Twister: The Fully Decentralized P2P Microblogging Platform 169

Posted by Unknown Lamer from the not-at&t-approved dept.
New submitter miguelfreitas writes "I'd like to offer for discussion with Slashdot readers this new proposal: twister is the fully decentralized P2P microblogging platform leveraging from the free software implementations of Bitcoin and BitTorrent protocols. This is not being pushed by any company or organization, it is the work of a single Brazilian researcher (me). The idea is to provide a scalable platform for censor-resistant public posting together with private messaging with end-to-end encryption. The basic concepts are described in FAQ while more in-depth technical details are available from the white paper. The twister network is running already: the client can be compiled for Linux, Mac, and Android. 2500 usernames were registered in the first 6 days."

        Yes, but your counter-troll failed harder. A company I was working for got bought out by IBM, and I was really excited about it, because from the outside they looked like they were making a huge push towards using linux as their primary OS, and open source software in general. (I ended up working for them for about 5 years.)They managed to get Notes, their primary communication tool, working almost as well on Linux as it worked on Windows... which is not particularly well... but they haven't even ported over many of their basic tools, such as their ticket tracking systems, which are used to track development as well, to Linux. As of a few years ago, they said that they were going to stop attempting to port those tools over. For server operating systems, in many applications, they're still relentlessly pushing their developers to concentrate on coding for AIX over linux.

        They've got a bright shiny image put forth from their marketing department as one big unified force pushing for workplace innovation, but the way the company actually works is much more like the government Terry Gilliam's 'Brazil.' Their linux workstation project was an underfunded, disorganized yet highly publicized project put together during their big linux marketing push. I don't even think 25% of the company directly touches linux on a daily basis, let alone the absolutely laughable assertion that 90% of the company uses linux as a primary desktop OS.

      Apropos of nothing, where are you getting this meme?

      I only ask because it doesn't happen to be true [bitcoin.it], yet it's an oft-repeated meme that everyone seems to put forth as the BitCoin "killer" flaw.

      tl;dr Here's the relevant passage from that link:

      It is not required for most fully validating nodes to store the entire chain. [...] the size of the unspent output set is less than 100MiB, which is small enough to easily fit in RAM for even quite old computers.

      If one wanted to kill an idea, if one wanted to wage a propaganda war on an extreme viewpoint or tool, here is one way to do it.

      • 1) Assume people know the basics of the system, but not the details.
      • 2) Construct a "problem" consistent with the basic knowledge
      • 3) Loudly advertize that "problem" and let others pick up and repeat it

      It certainly seems plausible given the basics. Every transaction will add to the blockchain, and we process a whopping-big number of financial transactions every day! The blockchain will soon become unmanageable, and BitCoin will fail!

      I've seen this in other arenas, including politics. Al Gore invented the internet [snopes.com] for instance. He didn't, he never said that he did, but he did say something vaguely similar. It certainly seems plausible that this is what he did say, and boy what a gaff! It makes him look sooooo silly!

      We should promote our own agenda this way - the UK spam filter, for instance. What right risible meme can we invent that is close enough to reality that people would find it plausible, repeat it, and use it to label the filter as badly conceived?

      Let's use the the same techniques our opponents use. Human psychology, for the win.

      • It is not required for most fully validating nodes to store the entire chain.

      As it is explained in the FAQ, the blockchain is not used for distributing user's messages. Only user registration and authentication is based on the Bitcoin protocol. The blockchain only grows in proportion with the number of registered users, with a few hundred bytes per user. Even with a widespread adoption that is still a quite managable size we are talking about.

      Mmm... social networking and telecommunications on a decentralised network with no way of inserting advertising

      Actually, it does. From the FAQ [twister.net.co]:

      Can I mine Bitcoins with twister?

      Not exactly. The same mechanism used in Bitcoin for mining is also used in twister but for a different purpose, ensuring the order in which user registrations took place (the nickname belongs to whoever registered it first). twister network must incentive users to mine, so block chain may keep advancing. However, unlike Bitcoin, there is no monetary value involved. The twister incentive is: whoever finds the hash collision to validate a new block of transactions will be awarded with the right to send a promoted message. Promoted messages have a certain probability of being displayed by twister client.

      Promoted messages? Am I going to be flooded with SPAM?

      No, I hope not. I don’t like promoted message any more than you do, but I believe that a fair balance between the allowed volume of promoted messages will not upset the users while providing a good incentive for people to run the twister infrastructure.
      Currently there is a maximum of one promoted message to be shown every 8 hours for every client, but the exact policy to be used is meant to be decided by the community.
      The mechanism is actually quite democratic. Anyone can start generating blocks to send promoted messages, so this is effectively an advertising mechanism reaching the entire population of twister users. While an entrepreneur may invest in a mining rig to announce his product, a non-profit organization may ask his supporters to use their own personal computers to increase the probability of spreading their message.

Twitter would have everything to lose (in terms of bad PR) and nothing to gain from a lawsuit against a hobbyist Brazilian developer; considering the delicate state of US-Brazil relationship after the NSA leaks, the political world would

      Windows is a notable but minor OS among software developers in the crypto-anarchy scene. Provided the project picks up steam a Windows build will come along soon enough. There are more important things to do right now.

    • Most of the users who'd want a windows client will be using it on their phones anyway.

  • A while ago I said Twitter should be an RFC, not a company. Nice to see that somebody is doing that kind of thing. The catch is adoption. If most people don't adopt, it doesn't work. An in-browser client written in JavaScript would help that, if it's possible. In the 21st century, people have gotten used to the idea that you don't have to download a client for each protocol. Yeah, it sucks to have everything in the browser sometimes; but that's reality.

      Twister has a local daemon which handles connections and serves an HTML UI. So yeah, the interface is in-browser, but you still need a background client: it's the price of total decentralisation. (this said, once technologies like WebRTC mature, it might be possible to implement all of it in-browser, but I wouldn't hold my breath).

    For distributed, peer-to-peer solutions to work well, many users MUST allow significant storage on their own machines. Without such storage, P2P solutions will lack a 'history', making them unsuitable for anything BUT instantaneous services like file transfer and Instant Messaging.

    But why not a P2P, distributed forum, for instance. The forum database itself would be distributed (with a statistically appropriate level of redundancy/duplication) across storage on individual users machines. HDD storage has nev

  • Nothing is ever "fully decentralized" until the internet itself is a giant mesh network.

  • Well, not exactly [slashdot.org]

    I'm expecting something like this to topple Facebook.

    With a terabyte of storage on a handheld device and a local application, you could replicate FB's service without the ads, limitations and privacy issues.

    My phone is about to catch on fire! It is actually uncomfortably hot to the touch running the twister server -- some sort of CPU usage regulation would be nice. Love the idea.
