In this post we will take a closer look at the magic of cryptography and how it features in Bitcoin.
Bitcoin begins with public key cryptography
As I’ve touched on in my previous posts, the Bitcoin protocol is essentially a record of transactions between addresses. For simplicities sake you can think of an address as being akin to an online bank account. The Bitcoin ledger contains records of the coins that each address has sent and received.
But what actually is an address? Public key cryptography was published in the 1970s and provides a method for asynchronous encryption and decryption of information.
What on earth does that mean?
So far, we’ve covered an introduction to crypto currency and the key innovations which inspired the creation of Bitcoin.
Now let’s lift up the hood and take a peek at Bitcoin’s delicates.
Welcome back reader.
So you’ve read about the crazy new world of crypto currency and want to understand where it all began?
The tale of Bitcoin is long and winding, it all begins with an underground online community which emerged in the early nineties on a usenet mailing list.
Hello reader… yes, you. Come closer and I’ll tell you the story of one of the most captivating inventions of the 21st century… crypto currency.
In the simplest terms, crypto currency can be thought of as digital money. That is, money which is generated and governed by computers over the internet.
In reality however, the story is far more interesting and complex than can be conveyed in a single sentence. Indeed the topic will be the focus of the majority of the posts on this site.
This post is the first of an introductory series which will take a look into the origin and mechanics of crypto currency.
