Bitcoin has long been perceived as a blockchain primarily focused on financial transactions and value preservation, often described as digital gold. However, this narrative is evolving with the emergence of Ordinals, a protocol that could redefine Bitcoin's capabilities by introducing native NFTs to its blockchain.
What Are Bitcoin Ordinals?
Ordinals are a protocol enabling the creation of native NFTs on the Bitcoin blockchain by attaching data (text, images, videos, etc.) to individual satoshis—the smallest unit of Bitcoin (1 satoshi = 0.00000001 BTC). Launched on January 20, 2023, by developer Casey Rodarmor, Ordinals differ from traditional Bitcoin NFTs by being fully on-chain, requiring no Layer 2 solutions or protocol modifications.
Key Innovations: Taproot and SegWit Upgrades
Ordinals became feasible due to Bitcoin’s Segregated Witness (SegWit, 2017) and Taproot (2021) upgrades, which expanded data storage capacity per block. These upgrades enabled:
- Larger data attachments (e.g., high-resolution images).
- Simplified arbitrary data storage via Taproot’s scripting flexibility.
How Do Bitcoin Ordinals Work?
The Ordinal Theory
This framework assigns a unique identity to each satoshi based on:
- Ordinal numbering: Satoshis are indexed chronologically by mining order.
Rarity tiers: Satoshis gain rarity based on historical events (e.g., post-halving blocks).
- Common: Standard satoshis.
- Uncommon: First satoshi of a block.
- Rare: First satoshi post-difficulty adjustment (~every 2 weeks).
- Epic: First satoshi post-halving (~every 4 years).
The Inscription Process
- Data attachment: Users link digital artifacts (e.g., artwork) to a specific satoshi via a Bitcoin transaction.
- Witness data: The artifact is embedded in the transaction’s witness field, ensuring on-chain permanence.
- Preservation: The inscribed satoshi becomes a non-fungible asset, tradable like traditional NFTs.
Ordinals vs. Traditional NFTs
| Feature | Traditional NFTs (e.g., Ethereum) | Bitcoin Ordinals |
|-----------------------|-----------------------------------------------|--------------------------------------|
| Data Storage | Metadata often off-chain (e.g., IPFS) | Fully on-chain |
| Rarity Basis | Traits/scarcity (e.g., CryptoPunks attributes) | Mining timing/historical significance|
| Energy Use | Lower (PoS blockchains) | Higher (Bitcoin’s PoW) |
Controversies and Challenges
Block Space and Fees
- Criticism: Ordinals may congest blocks, raising transaction fees and deviating from Bitcoin’s payment-focused ethos.
- Counterpoint: They diversify Bitcoin’s utility without altering its core protocol.
Bitcoin’s Identity Debate
- Purists: Argue Ordinals dilute Bitcoin’s original vision as "digital gold."
- Innovators: View Ordinals as expanding Bitcoin’s use cases (e.g., digital art, collectibles).
The Ordinals Ecosystem
- BRC-20 Tokens: Bitcoin’s answer to ERC-20, enabling fungible tokens via Ordinals.
- Rare/Exotic Satoshis: Satoshis tied to historic events (e.g., mined by Satoshi Nakamoto, Pizza Day transactions).
- Marketplaces: Platforms like Magic Eden and OKX facilitate Ordinals trading.
How to Buy Bitcoin Ordinals
Step-by-Step Guide
- Set Up a Bitcoin Wallet: Use a Taproot-compatible wallet (e.g., Sparrow Wallet).
- Fund Your Wallet: Deposit BTC to cover inscription fees.
- Choose a Marketplace: Browse collections on Magic Eden or OKX.
- Connect Wallet & Purchase: Select an Ordinal, confirm the transaction.

FAQs
1. Are Bitcoin Ordinals the same as NFTs?
Yes, but they’re fully on-chain (no external metadata) and derive rarity from Bitcoin’s mining history.
2. Why are Ordinals controversial?
They increase blockchain bloat and fees, sparking debates about Bitcoin’s primary use case.
3. Can I sell Ordinals like regular NFTs?
Yes, via marketplaces like Magic Eden, though liquidity is lower than Ethereum’s NFT markets.
4. What’s the cheapest way to inscribe an Ordinal?
Use tools like Gamma.io to batch inscriptions and reduce costs.
Bitcoin Ordinals merge the security of Bitcoin’s blockchain with the creativity of NFTs, offering a groundbreaking way to tokenize digital artifacts. While debates about their impact persist, their potential to redefine Bitcoin’s utility is undeniable.
