What is Ordinals Token?

Bitcoin Ordinals have exploded in popularity, with over 50 million Bitcoin NFTs inscribed since their launch. But what exactly are ordinals, and why are so many crypto users rushing to create or buy them? In this guide, you'll discover everything you need to know about ordinals and Bitcoin NFTs, including what makes them unique, how to buy, mint, and secure them, and how you can leverage OKX for maximum safety and accessibility. We’ll explore the technical details in plain English—plus practical, step-by-step instructions whether you’re a collector, creator, or just NFT-curious. By the end, you’ll know how to get started with ordinals, avoid common risks, and take your first steps with OKX’s industry-leading Bitcoin NFT tools.

What Are Ordinals? (Bitcoin NFTs Explained)

Ordinals—sometimes called "Bitcoin NFTs"—are digital assets created directly on the Bitcoin blockchain through a process called "inscription." Unlike typical NFTs on blockchains like Ethereum, ordinal NFTs represent individual satoshis (the smallest unit of Bitcoin, or "sats") that have been permanently inscribed with extra data, such as images, text, or code. This unique system allows ownership and tracking of each inscribed sat as a true NFT on the Bitcoin network.

So, what is an ordinal inscription? Simply put, it’s attaching metadata or digital files directly to a specific satoshi. Every Bitcoin transaction moves around 100 million sats per BTC, but only ordinal-inscribed sats store NFT-like data.

Bitcoin NFTs differ from those on Ethereum or Solana because they live natively within the Bitcoin blockchain—there are no smart contracts, no separate token standards like ERC-721, and all data is stored entirely on-chain. This brings greater permanence but also unique limitations (such as limited file size and no programmable royalties).

OKX was among the earliest major platforms to support ordinal NFTs, enabling users to interact with, buy, sell, or mint these assets in a secure and user-friendly way.

How Are Ordinals Different from Ethereum NFTs?

  • Native vs. Smart Contracts: Ordinals exist natively on Bitcoin, attached as data directly to individual sats. Ethereum NFTs, in contrast, require smart contracts and separate token standards on top of the base chain.
  • Permanence: Once inscribed, Bitcoin ordinal NFTs are immutable and persist as long as Bitcoin exists. Ethereum NFTs rely on external metadata storage, which could change or disappear.
  • Limitations: Bitcoin NFTs have restricted file sizes (due to block constraints), and collecting/trading them requires careful handling to avoid accidental loss. Ethereum NFTs support programmable logic and more flexible trading.

💡 Pro Tip: Ordinals stick to the actual Bitcoin blockchain, making their digital art and collectibles potentially more durable but needing extra attention during transfer and storage.

How Do Bitcoin Ordinals Work? (The Protocol Explained)

Ordinals operate thanks to a new way of tracking individual satoshis through the Bitcoin blockchain—a concept called "ordinal theory." In this system, every sat can be given a unique serial number. When you inscribe a sat, you attach digital data directly to it: this is the basis of a Bitcoin ordinal NFT.

What is an 'inscription'?

An inscription is a special kind of transaction where data is embedded into the Bitcoin blockchain, linked to a specific sat. That sat becomes unique, holding your NFT data forever. Anyone holding the private key controlling that sat owns the ordinal NFT.

How are ordinal NFTs tied to sats?

Ordinal NFTs are not separate tokens but encoded data bound to sats. Each inscribed sat can be tracked as it moves between wallets, and its data stays visible and immutable.

Protocol Steps (Plain English)

  1. Create or choose a piece of content (image, text, etc.), within the file size limits set by Bitcoin blocks.
  2. Use an inscription tool to build a Bitcoin transaction that attaches your content to a specific sat.
  3. Once confirmed, that sat turns into an ordinal NFT, trackable via compatible wallets or browsers.
  4. The NFT lives within that sat, forever part of the Bitcoin blockchain.

OKX’s wallet and marketplace are designed to identify and preserve inscribed sats accurately, helping avoid accidental NFT loss.

History: SegWit, Taproot, and the Birth of Ordinals

The ability to inscribe sats owes a lot to Bitcoin’s technical upgrades:

  • SegWit (2017): Enabled new data storage methods in transactions, opening up space for larger and complex data.
  • Taproot (2021): Improved privacy and flexibility, making it possible to store even more data efficiently.
  • Ordinals Protocol Launch (2022): Leveraged these upgrades, giving rise to the inscription of NFTs on Bitcoin. Since then, millions of Ordinals have been created.

The Life Cycle of an Ordinal NFT

  1. Inscription (Minting): An ordinal NFT is created when you inscribe data onto a sat.
  2. Wallet Storage: You must use an Ordinals-compatible wallet to view and move the inscribed sat without losing it.
  3. Trading/Transfer: Ordinals can be bought, sold, or transferred on supported marketplaces like OKX.
  4. Risks: Spending an inscribed sat as normal Bitcoin can destroy your NFT irreversibly.

💡 Pro Tip: Always double-check you’re sending ONLY the inscribed sat when transferring ordinal NFTs.

How to Mint (Inscribe) Your Own Bitcoin Ordinal

Minting your first Bitcoin ordinal is simple but requires careful attention to avoid costly mistakes.

What You Need:

  • An Ordinals-compatible wallet (e.g., OKX Wallet, Xverse, UniSat)
  • Enough Bitcoin to cover inscription and network fees
  • Optionally, testnet BTC for first-time experimenting

Potential Risks:

  • Using an incompatible wallet or address may destroy your NFT during transfer
  • Mistakenly spending inscribed sats can result in permanent loss with no recovery!

Easy Steps to Inscribe Ordinals

  1. Prepare Your File: Keep size under 400kb for faster confirmation and lower fees.
  2. Select a Wallet: OKX Wallet directly supports inscriptions—no need for external tools.
  3. Choose Inscription Tool or Platform: Use OKX’s in-app feature, or supported external tools if you prefer.
  4. Fund Your Wallet: Deposit a small amount of BTC for inscription/network costs (typically $5–$50, depending on congestion).
  5. Follow On-Screen Prompts: Upload your file, confirm the transaction, and review the inscribed sat once complete!

Using OKX’s inscription feature minimizes mistakes with built-in guides and previews. Mint confidently for yourself or your collection.

Security: Safely Storing, Trading, and Moving Ordinals

Because ordinals are bound to individual sats, handling them comes with unique challenges. Losing control over the specific sat means losing your NFT forever—unlike with traditional NFTs.

Here’s how to stay secure:

  • Always use a trusted, Ordinals-compatible wallet (like OKX Wallet) to avoid accidental spending.
  • Never merge, split, or transfer BTC in bulk unless absolutely sure which sats you are sending.
  • Regularly back up your wallet seed phrase in secure, offline locations.
  • Consider hardware wallets or air-gapped storage for valuable Ordinals.
  • Use platforms like OKX with dedicated Ordinals account separation and better asset display to reduce errors.

Common Mistakes When Handling Ordinals

  • Spending the wrong sat, leaving your NFT gone forever
  • Using wallets that “ignore” ordinals, causing hidden loss
  • Mixing inscribed sats with normal BTC without awareness
  • Not verifying the sat’s inscription order before sending

OKX Pro Tips for Ordinal Security

  • Backup your wallet seed phrase securely while never sharing it online
  • Use OKX’s “Ordinal-specific” transfer confirmation screens—these alert you if you’re about to transfer an inscribed sat
  • Review transaction previews to see which NFT(s) are moving
  • Leverage OKX’s cold storage integration for extra protection on high-value pieces

💡 Pro Tip: Always enable 2FA and regularly update your wallet app to the latest version for patches!

Risk Disclaimer: Always remember that Bitcoin NFT investments involve risk. Never share your private keys, and only use reputable wallets and exchanges like OKX for maximum safety.

Frequently Asked Questions

Are Bitcoin Ordinals the same as NFTs?

Bitcoin Ordinals share key features with NFTs—uniqueness, ownership, and verifiable provenance—but differ in how they’re made. Traditional NFTs use smart contracts and token standards (like Ethereum's ERC-721), while Ordinals are directly inscribed data on individual Bitcoin satoshis. For collectors, this means added permanence but some extra technical handling.

Is it safe to buy Ordinals?

When handled properly and with the right wallets, buying Ordinals is safe. The biggest risks involve sending inscribed sats incorrectly or using incompatible wallets. OKX tools and wallet integrations help reduce these risks with built-in protection, clear transfer previews, and secure backups.

What wallets support Ordinal NFTs?

Popular ordinal-compatible wallets include OKX Wallet, Xverse, UniSat, and Hiro. OKX Wallet is especially user-friendly, offering seamless inscription, transfer, and backup features designed to protect your NFTs.

How much does it cost to mint a Bitcoin Ordinal?

Minting an Ordinal involves two main fees: the Bitcoin transaction fee (which varies on congestion, usually $5–$50), and a small inscription fee (sometimes as low as a few cents on OKX). This is often cheaper than Ethereum’s peak minting fees.

Can I lose my ordinal NFT by accident?

Yes—if you spend or transfer the inscribed sat in error, your NFT is irreversibly gone. There’s no way to recover it. To safeguard NFTs, always use an Ordinals-specific wallet and carefully verify transactions before sending.

How do I trade Ordinals on OKX?

First, create your OKX Wallet and fund it with BTC. Then browse OKX’s Bitcoin NFT marketplace, where you can buy or list Ordinals. Sales and transfers include NFT previews and security prompts, helping ensure safe, error-free trading every time.
