Introduction
When Bitcoin launched in 2009, it revolutionized decentralized transactions by enabling peer-to-peer exchanges without intermediaries. However, Ethereum's dominance in the NFT market left Bitcoin enthusiasts seeking ways to integrate NFTs directly on the Bitcoin network. Enter ordinals, introduced by Casey Rodarmor, enabling NFT creation on Bitcoin. While innovative, ordinals faced limitations due to Bitcoin's 4 MB block size cap.
The solution? Recursive inscriptions, introduced in June 2023, which allow complex software to run on Bitcoin's blockchain by daisy-chaining data through calls. This breakthrough enhances scalability, reduces fees, and supports efficient on-chain storage for smart contracts.
In this guide, we’ll explore:
- The evolution of ordinals and their impact.
- How recursive inscriptions work.
- Their potential to transform Bitcoin’s capabilities.
TL;DR
- Ordinals enable NFT-like inscriptions on Bitcoin but are limited by the 4 MB block size.
- Recursive inscriptions bypass this limit by linking data across existing inscriptions.
- Benefits include reduced fees, scalable storage, and advanced smart contracts on Bitcoin.
- Controversy exists around ordinals, with debates over their alignment with Bitcoin’s principles.
What Are Ordinals?
Ordinals number and track individual satoshis (the smallest Bitcoin unit), categorizing them by rarity:
| Rarity Level | Description |
|-------------------|-----------------------------------------------------------------------------|
| Common | Satoshis not first in their block. |
| Uncommon | First satoshis of each block. |
| Rare | First satoshi of Bitcoin’s difficulty adjustment period (every 2016 blocks). |
| Epic | First satoshis of each halving epoch (~every 4 years). |
| Legendary | First satoshi of each market cycle between halvings. |
| Mythic | First satoshis of the Genesis block (rarest). |

A Brief History of Ordinals
- February 2022: Concept introduced by Casey Rodarmor.
- January 2023: Officially launched.
- March 2024: Over 60 million ordinals minted, with growing daily inscriptions.
What Are Recursive Inscriptions?
Recursive inscriptions break the 4 MB limit by referencing existing inscriptions to build interconnected data networks. For example:
- A 3D NFT under 1 KB (e.g., OnChainMonkey) can reference larger datasets stored elsewhere on the blockchain.
- Developers can run on-chain software by daisy-chaining data calls.
Advantages:
- Scalability: Host large files (games, movies) directly on Bitcoin.
- Cost Efficiency: Reduces storage duplication and transaction fees.
How Do Recursive Inscriptions Work?
- Find Existing Inscriptions: Use tools like ordiscan to locate source code.
- Modify Code: Edit the HTML in an editor (e.g., GitHub template).
- Inscribe: Upload the new data, referencing prior inscriptions.
Future of Recursive Inscriptions
Challenges:
- Limited documentation and centralized dependency on ordinal theory developers.
- Early-stage adoption with unproven long-term efficiency.
Opportunities:
- Permissionless contracts enforced by Bitcoin’s blockchain.
- Expanded use cases for Bitcoin as a storage and computation layer.
FAQ
Q: What are ordinals on Bitcoin?
A: Ordinals number satoshis to inscribe NFTs/data directly on Bitcoin.
Q: How do recursive inscriptions improve storage?
A: They minimize data duplication by layering references to existing inscriptions.
Q: Why are ordinals controversial?
A: Critics argue they complicate Bitcoin’s simplicity and may increase fees.
Final Thoughts
Recursive inscriptions unlock Bitcoin’s potential for advanced applications, from large-file storage to smart contracts. While challenges remain, their ability to reduce costs and enhance scalability positions them as a key innovation in the ordinal ecosystem.
