| I'm Launching the First Truly Decentralized Private Marketplace [x-post from r/cryptocurrency] Posted: 09 Feb 2020 10:53 AM PST Hey everyone, Posting this here since there was a lively discussion related to the cs/engineering principles of the system on the r/cryptocurrency thread. This sub will probably be particularly interested in the paper on the system, which describes how the system works from a technical standpoint. I've been working for almost a year now on a platform I call the Ultranet that I'm planning on launching in three weeks on February 25th at 12pm Pacific Time (signup here to be notified). It's a marketplace platform that is fully-decentralized, private, and censorship-resistant. It works by having each user who runs the software download and store a cryptographically-secured copy of all of the listings, orders, ratings, and all other marketplace data through a concept I introduce in the paper called a "block pool." This means that as long as a single node somewhere in the world is running the Ultranet software, all data, including all listings and all reputation data, will be preserved. This is in stark contrast to virtually all platforms that exist today, which are subject to censorship of listings and/or outright take-down, the latter of which results in all reputation data being lost. Moreover, the Ultranet achieves censorship-resistance and privacy (it's pseudo-anonymous like Bitcoin) while maintaining feature parity and user experience parity with existing centralized marketplaces. It also introduces Ultra, a hyper-deflationary cryptocurrency that is burned every time an order is placed on the system and by merchants in order to promote their listings, resulting in increasing scarcity over time (i.e. hyper-deflation). Importantly, the use of a native cryptocurrency allows the value of the network to accrue to its users rather than a privileged few, while also giving people an incentive to use the system early on (thus helping to solve the "platform chicken and egg problem"). Finally, the software has a built-in fully-decentralized exchange mechanism I introduce in the paper called "interchange" that allows users to purchase Ultra using Bitcoin or Monero without any third parties involved, along with a fully-decentralized end-to-end encrypted messaging platform. I know it's only natural for people to be skeptical when reading a post like this, but I worked really hard on this because I really believe that the direction society is headed under the dominance of "surveillance capitalism" needs to be challenged somehow, and because I thought all of the existing attempts at disrupting things weren't sufficient. As such, having invested a lot of time and energy into trying to engineer a better way, I think the Ultranet and the concepts I introduce in the paper and in the software itself can at least serve as a guide to get us started down a serious path toward a more open and more democratic platform ecosystem. I'm launching the Ultranet in three weeks on February 25th at 12pm Pacific Time, at which point I'm going to make the software available for download on the ultranet.one website. I was going to wait until then to make my first post, but I thought publicizing it a bit before I release the final version of the software could give me a chance to address any last-minute concerns people might have about the first iteration (which is why I'm also releasing the code today; see below). In the meantime, if you want to learn more about the platform, below are some resources:
Thanks, and for anyone who reads this far just know that it means a lot to me that you are considering my work. [link] [comments]  |

| Posted: 09 Feb 2020 07:03 PM PST i'm doing a science fair project where i pentest personal health monitoring devices. i'm presenting it at the fair in the upcoming week but was wondering if it's inappropriate to name the company and model of the devices i tested?? i didn't notify them or anything but it's not being officially published either. what's the field standard for this??

| Posted: 09 Feb 2020 10:23 PM PST I have implemented a very simple but robust implementation of the Golomb-Rice coding. To understand my motivation, see the minimalist data compressor that is based on this. The implementation works well. The intent is to make it more elegant, concise, and possibly faster. Any suggestions for improvement or constructive criticism are welcome. Since the code a bit long, I posted it here: https://codereview.stackexchange.com/questions/236965/minimalist-golomb-rice-coder [link] [comments]  |
| Computer Science Education Survey Posted: 09 Feb 2020 05:02 PM PST Hi, I am working on a survey project for school on different ways to learn computer science. If anyone would be willing to help fill the survey out (only will take 3 minutes maximum), I would really appreciate it! The link to the actual survey is in the confirmation message once you submit the first form. Here's the link: https://forms.gle/mYLStLiu3XxFiHK99 [link] [comments]  |
