What is Cryptocurrency?
Cryptocurrency, often referred to as crypto, is a form of digital or virtual currency that utilizes cryptographic techniques to secure transactions and control the creation of new units [7][8][9][10][11]. Unlike traditional currencies issued by governments, cryptocurrencies operate on a decentralized network, typically a blockchain, which serves as a public financial transaction database [8][11].
At the heart of cryptocurrency technology is the use of encryption to ensure the security and integrity of transactions. This advanced coding is crucial for the safe storage and transmission of cryptocurrency data between digital wallets and to public ledgers [10]. Each transaction is verified and recorded in a blockchain, an immutable ledger that ensures transparency and prevents fraud [8][11].
Cryptocurrencies are not only used as a medium of exchange for online transactions but also as a speculative investment. They are fungible, which means that their value remains consistent across the board when bought, sold, or traded [8][11]. This differentiates them from non-fungible tokens (NFTs), whose values are not fixed and depend on the digital asset they represent [8][11].
The first cryptocurrency, Bitcoin, was introduced in 2009 and remains the most well-known. It was originally developed as a payment method that could operate independently of central financial authorities [9][10]. Following Bitcoin's success, numerous other cryptocurrencies like Litecoin and Ethereum have emerged, each with unique functionalities and intended uses. For instance, Ethereum not only supports transactions but also facilitates smart contracts and decentralized applications (DApps) on its network [9].
To engage with cryptocurrencies, individuals must use cryptocurrency wallets. These wallets can be software-based—either stored on a computer or a mobile device, or cloud-based services. They are essential for managing the encryption keys that authenticate the user's identity and link them to their cryptocurrency holdings [7][10].
Despite their advantages, cryptocurrencies operate in a market that is currently free from government regulation, though they are recognized as taxable assets by authorities like the Internal Revenue Service [8][11]. This lack of regulation contributes to their volatility, making them a high-risk, potentially high-reward investment [8][11].
In summary, cryptocurrency represents a significant shift in the way individuals and institutions think about and use money. As digital currencies continue to evolve, they challenge traditional financial systems and offer a new paradigm for secure, decentralized transactions [7][8][9][10][11].
How Does Cryptocurrency Work?
Cryptocurrency transactions differ significantly from traditional fiat currency transactions. Rather than transferring funds between accounts, cryptocurrency dealings involve shifting data within a blockchain, which acts as a public ledger recording every transaction and ensuring that funds are associated with a specific blockchain address [19].
Blockchain Technology
The blockchain is fundamental to how cryptocurrencies operate. It is a distributed public ledger that records all transactions and is maintained by currency holders [21]. Each transaction is stored as a "block" and added to the existing chain, creating a secure and transparent chronological record of all activity [13][14]. This technology allows participants to confirm transactions without the need for a central clearing authority, which is a major shift from traditional financial systems [15].
Transactions on the blockchain start with the creation of data blocks, which are then broadcasted to the network for validation. This process involves multiple stages including creating, broadcasting, and confirming the transactions [19]. Once a transaction is initiated, it is sent to a memory pool where it is stored until a miner or validator picks it up to include in a new block [14]. This block is then verified and, once filled with transactions, is closed and encrypted [14]. The completed block is added to the blockchain, linking it to the previous block and forming a chain. This chain of blocks is immutable, meaning once data is entered, it cannot be altered, thus ensuring the security of the records [13][14].
Cryptographic Techniques
Cryptographic methods are crucial in securing and validating transactions on the blockchain. Cryptocurrencies use advanced cryptographic techniques to generate public and private keys, which are essential for transaction security [16]. Public keys act as addresses to which cryptocurrencies are sent, while private keys function as passwords that authorize the sending of cryptocurrencies from one address to another [16].
Transactions are digitally signed using these keys to ensure authenticity and prevent fraud [20]. The blockchain uses algorithms like SHA256 to encrypt data, ensuring that even if data is intercepted, it cannot be read without the corresponding decryption key [16]. This encryption process not only secures transactions but also verifies the transfer of funds, controlling the creation of new monetary units and maintaining the integrity of the blockchain [15][16].
In summary, the workings of cryptocurrency involve complex systems of blockchain technology and cryptographic techniques. These systems ensure that transactions are secure, transparent, and decentralized, challenging traditional financial frameworks and reshaping our understanding of money in the digital age [19][21].

Bitcoin, created in 2009 by an individual or group using the pseudonym Satoshi Nakamoto, is the pioneer of cryptocurrencies and operates on its own blockchain technology [24][28]. It is designed as a decentralized digital currency without the need for a central authority, making it resistant to government manipulation and control [22][25]. Bitcoin's blockchain serves as a public ledger, recording all transactions securely through a process known as mining, which involves solving complex mathematical problems [24][28]. Despite its position as the leading cryptocurrency, Bitcoin faces challenges such as scalability issues, which led to the creation of Bitcoin Cash in 2017 to allow faster transaction processing and lower fees [24].
Ethereum
Ethereum, launched in 2015, extends beyond a mere currency to a platform for decentralized applications (dApps) and smart contracts, which are executed automatically when conditions are met [23][25]. Unlike Bitcoin, Ethereum's blockchain is programmable, allowing developers to create a variety of applications that go beyond financial transactions [25]. Ether, the native cryptocurrency of Ethereum, is used to execute these smart contracts and run applications within the network [23][25]. Ethereum's flexibility and support for complex operations have established it as a key player in the digital currency space, particularly with the rise of ICOs and the NFT market [28].
Altcoins
Altcoins refer to cryptocurrencies other than Bitcoin and often include Ethereum. These digital currencies vary greatly in their purposes and underlying technologies [22][26][27]. Some altcoins like Litecoin and Bitcoin Cash were created to improve on Bitcoin's limitations, such as transaction speed and cost [24][28]. Others, like Dogecoin, started as a joke but gained popularity and are used similarly to other cryptocurrencies [28]. There are also specialized altcoins such as Storj, which focuses on decentralized storage solutions, or Namecoin, which provides decentralized DNS services [22]. Altcoins can be categorized into various types, including payment tokens, stablecoins, security tokens, utility tokens, and governance tokens, each serving different roles within the digital ecosystem [26][27].
The cryptocurrency landscape is rich and varied, offering numerous options beyond the well-known Bitcoin and Ethereum.
