  • Open-Source Platform Lets Users Build Their Own Blockchain in Under 10 Min

    An out-of-the-box solution says it enables anyone, even with no experience, to build their own blockchain in under 10 minutes.
    According to Nuls, businesses are going through a similar evolution as they did with the early internet, when every company wanted their own website: They now want their own blockchain. And although these firms may not fully understand how to deploy blockchain technology, they are aware of how their business may benefit from it.
    Nuls aims is to “dismantle some of the biggest barriers” that are stopping individuals and companies of all sizes from creating their own blockchains. Hurdles for adoption include the need to ensure that networks are fully secure and the sheer cost of bringing them to fruition. On top of this, it can be an incredibly time-consuming process — not least because there aren’t enough skilled developers to keep on top of demand.

  • Open-Source Tool Lets Anyone Experiment With Cryptocurrency Blockchains

    Blockchain technology records information to a ledger shared between thousands of nodes. In the technology’s purest form, those nodes are not controlled by any central authority, and information cannot be changed once written to the ledger. Because of the security and autonomy this technology offers (in theory at least), blockchains now underpin many popular cryptocurrencies such as Bitcoin.

    But as Kazuyuki Shudo, an associate professor at the Tokyo Institute of Technology, points out, "It has been nearly impossible to test improvements on real-world blockchain networks, because that would mean having to update the software of all the thousands of nodes on a network."

  • Blockchain founders raised $822m by Q2 – with enterprises focused on open source

    According to the latest State of Blockchains report from Outlier Ventures, blockchain startups raised $822 million by Q2 – but the ecosystem continues to lag behind the 2017 and early 2018 peak.

    $822m was raised across 279 deals over the second quarter of 2019, with more than half of them being seed stage deals indicating continued fresh talent into the space.

    Yet while the numbers may be lower, the scope is much more advanced – particularly with how enterprises are associating with the technology.

    The report explores case studies which will be familiar to readers of this publication. Last month The Block reported that retailer Target had posted a job advert for a blockchain engineer, with the right candidate being able to contribute to ConsenSource, a certificate registry blockchain application based on Hyperledger Sawtooth. The company’s interest in blockchain has been noted, working with agribusiness provider Cargill on a Hyperledger-built project around the supply chain.

    [...]

    The Block spoke with Burke at the Blockchain Expo Global event in London around the data and platform monopolies which exist today.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
