A lot of people have been asking about cryptocurrencies lately. The term cryptocurrency is used for any digital currency that uses cryptography to make sure that transactions are valid and irreversible.

Let’s start from the beginning. A digital currency can be defined as a currency that only exists digitally, that usually has no central issuing or regulating authority but instead uses a decentralized system to record transactions and manage the issuance of new units, and that relies on cryptography to prevent counterfeiting and fraudulent transactions.

All cryptocurrencies are digital currencies, but not all digital currencies are cryptocurrencies. Just like we have different types of currencies, fiat money, digitized fiat money (digital money) and cryptocurrencies, there are different types of digital currencies: non-cryptocurrencies and cryptocurrencies.

Non-Cryptocurrency Digital Currencies

Non-cryptocurrency digital currencies (or traditional digital currencies) are all forms of money that are solely used online (some examples include airline miles and game credits). These forms of money do not use encryption techniques to verify funds nor do they use a decentralized network to store transaction data. If you are familiar with PayPal or Debit/Credit cards then you already know about this type of digital currency. These forms of money can be easily counterfeited by anyone with a computer (as

Cryptocurrencies are a relatively new and inherently disruptive technology with the potential to change how business is done. The market is still at an early stage with lots of volatility, hype and uncertainty. In this blog I want to break down some of the technical concepts behind cryptocurrencies.

You can think about cryptocurrencies as a kind of digital money that has been designed to be secure and, in many cases, anonymous. Cryptocurrencies use decentralised technology to let users make secure payments online without the need for a bank or credit card company.

They run on a distributed public ledger, called blockchain which records all transactions chronologically and publicly. It is maintained by a network of computers that are working together and they are incentivised through cryptocurrency tokens. This means that there is no central control over the cryptocurrency and it is instead managed by its users at large.

What are Cryptocurrencies?

A cryptocurrency is a digital or virtual currency that uses cryptography for security. A cryptocurrency is difficult to counterfeit because of this security feature. A defining feature of a cryptocurrency, and arguably its most endearing allure, is its organic nature; it is not issued by any central authority, rendering it theoretically immune to government interference or manipulation.

Bitcoin became the first decentralized cryptocurrency in 2009. Since then, numerous cryptocurrencies have been created. These are frequently called altcoins, as a blend of alternative coin. Bitcoin and its derivatives use decentralized control as opposed to centralized electronic money/centralized banking systems. The decentralized control is related to the use of bitcoin’s blockchain transaction database in the role of a distributed ledger.

Decentralized cryptocurrency is produced by the entire cryptocurrency system collectively, at a rate which is defined when the system is created and which is publicly known. In centralized banking

The first thing to know is that there are different kinds of cryptocurrencies. There are the ones that act as a medium of exchange and aim to become the digital equivalent of cash. Bitcoin, which is the most popular cryptocurrency, is one example.

And then there are the ones that act as a store of value — like gold — and aim to create digital scarcity. Two examples would be Zcash and Monero, which allow users to obscure who’s transacting with whom on their networks.

These two types are very different from each other and from what we’re used to in the real world, so let’s take a look at how they work.**

In the last few years, Bitcoin has been the talk of the town. It’s a digital currency that many people feel will change the way we use money in the future. In this article, we’re going to look at how digital currencies work and how they’re mined.

This is a complex topic, but I’ll try to be as easy-to-understand as possible.

In a nutshell…

Cryptocurrencies are “digital money” that use cryptography (a form of secret code) to secure transactions. Cryptocurrencies are also known as virtual currencies because they exist only in computer code.

Bitcoin is the most popular cryptocurrency and was created by a person (or group) with the name Satoshi Nakamoto. The Bitcoin network is peer-to-peer, so there is no central authority (like a bank). Instead, every single computer on the network records every single transaction done on Bitcoin. This makes it easy to trace where Bitcoins came from and how much they are worth at any given time.

The Bitcoin network has rules just like any other system does (i.e., you can’t send someone double what you owe them). These rules make it harder for someone to steal Bitcoins from

Over the past several years, public interest in cryptocurrencies has increased dramatically. Given the prices on popular cryptocurrencies like Bitcoin and Ether, it’s hard to believe that these cryptocurrencies have been around for nearly a decade. It’s also hard to believe that there is still a lot of confusion as to what cryptocurrencies are, how they work, and why they even exist in the first place.

In this blog, we’ll answer all of those questions and more. We’ll explain what cryptocurrencies are, how they work, and give you a brief history of their creation and evolution.

What Is Money?

The unit of value that we use to measure how much an item costs is called money.1 We use money because it is easier than bartering for goods individually with other people who have items we want. Barter systems can be inconvenient because you need items that someone else wants in order to trade for items that you want. If I don’t have anything you want, why would you trade me your good or service? Without money, we would need every transaction to be an even trade of goods or services between two people (direct barter). This would increase transaction costs (time spent negotiating), making it harder for individuals to acquire the goods and services they desire. In fact, without

The value of digital currencies is less than the value of their underlying technologies. The technology that underlies digital currencies like bitcoin is one of the Internet’s greatest gifts to humanity. It allows people who do not know or trust each other to create a record of who owns what that will compel the assent of everyone concerned. It is a very useful tool.

Digital currencies are just databases that keep track of how much money everyone has. Normally, banks are in charge of updating this information and telling everyone who has how much. And normally, people trust banks to do this honestly.

But what if you didn’t have to trust anyone? What if you could be your own bank? That’s what bitcoin lets you do. If you have some bitcoins, they are recorded as belonging to you in a file somewhere – a file that people can only change by making new transactions that point to the new state of who owns what bitcoins:
