Until very recently, Bitcoin was thought to be digital gold (in terms of security, reliability and a means to transfer value). Compared to Ethereum (and other platforms designed to use Smart Contracts), Bitcoin was not a platform for NFTs or advanced DApps. However, this all began to change in 2023 with the invention of Bitcoin Ordinals, which have changed Bitcoin into an art gallery of digital artifacts.
Suddenly, images, music, text, and even full applications began appearing directly on Bitcoin. This caused excitement and controversy amongst users of the platform, leading them to produce more activity on the network than ever before. According to Ordinals creator Casey Rodarmor, “digital artifacts” are assets that are 100% on-chain (this means they are also secured as part of the Bitcoin blockchain). Regardless of whether Ordinals are being viewed as innovative or disruptive, they have had an exponential impact on the direction of the future and how we define what Bitcoin means in the present.
What Are Bitcoin Ordinals?
Bitcoin Ordinals is a protocol that is available to help distinguish, track, and inscribe on-chain data (like text, images, videos, etc.) to a single Satoshi (the smallest unit of Bitcoin equal to 0.00000001 BTC). By doing so, they are also creating a way for Satoshis to be used as digital collectibles (similar to NFTs). However, while traditional NFTs typically have their content stored off-chain on things like IPFS, with Bitcoin Ordinals, all of the data is stored directly on the Bitcoin blockchain; therefore, it is all truly on-chain and very durable.
Bitcoin Ordinals brought NFTs to Bitcoin without altering the underlying protocol of the network, which is one of the largest advances in Bitcoin history.
How do Bitcoin Ordinals work?
The two main components Bitcoin Ordinals rely on are ordinal theory and inscriptions.
The analytical method of identifying satoshis is based on their unique numbering system through ordinal numbers created sequentially according to the time of their retrieval. This identifier will allow for the separation of a specific satoshi from all other satoshis for some period throughout the life of the transaction.
Inscriptions use SegWit and Taproot’s upgrade of Bitcoin to add information directly to a satoshi. This new method of storing information was first introduced with the Taproot launch in late 2021. Once this information is placed onto the satoshi, the satoshi is permanently secured on the Bitcoin blockchain.
Using Bitcoin Ordinals, people can store and move digital assets on the Bitcoin network in a fully on-chain form, opening the door for Bitcoin to be more than just a payment method.
Why did Ordinals emerge on Bitcoin?
Ordinals became possible due to key Bitcoin upgrades. The SegWit upgrade in 2017 allowed blocks to operate more efficiently by changing how data is stored. The Taproot upgrade allowed for better programmability, privacy of data and improved the way that data could be used with Bitcoin.
These improvements laid the technical groundwork for the creation of inscriptions without changing the consensus rules in relation to Bitcoin.
The timing of these changes was also significant. As interest in NFTs matured past the initial hype of speculation, developers began looking for a permanent place to store NFTs where they would be secure. Bitcoin has never been matched in terms of being a decentralized network that is secure; therefore, it was the best choice to use as a location for NFTs.
In 2023, Ordinals drove a ton of activity on the Bitcoin network. At times, the inscription transactions comprised as much as 40% of all the transactions on Bitcoin.
Bitcoin Ordinals vs. Traditional NFTs
Both NFTs and Ordinals serve similar purposes; however, the two technologies have fundamental differences in their design. In typical cases, an NFT on Ethereum or traditional EVM-compatible networks stores the NFT’s ownership on-chain, while hosting its media off-chain. In contrast, an Ordinal attaches the entire asset directly into Bitcoin’s blockchain.
Thus, Ordinals are considerably more resilient against censorship and offer more long-term permanence; however, Ordinals use more block space and have a higher cost of transaction fees. Moreover, unlike NFTs on Ethereum, there are no native smart contracts to Ordinals, making them easier to create but also less programmable.
Ordinals are deemed to have a minimalist and Bitcoin-native approach to NFTs, which synergizes with Bitcoin’s underlying principles of permanence and security.
Impact on the bitcoin ecosystem
The emergence of Bitcoin Ordinals has changed how people use the network. Ordinals have allowed artists, collectors, developers, and those interested in NFTs all to join the Bitcoin ecosystem, thereby expanding the network’s use as more than just a form of payment or store of value.
Additionally, Ordinals have provided more revenue for miners through higher transaction fees. Inscription- driven activity was a key factor in many fee spikes during peak times throughout 2023-2024, which is significant since we are approaching the era of lower block rewards due to halvings.
However, Ordinals have sparked debates.Some bitcoin purists argue that allowing non-monetary items to clutter up the Bitcoin network goes against what Bitcoin was designed to do. On the opposite side of the argument, many people think that the growth of the Ordinals will actually strengthen the sustainability of the Bitcoin network because it allows for additional functionality and use.
As MicroStrategy’s Chairman, Michael Saylor, stated, Ordinals are “a catalyst for innovation” and bring “new applications and adoption” to the Bitcoin ecosystem.
Real-world uses of Bitcoin Ordinals
Digital art, collectibles, music, documents, & software are all examples where we find Ordinals being used daily. Even entire games & applications have been written & stored in an Ordinal format within the Bitcoin blockchain, showcasing the creative possibilities of this protocol.
Aside from being beneficial to the development of BRC-20 tokens – a new token standard that uses Ordinals to create inscriptions. Ordinals have also played a significant role in expanding Bitcoin’s use and attracting a lot of new users and developers.
Platforms like Magic Eden, OKX, and UniSat now support Ordinals trading, signaling growing mainstream integration.
Challenges and limitations
Although Ordinals are innovative, they do present challenges when it comes to continued use. When more users and developers use them, they create a larger demand for block space that could result in higher transaction fees and longer confirmation times, especially during high traffic periods. Compatibility with wallets and the user experience for Ordinals continue to develop, making them less accessible to newcomers than NFTs on Ethereum.
That said, there has been considerable investment being made into the infrastructure of the ecosystem, upcoming improvements in wallets, marketplaces, and developer tools.
The future of Bitcoin Ordinals
Bitcoin Ordinals are redefining what’s possible on the Bitcoin network. The development of Layer-2 protocols such as the Lighting Network and new ways to scale the Bitcoin blockchain are anticipated to result in an efficient ecosystem capable of supporting an increasing volume of transactions.
As major businesses and service providers embrace the Ordinals, the view that the Bitcoin Network is evolving from merely being seen as a digital currency to being an essential base for long-term ownership and permanence of goods will continue to grow.
Conclusion
The total transformation of how the bitcoin blockchain utilizes Bitcoin Ordinals is majorly due to the enabled on-chain, digital assets. As such, Bitcoin’s scope and uses have expanded significantly; it has gone from simply being used as a secure payment network to having an important function as an immutable digital ownership platform. While debates about their long-term impact continue, their influence is undeniable. To understand Bitcoin Ordinals, you must also understand the next chapter of bitcoin involving how security, scarcity, and creativity unite on the most trusted blockchain globally.
