Use Vue.js To Generate Cold Storage Paper Wallets For DigiByte DGB Coins

To continue on my technical journey of cryptocurrency coin management, I figured it would be a good idea to share how to create a paper wallet for DigiByte DGB coins. A few weeks back I had written a tutorial titled, Generate Cold Storage Paper Wallets for Ripple XRP Coins with Angular, but we all know Ripple isn’t the only technology on the block.

In case you’re unfamiliar with paper wallets, they are nothing more than printouts that contain your private and public key information. It is separated from the internet and the paper wallets can be placed in a cold storage location like a locked safe or a bank.

We’re going to see how to use JavaScript and the Vue.js framework to generate DigiByte DGB wallet information that includes QR codes for easy scanning.

Write Blog Articles In Markdown On The Polyglot Developer

As you may or may not know, The Polyglot Developer is happy to accept guest contributions from the developer community. To find out more, check out the article titled, Write Guest Articles on The Polyglot Developer Blog. With that said, I’ve been receiving a lot of questions regarding Markdown, the format in which these blog articles are crafted.

The Polyglot Developer uses Hugo which is similar to Jekyll in the sense that articles are written in Markdown and then built into HTML. Don’t worry, Markdown is not bad and you’ll see how much more convenient it is than writing in other formats.

We’re going to get a quick look at producing content in Markdown so it can be published on the web.

Containerization with Docker by Example Released

I am pleased to announce that Containerization with Docker by Example, a course I’ve been working on for a while, has been published to the popular Udemy education network.

This course, is the fifth course that I’ve released and the first that hasn’t been on the topic of mobile application development.

Encrypt And Decrypt Data In Node.js With The Crypto Library

As you’ve probably noticed from the previous few articles, I’ve been doing a lot of development around cryptocurrency wallets using Node.js. Up until now, I’ve only been writing about interacting with different currencies. However, I haven’t discussed how to safely store your wallet information.

When it comes to storing anything sensitive, whether it be cryptocurrency secrets or something else, you must do so safely and securely. For example, the data must be encrypted at rest and decrypted when used.

We’re going to see how to encrypt data with a passphrase using Node.js and decrypt it using that same passphrase when necessary.

Use A Raspberry Pi And A CPU Miner To Mine Altcoins

I’m a big fan, and hoarder, of Raspberry Pi devices. If you’ve seen my previous Raspberry Pi tutorials, you’ll know I like using them for hardware and software projects. These microcomputers use very little energy and have decent processors and memory, making them great for a diverse set of projects.

With blockchain and cryptocurrencies on the rise, Raspberry Pi devices become great for getting familiar with concepts such as wallets, mining, and synchronized nodes.

We’re going to see how to mine Altcoins with a Raspberry Pi and a popular CPU miner.

Create A Cross-Platform Desktop DigiByte DGB Wallet With Angular And Electron

A few weeks back I had written an article titled, Send And Manage DigiByte DGB Coins With Node.js, which had explained how to interact with DigiByte coins via Node.js and the CLI. We saw how to keep track of a wallet, compare against the market value, and send DGB to other wallets. The catch here was that it was all CLI based and not particularly user friendly.

A popular solution towards adding a GUI to a Node.js application comes in the flavor of Electron. With Electron you’re essentially packaging a web application that can interact with native platform APIs.

Since I’m a fan of Angular, we’re going to see how to create a fancy DigiByte wallet using Electron, Node.js, and Angular.

Mine Bitcoin And Other Cryptocurrency Coins With A CPU Miner And Docker

So you’ve been doing a lot of research around the blockchain and the various cryptocurrencies. Don’t worry, I’ve been doing a lot of the same research. There is so much in the news and on social media around this subject, it would be a good idea to educate yourself.

When it comes to cryptocurrencies, there are a lot of people trying to mine it rather than buy it. Depending on the type of currency, it could be near impossible to mine or very easy. Take Bitcoin for example. Bitcoin is one of the most difficult coins to mine, while others such as DigiByte are much easier. That’s not to say the easier coins won’t become more difficult in the future.

So how do you get started with mining?

I use a Mac. If you’re a Mac owner and you try to find a mining tool online, you’re going to struggle because most are for Windows or Linux. We’re going to see how to leverage Docker to mine via a Linux container on any platform.
