Introduction

Over recent decades, the world's financial landscape has undergone transformative shifts, with technological advancements frequently spearheading these evolutions. A particularly notable milestone in this progression was January 2009, marking the advent of a novel digital currency, Bitcoin^[1] (BTC), introduced to the global community by the enigmatic Satoshi Nakamoto. Prior to Bitcoin's emergence, the idea of a decentralized digital currency remained largely theoretical, with various attempts faltering due to trust-related technical impediments. However, Bitcoin's pioneering architecture paved the way for an unprecedented mode of value transfer [1].

Within this framework, trust issues traditionally associated with anonymous digital transactions were addressed, not by a centralized institution, but via cryptographic proofs and a decentralized mechanism. This resulted in a system wherein value could be exchanged without the requisite of a third-party guarantor. Such an innovative approach has since paved the way for the creation and launch of approximately 23,000 diverse cryptocurrencies by 2023, each aspiring to address unique challenges or carve niche applications within the vast financial ecosystem.

Yet, while the promises of cryptocurrencies are manifold, they have also ushered in an array of complexities and challenges. As these digital assets gain increasing prominence, there's an escalating need to comprehend their potential ramifications for the entrenched financial systems, especially the traditional banking sector, which has long stood as the linchpin of global financial operations. The examination of this matter extends beyond mere academic curiosity; the impact of cryptocurrencies on the banking sector holds the potential to reshape economies, redefine financial sovereignty, and redraw the boundaries of monetary policy.

The objective of this article is to delve into the intricate interplay between cryptocurrencies and the conventional banking system. By doing so, we aim to discern potential synergies, points of contention, and the 'roadmap' for future coexistence and convergence of these two distinct financial entities. This exploration serves not only to clarify the existing landscape but also to illuminate pathways through which both systems might complement and challenge each other in the unfolding financial horizon.

Cryptocurrency and Its Origin

The traditional fiat-based payment system has been historically plagued by high transaction fees and protracted settlement periods. This inefficiency sparked an interest in alternative currencies, aimed at streamlining peer-to-peer (P2P) payments without the need for intermediaries. This thirst for enhanced speed and efficiency catalyzed the surge of digital currencies with notably reduced settlement durations.

Before the emergence of cryptocurrencies, several forms of digital currencies had been conceptualized. The most prevalent among these were currencies instituted by entities and operated on proprietary platforms. Examples include loyalty points initiated by companies or digital coins developed by online platforms. Essentially, these digital currencies were underpinned by a centralized model. Renowned e-commerce firms like Rakuten and iHerb have leveraged such centralized digital currencies, resembling real money but operating exclusively within their respective platforms. China's social media titan, Tencent, introduced the Q-coin, which could be bought with Yuan and expended within Tencent's sphere of services. Another instance is the in-game currency of World of Warcraft; it's a token that can be earned solely through in-game activities and isn't tradable for fiat money, as elaborated by Halaburda (2016) [2].

Transactions with these centralized digital currencies were confined within their specific platform and were tailored to buttress the business strategies of the issuing institutions. Their utility as substitutes for fiat money was constrained. Given their centralized nature, they couldn't be acknowledged as legitimate legal tenders. Consequently, decentralized digital currencies surfaced as a promising alternative to fiat money due to their inherent feature of dispensing with the need for a central authority for transaction verification.

However, the evolution of these decentralized currencies wasn't devoid of challenges. A paramount concern was the 'double-spend' conundrum, where the same digital coin could be expended multiple times. This quandary remained unresolved for a protracted duration, hindering the widespread adoption of decentralized coins. Ensuring an accurate reflection of every transaction in the digital ledger and precluding double-spending necessitated a robust ledger system devoid of central oversight. The synthesis of this requirement led to the inception of the blockchain technology, and thus, the birth of cryptocurrency, offering a groundbreaking solution to the longstanding issues that earlier digital currencies failed to address.

The pioneering cryptocurrency, eCash, operated as a centralized system under the ownership of DigiCash, Inc., which later transitioned to eCash Technologies. While eCash was phased out by the late 1990s, the cryptographic protocols it utilized effectively circumvented the double-spending issue. Its utilization of blind signatures ensured user confidentiality and set the stage for subsequent cryptographic developments. Shortly thereafter, 'digital gold' currencies gained traction, with e-Gold emerging as the most prominent. Recognized as the first successful online micropayment system, e-Gold ushered in numerous innovations that made transactions more accessible and secure. Nevertheless, its inability to address regulatory compliance culminated in its shutdown in 2008, despite an annual transaction volume exceeding 2 billion US dollars, as noted by Lam and Lee (2015) [3].

The 2008 global financial crisis, coupled with rising skepticism towards the conventional financial system, bolstered significant interest in cryptocurrency. It was within this turbulent backdrop that an individual or collective operating under the pseudonym Satoshi Nakamoto unveiled the seminal white paper titled "Bitcoin: A Peer-to-Peer Electronic Cash System" in 2008 [4]. Nakamoto's brilliance wasn't rooted in devising a brand-new technology per se but in amalgamating existing cryptographic techniques to forge a decentralized system where trust was established through network consensus rather than institutional intermediaries.

Bitcoin introduced the paradigm of a distributed ledger where transactions were not overseen by a singular entity but verified by nodes within a decentralized network. The employment of cryptographic hashes guaranteed data integrity, while the proof-of-work mechanism shielded the system from malevolent attacks and facilitated transaction history consensus. Additionally, Bitcoin's design incorporated a supply ceiling, addressing inflationary issues commonly associated with conventional fiat currencies.

Bitcoin's resounding success catalyzed the genesis of myriad other cryptocurrencies, each tweaking or refining the original blueprint to cater to diverse needs or ideologies. From addressing privacy concerns, as demonstrated by Monero and Zcash, to embedding smart contract functionalities, exemplified by Ethereum, the cryptocurrency landscape underwent rapid metamorphosis. Such expansive diversification of digital assets, anchored in Bitcoin's foundational principles, underscores the technology's adaptability and vast spectrum of potential applications.

In comprehending the genesis of cryptocurrency, it is imperative to recognize it not merely as an offshoot of technological evolution but also as an embodiment of aspirations towards decentralization, transparency, and financial self-determination. This recognition is essential to appreciate the profound shifts in financial paradigms ushered in by cryptocurrencies, positioning them not just as monetary tools but as harbingers of a more autonomous financial future.

Bitcoin

Cryptocurrency, denoted as Bitcoin or BTC, has emerged as a digital medium for the exchange of value, capable of being tendered for goods and services, procured from peers, or directly purchased via exchanges and vending machines. These bitcoins can be digitally transferred, employing a mix of proprietary software, application-based, or various online platforms, colloquially referred to as 'wallets'. Another acquisition avenue for Bitcoin is through a process known as 'mining'.

Bitcoin's operational infrastructure rests on a peer-to-peer (P2P) network. Transactions are facilitated directly between users, eschewing intermediaries. Rather than centralizing transaction validation, Bitcoin decentralizes this responsibility, spreading it across the network. Each transaction is etched onto a public ledger termed as the 'blockchain'. These transactions are authenticated by network nodes - essentially individuals leveraging computer systems fortified with Bitcoin-specific software. Upon initiating a transaction, it is broadcasted to users and subsequently ratified by the network. Post-verification, the transaction is enshrined in the blockchain, culminating in the transaction's completion. This intricate ledgering process is termed 'mining'. Individuals proffering computational power for this purpose are coined as 'miners'. Bitcoins are minted as an incentive for solving cryptographic puzzles utilizing transactional data. As a result, triumphant miners are rewarded with newly minted bitcoins in addition to transaction fees.

Each transaction embodies both input and output details. Inputs encapsulate references to the outputs of antecedent transactions. Conversely, transaction outputs encompass the recipient's address paired with the pertinent amount, as delineated by Nirupama and Lee (2015) [5]. Typically, a specified quantum of bitcoins is dispatched from a Bitcoin wallet to a designated address, contingent on the wallet retaining a sufficient Bitcoin balance derived from previous transactions. Notably, these transactions aren't encrypted, permitting transparent scrutiny within the blockchain vis-à-vis associated Bitcoin addresses. However, the identities of both the sender and recipient remain cloaked in anonymity. Bitcoin wallets traditionally possess a private key or seed value, instrumental in transaction signatures. This secure data fragment furnishes mathematical evidence asserting that the transacted coins emanate from the wallet's proprietor. Employing this private key coupled with its signature ensures exclusive account access to its rightful owner, rendering the transactions immutable to external alterations.

Mining in the Bitcoin realm extends beyond the mere generation of new bitcoins. It acts as the mechanism for appending vetted transaction records to Bitcoin's public ledger. These records are aggregated into units called blocks. Every block is stamped with a timestamp and points to its predecessor, leading to an intertwined chain of blocks, whence the term 'blockchain' originates. The sequential mining ensures that once ingrained, data within a block is retroactively immutable. An exhaustive record of transactions resides in the primary chain. Every block in this sequence is intrinsically linked to its precursor, traceable back to the very inaugural block, termed the 'genesis block'. Yet, certain blocks, not part of the main chain, emerge; these are labeled 'orphaned' or 'stale' blocks. Their genesis can be ascribed to simultaneous block production by multiple miners or malevolent attempts to reverse transactions. When parallel block validations occur, algorithms steer the system to uphold the primary chain by selecting the block bearing the highest value.

Bitcoin miners' compensation is grounded in various systems. Predominantly, Bitcoin harnesses the Hashcash Proof-of-Work (PoW) system, deploying the SHA-256 hashing algorithm. The PoW modus operandi predicates rewards on the volume of successfully mined blocks. As such, the mining landscape is fiercely competitive; the first miner to decipher the stipulated cryptographic puzzle or achieve the highest value accrues all the freshly minted bitcoins, leaving peers empty-handed. Consequently, these rewards serve as a catalyst, spurring miners into proactive data block extraction. It's noteworthy that mining mandates substantial computational heft and can be significantly energy-intensive.

Another prevalent mechanism is the proof-of-stake (PoS). Contrasting PoW, the PoS paradigm obviates extraneous work, basing rewards on the quantum of coins held by investors. For instance, an investor with a 1% currency stake stands a chance to mine 1% of the currency's PoS blocks, as expounded by Nirupama and Lee (2015) [5]. Overall, this structure minimizes computational demand, bolsters currency security, and is occasionally fused with other systems, epitomized by Peercoin, the pioneer cryptocurrency leveraging PoS.

Bitcoin's inherent design caps its quantity at 21 million. Thus, the bitcoins conferred to a miner for successfully appending a block undergoes a halving every 210,000 blocks, approximating four years, adhering to the Bitcoin protocol. At its 2009 inception, miners were remunerated with 50 new bitcoins for every block assimilated into the blockchain. However, by July 9, 2016, this reward witnessed a halving to 12.5 bitcoins. As of October 6, 2017, the Bitcoin network boasted a circulating supply of 16.606 million, juxtaposed against a total market capitalization of USD 73.1 billion^[2].

Bitcoin's Distinctive Features

Bitcoin exhibits a set of unique characteristics, as delineated in Figure 1 [6].

Figure 1. Bitcoin's Distinctive Features

Decentralization: While akin to conventional currencies that are traded digitally, Bitcoin serves as a medium for electronic purchases. What distinguishes it from fiat or other platform-based digital currencies is its decentralized nature. This implies the absence of a singular group or institution exerting control over the Bitcoin network. Instead, its supply is algorithmically governed, accessible to anyone with internet connectivity.

Flexibility: Setting up Bitcoin wallets or addresses is a straightforward online process, devoid of fees or regulatory constraints. Moreover, Bitcoin transactions aren't tethered to any specific locale, enabling seamless cross-border transfers.

Transparency: Every transaction is broadcast across the entire network. Mining nodes or miners validate these transactions, integrate them into a block they forge, and then disseminate this finalized block to other nodes. The blockchain, which is an open, distributed ledger, houses records of all transactions. Given its accessibility, every miner retains a copy, facilitating transaction verifications.

Speed: Transactions propagate in mere seconds, with miners necessitating roughly 10 minutes for transaction confirmation. This expedience ensures that Bitcoin transfers can be executed globally, typically culminating in minutes.

Low Transaction Fees: Historically, transactions could be executed without requisite fees. However, users can opt to add an extra charge to expedite the transaction process. Currently, low-priority mining transactions (characterized by age and input size metrics) predominantly serve as indicators for spam transactions, with the majority of miners anticipating a fee inclusion for each transaction. Initially, miners' incentives stemmed largely from newly minted coins. But as the number of bitcoins in circulation inches closer to its upper bound, transaction fees will eventually serve as the primary incentive for miners, compensating for the resource-intensive verification process.

In essence, Bitcoin's architecture, rooted in decentralized protocols and bolstered by attributes like transparency and low costs, has carved out its niche in the evolving financial landscape. Its inherent design, coupled with the aforementioned features, augments its adoption and utility in the global market.

Underlying Mechanics of Cryptocurrency

Cryptocurrency, a digital or virtual embodiment of currency, marks a significant leap in financial technologies, birthed from the ashes of prior unsuccessful endeavors to digitize currency. This foundational success can be attributed to an entity or individual operating under the pseudonym Satoshi Nakamoto, who introduced Bitcoin (BTC) to the world. Distinct from its antecedents, Bitcoin harnessed a blend of pre-existing technologies to actualize the concept of a decentralized digital currency.

At the core of Bitcoin's operation lies an amalgamation of key programming principles and functions. A pivotal process involved is "hashing", wherein data undergoes transformation into a standardized series of letters and numbers. This conversion plays an instrumental role in safeguarding transactional integrity, facilitating secure peer-to-peer node interactions within the network. Once hashed, this data, now termed a "hash," is lodged into a public ledger identified as a "block". Incorporated within these blocks are temporal stamps for each transaction, ensuring both transparency and traceability [7].

Cryptocurrency's dynamism is encapsulated in its continual evolution. Each novel cryptocurrency transaction engenders a fresh block. What sets these blocks apart is their interconnected nature, achieved via synchronized hash functions, leading to the inception of what is ubiquitously recognized as the "blockchain". This blockchain is an ordered chain of blocks, each referencing its predecessor, culminating in a digital ledger fortified against unauthorized breaches.

To guarantee the authenticity and reliability of transactions within this framework, the "proof-of-work" algorithm is employed. This consensus mechanism mandates network participants to undertake intricate computational challenges, wherein their solutions streamline the incorporation of new blocks into the blockchain. Courtesy of this meticulous verification process, transactional integrity is maintained, reinforcing the decentralized essence of the cryptocurrency system, and rendering it resilient against malevolent threats.

Cryptocurrency and the Traditional Banking System

Since their inception, cryptocurrencies have posed an intriguing challenge to the well-established edifice of traditional banking, which for centuries held dominion over global financial transactions. By their nature, cryptocurrencies aren't mere digital assets; they assume roles typically ascribed to sovereign currencies, acting as mediums of exchange, value stores, and standard units of financial accounting.

A defining feature of cryptocurrencies is their potential for transactional optimization. Given their inherent structure, cryptocurrencies enable swifter, cost-effective, and secure transactions without the mandate for conventional intermediaries. Such heightened efficiency stems directly from their decentralized nature, facilitated by the underlying blockchain technology that assures a transparent and immutable transactional record [8].

Recognizing the transformative potential of these digital currencies, various conventional banks have embarked on integrating blockchain into their operational frameworks. This merger aims not only to enhance existing services but also to introduce novel offerings tailored to meet the evolving demands of their clientele. A case in point is the initiative by the "Eurasian Bank" Corporation, championed by the leadership of Kazakhstan, which prides itself on its minimal fee structure for blockchain-based transactions. Similarly, Switzerland's SEBA Bank has pioneered an approach that merges traditional banking services with blockchain technology. Their model, emblematic of the future of banking, proffers a harmonized digital experience, grounded in strict regulatory compliance and buttressed by the analytical insights of financial experts.

However, this revolutionary shift towards digital finance isn't devoid of pitfalls. The very essence of cryptocurrencies—their decentralization and absence of centralized oversight—renders them susceptible to misuse. Their design, inherently bypassing conventional financial gatekeepers, can be a double-edged sword, paving avenues for illicit activities that could potentially jeopardize a nation's financial stability. Such vulnerabilities have spurred nations to proactively respond by crafting legal frameworks tailored to the unique challenges cryptocurrencies pose.

Notably, the Board of Governors of the Federal Reserve System in the United States has devised specific guidelines to govern banks' interactions with crypto-assets. In a similar vein, Hong Kong's recent licensing structure imposes stringent standards on crypto trading, while countries like Uzbekistan and Egypt have curated regulatory policies overseeing cryptocurrency operations. Conversely, countries like Afghanistan have adopted a more conservative stance, outlawing any activity related to cryptocurrency and implementing severe punitive measures for infringements.

The varied responses to cryptocurrencies highlight a global struggle to strike a balance between capitalizing on the potential benefits of these digital assets and mitigating the inherent risks. While some nations embrace the transformative promise of decentralized finance, others are driven by caution, aiming to safeguard traditional financial ecosystems against potential disruptions and threats. This dynamic interplay between the novel world of cryptocurrencies and the established realm of traditional banking underscores a complex yet fascinating phase in the evolution of global finance.

Incorporation of Cryptocurrency in Traditional Banking

The rapid ascent of cryptocurrency from a fringe financial experiment to a global financial instrument has spurred an inevitable intersection with traditional banking (fig.2). As these two financial paradigms converge, it's evident that traditional banking institutions are neither passive observers nor mere competitors. Instead, many have opted for collaboration, seeking ways to integrate the advantages of cryptocurrency into their established frameworks.

1. Blockchain-Based Settlement Systems: Recognizing the speed and efficiency of blockchain, several banks have begun to explore or implement distributed ledger technology (DLT) for settlements. This allows for instantaneous or near-instantaneous clearing of transactions, reducing the time and cost traditionally associated with interbank transfers, especially on an international scale.

2. Bank-Issued Digital Currencies (CBDCs): Central banks from various nations are researching or piloting their digital currencies, commonly referred to as Central Bank Digital Currencies (CBDCs). These digital currencies leverage blockchain technology to offer the benefits of cryptocurrencies, such as quicker transactions and reduced costs, while retaining the regulatory oversight and stability associated with traditional currencies.

3. Cryptocurrency Custodial Services: Recognizing the growing demand for cryptocurrency investment and the associated challenges of securely storing digital assets, some traditional banks have begun offering custodial services. These services provide customers with the security of storing their cryptocurrencies with a regulated institution, combining the cryptographic security of digital assets with the institutional trust of banking entities.

4. Cryptocurrency Trading Platforms: In response to the burgeoning cryptocurrency market, some banks have introduced or are in partnership with trading platforms, allowing their customers to purchase, sell, or trade cryptocurrencies. These platforms, while operating similarly to independent crypto exchanges, offer the added assurance of a traditional banking infrastructure, often with enhanced security measures and streamlined user interfaces.

5. Cross-Border Payments and Remittances: Leveraging the borderless nature of cryptocurrencies, some banks have integrated blockchain solutions for international remittances. By using cryptocurrency or blockchain as a bridge currency or medium, banks can drastically reduce the time and fees associated with cross-border transfers, offering competitive rates and faster services to their customers.

6. Collaborative Research and Innovation Hubs: Understanding the evolving landscape, many banks have established dedicated research teams or innovation hubs, collaborating with fintech startups, blockchain developers, and other stakeholders. These collaborative environments aim to foster innovations that seamlessly blend the strengths of both traditional banking and the cryptocurrency domain.

In the evolving narrative, it's evident that traditional banks are not content with mere coexistence; they aim for symbiosis. By incorporating the strengths of cryptocurrency—its technology, speed, and cost-effectiveness—into their operations, banks aspire to enhance their services, cater to a new generation of clients, and fortify their relevance in an increasingly digital financial future.

Regulatory Landscape and Challenges

The proliferation of cryptocurrency within the global financial arena has brought with it a myriad of regulatory complexities. As a relatively novel entity, cryptocurrency exists at the intersection of technology, finance, and law, and poses unique challenges for regulatory bodies worldwide. The evolving landscape is a tapestry of diverse approaches, each reflecting the individual socio-economic and political realities of different jurisdictions (Table 1).
