Create A Bitcoin Hardware Wallet With Golang And A Raspberry Pi Zero

Over the past month or so, in my free time, I’ve been working towards creating an affordable hardware wallet for various cryptocurrencies such as Bitcoin. Right now many cryptocurrency enthusiasts are using the Ledger Nano S hardware wallet, but those are very expensive and rarely in supply.

I own several Raspberry Pi Zero and thought it would be a perfect opportunity to take what I know about Raspberry Pi and Golang to create a wallet for a fraction of the price as the industry leading wallets.

We’re going to see how to create a hardware wallet, which I’m calling the Open Ledger Micro, using Golang and a Raspberry Pi Zero.

Create And Sign Bitcoin Transactions With Golang

About a month ago I had written about creating and importing private keys as well as generating public addresses for Bitcoin and several other cryptocurrencies using the Go programming language. This previous tutorial had more of an emphasis on creating cryptocurrency wallets with Golang than anything.

The next step in making Bitcoin and other cryptocurrencies useful is to be able to transfer or send them to other people. Sending Bitcoin is part of a process known as creating and broadcasting a transaction.

While we won’t be actually broadcasting a transaction in this tutorial, we’re going to figure out how to create an unsigned transaction, then sign it, using the Go programming language and some popular Bitcoin packages.

Generate Cryptocurrency Private Keys And Public Addresses With Golang

Over the past month or so I’ve demonstrated how to generate address information for a variety of cryptocurrency Altcoins using technologies like Node.js, Vue.js, and Angular. The thing about my previous tutorials are that they all used the JavaScript stack in some sense. What if we wanted to adventure into other technologies like Golang?

The process for generating key and address information for Bitcoin and popular Altcoins is pretty much the same. In reality, the difference is defined by the private key and public key prefix information, typically associated to a network.

We’re going to see how to generate and import private keys for a variety of cryptocurrency coins as well as their addresses using the Go programming language.

Use Angular To Create A Cross-Platform Stellar XLM Desktop Wallet

With Android and iOS so obtainable and development so easy, people often forget the importance of desktop applications. I have a phone and tablet, but I depend on my desktop applications much more. However, the development of these applications are not difficult.

With frameworks like Electron, developers can create cross-platform desktop applications with JavaScript and HTML. Take the example I wrote about previously in the article titled, Create a Cross-Platform Desktop DigiByte DGB Wallet with Angular and Electron. I demonstrated how to leverage a very popular framework to create a cryptocurrency wallet.

DigiByte isn’t the only popular blockchain on the internet. I’ve also been looking into Stellar because of all the buzz it has been receiving from popular companies like Stripe.

We’re going to see how to create a Stellar XLM wallet for Mac, Windows, and Linux using Angular and Electron.

Create Paper Wallets For Stellar XLM Coins With Angular

Continuing down my adventure of learning about and investing in various cryptocurrencies, I thought I’d explore Stellar, which is what I understand to be, a competitor to Ripple. If you’ve been keeping up, you’ll remember that I had written about creating a Ripple XRP paper wallet in a tutorial titled, Generate Cold Storage Paper Wallets for Ripple XRP Coins with Angular.

In this tutorial, we’re going to see how to accomplish the same task of generating a cold storage paper wallet with Angular, but this time we’ll be doing it for Stellar XLM coins.

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.

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.
