In the previous chapter, we learned what NFTs are: unique digital assets that live on a blockchain and represent ownership of something valuable. But to truly grasp how NFTs function—and later, to understand whether they are halal or haram—we need to look under the hood. What powers NFTs? How are they created, verified, and traded? And why does this matter for a Muslim seeking to engage ethically with technology?

At the heart of every NFT is the blockchain—a decentralised digital ledger that records transactions securely and transparently. Think of it as a giant, tamper-proof notebook that is not stored in one person’s office but copied and distributed across thousands of computers worldwide.

Each page in this notebook is called a block, and each block contains a record of recent transactions. Once a block is filled, it is linked (or “chained”) to the previous one, forming an unbreakable chain of records. This structure makes it almost impossible to alter past transactions without the entire network noticing.

When you buy an NFT, your ownership is written into this digital ledger for everyone to see. It’s public, verifiable, and permanent.

NFTs don’t just sit on the blockchain as static entries. They are powered by smart contracts, which are pieces of computer code that automatically execute rules.

A smart contract might say:

• “When someone pays 1 ETH, transfer this NFT to their wallet.”

• “Each time this NFT is resold, 10% goes to the original creator as a royalty.”

This automation removes the need for intermediaries. No bank, gallery, or auction house is required. Instead, the blockchain and the code itself guarantee that the rules will be followed.

For Muslim investors, this is significant: smart contracts can ensure fairness and transparency, but they can also embed problematic rules (for example, royalties tied to haram activities). Knowing how they work helps us evaluate their Shariah compliance.

Creating an NFT is called minting. Just like a government mint produces coins, digital minting produces NFTs. Here’s the process:

1. Creation of the Asset – An artist, musician, or developer creates a digital file (artwork, song, in-game item).

2. Writing Metadata – Information about the asset (title, description, creator’s name, properties) is recorded.

3. Deploying to the Blockchain – Through an NFT marketplace or custom smart contract, the asset is “minted” as a token on the blockchain.

4. Listing for Sale – The NFT can then be sold, traded, or gifted on various platforms.

Minting turns a regular digital file (which anyone can copy) into a unique, verifiable item with provable ownership.

To interact with NFTs, you need two things:

• Digital Wallets – These are apps (like MetaMask or Trust Wallet) that hold your NFTs and cryptocurrencies. They are like digital safes. Each wallet has a unique address, similar to a bank account number.

• Marketplaces – Platforms like OpenSea, Rarible, or Binance NFT, where users can buy, sell, and auction NFTs.

From an Islamic perspective, the choice of marketplace matters. If a platform is full of haram NFTs (like pornography or gambling-based tokens), trading there could mean exposure to impermissible activity, even if your purchase is halal.

One of the most misunderstood aspects of NFTs is ownership. Buying an NFT usually means you own the token—the blockchain entry proving you bought it. But it doesn’t always mean you own the copyright to the underlying image, song, or video.

For example:

• If you buy an NFT artwork, you may have the right to display it or resell the token.

• But you may not have the right to print copies, sell merchandise, or use it commercially unless the smart contract or license says so.

This distinction is critical in Islamic finance because gharar (uncertainty) arises when rights are unclear. If someone buys an NFT believing they own full rights but only owns a display token, this could be considered deceptive and impermissible.

To many, NFTs seem strange—why pay for something you can right-click and copy? But NFTs aren’t about the file itself; they’re about ownership, status, and utility.

Here are some reasons people value NFTs:

• Scarcity – Limited editions create rarity. Just as original paintings are more valuable than prints, original digital tokens hold a unique status.

• Community – Some NFTs act like membership cards, giving holders access to private groups, events, or clubs.

• Investment – Many people hope the value of their NFT will rise so they can sell at a profit.

• Utility – Certain NFTs unlock special features in games, apps, or platforms.

• Support for Creators – Fans buy NFTs to directly support artists or causes they care about.

The value of NFTs is not just in the file but in the social and economic ecosystem built around them.

While NFTs open opportunities, they are also risky. From an Islamic lens, these risks overlap with concerns about gharar and maysir.

• Speculation – Many buyers are driven by hype, flipping NFTs like lottery tickets, which resembles gambling.

• Fraud & Scams – Fake NFTs, phishing attacks, and rug-pull projects are widespread.

• Unclear Value – Unlike physical property, NFT prices are often arbitrary and volatile.

• Haram Content – Many NFTs depict impermissible images or themes.

Without careful screening, Muslims risk falling into transactions that are impermissible or at least doubtful (shubuhat).

One of the most fascinating aspects of NFTs is radical transparency. Every NFT transaction is recorded publicly on the blockchain. Anyone can see who bought what, when, and for how much.

This is empowering: no hidden interest rates, no hidden fees. But it’s also concerning: once recorded, a transaction cannot be undone. If someone unknowingly buys a haram NFT, that record exists forever.

This permanence raises questions of repentance and rectification in Islamic law. If a Muslim realises they engaged in haram NFT activity, they may stop, but the record remains as a digital footprint. Scholars may need to provide new ijtihad on how Muslims handle such irreversible records ethically.

While the media focuses on million-dollar JPEGs, NFTs have broader applications that may be more relevant for halal uses:

• Real Estate – NFTs can represent property deeds, streamlining transactions.

• Education – Diplomas and certificates as NFTs, preventing forgery.

• Identity – Digital ID systems using NFTs for secure, tamper-proof verification.

• Charity – Donors could receive NFT receipts tied to waqf or sadaqah projects.

These emerging uses show that NFTs are not inherently frivolous—they can serve as tools for transparency, accountability, and social good.

We’ve now peeled back the layers of NFTs. We know they are:

• Built on blockchains for transparency

• Powered by smart contracts for automation

• Minted as unique digital assets

• Traded on global marketplaces

• Valued for scarcity, utility, and community

But knowing how NFTs work is just the first step. The next—and far more important—step is asking: Are NFTs halal?

That depends on the rules of Islamic finance. The concepts of riba (interest), gharar (uncertainty), and maysir (gambling) are critical in evaluating whether NFTs are permissible or prohibited.

You now understand how NFTs are created, traded, and valued. But the bigger question remains: do they align with Islamic financial ethics? In the next chapter, we’ll explore the Shariah principles that guide Muslims in trade—riba, gharar, and maysir—and apply them directly to NFTs.
