      Is there a GPU miner for this thang yet? All I’m getting are rejects!

      Any pools or is it being premined as I type?

      I don’t see any source code (Warning possible wallet stealer or Scam Coin!).

      Is this scrypt?

      What port do I use?

      Any other nodes?

        I am very interested in seeing this idea through, it could be one of the major talking points which takes us from “clone” to Feathercoin. I think having torrents embedded in the blockchain is a great first step, if we could get a website like TPB on board it could be huge!

        Kevlar: Would this protocol have to be accessed via TOR?

        PS. What is in the bitcoin block-chain which is copyrighted?

          It would require a bit of resources to do, but it’s entirely possible to do it. Getting the index into the blockchain is easy. Having the coins to spend… a bit trickier.

          You wouldn’t need them to do anything. It’s the type of project a clever kid with some python skills could whip up in an hour.

          Nope, it just layers into the existing blockchain protocol. No changes to the blockchain required.

          Well I know someone embedded DeCSS in there, which is the famously copyrighted number. My buddy Dan Kaminsky did a bunch of work on this a while back.

            I would match someone up to 100 FTC for this project and some of my personal time. I have some computer programming experience (pascal :o , Visual Basic, and Python) but am definitely rusty. What would the python have to do exactly?
            EDIT: Sent 5.666 FTC to your sig address Kevlar, hopefully that gets a few more lines of code into this project!

              I’m already hard at work on it. Your donations are GREATLY appreaciated. :)

              The python would have to read the pirate bay database, and insert it into the blockchain by spending the coins using the Link protocol. I’ve not yet calculated what the cost of a message will be, but I do estimate you can do several hundred thousand torrents for 1 FTC.

                So are we just storing torrent files in the blockchain? Torrents are notoriously resistant to adaptation. There is no torrent modify protocol or dynamic torrent. For example, there is no torrent proxy which can turn a folder being shared into a torrent file in real time.

                I’ll work on FLUX and see how it fits here.

                  That’s one possibility and you can do that with the Link protocol but I’m working on something a little more efficient in terms of storage. Why store the whole torrent when you can store a tiny fraction and accomplish the same thing?

                  As for modifying torrents, torrents are like URLs: you don’t modify one, you use a new one. That’s an important feature, because it means the same data will always be downloaded for a given torrent. Want different data? You wanted a different torrent.

                  Making them a directory at a time is trivial.

                    Is there any way the concept of holding the magnet files can encourage or push people to use i2p for further security?

                    I’m just envisioning people running the Link through Tor and going “Huh! It’s good enough for that. Let me go ahead run my torrent client through it.” and having a small nightmare about it.

                      See that’s what I was hoping for. Because many torrents are actually collections of files. This makes more sense. I still think link could be more dynamic. Like forking a linkchain for different remixes. Or updates to documents in progress.

                      Except we also have urls which are actually queries formatted as directories for search engines to crawl, which would mean blockchain search engines.

                      I really should just build this feature and stop whining about it.

                        Well they can run the blockchain download through the Tor network. That’s easy to do. I personally run my uTorrent over Tor and while I won’t max my bandwidth that way, it works well enough.

                          Ok, I’ve made a few changes to the initial pass. Specifically I’ve changed it from a fixed-length block-based encoding scheme to a variable-length stream-based encoding scheme based on op-codes to maximize compression and minimize wasted space in the blockchain.

                          Now is the time to get your op-codes submitted for inclusion. The list is far from complete, but please read the description of the ones suggested so far and if you have any ideas for other ones please let me know!

                            Is there anything someone who doesn’t have cryptos to donate, and doesn’t have the underlying computer skills, can do to help? It think this idea is brilliant.

                              I would do this for opcodes:
                              1st byte = module slot
                              2nd byte = module function

                              So what you have defined so far is module 0 - the core link module. I would move 10, 11, FE, FF to 0A, 0B, 0D, 0E.
                              Module function 0 for all modules is the module key. Module function F for all modules is the extension range. Function 0 would identify the module we expect to be installed there. Function F would allow us to extend a module over several slots.

                              The module key could be a digest of module name, version, VFW Post, geocaching GPS info, and other identifiers - they wouldn’t need to be listed, just the digest would need to match. The extension range would tell us the beginning and ending module slot which are allocated.

                              So core module/module key = Opcode 00. The extension key just points to module slot 0 as beginning and end. Say module 1 is a track list and module 2 is a list of ratings. Then track list/module key = Opcode 10 and ratings list/module key = Opcode 20. Both would also have extension range with beginning and end 1,1 and 2,2.

                              This means 14 functions per module slot. It allows for extreme extending of any concepts we want to add without getting lost. Core module in slot 0 is reserved for basic link protocol. I would suggest reserving slot F as well. The rest can be used by extenders. That leaves 14 slots of 14 functions each, for whatever we want to do. There is some duplication of info, but that may be the best way to do it.

                              If this isn’t too weird, I’ll set up FLUX (Flux Link Unit eXchange) functions within this same scheme.

                              One thing I would add (Peter Falk voice): some of these functions may require read write capability, but that’s for another time.

                              One favor Kevlar, I want to be able to read these streams from nodejs just for correctness in encoding. I might need to check with you on that.

                                Yeah, I’ve thought about a version scheme. It wouldn’t be hard. You could just say that this transaction succeeds this prior transaction, and sign the whole thing for security so only intended authors could version.

                                Yep, I’m probably going to be doing the same in my initial pass. I’ve not decided on a language just yet. I’ll be sure to post anything nodish. Sails.js is lookin’ pretty rockin.

                                  I’m gonna experiment with soft-reorgs here. If it works we can expand it to end 51% attacks. This would allow a safe environment for large and small currencies unencumbered by the philosophies of big players or unreasonable devs (ONE TROO COIN).

                                      The danger from 51% comes from two places:
                                      1. 2 options - accepted or rejected - this gives us the > 50% value. FIX: create partial transactions, leading to more options, which will then require n-1/n of the network to override given n options.
                                      2. no barrier once you cross the threshold - this means reorgs are free. FIX: make reorgs cost processing power

                                      #1 is a logical puzzle and will take some sideways thinking
                                      #2 can be implemented as a feature and generalized

                                      ACP is a crutch. It will be removed eventually.

                                      There are a couple more subtle reasons. But we’ll leave those for later.

                                          Ok, Payload op-codes are in, Meta-data op codes are up next. Also ZD’s organizational changes to op-codes has been implemented. 0 is Payload, 1 is Meta-data, and F is sequencing.

                                          Anyone else have any other op-codes they would like to see?
