Blockchain in Islamic finance refers to using shared, tamper-resistant ledgers to record asset ownership, execute Sharia-compliant contracts and trace financial flows, while avoiding interest, excessive uncertainty and pure speculation in the products built on them.
What a distributed ledger offers an Islamic bank
Islamic contracts rely on a sequence of dated acts: purchase, taking possession, resale. A shared ledger timestamps each step in a tamper-resistant way, allowing the Sharia board and the auditor to check that the required order was actually followed.
A smart contract to sequence purchase and resale
In a coded Murabaha, the software releases the resale offer to the customer only once the bank's title has been recorded. If the purchase is not registered, the sale cannot go out, which removes the risk of selling an asset the bank does not own.
When code is not enough to validate a contract
A programme does what it is told and does not judge legitimacy. Scholars point out that offer, acceptance and consent remain human acts, and that a badly configured smart contract can automate a prohibited late-payment charge as efficiently as a compliant clause.
Oracles and external data: the weak link
A smart contract depends on outside data, such as a market price or a delivery confirmation. If that source is wrong or manipulated, so is the execution; Sharia governance therefore has to cover how these oracles are chosen and monitored.
Tokenising real assets to issue sukuk
Tokenisation records shares in a tangible asset, a building, a fleet or an Ijara portfolio, on a digital ledger. It can split sukuk into small denominations and speed up settlement, but the legal structure, true sale and compliance remain those of a conventional sukuk issue.
A token is only compliant if the underlying asset is
A token backed by leased property inherits the rules of Ijara; a token representing only a receivable follows the rules on debt and can trade only at par. The digital wrapper does not change the Sharia classification of what it represents.
Instant settlement and the hand-to-hand rule
For exchanges of currencies or gold, Sharia requires simultaneous delivery of both sides. Atomic settlement on a blockchain, where both transfers execute together or not at all, is often presented as a way to meet this qabd requirement.
Gold-backed tokens: checking that the metal exists
Several projects issue tokens representing physical gold held in a vault. Before buying, ask whether the gold is allocated and identifiable, regularly audited, and whether the holder can take delivery; otherwise the token is merely a promise.
Cryptocurrencies: why scholars remain divided
In 2018 Egypt's Dar al-Ifta ruled bitcoin trading impermissible, citing uncertainty and the lack of an issuing authority. Other researchers treat it as property with use value. There is no consensus, and opinions often concern one specific asset.
Staking, DeFi lending and stablecoins: risk areas
Lending tokens for a fixed return on a decentralised platform replicates an interest-bearing loan. A stablecoin whose reserves sit in interest-bearing securities also raises questions. For staking, the analysis depends on the exact reward mechanism and varies between boards.
Speculation, leverage and crypto derivatives
Perpetual contracts, options and margin buying on crypto platforms generally combine financing interest, selling what one does not own and betting on price. They bring together riba, gharar and maysir and are rejected by the great majority of opinions.
Zakat, waqf and donations: traceability as an argument
For charitable funds, a blockchain lets donors follow their payment to the beneficiary and see how much went on costs. Some zakat and waqf institutions are testing these tools, with beneficiary privacy remaining a constraint to respect.
