The conceptualization of money has experienced profound evolution over the course
of history, transitioning from physical commodities such as cowrie shells and salt to
intangible digital representations, most notably cryptocurrencies. Emerging in
response to the global financial crisis of 2007, cryptocurrency represents a
decentralized, cryptographically secured form of virtual currency underpinned by
blockchain technology. It functions as a form of private money, operating
independently of traditional financial authorities such as central banks and
governments. This study undertakes a systematic literature review (SLR) to explore
the multifaceted challenges and debates surrounding cryptocurrencies, with a focus on
four principal themes: regulatory frameworks, Sharīʿah compliance, the ontological
nature of cryptocurrencies, and associated social implications. The findings reveal that
the absence of regulatory oversight in many jurisdictions contributes to high volatility
and opens avenues for misuse, including illicit transactions and tax evasion. These
regulatory gaps, coupled with uncertainties in intrinsic value and market behaviour,
have led to divergent Sharīʿah opinions regarding the permissibility of
cryptocurrencies. Notably, Sharīʿah scholars with a technical understanding of
blockchain are more inclined to issue favorable rulings compared to those with solely
traditional jurisprudential training. Several scholars have linked the volatility, potential
use in illicit transactions, lack of legal recognition, and decentralized nature of
cryptocurrencies to the prohibitive elements of riba (usury), gharar (excessive
uncertainty), and maysir (gambling) in Sharīʿah. Conversely, other researchers
contend that these characteristics are not intrinsic to cryptocurrencies themselves but
rather arise from external contextual factors—conditions that, if similarly applied to
fiat currencies, would also render them non-compliant with Sharīʿah principles. This
underscores the importance of technological literacy in contemporary Islamic legal
deliberation. In addition to theological and legal concerns, social dimensions such as
limited public awareness, cybersecurity risks, usability challenges, and environmental
degradation linked to energy-intensive mining processes are also critically examined.
Despite these concerns, the review identifies promising use cases in Islamic social
finance—particularly in zakāt distribution, waqf management, financial inclusion, and
Sustainable Development Goals (SDG) initiatives. Greater engagement between
Sharīʿah scholars and technology experts is essential for articulating a coherent
Islamic position on cryptocurrencies and harnessing their potential within Sharīʿah-
compliant financial ecosystems.
