Understand what cryptocurrencies are and how they work with this helpful guide

Cryptocurrencies, despite being around for a decade, are still surrounded by mystery and misunderstanding.

Their history stems from cryptography, which since the 1960s has evolved at a rapid pace thanks to the advent of computers.

In 2008, an anonymous figure going by the name of Satoshi Nakamoto released the Bitcoin white paper, which built on the works of prominent cryptographers such as David Chaum, Nick Szabo, and Adam Back.

Since then, thousands of cryptocurrencies have been created and a new burgeoning industry is being developed. Whilst much of the focus often relates to price, there are underlying philosophical, ideological, and technological issues that cryptocurrencies are attempting to solve.

What is cryptocurrency?

A cryptocurrency is a digital currency that uses cryptography to secure and verify its transactions, recording them in a decentralised and immutable ledger known as a blockchain. They can be used as a medium of exchange or a store of value, and are traded on many exchanges around the world.

They can be viewed as an alternative to standard national currencies, and they have value and are traded in a similar way on exchanges. However, cryptocurrencies have no physical form that you can take out of cash machines, for example, and exist only in the digital space. Digital cryptocurrency “coins” can be bought, sold, and converted back to fiat money on specialised cryptocurrency exchanges. There are hundreds of cryptocurrency exchanges including the like of Gemini, Independent Reserve and Coinbase, as detailed here by Crypto Head.

Cryptocurrencies operate independently from banks and act as an alternative form of payment to cash and credit cards. As such, it’s becoming increasingly popular in countries where banking institutions are unstable, as people would rather have full control of their money in a digital space rather than rely on the banks to keep their money safe. Another common example is using cryptocurrencies to send money abroad to avoid large processing fees from banks.

Because cryptocurrency is still maturing however, the markets are much more volatile than standard foreign exchange markets, and so cryptocurrencies are currently more often used for investment purposes.

A brief history of cryptocurrency

Cryptocurrencies first emerged with the release of Satoshi Nakamoto’s Bitcoin white paper on a cryptography mailing list in 2008. Although it was quite technical, this outlined a clear vision of a “purely peer-to-peer version of electronic cash (allowing) online payments to be sent directly from one party to another without going through a financial institution”. In 2009, the software went live.

In the last nine years, over 2,500 cryptocurrencies have appeared—a number which will either increase or decrease depending on your views on cryptocurrency.

Cryptocurrencies can be divided into two categories: those that are supported by their own blockchains, like Ethereum and Bitcoin, and those built on top of other blockchains, also known as tokens.

Blockchain—the technology powering cryptocurrency

When talking about cryptocurrencies and what they are, it’s important to understand the concept of blockchain technology. Blockchain is the underlying technology powering cryptocurrencies. It’s used to create, update, and maintain a decentralised, trusted ledger of transactions which occur within a network. This network is made up of independently-owned nodes that use a cryptographic protocol to validate transactions in a cryptocurrency.

The protocol rewards accuracy in a way that ensures the data entered into the ledger cannot be wrong or subject to changes. It is immutable, secure, and completely transparent. Blockchain technology makes it possible to trust the information kept on that ledger without having to rely on a central institution like a bank. A lot of the hype surrounding cryptos comes mostly from the fact that virtually our entire economy does, in fact, rely on centralised institutions which guarantee trust in the whole system.

Analysts look at cryptos and recognise in them the potential to revolutionise the banking and finance industries. However, it’s important to remember these sectors have existed for centuries. In that time, banks have changed, but they’ve primarily remained in control of their own destiny.

To this end, large financial institutions have been keen to understand blockchain-powered cryptocurrencies. They have poured millions into research and development to understand and integrate the underlying technology, hoping this will allow them to stay ahead of the curve.

Tokens

While Ethereum is an independent cryptocurrency with its own native token, Ether (ETH), ERC-20 tokens are tokens that would not exist without Ethereum’s platform.

A token is merely a unit of value issued by an organisation, accepted by a community, and supported by an existing blockchain. That organisation sets it up within a particular business model to incentivise user interaction by distributing rewards among its network’s participants. These tokens have many uses, but are most commonly divided into security tokens and utility tokeinns.

Security tokens are similar to traditional company shares since they derive their value from a tradable external asset. A utility token grants access to a company’s future product or service before it can be delivered – much like when a bookstore lets customers pre-order a book that hasn’t come out yet.

Important distinctions

The best method of identifying the difference between an independent cryptocurrency and a token is to ask the question: Is this crypto independent from other platforms or does a pre-existing blockchain support it?

An independent cryptocurrency uses its own blockchain while a token is merely a cryptocurrency built on top of another pre-existing blockchain. Tokens are a subset of all cryptocurrencies.

Within the long list of independent cryptocurrencies, there is another difference. They can either be Bitcoin-based blockchains such as Dash or Litecoin or they can have their own native blockchains like Ripple or Ethereum.

All cryptos in these two categories can also be called alternative coins. Altcoins get their name from being alternatives to the original cryptocurrency: Bitcoin.
