Bitcoin Ordinals

Last reviewed: June 29, 2026

Bitcoin Ordinals are a protocol that allows individual Satoshis, the smallest unit of Bitcoin, to be uniquely identified and tracked. This system enables the creation of non-fungible tokens (NFTs) on the Bitcoin [blockchain](/wiki/bitcoin_blockchain), similar to those on Ethereum. As of October 2023, Bitcoin Ordinals have gained attention for their potential to expand Bitcoin's functionality beyond a simple currency. The protocol introduces a new layer of utility to Bitcoin, allowing for the inscription of data onto individual Satoshis, thereby creating a form of digital artifact. This article explores how Bitcoin Ordinals work, their applications, their relationship to Tether (USDT), and their advantages and disadvantages.

Overview

Bitcoin Ordinals represent a protocol that enables the tracking and inscription of data onto individual Satoshis within the Bitcoin network. A Satoshi is the smallest unit of Bitcoin, equivalent to 0.00000001 BTC. The Ordinals protocol assigns a unique identifier to each Satoshi, allowing it to be distinguished from others. This capability transforms Bitcoin into a platform for creating NFTs, which are unique digital assets that can represent ownership of digital or physical items.

The concept of Bitcoin Ordinals was introduced to enhance the Bitcoin blockchain's utility by enabling the creation and transfer of NFTs directly on the network. Unlike traditional NFTs that rely on smart contract platforms like Ethereum, Bitcoin Ordinals operate natively on the Bitcoin blockchain without requiring additional layers or tokens. This integration offers a new dimension to Bitcoin's use cases, potentially increasing its adoption and value.

How it works

The Bitcoin Ordinals protocol functions by assigning a unique ordinal number to each Satoshi. This number is derived from the order in which the Satoshis are mined and transacted. The protocol uses a technique called "inscription" to attach data to these Satoshis, effectively creating a digital artifact. This data can include text, images, or other forms of digital content.

Inscription Process

The inscription process involves embedding data into the witness section of a Bitcoin transaction. The witness section is part of the transaction structure introduced by the Segregated Witness (SegWit) upgrade, which separates signature data from transaction data. By utilizing this section, Bitcoin Ordinals can inscribe data without increasing the transaction size significantly, thus maintaining network efficiency.

Tracking and Transfer

Once inscribed, the unique Satoshis can be tracked and transferred like any other Bitcoin transaction. The Ordinals protocol ensures that the data remains attached to the specific Satoshis as they move through the network. This tracking capability allows for the creation of a verifiable history of ownership and provenance for each digital artifact.

Applications

Bitcoin Ordinals open up several potential applications, primarily in the realm of digital collectibles and NFTs. By enabling the creation of NFTs on the Bitcoin blockchain, Ordinals provide a new avenue for artists, creators, and collectors to engage with digital assets.

Digital Art and Collectibles

Artists can use Bitcoin Ordinals to create and sell digital art pieces directly on the Bitcoin blockchain. Each piece can be inscribed onto a unique Satoshi, ensuring its authenticity and provenance. Collectors can purchase these digital artifacts, knowing they are acquiring a unique piece of art with a verifiable history.

Tokenized Assets

Beyond art, Bitcoin Ordinals can be used to tokenize physical assets, such as real estate or luxury goods. By inscribing ownership details onto a Satoshi, these assets can be represented and traded on the Bitcoin network, providing a secure and transparent method of ownership transfer.

Relationship to USDT

Tether (USDT) is a stablecoin that aims to maintain a 1:1 value with the US dollar. While Bitcoin Ordinals and USDT operate on different principles, there is a potential relationship between the two in terms of enhancing Bitcoin's utility.

Enhanced Bitcoin Utility

Bitcoin Ordinals enhance Bitcoin's utility by enabling NFT creation, while USDT provides a stable value transfer mechanism within the cryptocurrency ecosystem. Together, they can offer a more versatile platform for digital transactions, combining Bitcoin's security with USDT's stability.

Potential Integration

As of October 2023, there is no direct integration between Bitcoin Ordinals and USDT. However, the development of Ordinals could lead to future collaborations or integrations, where stablecoins like USDT are used in conjunction with NFTs on the Bitcoin blockchain.

Advantages and disadvantages

Bitcoin Ordinals offer several advantages and disadvantages that impact their adoption and use.

Advantages

- Native Bitcoin Integration: Ordinals operate directly on the Bitcoin blockchain, eliminating the need for additional layers or tokens.
- Enhanced Utility: By enabling NFT creation, Ordinals expand Bitcoin's use cases beyond a simple currency.
- Provenance and Authenticity: The protocol provides a verifiable history of ownership for digital artifacts.

Disadvantages

- Scalability Concerns: Increased data inscription could lead to network congestion and higher transaction fees.
- Complexity: The technical nature of Ordinals may pose challenges for users unfamiliar with Bitcoin's underlying technology.
- Market Adoption: As a relatively new concept, Bitcoin Ordinals may face hurdles in achieving widespread adoption.
