What are Bitcoin Ordinals? All You Need to Know

Bitcoin Ordinals have emerged as a game-changer in the cryptocurrency landscape, marking a significant revolution in the public blockchain space. This innovative approach to creating non-fungible tokens (NFTs) directly on the Bitcoin network, pioneered by developer Casey Rodarmor in January 2023, has opened up exciting possibilities for leveraging Bitcoin's robust security and immutability for a whole new category of digital assets.

While the concept of Bitcoin-based NFTs isn't entirely new, with established layer-2 networks like Counterparty, Stacks, and RSK paving the way, Ordinal NFTs introduce a fundamentally distinct architecture. Unlike their predecessors, Ordinals are not built on top of Bitcoin but rather inscribed directly onto the Bitcoin blockchain itself, utilizing the inherent properties of Bitcoin transactions to create unique and immutable NFTs. This direct inscription eliminates the need for additional layers and associated complexities, resulting in a more streamlined and secure NFT experience.

While the recent emergence of Ordinals has ignited renewed interest in NFTs on Bitcoin, the concept of rNFTs dates back further, with innovative projects already showcasing their potential. Notably, Sovryn, a decentralized exchange platform built on the RSK sidechain, successfully utilized native RSK NFTs in 2021 for its genesis sale and subsequent token sales. These NFTs served a dual purpose:

1. Access: Investors in the token sale were granted rNFTs that functioned as exclusive passes, allowing them to participate in the sale and become early supporters of the project. These NFTs provided a unique and verifiable record of their involvement in this crucial stage of Sovryn's development.

2. Community Building: The rNFTs also fostered a sense of community and belonging. Owning an rNFT served as a badge of honor, signifying participation in a groundbreaking initiative and connecting holders with other early adopters.

This example showcases the versatility of Ordinals and their potential to revolutionize how we interact with and utilize digital assets within the Bitcoin ecosystem.

By leveraging the inherent strengths of the Bitcoin network, Ordinals has opened doors to exciting possibilities for developers and creators alike. Whether it's creating collectible digital art, securing intellectual property rights, or facilitating fractional ownership of real-world assets, the potential applications for Ordinals are vast and far-reaching. As the technology continues to evolve and garner adoption, we can expect to witness an explosion of innovative use cases that will further solidify Bitcoin's position as a leading platform for the future of digital assets.

Since their debut, the community has eagerly embraced this innovation, minting over 50M+ ordinal NFTs and signaling a growing excitement among users, developers, and enthusiasts. But what sets ordinal NFTs apart from the rest? How do they function, and why has the Bitcoin community rallied around them? Join us on this journey as we unravel the mysteries behind ordinal NFTs, exploring their origins, mechanics, and the vibrant debate surrounding their significance in the ever-evolving landscape of blockchain and digital assets.

What are Ordinal Inscriptions?

Bitcoin Ordinals are the equivalent of non-fungible tokens on the Bitcoin blockchain using satoshis, the smallest denomination on the chain. Ordinals is a numbering scheme that allows tracking of individual satoshis. 100 million satoshis are made of one Bitcoin.

Each satoshi receives a serial number determined by the sequence of its mining. These serial numbers, known as ordinals, play a crucial role in the blockchain's ability to monitor the location and ownership of every satoshi. Ordinals also offer the possibility of adding extra content through a procedure known as inscribing.

Through the Ordinal protocol, it becomes feasible to generate distinctive and limited digital assets, like non-fungible tokens (NFTs), by appending additional data, such as images or text, to a satoshi. These assets leverage the security and decentralized nature of Bitcoin's blockchain. The Ordinals software for the Bitcoin mainnet was unveiled in January 2023.

The Prehistory of Bitcoin NFTs: Exploring the Roots Before Ordinals

While the recent rise of Ordinals has brought Bitcoin NFTs to the forefront of the crypto scene, the history of non-fungible tokens on the Bitcoin network extends much further back. Early attempts at creating NFTs on Bitcoin predate the very term itself.

One of the earliest and most significant projects in this space was Colored Coins, launched in 2012. This protocol allowed users to "color" individual bitcoins with metadata, essentially marking them as unique and distinct from other bitcoins. This enabled the creation of "colored coins" that represented various assets like real estate, stocks, or even collectibles. While not technically NFTs in the modern sense due to limitations in functionality and smart contracts, Colored Coins laid the groundwork for future developments in Bitcoin NFTs.

Another notable project from this era was Counterparty, which emerged in 2014. Built on top of the Bitcoin protocol, Counterparty enabled the creation of custom tokens and assets, further expanding the possibilities for non-fungible tokens on Bitcoin. While it encountered challenges related to scalability and user experience, Counterparty demonstrated the potential for Bitcoin to host a diverse range of digital assets.

These early projects, along with others like Omni Layer and Rootstock, paved the way for the emergence of Ordinals in 2023. By leveraging advancements in the Bitcoin protocol, such as Segregated Witness (SegWit) and Taproot, Ordinals made it possible to directly inscribe data onto individual satoshis, the smallest units of Bitcoin. This innovation opened the door to a new wave of Bitcoin NFTs, with Ordinals offering a unique approach to non-fungible tokens on the most secure and decentralized blockchain network.

Ordinal Wallets

An Ordinals Wallet is a noncustodial Bitcoin wallet designed for users to access, store, purchase, sell, and trade Bitcoin Ordinals.

To engage with the Ordinals protocol, it's essential to use a Bitcoin wallet equipped with a Taproot wallet address and "coin control." The Ordinals Wallet is among the select few that provide support for these features while still facilitating regular Bitcoin transactions. It serves as a dedicated tool for managing Bitcoin Ordinals and offers a comprehensive set of functionalities for users within the Ordinals ecosystem.

How Does Ordinal Work?

“Ordinals” and “Inscriptions” are both used to refer to this new type of Bitcoin NFT. To grasp the inner workings of ordinal NFTs, it's crucial to distinguish between the terms.

Ordinals serve as a system for arranging sats in a manner that establishes the "non-fungible" quality essential for NFT creation. On the other hand, inscriptions encompass the content of the ordinal NFT itself, encompassing elements like images, text, videos, or any other user-deemed data synonymous with an NFT.

Understanding these NFTs is facilitated by drawing parallels with non-Bitcoin NFTs, characterized by their uniqueness and the presence of two main components: tokenID and metadata.

TokenID distinguishes non-fungible tokens from each other, providing a unique barcode for each NFT, rendering them functionally distinct. The Ordinal theory serves a similar purpose as TokenID.

Bitcoin, inherently fungible, lacks a built-in mechanism for differentiation. Ordinal NFTs introduce ordinal theory as an innovative solution, assigning a unique number to each satoshi. Essentially, each ordinal represents a satoshi with a distinct number, and the process involves numbering individual satoshis based on the order of their mining.

The groundbreaking aspect of ordinal NFTs lies in this numbering system, creating a unique ID for every satoshi on the Bitcoin blockchain. The ordinal theory maintains order, preserving the sequence in which satoshis are mined through a first-in, first-out system based on transaction order. This innovation brings a new dimension to the concept of non-fungibility within the Bitcoin ecosystem.

Ordinal theory, at its core, does not contradict the fungible nature of Bitcoin. The Bitcoin protocol itself does not officially endorse the unique ordering of satoshis introduced by ordinal enthusiasts. Instead, a community of ordinal enthusiasts has chosen to collectively attribute significance to this numbering system and has developed tools that acknowledge and respect it.

Metadata

Moving on to metadata, a concept prevalent in non-Bitcoin blockchains, it involves the optional attachment of arbitrary data to non-fungible tokens. This feature is utilized to represent a diverse array of assets such as art, in-game items, profile pictures, financial assets, and more—elements that have become synonymous with the term "NFT."

Inscriptions as Metadata

There isn't a designated space for metadata as seen in non-Bitcoin counterparts. Instead, the metadata for ordinal NFTs resides within the witness data of a transaction. This is where the term "inscription" originates—the data linked to a specific satoshi is "inscribed" within the particular section of a Bitcoin transaction.

To create an ordinal NFT, users need to send a transaction of an individual satoshi to a Taproot-compatible wallet like Sparrow Wallet, Wasabi Wallet, or Specter Desktop and attach the desired metadata as part of the transaction. Users must consider the transaction's order to ensure that the intended satoshi is not utilized as a network fee. Automated tools like Ordinalsbot and Gamma have been developed to streamline this process, mitigating risks and making it more accessible for non-technical users. This approach ensures a smoother experience in creating ordinal NFTs within the Bitcoin ecosystem.

Ordinals Bitcoin Vs. NFTs

The primary distinction between Bitcoin Ordinals and traditional NFTs lies in the method of storing token-related data. Traditional NFTs on other crypto networks typically incorporate metadata or a URL pointer, directing to off-chain data. In contrast, Ordinals utilize inscriptions to store content directly on the blockchain. The aim is to enhance the decentralization and censorship resistance of Ordinals, but this approach also results in higher costs and limitations in size.

Another notable difference is in how rarity and value are determined. While traditional NFTs often rely on artwork attributes or supply scarcity, Bitcoin Ordinals introduce additional factors. The pricing of Ordinals may eventually hinge on key moments in Bitcoin's history associated with specific satoshis. For instance, the first Ordinal inscribed on a new block, a new adjustment period, or a new halving epoch could be deemed rarer and more valuable.

Here's a breakdown of the established rarity levels in Ordinal inscriptions:

• Common: Any satoshi that is not the first sat of its block.
• Uncommon: The first SAT of each block.
• Rare: The first SAT of each difficulty adjustment period.
• Epic: The first SAT of each halving epoch.
• Legendary: The first SAT of each cycle.

To navigate this complex landscape of rarity, collectors have access to various tools and resources. Platforms like Ordinals Explorer (https://ordiscan.com/) and Ordinal Tools (https://ordinalsdirectory.com/) offer comprehensive information on Ordinals, including rarity scores, historical data, and transaction details.

For those seeking to delve deeper into the world of Ordinal rarity, here are some additional resources:

• Ordinals Discord: (https://discord.com/channels/987504378242007100/1071168059160674475)

Lastly, the process of adding these NFTs to their respective blockchain networks varies. Bitcoin Ordinals employ Proof of Work (PoW) in the mining process, contributing to the substantial energy requirements of the Bitcoin network. In contrast, NFTs on chains using Proof of Stake (PoS) consume less energy and operate at a faster pace. This divergence in the underlying mechanisms adds another layer to the comparison between Bitcoin Ordinals and traditional NFTs.

Bottom Line

The Ordinals protocol has introduced an additional avenue for issuing alternative digital assets on the Bitcoin blockchain. Since its inception, it has been a topic of controversy, with at least one developer asserting that there isn't a straightforward and principled method for Bitcoin users to eliminate this functionality.

While its primary use has been for issuing NFTs initially, it remains an area worth monitoring for potential new applications. The influence of Ordinals on Bitcoin's fees, in the long run, will hinge on the level of popularity these new assets attain. It introduces an intriguing dynamic that could shape the landscape of digital assets on the Bitcoin blockchain.
