A Beginner’s Guide to NFTs on Bitcoin
You’ve probably heard of NFTs (Non-Fungible Tokens) on blockchains like Ethereum or Solana. But did you know that Bitcoin now has its own version of NFTs? They’re called Bitcoin Ordinals, and they’ve sparked a lot of buzz in the crypto world.
In this beginner’s guide, we’ll explore what Bitcoin Ordinals are, how they work, and why they matter — especially if you’re curious about NFTs or the evolution of the Bitcoin network.
What Are Bitcoin Ordinals?
Bitcoin Ordinals are a way to create and store digital assets — like images, text, videos, or code — directly on the Bitcoin blockchain.
Think of them as Bitcoin-native NFTs. They’re not hosted off-chain or on a sidechain — instead, they’re inscribed directly onto individual satoshis, the smallest units of Bitcoin.
Key Point:
- A satoshi (or sat) is 1/100,000,000 of a Bitcoin — the smallest divisible unit.
How Do Bitcoin Ordinals Work?
Bitcoin Ordinals are based on a concept called ordinal theory, which assigns a unique number to each satoshi as it is mined. Developers realized that they could “inscribe” data (like an image or text) onto a specific satoshi using Bitcoin’s Taproot upgrade (activated in 2021).
Key Technologies:
- Ordinal Theory: Tracks and numbers individual satoshis in the order they’re mined.
- Taproot Upgrade: Enables storing more complex data in Bitcoin transactions.
This process allows someone to embed data into a transaction, making that satoshi carry digital content forever on the blockchain.
What Can Be Inscribed?
With Bitcoin Ordinals, users have inscribed:
- Images and pixel art
- Videos and music files
- Text files and documents
- Games, code, or even memes
These inscriptions turn Bitcoin satoshis into unique digital collectibles, just like NFTs on other platforms.
How Are Bitcoin Ordinals Different from Traditional NFTs?
Feature Bitcoin Ordinals Ethereum NFTs
Blockchain Bitcoin Ethereum / Solana
Storage On-chain (fully) Mostly off-chain (e.g. IPFS)
Token Standard No token standard (uses satoshis) ERC-721 or ERC-1155
Smart Contracts Not used Used heavily
Flexibility Limited by Bitcoin’s design Highly customizable
Decentralization Very high High, but depends on platform
Bitcoin Ordinals are often praised for being simple, permanent, and decentralized, but they lack the programmability of Ethereum-based NFTs.
Why Are People Excited About Ordinals?
- First-ever NFTs on Bitcoin: It opens a new frontier for digital collectibles on the most secure blockchain.
- Permanence: Inscriptions live directly on Bitcoin’s blockchain and can’t be removed.
- Scarcity: Each inscribed satoshi is unique and verifiably rare.
- Cultural Value: The first few inscriptions (called early “Ordinal mints”) are already seen as historic digital artifacts.
How Can You Create or View Ordinals?
To Create (Inscribe) an Ordinal:
- Use platforms like Gamma.io or OrdinalsBot
- Upload your content (image, text, etc.)
- Pay a Bitcoin fee to have it inscribed on-chain
To View or Buy Ordinals:
Use Ordinals explorers like:

Are There Any Controversies?
Yes. Some in the Bitcoin community argue that Ordinals clutter the blockchain and raise transaction fees. Others believe it’s a revolutionary step for Bitcoin, enabling creative expression and innovation.
It’s a debate between Bitcoin as “digital gold” vs. Bitcoin as a versatile platform.
Key Takeaways
- Bitcoin Ordinals are digital assets inscribed directly onto Bitcoin’s smallest units, called satoshis.
- They allow the creation of NFTs on-chain without smart contracts or new token standards.
- Ordinals are made possible by the Taproot upgrade and ordinal theory.
- You can create, collect, and view Ordinals using special wallets and platforms.
- They represent a major milestone in Bitcoin’s history — blending collectibles, culture, and code.
