A Beginner’s Guide to Understanding Cryptocurrency and their Underlying Blockchain Technology (Part 1)
Introduction
The cryptocurrency industry has generated substantial buzz and attention in the past decade. Many still perceive cryptocurrencies as a relatively new phenomenon however, their origins can be traced back to 2009 when the mysterious Satoshi Nakamoto released the groundbreaking Bitcoin White Paper. This industry has now surged to unprecedented heights, boasting a current total market cap of $1.17 trillion at the time of writing. The Bitcoin network has witnessed remarkable engagement, with 1.5 million active sender and receiver accounts on a daily basis. Glassnode, which is a prominent crypto analytics website, reports over a million Bitcoin wallets holding at least one Bitcoin, equivalent to approximately $30,000. Another leading blockchain, Ethereum, registers a staggering 110,000 new unique addresses daily, as per data from Ycharts.com, an Ethereum analytics platform. Beyond Bitcoin and Ethereum, a vast array of alternative coins, referred to as altcoins, circulate within the industry, each offering novel advancements or targeting untapped promising areas.
This is the first article in a three-part series that offers an introductory understanding of cryptocurrencies. In this article, I will delve into the concept of cryptocurrencies and explore their nature as a digital form of currency. I will shed light on the essential features that define cryptocurrencies, including decentralization, the utilization of blockchain technology, and the critical role of cryptographic security.

A cryptocurrency refers to a form of currency that lacks physical attributes and exists purely in the virtual realm. This should come as no surprise, given that a significant portion of today’s transactions are conducted digitally. For instance, when you visit a coffee shop like Starbucks and use your credit or debit card to make a purchase, the payment processor, such as MasterCard or Visa, engages in a series of communications with your bank and the merchant’s bank to complete the transaction. In this scenario, there is no physical exchange of tangible cash; instead, a simple accounting change occurs in the ledger, resulting in a deduction from your account balance and an increase in the merchant’s account. Cryptocurrencies operate similarly but with one crucial distinction: through decentralization, they eliminate intermediaries such as banks or payment processors.
Decentralization means that no single authority possesses control over the cryptocurrency or its network, unlike traditional forms of currency like the dollar or euro, which are governed by respective governments and central banks. Every transaction, from the earliest to the most recent, is recorded on the blockchain, acting as a transparent and immutable ledger accessible to all participants. Most Blockchains are transparent, providing visibility to all, and their immutability prevents any modifications, which is critical for fraud prevention and fostering trust among all participants. However, to facilitate private transactions, certain Blockchain like Monero and Zcash have been developed, concealing some transaction details to ensure participant safety. Although such privacy measures are not favored by authorities due to their exploitation of illicit activities, they serve a specific purpose.
The term “crypto” derives from the cryptographic principles and techniques employed for authentication purposes. These cryptographic methods are employed to govern the creation of new units known as minting tokens or reduce the supply of specific coins, a practice commonly known as burning tokens. Additionally, they ensure the integrity and security of networks, making them nearly impervious to hacking. When you engage in cryptocurrency transactions, the updates are automatically recorded on the respective cryptocurrency’s blockchain network through a series of authentication processes, such as Proof of Work (PoW) and Proof of Stake (PoS). Further elaboration on these processes will be provided later.
One of the primary advantages cryptocurrencies offer over traditional fiat currencies is financial freedom, where users possess complete control and access to their digital assets. In contrast, with traditional fiat currency, accounts can be frozen or seized under court orders or by federal agencies. While I do not endorse any illegal activities, it is worth noting that in some cases, corrupt government officials exploit this power to unjustly target individuals they perceive as troublesome, such as activists, journalists, or opposition leaders. Cryptocurrencies also present a highly efficient method for conducting cross-border transactions, offering speed and cost-effectiveness. Traditional currency transactions involve multiple processes and intermediaries, each taking a percentage cut, resulting in higher expenses. Additionally, currency conversion adds further costs and increases processing time.
In conclusion, cryptocurrencies are digital currencies that leverage cryptographic techniques to enable secure and decentralized transactions. Existing solely in electronic form, they operate on decentralized networks and are fortified through cryptography. By harnessing the capabilities of blockchain technology, cryptocurrencies provide enhanced financial autonomy, expedited cross-border transactions, and a range of other functionalities tailored to their unique designs and purposes.
In part two of this series, I will discuss the history of cryptocurrencies. It is important to go back to where it all began to understand the need for this technology. I will also discuss the industry’s evolution over time to understand the future it promises.
