Everything You Wanted To Know About Blockchains but were too afraid to ask

Ah, blockchains.

Kind of a big deal. You’d have to be a total square not to have heard about them. Me? I’ve got eight.

Often over-complicated, over-mysticised, over-singularised (I don’t even know what the right word for it is, but people say The Blockchain a lot). What are they? Join me for a rough tour from the ground up and I’ll try to make sure you leave here knowing the answer to one question:

What are people talking about when they talk about blockchains?

There’s a lot to cover, so it’s actually going to come in two parts. This, the first, will look at the data structures known as blockchains and their properties, along with any other bits and pieces you need to make sense of them.

The second part will apply what you’ve learnt to the practical and widespread applications of blockchains to power distributed ledgers, cryptocurrencies such as Bitcoin and Litecoin and smart-contract based chains like Etherium.
