Читать книгу Cryptocurrency All-in-One For Dummies - Peter Kent, Kiana Danial - Страница 124

Private blockchains hold the promise of having both the benefits of a private database and the security of blockchains. The idea is most appealing for two reasons:

 Private blockchains are great for developers because they allow them to test ideas without using cryptocurrency. The developers’ ideas can remain a secret as well, because the data has not been published publicly.

 Large institutions can capitalize on the security and permanence of blockchain technology without their transactions being public the way they are in traditional blockchains.

Most of this minibook assumes you’re just finding out about blockchain for the first time and have little to no programming skills, but this section requires some knowledge of GitHub, Docker, and how to use your computer’s terminal. If you need a quick recap on coding before you dive in, Coding For Dummies by Nikhil Abraham (John Wiley & Sons, Inc.) provides a great overview on coding for nontechnical people. If you don’t plan to ever be hands-on with blockchain technology, you might want to skip the rest of this chapter.

In this section, you dive into building your first blockchain. You build it in two steps. The first step is to prepare your computer to create your private blockchain. Don’t worry — it’s made easier with tools from Docker and work that has been done by talented developers on GitHub. The second step is building your blockchain inside your Docker terminal.
