  • Eric Voorhees compares trust in politicians to open source code

    Early Bitcoin advocate Eric Voorhees has said that “by holding Bitcoin, you are ultimately trusting open source code” in a dig at political systems all around the world.

    Political trust levels are currently plummeting. In countries like Venezuela, we can see political turmoil spilling into the lives of citizens who are now fleeing in droves across the borders. Also highly ranked on the list of politically unstable countries are Brazil, Ukraine, and Turkey, who have all seen major surprises in their recent elections.

  • Open source DEX protocol Loopring adds cryptography to technology mix

    Brecht Devos, protocol development lead, Loopring, said, “A number of hurdles have delayed the adoption of DEXs to date, including, but not limited to, a lack of scalability. However, there’s no doubting that decentralized exchanges represent the future of crypto trading, addressing, as they do, the multitudinous issues faced by users of centralized exchanges in their day-to-day transactions, such as the risk of hacks, personal data leaks, or blocked funds.

  • Ethereum Core Developers Debate Benefits of More Frequent Hard Forks

    A group of ethereum’s veteran open-source developers discussed the subject in a bi-weekly meeting Friday, wherein they aired the possibility that system-wide upgrades, also called hard forks, to the software could be enacted as often as every three months.

    Wanting to “check the temperature,” the developer asking the question explained that certain upcoming ethereum improvement proposals (EIPs) such as state rents would require multiple upgrades sequentially spaced out for full effect.

  • Digital Asset open sources ISDA derivatives blockchain code

    In February the International Swaps and Derivatives Association (ISDA) released version two of its Common Domain Model (CDM) which aims to standardize the coding of derivatives trade events and processes. Today Digital Asset announced that it’s working with ISDA on an open source code library that implements the CDM in Digital Asset’s smart contracting language DAML.

    The aim of implementing the CDM across the derivatives sector is to save money, and the savings could be as much as $2.5 billion. Last year Ledger Insights spoke to Lee Braine from the Chief Technology Office at Barclays about ISDA’s new standard. “Across the post-trade derivatives industry, there is infrastructure deployed that is too complex for its current purpose. And the proposal is analogous to pressing a technology ‘reset button’ allowing you to go back and radically simplify the nature of that infrastructure.”

  • Blockchain Set to Revolutionize the Open Source Movement

    It is evident that open source has transformed the current world. Developers rely extensively on open source software since it dominates the developer infrastructure. From the many operating systems like Linux in the cloud to databases like MongoDB, MySQL, and Redis, open source is there. Also, the movement dominates the programming languages themselves like Python, C, Javascript, PHP, and Java.

    Open source is also good for the consumers featuring in their phones, Android, to their method of web access like Firefox and Chrome. Hence, it makes technology more accessible and open which enables anyone to build anything.

  • IOTA To Replace Its Coordinator With An Open Source Version Of Coordinator On Mainnet

    The first open source ledger built to power the future of internet of things, IOTA is in a lot of use previously, right from waste management to green energy solutions. And now with the development of Coordicide, the platform may get a lot more transparent.

    Coordicide is actually the effort of removing the Coordinator from the IOTA networks and its research stage. For developing the Coordicide, IOTA is making the inner workings of the current network set-up fully transparent. IOTA aims to do this with an open-sourced version of the Coordinator running on Mainnet.

  • Altcoin News: IOTA to Replace Coordinator With Open Source Version

    IOTA’s technology has been put to a lot of use in the last few months, from waste management to green energy solutions. Now, it is about to become much more transparent with the development of the Coordicide.

    In an April 8, 2019 blog post, the firm gave some more insight into the development of Coordicide and the changes that will be made in that regard in the near future. First, it was explained what exactly the Coordicide is. According to the post, it is a deliberate effort to remove the Coordinator from the IOTA networks and is its research stage.

    [...]

    This open source version of the coordinator is called the Compass and was initially released some months back and allowed the opening of a private network, running of tests, and development PoCs. So far, the Compass has been tested on the spamnet and devnet and is now ready to be moved to the mainnet. IOTA has stated that using an open source version of the coordinator will make the network more transparent while improving it.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
