Meta: Learn how Bitcoin Ordinals are changing the NFT space using Sats and the Taproot upgrade. Discover how they work and why they matter.

In the last decade, blockchain technology has facilitated innovations such as NFTs. Non-fungible tokens, or NFTs for short, are the rave of the moment. In fact, the revenue in the NFT market is projected to reach US$2,378.0m in 2024. 

NFTs are digital assets that can represent unique content. This includes art, music, collectibles, and games. Recently, NFTs have boomed in popularity, with some digital artworks selling for millions of dollars.

NFTs are created and utilized on blockchain networks that support smart contracts. NFTs first exploded on Ethereum due to the platform’s flexibility, innovation, and popularity. It began in 2017 with a project called CryptoPunk.

The smart contracts support made Ethereum a large platform for developers, artists, and collectors to create massive NFT projects and collections such as the popular CryptoPunks, CryptoKitties, and Axie Infinity.

Recently, NFTs experienced a boom on the Bitcoin platform due to recent upgrades such as the Taproot upgrade. This upgrade enabled data encryption and signature aggregation, making Bitcoin ordinals more private and efficient.

What are Bitcoin Ordinals?

The idea was developed in 2022 and launched in 2023 as an NFT variation. Simply put, they are the basic units of Bitcoin, also known as Satoshis or Sats. Sats are the smallest Bitcoin unit and each one is mined and integrated with a unique serial number. This serial number is known as the ordinal. This means each Sat is different from the other and can be tracked and transferred.

In 2022, Casey Rodarmor inscribed the first ordinal. Later in 2023, the functionalities of sats were expanded to include the inscription of additional content such as text, visual images, or code. This innovation made it possible for Sats to be used similarly as an NFT. 

In the past, the only way to generate NFTs on the Bitcoin blockchain was by using third-party protocols or platforms relying on sidechains.  However, with this inscription process, Bitcoin Ordinals can benefit from Bitcoin’s blockchain security and decentralization, while remaining on the Bitcoin blockchain.

How They Work

Bitcoin Ordinals are inscribed sats, which are the smallest Bitcoin unit Sats are equivalent to 0.00000001 BTC. Initially, each Sat only had 80 bytes to space for data inscription using the OP_RETURN function. The OP_RETURN is an opcode that marks the output and allows it to carry some data. 

To overcome size challenges, there were two major additions, SegWit and Taproot. SegWit made it possible to increase the size limit to 4mb, while Taproot enabled the combination of multiple Bitcoin transactions, thereby increasing transaction speed. 

The content or data on individual sats remain permanently on the Bitcoin blockchain after the transaction is mined. While the ordinals establish a serial number to track each sat, the inscriptions are used to store various data types. One of the most popular uses of Bitcoin ordinals is the creation of digital collectibles.

Bitcoin Ordinals vs NFTs

While Bitcoin ordinals function similarly to traditional NFTs, there are some fundamental differences. Below are the major differences between Bitcoin ordinals and NFTs.

  1. Inscription: Bitcoin ordinals are created using inscriptions, i.e. existing Sats are modified to include various content types. For traditional NFTs, the tokens are created completely new on various blockchain networks. Thus, they need data from outside sources for proper function.

Also, the file data in NFTs can be hosted anywhere. Bitcoin ordinals however store the raw data directly on the Bitcoin blockchain. 

  1. Size: Bitcoin ordinals are limited to 4mb per inscription,  while Ethereum NFTs for example have a maximum storage size of 100mb.
  2. Format: NFTs are stored using standard formats or protocols such as ERC-721 or ERC-1155. Metadata is then created to store information about each NFT whenever they are created. On the other hand, Bitcoin ordinals can have customized formats or protocols. The need for metadata is removed as the data is included in the blockchain.
  3. Security: Bitcoin ordinal transactions are immutable due to the security and simplicity of the Bitcoin blockchain. Once each transaction has been confirmed, it has a permanent record on the blockchain. NFTs however rely on third-party platforms and protocols to function properly, which can compromise the security of NFT assets. 
  4. Smart contract functionality: Unlike Ethereum, Bitcoin does not have smart contract functionality. This means the lack of decentralized exchanges and efficient UI can make it difficult to trade Bitcoin ordinals. 

However, you can trade Bitcoin ordinals over the counter. Ethereum NFTs on the other hand are stored on centralized third-party servers and employ smart contracts.
