This is due to the limited smart contract functionality on Bitcoin, as well as the lack of an <strong>NFT token standard<\/strong> similar to Ethereum&#8217;s ERC-721.<\/p>\n\n\n\n<p>The history of Bitcoin NFTs dates back to 2012 with the launch of the <strong>Colored Coins protocol<\/strong>. Colored Coins were bitcoins with a special marker that distinguished them from standard bitcoins. They are considered the first step toward building NFTs on the Bitcoin network.<\/p>\n\n\n\n<p>Bitcoin NFTs recently regained interest with the launch of the <strong>Ordinals protocol<\/strong> in January 2023, which made it possible to mint NFTs directly onto the Bitcoin blockchain.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">What Is the Bitcoin Ordinals Protocol?<\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1067\" height=\"647\" src=\"https:\/\/metaverseplanet.net\/blog\/wp-content\/uploads\/2025\/08\/unnamed-edited.jpg\" alt=\"\" class=\"wp-image-25967\" srcset=\"https:\/\/metaverseplanet.net\/blog\/wp-content\/uploads\/2025\/08\/unnamed-edited.jpg 1067w, https:\/\/metaverseplanet.net\/blog\/wp-content\/uploads\/2025\/08\/unnamed-edited-300x182.jpg 300w, https:\/\/metaverseplanet.net\/blog\/wp-content\/uploads\/2025\/08\/unnamed-edited-1024x621.jpg 1024w, https:\/\/metaverseplanet.net\/blog\/wp-content\/uploads\/2025\/08\/unnamed-edited-768x466.jpg 768w, https:\/\/metaverseplanet.net\/blog\/wp-content\/uploads\/2025\/08\/unnamed-edited-150x91.jpg 150w\" sizes=\"(max-width: 1067px) 100vw, 1067px\" \/><\/figure>\n\n\n\n<p>Because of their innovative nature, Bitcoin Ordinals <strong><em><a href=\"https:\/\/metaverseplanet.net\/blog\/understanding-giants-in-nfts-a-complete-guide\/\" data-type=\"post\" data-id=\"20211\">NFTs<\/a><\/em><\/strong> involve several technical terms. To better understand how the Ordinals protocol works, let&#8217;s start with a brief explanation of the terminology.<\/p>\n\n\n\n<p><strong>Bitcoin Ordinals NFTs<\/strong> are based on <strong>Ordinal theory<\/strong> and the <strong>Ordinals protocol<\/strong>, developed by Casey Rodarmor. The goal of Ordinal theory is to give each <strong>satoshi<\/strong> (the smallest unit of Bitcoin) an individual identity, allowing it to be tracked, transferred, and inscribed with unique meaning. This makes one satoshi different from another, and therefore, <strong>non-fungible<\/strong>.<\/p>\n\n\n\n<p>The core ideas of Ordinal theory and the Ordinals protocol include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The Ordinals protocol assigns a sequential number to each satoshi. To be precise, each satoshi is numbered in the order in which it was mined (e.g., the first satoshi ever minted is number one).<\/li>\n\n\n\n<li>Next, each satoshi can be inscribed with data, such as images, text, or videos, through a Bitcoin transaction. The size of the inscription can be up to 4MB.<\/li>\n\n\n\n<li>Once the transaction is mined, the recorded data is a permanent part of the Bitcoin blockchain. It can also be viewed through Ordinals-enabled Bitcoin wallets and online Ordinals viewers. For example, a CryptoPunk image from the Ordinals web site can be viewed.<\/li>\n<\/ul>\n\n\n\n<p>In short, each satoshi\u2019s <strong>token ID<\/strong> is its sequential number, while an Ordinals NFT\u2019s metadata is its <strong>inscription<\/strong>, which is held within a transaction&#8217;s witness data.<\/p>\n\n\n\n<p>The primary advantage of Ordinals NFTs compared to NFTs on other blockchains is that <strong>all metadata resides on the Bitcoin blockchain itself<\/strong>. In other words, Ordinals NFTs exist directly on the Bitcoin blockchain, not on a separate layer. This is seen by many as providing a higher level of immutability. In contrast, for many NFT collections on other blockchains, the actual image file of the art is typically stored off-chain, and the metadata only contains a link to the image file. This means the artwork could potentially be altered by third parties if not stored on the blockchain.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Other Developments in Bitcoin NFTs<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"850\" height=\"510\" src=\"https:\/\/metaverseplanet.net\/blog\/wp-content\/uploads\/2025\/06\/Polygon-NFT-Sales-Hit-Record-1.jpg\" alt=\"\" class=\"wp-image-23196\" srcset=\"https:\/\/metaverseplanet.net\/blog\/wp-content\/uploads\/2025\/06\/Polygon-NFT-Sales-Hit-Record-1.jpg 850w, https:\/\/metaverseplanet.net\/blog\/wp-content\/uploads\/2025\/06\/Polygon-NFT-Sales-Hit-Record-1-300x180.jpg 300w, https:\/\/metaverseplanet.net\/blog\/wp-content\/uploads\/2025\/06\/Polygon-NFT-Sales-Hit-Record-1-768x461.jpg 768w, https:\/\/metaverseplanet.net\/blog\/wp-content\/uploads\/2025\/06\/Polygon-NFT-Sales-Hit-Record-1-150x90.jpg 150w\" sizes=\"(max-width: 850px) 100vw, 850px\" \/><\/figure>\n\n\n\n<p><strong>Bitcoin Stamps<\/strong> (Securely Timed and Protected Art) is another recent protocol that offers a different method for embedding image data into Bitcoin compared to the Ordinals protocol.<\/p>\n\n\n\n<p>Bitcoin Stamps NFTs are similar to ERC-1155 semi-fungible tokens or digital collectibles, but instead of witness data like Ordinals, they are stored in Bitcoin&#8217;s <strong>unspent transaction outputs (UTXOs)<\/strong>. UTXOs are records of unspent bitcoins resulting from transactions between two addresses. The way the Bitcoin Stamps protocol stores metadata makes it impossible for a full node to prune (i.e., remove the data), which helps to ensure the data is preserved immutably.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Ordinals vs. Bitcoin Stamps<\/h2>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-fixed-layout\"><thead><tr><td><\/td><td><strong>Ordinals<\/strong><\/td><td><strong>Stamps<\/strong><\/td><\/tr><\/thead><tbody><tr><td><strong>Pros<\/strong><\/td><td>Stores image data within prunable transaction witness data, resulting in a lower cost to mint NFTs compared to Stamps (which stores data in many different UTXOs).<\/td><td>Image data cannot be pruned from a full node since it is stored in many different UTXOs.

Ordinal Punks uses an open-source algorithm to generate the 192&#215;192 pixel PFPs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">TwelveFold<\/h3>\n\n\n\n<p>Even major NFT brands are joining the Ordinals movement. Yuga Labs, the company behind the top Ethereum-based NFT collection <strong>Bored Ape Yacht Club<\/strong>, recently launched its first Bitcoin Ordinals NFT collection, named <strong>TwelveFold<\/strong>.

It was created in March 2023 by an anonymous on-chain analyst named &#8220;domo.&#8221; Inspired by Ethereum&#8217;s <strong>ERC-20<\/strong>, BRC-20 tokens allow developers to create and transfer fungible tokens using the Ordinals protocol. However, unlike ERC-20, BRC-20 tokens do not leverage smart contracts.<\/p>\n\n\n\n<p>The BRC-20 token standard uses Ordinals inscriptions of JSON data to deploy, mint, and transfer tokens. Currently, over <strong>34,000 BRC-20 tokens<\/strong> have been minted, including the first BRC-20 token, <strong>ORDI<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Conclusion<\/h3>\n\n\n\n<p><strong>Bitcoin NFTs<\/strong> have seen a significant increase in popularity since the launch of the <strong>Ordinals protocol<\/strong> in January 2023, which made it possible to mint NFTs directly onto the Bitcoin blockchain.<\/p>\n\n\n\n<p><strong>Bitcoin Ordinals NFTs<\/strong> are based on Ordinal theory, which aims to give each satoshi a unique identity, allowing them to be tracked, transferred, and imbued with individual meaning through inscriptions.
