Bitcoin is breaking new ground with Ordinals, a protocol that lets users inscribe data like text and images directly onto individual satoshis—the smallest Bitcoin units. This guide explores the mechanics of Ordinals, their implications for onchain storage, and their impact on Bitcoin collectibles.
What Are Ordinals and How Do They Work?
Bitcoin Ordinals is a protocol enabling the inscription of arbitrary data (e.g., text, images, videos) onto individual satoshis. These inscribed satoshis are often referred to as "Inscriptions" or "Bitcoin NFTs."
The Inscription Process:
- Data Inclusion: Data is embedded within a Bitcoin transaction’s witness field (used for transaction verification).
- Permanence: Once mined, the inscription becomes immutable and decentralized—just like any other Bitcoin blockchain data.
- Tracking: Ordinal theory allows tracking inscribed satoshis across transactions, enabling ownership transfers.

Key Features of Ordinals
Onchain Storage
Unlike many Ethereum NFTs that store metadata offchain (e.g., on IPFS), Ordinals are fully onchain due to Bitcoin’s transaction-based data storage. Benefits include:
- Lower costs: Cheaper than Ethereum’s onchain storage.
- Permanence: Best cost-to-permanence ratio in the NFT space.
BRC-20 Tokens
An experimental fungible token standard built via Inscriptions:
- How they work: JSON snippets inscribed into satoshis define token attributes (supply, ticker).
- Example: $ORDI surpassed a $1B market cap in 2023.
Rare Sats
Satoshis classified by rarity (Rodarmor Rarity Index):
- Categories: Mythic (genesis block), legendary, epic, rare.
- Historical Sats: Pizza Sats (first BTC commerce), Palindrome Sats (numerical symmetry).
Using Ordinals: Wallets and Marketplaces
Recommended Wallets:
- Xverse: Supports Ordinals/BRC-20s.
- Leather: Bitcoin-focused with NFT features.
- OKX Web3: Multi-chain marketplace integration.
Top Marketplaces:
- OKX Ordinals Market
- Magic Eden
- Gamma
Adoption and Controversy
Ordinals have sparked debate:
- Critics: Argue Bitcoin should remain payment-focused.
- Supporters: Praise innovation and miner fee revenue.

The Future of Ordinals
Opportunities:
- Expanding Bitcoin’s utility beyond payments.
- Driving miner fees post-halving.
Challenges:
- Network congestion from NFT mints.
- Scalability debates.
FAQ
1. Are Ordinals the same as Ethereum NFTs?
No—Ordinals are fully onchain and native to Bitcoin, whereas many Ethereum NFTs rely on offchain storage.
2. What’s the cheapest way to mint an Ordinal?
Costs depend on Bitcoin transaction fees. Inscriptions during low-traffic periods are cheaper.
3. Can Ordinals be transferred to Ethereum?
Not directly, but cross-chain bridges may emerge.
4. Why are Rare Sats valuable?
Their scarcity ties to Bitcoin’s history (e.g., genesis block satoshis).
5. How do I avoid losing an inscribed satoshi?
Use wallets with "sat control" to manage individual satoshis carefully.
Final Thought: Ordinals redefine Bitcoin’s possibilities, blending collectibles with blockchain’s security. Whether this becomes mainstream hinges on scaling solutions and community consensus.
