Ordinals NFT: The New Digital Artifacts on the Block(chain) - A Beginner's Guide

Ordinal theory represents a groundbreaking innovation in the Bitcoin ecosystem, introducing a novel method for creating ordinals NFT and digital artifacts directly on the Bitcoin blockchain. This technology enables individual satoshis—the smallest divisible units of Bitcoin—to be uniquely identified, tracked, and inscribed with immutable data, opening new possibilities for digital collectibles and on-chain applications.

TL;DR

Ordinal theory introduces a revolutionary numbering system for satoshis based on their mining and transfer order, creating unique identifiers for each unit. The inscription process allows users to embed permanent, immutable data onto individual satoshis, effectively creating Bitcoin-native ordinals NFT similar to traditional NFTs. Recursive inscriptions, launched in mid-2023, broke through previous data limitations by enabling interconnected data sources and complex on-chain applications. The market has responded positively, with Bitcoin ordinals NFT gaining significant traction and occasionally surpassing Ethereum in NFT sales during various periods. However, this innovation has created division within the Bitcoin community regarding its alignment with the network's original purpose and its impact on transaction fees and network capacity.

What is ordinal theory?

Ordinal theory establishes a comprehensive framework for numbering and tracking individual satoshis using sequential ordinal numbers. These numbers are systematically assigned based on the chronological order in which satoshis are mined and subsequently transferred through transactions on the Bitcoin network. The numbering system supports multiple representation formats, including integer, decimal, degree, and percentile notations, providing flexibility in how these unique identifiers are expressed.

A particularly innovative aspect of ordinal theory is its creation of rarity hierarchies for satoshis, which forms the foundation of ordinals NFT value. The rarity structure consists of six distinct tiers: Common satoshis are any that aren't the first in their block and comprise the vast majority of all sats. Uncommon satoshis are the first sat of each block, occurring approximately 144 times daily. Rare satoshis mark the beginning of difficulty adjustment periods, which happen every 2,016 blocks or roughly every two weeks. Epic satoshis inaugurate each halving epoch, occurring every 210,000 blocks or approximately every four years. Legendary satoshis represent the first sat of each complete market cycle spanning from one halving to the next. Finally, Mythic satoshis are extraordinarily unique, with only one existing—the first satoshi of the Genesis block. In late 2022, Casey Rodarmor, the creator of the Bitcoin ordinals protocol, inscribed pixel art of a skull as the genesis ordinal, creating the first and only mythic inscription.

The degree notation system provides an elegant method for representing ordinal numbers that immediately conveys a satoshi's rarity. This notation incorporates multiple dimensions of information including block height, difficulty adjustment period, halving epoch, and cycle information, allowing users to quickly assess the scarcity and significance of any particular satoshi.

How do ordinal inscriptions work?

Ordinal inscriptions function as a mechanism for permanently embedding digital content directly onto the Bitcoin blockchain, creating unique ordinals NFT analogous to traditional NFTs but constructed entirely within Bitcoin's native infrastructure without requiring separate tokens or sidechains. Users can inscribe various forms of digital content, such as videos, artwork, or text documents, onto individual satoshis, transforming them into immutable records.

The permanence of inscribed content represents one of its most valuable characteristics for ordinals NFT. Once data is inscribed onto the blockchain, it becomes an unalterable historical record that cannot be modified or deleted, ensuring authenticity and provenance. These inscribed satoshis can be transferred between Bitcoin addresses using standard Bitcoin transaction mechanisms, maintaining compatibility with existing infrastructure.

The technical foundation of inscriptions relies on ordinal theory principles, where each satoshi possesses a specific sequential order and value. This ordering requirement means that transactions involving inscribed satoshis must be carefully constructed to preserve the integrity of the ordinal numbering system. The actual content storage utilizes "taproot script-path spend scripts," an efficient and economical method for blockchain data storage introduced with Bitcoin's Taproot upgrade.

Inscribed content can be retrieved and displayed like regular web content and can even be combined with other inscriptions to create composite artifacts, enabling creative remixing possibilities. The inscription creation process involves a two-phase commit/reveal procedure: first, users create a taproot output that commits to a script containing the inscription content; second, they spend that output to reveal the content on-chain. The content and associated metadata are serialized using "envelopes," standardized wrappers that ensure other users can easily read and interpret the inscribed data.

How do I create an ordinal inscription?

The process of creating ordinals NFT accommodates users across various technical skill levels through multiple pathways. For beginners with limited or no coding experience, various platforms provide user-friendly interfaces that handle all technical complexities automatically. Users need only supply their creative content and imagination, with the platform managing the inscription process end-to-end.

Intermediate users comfortable with coding can explore the Ordinals API available on GitHub, maintained by Hiro, a company specializing in developer-friendly Bitcoin APIs. This option provides greater control and customization while offering support through an active developer community.

Advanced users who treat coding as a second language and possess deep understanding of ordinal theory rules can follow a comprehensive manual process. This begins with selecting and preparing the content for inscription, whether video, artwork, or text. Next, developers must create an envelope structure using editing or coding tools to wrap the content and metadata appropriately. The process continues with creating a taproot output using Bitcoin wallet software that supports the ordinals protocol, carefully ensuring the transaction adheres to ordinal theory rules.

After broadcasting the taproot output to the Bitcoin network, the inscription becomes "live" on the blockchain. The final step involves spending the taproot output to reveal the inscription content on-chain, making it publicly visible. Once complete, the inscription is permanently stored using taproot script-path spend scripts, guaranteeing immutability. Throughout this process, meticulous attention to ordinal theory rules is essential to ensure proper inscription creation and preservation of the ordinal numbering system.

The launch of recursive inscriptions

Mid-2023 marked a transformative milestone with the introduction of recursive inscriptions, representing a significant evolution in ordinals NFT capabilities. This innovation emerged as a solution to persistent challenges involving transaction fees and block space limitations that constrained earlier inscription implementations.

Recursive inscriptions enable sophisticated on-chain software execution directly on the Bitcoin blockchain, empowering developers to construct complex applications that operate entirely within Bitcoin's ecosystem. The technology employs a technique called daisy-chaining, where data elements are interconnected through sequences of calls, creating networks of related information.

Prior to recursive inscriptions, individual ordinals NFT were limited to 4MB of data storage. Recursive inscriptions transcend this constraint by allowing developers to establish interconnected webs of data sources. By extracting and integrating data from existing inscriptions into new ones, developers can effectively bypass the rigid 4MB limit. This breakthrough enables full on-chain software execution through linked data sequences.

The implications for Bitcoin network interoperability are substantial. Recursive inscriptions facilitate greater integration and communication between different on-chain elements, potentially expanding Bitcoin's utility beyond simple value transfer. This technology continues to evolve, offering new possibilities for ordinals NFT creators and developers.
