients can each behave however they want, but you are rewarded for playing nice with better connectivity. Badly behaved clients end up with no peers willing to send them data.

        There is nothing gained by writing a BT client that is an asshole to it's peers and nothing stopping you from trying. It will simply be ignored by the other peers that aren't assholes.

        BitTornado [bittornado.com] has a feature for kicking/banning peers who constantly upload junk to you.

        If you're using Bram's official BT client, and there's a peer that's uploading junk, your download won't get corrupted, it'll just waste your bandwidth.

    The big media would love to take him down personally for creating bit torrent, and the only thing stopping them is that Bit Torrent is just legitimate enough to be a hard case to sell. Enough users use it legally, that they couldn't argue it's primarily for piracy. But what if that were to change?

    Bit Torrent is just a tool, it cannot do anything illegal by itself. The user must choose to do something illegal with it. Going after Cohen is no different than going after a gun maker for gun crime. The exact same arguments used against gun makers could be used against Cohen. He's not screening his users, is he? Neither are the gun makers. In both cases, some of their users are committing crimes. Different types of crimes, but either way, a legitimate tool is used for an illegitimate purpose.

    In the long run, the only way to win against the forces opposed to individual liberties is to link our causes. This is the IP equivalent of what the NRA faces with guns, so it only makes sense for both camps to realize we are fighting the same ideology just in two different manifestations.

    Allies, even allies that don't really understand your cause as well as you do, are important. Many of the gun owners' postings I have read on right wing boards frequently have derisive attitudes toward the **AA now and see them as the computer equivalent of "gun grabbers." It's a fitting analogy because the **AA want to be the "computer grabbers." Mandatory DRM is akin to mandatory trigger locks because either way, some bureaucrat is telling you how you must maintain and use your property.

    To protect our rights we must continue to assert individual responsibility as the solution and push for solutions that go after perpetrators of crime, not their tools. That is the only way we can not only cut down on crime, but also protect people like Cohen from amoral, mercenary attorneys like those behind the **AA

    I read the article (no, really!) and found it to be mildly interesting. What bothered me, though, are the statements that, basically, "the more clients that are uploading pieces, the faster the download gets"

    That's all fine and dandy, but the author makes it sound like this gets around the limitation of one's own pipe to the Internet. If you're on a modem, there's no way you are going to cut down a 500MB download from hours to a few minutes, yet the article has a paragraph that implies that an hours-long Kazaa download is cut down to a few minutes with BitTorrent.

    Obviously, if the limiting factor is the source pipe, then more sources equals faster download at the destination. This kind of writing bugs me since it doesn't mention such obvious limitations -- it all sounds "miraculous" (or "marketish"?).

    Found a picture of the Math team back in 1993 [mojo-working.com]. Bram's the guy with the bushy hair in the back row near the center next to the tall asian guy and another guy with a hat. He was the co-captain of the team that year, if I remember correctly. I think he ended up in the State University of New York at Buffalo. That always bothered me for some reason. He definitely was smart enough to make it into a better school. Why did he choose to go to Buffalo?

    heck, you could probaly do it with one library and some implementation details in the browsers, as most are written in C or C++.

    Just a protocol just like http:// ie bt:// that delivers the content to the browser for display.
