In the previous article, I have shared about why you should seriously look into cryptocurrency in 2018 and beyond.

I have explained about what cryptocurrency is and the many types of cryptocurrencies currently available.

Now, let’s take a deeper look on how this thing called cryptocurrency actually works.

The reason why cryptocurrencies are such in demand right now is because Satoshi Nakamoto successfully found a way to build a decentralized digital cash system. What is a decentralized cash system?

A decentralized system means the network is powered by its users without having any third party, central authority or middleman controlling it. Not the central bank or the government has power over this system.

The problem with a centralized network in a payment system is the so called “double spending”. Double spending happens when one entity spends the same amount twice. For instance, when you purchase things online, you have to incur for unnecessary and expensive transaction fees. Usually, this is done by a central server that keeps track of your balances.

This is most commonly known as the Blockchain Technology. Cryptocurrency is derived from the word “Cryptography”, which refers to the consensus-keeping process secured by strong cryptography.

Blockchain technology functions in managing and maintaining a growing set of data blocks, and this is by using the decentralized or known as the P2P (Peer to Peer) network. In blockchain, once a piece of data is recorded it cannot be edited or changed.

To put it in simpler terms, it enables you to send a gold coin via email. The P2P network is a consensus network, which allows a new payment system and the transactions of new digital money.

Let’s illustrate an example. Cryptocurrency like Bitcoin consists of its own network of peers. Every peer has a record of the complete history of all transactions as well as the balance of every account.

By the end of every transaction and upon confirmation, the transaction is known almost immediately by the whole network. A transaction includes a process where A gives X amount of Bitcoins to B, and is signed by A’s private key. After signed, a transaction is broadcasted in the network. The information is sent from one peer to every other peer on the network.

Confirmation is a critical stage in the cryptocurrency system. Confirmation is everything. When the transaction is not confirmed, it has the possibility of being hacked and forged.

When a transaction is confirmed, it is set in stone. It can’t be reversed, it is impossible to be hacked, it is not forgeable as it is part of a permanent record of the historical transaction: The Blockchain.

The blockchain can be likened to an online ledger, where all transactions are recorded and made visible to the whole network.

This comes to show that cryptocurrencies are not secured by people or trust, but by complex mathematical equations. It is very secure and it’s highly unlikely that the address of a currency is compromised.

Only miners are able to confirm a transaction. This is their role in the cryptocurrency network. They record transactions, verify them and disperse the transactional information in the network.

For every completed transaction monitored and facilitated by the miners, they are rewarded with a token of cryptocurrency, for instance with Bitcoins.

Since miners play a major role in the cryptocurrency system, let’s look at their role in more detail.

What Are Miners Doing?

First and foremost, principally anyone can be miner. Miners are needed because of the nature of the decentralized network where they have no authority to delegate tasks and the cryptocurrency needs some kind of system to prevent any form of network abuse.

For instance, a person may create thousands of peers and spread forged transactions. It will disrupt the system immediately.

In order for you to be a miner, you would need to solve a cryptologic puzzle which is a set of very complex mathematical questions set by Satoshi Nakamato himself. If you successfully solved the puzzle, as a miner you can build a block and add it to the blockchain.

The miner is also given permission to add a crypocurrency transaction to the system which automatically grants him a specific number of bitcoins. This is the only way to create valid bitcoins. Bitcoins can only be generated if a miner can solve a cryptographic puzzle. The level of difficulty increases with the amount of computer power the miners invest.

How Are The Cryptocurrencies Value Determined?

The value of cryptocurrencies are dependent on the market, where the prices of various cryptocurrencies vary a lot and is one of the most fluctuating and volatile markets to date.

The price of cryptocurrencies like any other products is dependent on demand and supply. If more people demands a particular currency and it is short in supply, then the value increases. More units are mined by miners to balance the flow. However, most currencies limit the supply of their tokens.

For instance the total amount of Bitcoin issued is only 21 million. Therefore Bitcoin’s supply will decrease in time and will reach its final number by 2140. It also explains why Bitcoin’s value is higher as compared to other cryptocurrencies.

Now you must be wondering, what is cryptocurrency used for?

Cryptocurrencies can be spent for different purposes and the best part is, all transactions are completed online. There are 3 different transactions that can be performed when using cryptocurrency as I have explained in the previous article:

  1. Bitcoin Trading
  2. Personal Spending
  3. Crowd Funding

Now, let’s take a look at each function a little deeper.

First, the Bitcoin trading.

Bitcoin trading can be very profitable for both professionals and beginners. The market is new, where arbitrage and margin trading is widely available.The currency’s high volatility has also played a major role in bringing new investors to the trading market.

Compared to other financial currencies, Bitcoin has very little barrier to entry. If you already own Bitcoin, no verification is required and you can start trading almost instantly. Moreover, Bitcoin is not fiat currency. This simply means the price is not related to the economy or policies of any single country.

And unlike stock markets, there are no official Bitcoin exchanges. Instead, hundreds of Bitcoin exchanges operate 24/7 around the world. Because of no official exchanges, this results in no official Bitcoin price where the currency is known for its rapid and frequent price movements.

Secondly is personal spending. You can use Bitcoin to purchase almost anything! From buying cars to travelling the world.

In December 2013, a Tesla model S was purchased for a reported 91.4bitcoins. The dealer, located in California continues to accept Bitcoin as a means of payment. They have since managed to sell a Lamborghini Gallardo for 216.8 Bitcoin.

You can also travel the world using Bitcoins! Just head to On 22nd November 2013, they announced that they would be the first online travelling agency accepting Bitcoin. You are able to purchase flights, hotels, car rentals and cruises. You can even book the whole package.

Cryptocurrency also provides the chance for you to give back to society. How? By crowd funding. You are able to be part of someone’s success story by donating to a crypto crowd funding project. Companies such as Lighthouse have built their crowd funding platform using Bitcoin.

The perks of donating through this system are you will not be charged for your donation and funds will not be released unless the project meets its criteria. You are also able to withdraw from the campaign before its completion.

You have complete control over the donation. Examples of successful funding campaigns are from Dogecoin, which includes campaigns run for Nascar driver Josh Wise.

I hope by now you have a pretty good understanding about how cryptocurrency works. In the next article, I will share about how you can begin investing and playing in the cryptocurrency game. Stay tune.
