1. The Anatomy of Money and the Genesis of Cryptocurrencies

Money, as a fundamental aspect of economic systems, serves as a multifaceted instrument with distinct characteristics and pivotal functions.

1.1. Functions of Money

In economics, money fulfills three important functions. To understand the origins of cryptocurrencies, it is imperative to delve into the historical trajectory that has brought us to the present moment. Examining the concept of currency and its evolution over time is a fundamental step in this exploration.

1.1.1. Money is a Unit of Measure

Money has a crucial role as a measuring tool. Simply put, it helps us measure and compare the costs of goods and services in a uniform way. This makes it straightforward for both buyers and sellers to gauge the value of goods and services and thus calculate the economic value of transactions.

1.1.2. Money is a Medium of Exchange

The second important function of money is that of a medium of exchangeem>.

Most people agree that trade and economics started with bartering, maybe in a central marketplace. But for the economy to really grow, we needed something more than just swapping goods. That's where money comes in.

Money solves a tricky problem in bartering called the "double-coincidence of wants." It means both the buyer and seller in a barter system have to want exactly what the other person has to offer. Like, one person brings eggs to trade but wants cheese, and another person has cheese and wants eggs. Money makes things way simpler!

1.1.3. Money is a Store of Value

The last and most important role of money is to function as a store of value, and this plays two significant roles. Firstly, it helps manage timing differences in trade and economics. With money, a person has the flexibility to sell his cheese today and decide whether to spend the proceeds immediately or keep them for later use.

Secondly, money maintains its purchasing power quite effectively over time, enabling decentralized trade. Essentially, this empowers that person to take his money to another marketplace elsewhere and spend it there.

1.2. The Characteristics of Money

Moving beyond the basic purpose of money, economists often delve into its distinct characteristics, and typically, six key attributes are the focus of these discussions. These characteristics play a pivotal role in understanding the nuances of how money operates within an economic framework.

1.2.1. Durability

The first critical feature is durability. For money to serve its purpose effectively, it must maintain its physical integrity over time, contributing to a stable and reliable medium of exchange.

If something is perishable such as wheat or livestock, while it can certainly hold value and act as a unit of measure, it is considered a commodity, rather than money.

1.2.2. Portability

This aspect is also a rationale behind the preference for money in a more compact and easily transportable form. This aligns with the second characteristic of money, which is its portability. While some historical societies, like certain civilizations that employed giant seashells or enormous wooden disks as forms of currency, showcase unconventional choices, the impracticality of such approaches would undoubtedly limit our daily movements.

1.2.3. Divisibility

The third characteristic is divisibility. Money should be easily divisible into smaller units without compromising its overall value. This characteristic allows for transaction flexibility, accommodating both small-scale and large-scale exchanges. The divisibility of currency enhances its adaptability to a range of economic scenarios. A counterexample for the divisibility of money would be the use of precious stones for example which cannot be divided without compromising the overall value.

1.2.4. Uniformity

Next, we consider uniformity. For a currency to be considered money, it needs to be uniform so that it's entirely fungible from one unit to another.

A uniform currency fosters a common understanding of its worth, promoting efficiency in trade and commerce. Again, a good counterexample would be precious stones, where each piece is unique.

1.2.5. Limited supply

Limited supply is another crucial attribute for money. Money should have a controlled and finite supply, as this helps prevent inflationary pressures and sustains the stability of a currency over time. If unlimited, money would be worthless, and no one would accept it.

1.2.6. Acceptability

In the context of money, acceptability refers to the widespread recognition and willingness of individuals and businesses to accept a particular form of currency as a medium of exchange for goods and services. For money to function effectively, it must be widely accepted and trusted within a given economic system. The degree of acceptability contributes to the usability and success of a currency in facilitating transactions and serving as a reliable means of exchange.

1.3. Fiat Money

Fiat money operates as a social construct built on trust. Unlike earlier times when the value of money was directly tied to the physical substance being exchanged, as was the case with gold coins, contemporary money holds no intrinsic value. It is no longer backed by a tangible asset, as was the practice during the era of the gold standard. Instead, the value of fiat money relies on the confidence and trust of the society that uses it.

Nowadays, money is essentially created through the printing or minting processes which are overseen by the central bank or note-issuing banks within a jurisdiction. The central bank utilizes the money supply as a key instrument to regulate various economic elements, including interest rates, bank reserves, and overall economic growth. Significantly, governments prioritize the management of inflation, considering it the paramount factor. This is chiefly achieved through the adjustment of policy rates, which, in turn, influences the money supply.

1.4. Centralized Digital Money

The concept of electronically transferable money dates back to the introduction of the telegraph, enabling wire transfers between banks and across countries.

However, the true proliferation of digital means of payment started with the exponential growth of the internet. As online connectivity expanded, it paved the way for the widespread adoption and advancement of digital financial transactions.

Credit card companies like American Express, Mastercard, and Visa have established extensive networks with merchants, making them the predominant method for B2C transactions both on the Internet and in shops due to their widespread acceptance.

But one important limitation remained - the transfer of money between individuals wasn't possible as these cannot receive payment directly from or to a credit card.

This is where digital payment companies like PayPal come into play. They provide a means for small businesses and individuals to utilize conventional banking and credit cards for the transfer of cash. Nevertheless, the process still relies on either or both parties having a bank account and/or credit card established.

The commonality among all these methods described above is their dependence on permission and their centralization. All require both transaction parties to trust a third party, thereby retaining a trust-based nature and susceptibility to certain issues such as a single point of failure, control or censorship, and potential corruptibility.

1.5. The Emergence of Cryptocurrency: Bitcoin

It is for the reasons mentioned above that the release of Bitcoin in 2009 was so disruptive. It marked the beginning of a new era, introducing the revolutionary idea of a currency that is not controlled by any central authority, immune to government interference, and resistant to censorship. This decentralized nature is achieved through blockchain technology, the backbone of most cryptocurrencies.

Bitcoin was introduced by an entity or individual under the pseudonym Satoshi Nakamoto. Nakamoto's stated vision was to create a decentralized digital currency that operated on a peer-to-peer network, eliminating the need for intermediaries like banks.

The simplified process of a Bitcoin transaction is as follows:

  1. Initiating the Transaction
    User A decides to send Bitcoin to user B. User A initiates the transaction by creating a digital message that includes information about the amount of Bitcoin he wants to send and user B Bitcoin address (like an account number).
  2. Creating a Transaction
    User A uses his digital wallet (an app or online service) to create a transaction. In simple terms, he specifies how much Bitcoin he wants to send and inputs User B's Bitcoin address.
  3. Digital Signature
    User A uses his private key (a secret code known only to him) to create a digital signature for the transaction. This signature is a cryptographic proof that the transaction is legitimate and comes from User A.
  4. Broadcasting to the Network
    The transaction is broadcasted to the Bitcoin network. This means it's shared with a vast network of computers (nodes) that validate and record transactions.
  5. Verification by Miners
    Miners, special nodes in the network, compete to solve complex mathematical puzzles. The first one to solve it gets the chance to verify and add a new block of transactions to the Bitcoin blockchain.
  6. Inclusion in a Block
    Once verified, the transaction is grouped with other transactions into a block. Miners compete to solve a complex mathematical problem, and the first one to solve it gets the right to add the block to the Bitcoin blockchain (a public ledger). This process is called proof of work.
  7. Adding to the Blockchain
    Once verified, the new block, including User A's transaction, is added to the blockchain. The blockchain is like a public ledger that records all Bitcoin transactions in a secure and chronological order.
  8. ConfirmationSeveral subsequent blocks are added to the blockchain, confirming the transaction's permanence and security. The more confirmations, the more secure the transaction.
  9. User B's Wallet Update
    User B's wallet sees the incoming transaction and updates his Bitcoin balance. Now, User B has the Bitcoin that User A sent.

In essence, a Bitcoin transaction involves creating a digital message, securing it with a digital signature, having the network validate and include it in the blockchain through a process called mining, and finally, confirming the transaction's completion. The decentralized nature of the blockchain ensures transparency, security, and consensus in the entire process.

2. What is Blockchain and How Does it Work?

2.1. What is Blockchain?

Blockchain lies at the heart of cryptocurrencies lies blockchain technology. A block in a blockchain is like a secure, sealed container holding a set of transactions, and it's linked to the ones before and after it, creating a chain of information that's open for everyone to see.

The blockchain can be imagined as a giant digital ledger that records all transactions, and everyone involved in a network has a copy. When someone wants to make a transaction, it gets verified by a network of computers instead of a central authority. Once approved, the transaction is added to a chain of previous transactions, creating a secure, unchangeable record. This not only makes transactions more transparent but also reduces the risk of fraud and central control. It's like a shared, tamper-resistant digital history book for financial activities.

2.2. Characteristics of Blockchain

2.2.1. Decentralization

Instead of having a central authority, like a bank, controlling and verifying transactions, blockchain operates on a decentralized network of computers (nodes). This means no single entity has complete control.

2.2.2. Transparency

Every transaction is recorded in a public ledger, visible to all participants in the network. This transparency ensures that everyone has the same information about transactions.

2.2.3. Security

Transactions are secured through advanced cryptography. Once a block of transactions is added to the blockchain, it becomes extremely difficult to alter. This makes blockchain highly resistant to fraud.

2.2.4. Immutability

Once information is added to the blockchain, it's nearly impossible to change. This permanence and resistance to tampering ensure the integrity of the recorded data.

2.3. How Blockchain Works

2.3.1. Transaction Initiation

When someone initiates a transaction, it gets grouped with other transactions into a "block".

2.3.2. Consensus

The network of computers (nodes) reaches a consensus on the validity of the transactions in the block. This is often achieved through a process called mining, where powerful computers solve complex mathematical problems to validate transactions.

2.3.3. Adding to the Blockchain

Once a consensus is reached, the block is added to the existing chain in a linear, chronological order. Each block contains a reference to the previous block, creating a chain of blocks - hence the term "blockchain."

2.3.4. Decentralized Verification

Other nodes in the network validate the new block, ensuring agreement across the system. This decentralized verification adds a layer of trust to the process.

3. Key Characteristics of Cryptocurrencies

3.1. Decentralization

Cryptocurrencies operate on a decentralized network of computers, often referred to as nodes. This means there is no central authority governing or controlling the currency, providing users with greater autonomy over their financial transactions.

3.2. Cryptography

The term "cryptocurrency" derives from the use of cryptographic techniques to secure transactions and control the creation of new units. Public and private keys play a crucial role in ensuring the security and authenticity of transactions.

3.3. Limited Supply

Many cryptocurrencies, including Bitcoin, have a capped supply, creating scarcity similar to precious metals. For instance, Bitcoin's maximum supply is capped at 21 million coins, adding a deflationary aspect to its economic model.

3.4. Anonymity and Pseudonymity

While transactions are recorded on the blockchain, the identities of the parties involved are often pseudonymous. This provides a level of privacy, though it has raised concerns about potential misuse.

Bitcoin is the first and most well-known cryptocurrency. It is often referred to as digital gold and is recognized as a store of value. It was the pioneer, in introducing the concept of blockchain and decentralized currency. Limited supply (21 million) and its decentralized nature contribute to its popularity. Bitcoin has the largest market capitalization among all cryptocurrencies, often comprising a significant portion of the total cryptocurrency market.

Ethereum introduced the concept of smart contracts, self-executing contracts with the terms of the agreement directly written into code. Smart contracts allow for programmable and self-executing agreements, expanding the use cases beyond simple transactions. Ethereum consistently ranks as the second-largest cryptocurrency by market capitalization.

Ripple aims to facilitate international money transfers by providing a fast and cost-effective alternative to traditional banking systems. It has gained traction as a solution for cross-border payments. Ripple has been among the top cryptocurrencies by market capitalization.

Created as the "silver to Bitcoin's gold," Litecoin is a peer-to-peer cryptocurrency known for its faster block generation time. Litecoin is often seen as a more accessible alternative to Bitcoin for everyday transactions due to its faster confirmation times and lower transaction fees. Litecoin has maintained its presence among the top cryptocurrencies by market capitalization.
