What Is Cryptocurrency?

If you've been following the news, chances are you've noticed that there's a lot of buzz surrounding cryptocurrencies, and more specifically, Bitcoin. Today, most people have heard of cryptocurrencies, which have recently become an international phenomenon due to the rapid increase in the value of Bitcoin. Most lay people, and even many bankers, scientists, consultants, and developers, have very little knowledge pertaining to cryptocurrencies and how they function. While most people don't have a good understanding of cryptocurrencies or how they work, they are aware of the growing importance of these digital currencies on the global stage. If you have no idea what cryptocurrencies are, this in-depth guide will teach you the basics.

What Is Cryptocurrency?

A cryptocurrency refers to a virtual or digital currency that is designed to work as a system of exchange. As you may have been able to guess by the name, cryptography is a major aspect of cryptocurrency. Digital currency, such as Bitcoin, relies on cryptography to verify and secure transactions. Cryptography is also used to regulate the generation of new units of a certain type of cryptocurrency. Cryptocurrencies are finite entries in a database. These entries can only be changed if, and only if, certain requirements are met.

What Is the History of Cryptocurrency?

During the technology boom of the 1990's, there were many attempts to create a digital currency. DigiCash, Flooz, and Beenz are a few examples of the digital currency systems that appeared on the market but ultimately failed. There were a multitude of underlying reasons for the failure of these digital currency systems. Some of these reasons included financial problems, fraud, and disagreements between the employees and bosses.

Many of these systems relied on a Trusted Third Party approach. This approach involved having the companies behind the systems verify and facilitate digital currency transactions. Since all of these systems ultimately failed, many people viewed the idea of digital currency as a lost cause.

In 2009, a group of programmers introduced Bitcoin as a bitcoin. The alias of the group of programmers was Satoshi Nakamoto. Behind this alias, the programmers described Bitcoin as a "peer-to-peer electronic cash system." The decentralization of this system meant that no servers were involved. The system lacked a central controlling authority. This concept is very similar to peer-to-peer networks when it comes to file sharing.

When it comes to payment networks, double-spending is one of the most vital problems that need to be solved. Double-spending refers to when an individual spends the same amount of currency twice. In the past, systems attempted to solve this issue by relying on a trusted third party in the form of a central server. The central server was responsible for keeping records of transactions and balances. However, the flaw of this method was that a single authority was in control of all the funds as well as the personal details of those making transactions.

Since Bitcoin is a decentralized network, all participants share the responsibility of this job. Blockchain, which is a public ledger of every transaction ever, makes this possible. Blockchain is available to everyone, which means anyone in the network is able to see the balance of any account.

Every transaction is stored in file, which contains the public keys of the recipient and sender as well as the number of Bitcoins transferred. The sender needs to sign off the transaction with their private key. Once the transaction is confirmed, it is broadcasted to the network. Only miners are able to confirm transactions in a cryptocurrency network. Miners do so by solving cryptographic puzzles. When a miner solves a cryptographic puzzles and marks the transaction as legitimate, the transactions are spread across the cryptocurrency network. All nodes add the transaction to their database.

Once confirmed, a transaction is irreversible and unforgettable. For their efforts, the miner receives the transaction fees and a reward.

Cryptocurrency networks depend on the consensus of every participant when it comes to the legitimacy of transactions and balances. If the nodes in a network were to disagree on just one balance, the system would fall apart. Fortunately, there are many rules that are built into the network to reduce the chances of this occurring. Cryptocurriences get their name from the fact that strong cryptography is used for the consensus-keeping process. All of these factors make blind trust and third parties unnecessary when it comes to cryptocurrencies.
