When Money Becomes an Algorithm: Reading Cryptocurrency from a Sharia Finance Perspective
In an increasingly digital world, humans are gradually moving almost all economic activities into virtual spaces. Shopping no longer requires cash, and investment no longer necessitates physical exchange buildings. Even money is beginning to lose its physical form. This is the origin of cryptocurrency: not merely a technological instrument, but a symbol of a major shift in how humans perceive value, trust, and economic transactions.
When Satoshi Nakamoto introduced Bitcoin in 2008 through the concept of a peer-to-peer electronic cash system, many viewed it as a small experiment by the tech community. However, less than two decades later, cryptocurrency has evolved into a global phenomenon with a market capitalisation of trillions of dollars, giving rise to new ecosystems such as blockchain, Web3, and decentralised finance (DeFi).
Amidst this development, the Islamic world faces a complex question: is cryptocurrency halal? Or is it instead a new form of modern speculation that contradicts Sharia principles?
This question is far more complex than simply choosing between ‘permissible’ or ‘forbidden’. The debate is not just about digital assets, but how fiqh muamalah (Islamic jurisprudence of transactions) responds to rapid modern changes.
Between Innovation and Speculation
One of the greatest issues with cryptocurrency from a Sharia perspective is its extreme volatility. The prices of Bitcoin, Ethereum, and various digital tokens can rise and fall drastically within hours. In certain conditions, the crypto market resembles an arena for speculation rather than a space for productive investment.
It is at this point that concerns regarding the elements of gharar (uncertainty) and maysir (gambling) arise. Many modern crypto trading practices are conducted not out of an understanding of blockchain technology or digital asset fundamentals, but solely to chase quick profits. Phenomena such as ‘pump and dump’, meme coins, and leveraged gambling bring certain crypto activities closer to the speculative practices prohibited in Islam.
Recent academic studies in TASHDIQ suggest that the halal-haram dichotomy in crypto is too reductive, as there is a substantial difference between long-term investment based on technological fundamentals and speculative day trading. This means the primary issue may not lie in the technology itself, but in how humans utilise it.
Islam has never rejected economic innovation. Historically, Islamic civilisation is known to be highly adaptive to the development of trade instruments, business contracts, and cross-regional transaction systems. The principles of fiqh even affirm: ‘Al-ashlu fil mu’amalat al-ibahah’—in principle, transactions are permissible as long as there is no evidence prohibiting them.
Therefore, blockchain, as the underlying technology for cryptocurrency, is essentially neutral. It can be used for the public good, but it can also serve as a tool for destructive speculation.
Blockchain and the Future of Islamic Economy
Ironically, behind the controversy of cryptocurrency, blockchain technology possesses many characteristics that align with the spirit of Islamic economics. Blockchain offers transparency, immutable record-keeping, transaction efficiency, and more democratic data distribution. In certain contexts, this technology even has the potential to strengthen the principles of amanah (trust) and accountability within the Sharia economy.
Some research indicates that blockchain can be used for the management of zakat (alms), waqf (endowments), digital sukuk (Islamic bonds), and the real-time tracking of Islamic social fund distribution. Imagine if productive waqf funds could be monitored transparently by the public via blockchain, or if zakat distribution could be verified openly without data manipulation. In such contexts, blockchain could serve as an instrument to strengthen the economic governance of the Ummah.
Consequently, the greatest challenge for the Islamic world today is not merely issuing fatwas on crypto, but building an Islamic digital finance framework capable of separating productive innovation from destructive speculation.
