Understanding Blockchain and Ethereum Technology

This beginner’s section of our Blockchain Hub introduces what blockchain technology is and how it works, what Ethereum is and how to use it, as well as covering other important topics such as wallets, nodes, mining, validation, cryptography, smart contracts, storage, messaging and more.

If you’re completely new to blockchain, it’s worth starting with our article on what blockchain is, how it works, and why it’s so popular. The article explains the concepts behind blockchain technology with a simple example that’s valid for most cryptocurrencies currently in circulation.

You’ve no doubt heard of encryption, but do you know what it actually is and how it works? We also take a deep dive into cryptography, taking you back to the basics and explaining encryption, describing the different types, and demonstrating algorithm examples, all in a beginner-friendly way. If you’ve ever wanted to understand this but it seemed too complicated, you’ll love this post.

With all the excitement surrounding blockchain, it’s being used in a lot of ways it probably shouldn’t be. To get a realistic idea of what blockchain really should be used for, check out our guide to the top nine uses for blockchain. This will give you an idea of the long-term viability of blockchain and whether or not it’s actually useful for a particular purpose.

Next, you might like to learn about some of the essential elements involved with cryptocurrencies. For example, our article on hardware wallets delves into how wallets work and why they’re the most secure way to store cryptocurrency. You can also find out what a Bitcoin node is, while also learning the difference between mining and validation. And it’s also worth reading about efforts aimed at solving cryptocurrency scalability issues.

We also cover Ethereum in a lot of detail, starting with an introduction to Ethereum that shows its differences from and advantages over Bitcoin.

Then we go on to cover a lot of Ethereum-related topics, such as:

We also stand three Bitcoin alternatives side by side, comparing Ethereum with Cardano and NEO. Rather than looking at the platform as a cryptocurrency, this article looks at them from the more interesting technology perspective.
