The fundamentals of Cryptocurrency

Hello and welcome to this series on the fundamentals of cryptocurrency! Since diving into the world of cryptocurrency in 2015, I've mined, staked coins, launched projects, traded, bridged, minted, swapped, pooled, and burned crypto "assets". I got into crypto because I was interested in the blockchain as a new technology for finance (which is where my career has been primarily focused), and have tried to do as much as I can to understand the benefits and dangers of the space.

Through this series, I aim to demystify the complex world of crypto for beginners. Whether you're looking to understand the blockchain technology that made crypto possible, curious about how to securely buy and store cryptocurrencies, learn about the difference between hot and cold wallets, explore NFTs (non-fungible tokens) or what it means to "mine" a crypto, I've got you covered. The world of "DeFi" brought a whole new set of challenges and opportunities that we will discuss throughout this series, as well as recent events like the "Bitcoin halving".

I want to be sure to explain that this is not investment advice. I am not encouraging you to buy or use cryptocurrencies, tokens, NFTs or any other crypto related product. I won't shill some meme coin or promote exchanges. I'm writing this because I truly enjoy the crypto universe, and I believe it has potential to change much of the way information is used, stored, shared, and validated.

We'll start with the basics—what cryptocurrencies are and how they work—progressing to more advanced topics such as the Bitcoin halving, decentralized exchanges (DEXs) and centralized exchanges (CEXs), storing, coins vs. tokens and NFTs, laws and regulation, and knowing where to find reliable information on crypto.

My goal is to empower you with the knowledge to navigate the crypto space with a sense of understanding and hopefully help avoid common pitfalls, drawing on my firsthand experiences and the lessons I've learned over the past decade in the space.

I've drafted an outline that we may or may not stick to throughout the series. I'm interested to hear what you are curious about so please comment or DM me with questions or topics and we can cover those first.

What is Cryptocurrency?

Cryptocurrency is a form of digital currency that operates independently of central banks and trusted third parties. It utilizes cryptography to secure and verify transactions, which are recorded on a publicly accessible distributed ledger known as a blockchain. Since the launch of Bitcoin in 2009 by an individual or group under the pseudonym Satoshi Nakamoto, thousands of cryptocurrencies have emerged.

In the 2008 white paper, "A Peer-to-Peer Electronic Cash System," Nakamoto introduced blockchain, the foundational technology behind cryptocurrencies, enabling them to function similarly to traditional fiat currencies but without the oversight of central authorities. Blockchain technology addresses the critical "double-spending problem" of digital currencies by preventing the duplication of digital money, ensuring that each unit can only be spent once.

Traditionally, the global financial system has played a crucial role in validating monetary transactions. In contrast, the integrity of cryptocurrencies is upheld autonomously, with transactions recorded on public ledgers. Once transactions are confirmed by the blockchain, they become immutable, preventing any possibility of tampering or fraudulent activities, thus securing trust among users.

How Blockchain Enables Cryptocurrencies

At the heart of every cryptocurrency is blockchain technology. A blockchain is essentially a distributed ledger that is open to anyone. Once information has been recorded on a blockchain, it becomes very difficult to change. This technology ensures the integrity and transparency of the transaction data.

Every transaction made with a cryptocurrency is verified by a network of computers (nodes) and then added to the blockchain as a new block. This process ensures that the same digital tokens are not spent twice and that all transactions are securely recorded.

A distributed ledger in the context of blockchain technology functions similarly to traditional ledgers used in business accounting, where transactions are recorded chronologically. However, unlike traditional ledgers that require a central authority or intermediary to manage and validate transactions, a distributed ledger allows transactions to be recorded, shared, and synchronized across a network of multiple nodes or participants directly, without the need for a middleman. This decentralization is the core and fundamental benefit of blockchain technology, enhancing the transparency and security of data. The implications of this approach are vast, ranging from improved data management and integrity to revolutionizing supply chain operations by providing real-time, tamper-proof records. We will explore these applications in more depth in future articles, examining how they can transform industries by making data not only more accessible but also more reliable.

Proof of Work vs. Proof of Stake

Cryptocurrencies use various mechanisms to process transactions and secure their networks, the most common being Proof of Work (PoW) and Proof of Stake (PoS).

• Proof of Work (PoW): This is a consensus mechanism that involves solving complex mathematical puzzles to validate transactions and create new blocks. Bitcoin, the first cryptocurrency, uses PoW. It requires a significant amount of electrical and computational power.
• Proof of Stake (PoS): PoS is an alternative to PoW that is generally considered more energy-efficient. Instead of using computational work, PoS involves validating block transactions based on the number of coins a validator stakes or holds as a guarantee. Ethereum, another leading cryptocurrency, has transitioned to PoS.

We will explore these mechanisms in greater detail in future articles, highlighting their implications for security and energy consumption.

Understanding Cryptocurrency Supply

The supply of a cryptocurrency can be defined in various ways:

• Total Supply: The total amount of coins in existence right now (minus any coins that have been verifiably burned).
• Circulating Supply: The number of coins that are circulating in the public market and in the hands of the general public.
• Max Supply: The maximum number of coins that will ever exist in the lifetime of the cryptocurrency.

Not all cryptocurrencies have a max supply cap; for example, Bitcoin has a maximum supply of 21 million coins, which adds a scarcity aspect similar to precious metals like gold, potentially increasing its value over time due to limited supply.

Crypto Storage: Centralized vs. Self Custody

When it comes to storing cryptocurrencies, you have two main options: centralized and self-custody. Centralized storage involves keeping your crypto on an exchange wallet, where the exchange controls the private keys and essentially manages security for you. This can be convenient for traders who need quick access to their assets. However, it also poses risks if the exchange is hacked. On the other hand, self-custody means using cold wallets—offline storage such as hardware wallets or paper wallets. These provide the highest level of security since you control the private keys and your assets are not stored on an internet-connected server. Choosing the right storage option depends on your need for security versus convenience, and understanding these options is crucial for any crypto user.

Conclusion

In this introduction to cryptocurrency, we've covered the basic principles of what cryptocurrencies are, how blockchain technology supports their function, the significance of consensus mechanisms like PoW and PoS, and the critical topic of crypto storage. As we have seen, blockchain's decentralized nature offers significant advantages in terms of transparency, security, and efficiency over traditional systems, which has implications across data management and various sectors like supply chain management. We'll delve deeper into these topics in our upcoming articles. I realize this is probably a lot of information for a beginner so I'll leave it at that for now. If you enjoyed this discussion or have questions, feel free to like, comment, or message me directly. I'm also open to suggestions for future topics that you would like to see covered in this series.
