Backing up your digital artifacts and NFTs on Bitcoin

Artifacts, Ordinals, Inscriptions, and BRC-20


Introduction to Ordinals

In this article, we'll explore how Ordinals are used in the Bitcoin ecosystem to create a new type of NFT. Our intention is to provide practical information for creators, collectors, and all marketplace participants interested in engaging with Ordinals on Bitcoin.

We'll start with a high-level explanation of Ordinals and NFTs on Bitcoin, highlighting their characteristics and potential uses. Then we'll delve into BRC-20, the token standard for these digital artifacts, and how it differs from tokens on other blockchains. We'll touch on some controversies. And lastly, we'll review a few important considerations for protection and inheritance in order to to ensure the longevity of these assets.

Understanding NFTs on Bitcoin requires a shift in perspective from NFTs on blockchains like Ethereum, Solana, Avalanche, Polygon, and Cardano. For example, Ordinal-inscribed Bitcoin satoshis have both fungible (interchangeable) and non-fungible (unique) properties. Bitcoin Ordinals differ from ERC-721 NFT tokens in several technical ways, including how much data can be included, and where that data is stored.

But from the perspective of an artistic creator or collector, Bitcoin Ordinals deliver many of the same marketplace features that have been popularized by ethereum-based NFTs - with greater security and immutability.

What are Bitcoin Ordinals?

The Ordinal protocol is one of several new "features" of Bitcoin that followed the Taproot upgrade in November 2021.

In 2022, the Bitcoin Improvement Proposal for Ordinals brought the capability to inscribe arbitrary digital assets onto the Bitcoin blockchain. Recall that a satoshi is the smallest unit of Bitcoin -- so named after Bitcoin's pseudonymous creator, Satoshi Nakamoto. Using the Ordinals protocol, each satoshi can be ordered and "inscribed" with up to 4 MB of data that could include images, audio, code, or any other data.

Ordinals have been rapidly gaining in popularity. To date, there have been more than 60 million inscriptions added to satoshis on the Bitcoin blockchain. At times, users have inundated the network with an array of new content.

What are Bitcoin Artefacts / Artifacts?


Bitcoin artifacts are digital artifacts that were created on the Bitcoin blockchain. They may also be called Bitcoin NFTs.

The Ordinals documentation FAQ advocates for use of the term "digital artifact:"

An inscription is an NFT, but the term "digital artifact" is used instead, because it's simple, suggestive, and familiar.” -- Ordinals FAQ

Digital artifacts can take many forms, and commonly include memes, images, screenshots, audio clips, and snippets of code.

Bitcoin artifacts may seem limited given the 4MB data restriction per satoshi, but in June 2023, a new capability called Recursive Inscriptions allowed larger and more-complex data by supporting a series of calls that can pull in other inscription data already on the blockchain. Recursive Inscriptions theoretically allow the storage and use of on-chain data sufficient to store and interact with entire movies and video games!

Ordinals, NFTs, and fungibility

Recall that the term "NFT" stands for Non-Fungible Token, where "non-fungible" means that tokens of that type are not interchangeable ... instead, their value or characteristics vary (like Bored Ape NFTs).

Because an Ordinals inscription modifies a satoshi by inscribing data onto it, it's a little confusing to talk about whether that satoshi is then a fungible or non-fungible token because actually it has both characteristics. An inscribed satoshi can be spent like any other satoshi, so it is fungible. But its inscribed data could make it uniquely valuable so that the owner would not want to spend it like any other satoshi!

For the record, then, when we refer to putting NFTs on the Bitcoin blockchain, we are referring to the use of the Bitcoin Ordinals protocol to create non-fungible inscriptions on fungible tokens.

What is BRC-20?

In early 2023, right after the Ordinals protocol made Bitcoin NFTs an overnight sensation, the BRC-20 experimental token standard formally added Ordinal-inscribed token use cases to the Bitcoin base layer.

You can mint and transfer BRC-20 tokens in a similar way to Ethereum's ERC-20 NFTs. In fact, BRC-20 is in many ways similar to Ethereum's NFTs, however BRC-20 can not take advantage of the power and flexibility of Ethereum's smart contracts. As an example of a related limitation: although inscriptions themselves can not support token royalties, BRC-20 attempts to reduce this gap by offering a royalty capability, which has surely helped to drive its popularity.

What are the differences between Ethereum and Bitcoin NFTs?

Bitcoin Ordinals, as conceptualized by developer Casey Rodarmor, differ from traditional Ethereum-based NFTs in several key ways, even though both are forms of digital art. Rodarmor characterizes Bitcoin NFTs as "authentic digital artifacts" because they are fully on-chain and inherit the robust attributes of the Bitcoin network.

  1. Immutability: Bitcoin inscriptions are inherently immutable, unlike Ethereum-based NFTs which can potentially be altered or deleted by the contract owner. To achieve immutability of some NFTs necessitates auditing, a process that requires an in-depth understanding of the Ethereum Virtual Machine (EVM) and Solidity.
  2. On-chain Content: Bitcoin inscriptions consistently contain on-chain content, making them durable and resistant to loss. The creation of inscriptions entails fees proportional to the content size. Ethereum NFTs, in contrast, may have off-chain content stored on platforms such as IPFS, which can be lost.
  3. Security: Bitcoin inscriptions offer enhanced security given the superior security attributes of the Bitcoin blockchain. Also, they can be transferred using Partially Signed Bitcoin Transactions (PSBT) without necessitating the third-party intermediaries such as an exchanges or marketplaces that are required for some Ethereum NFT transfers.
  4. Smart Contracts: Bitcoin's BRC-20 tokens have more limited scripting capabilities than Ethereum's Turing-complete, ERC-20 Smart Contracts. However, the use of intricate smart contracts on Ethereum may pose a challenge for individuals unfamiliar with the technical aspects of digital art trading.

How can you put NFTs on Bitcoin?

There are web-based platforms like Ordinalbots that can make the process of putting NFTs onto the Bitcoin blockchain quite simple. But here is a high-level description of what's involved:

  1. Get a Taproot-capable wallet (such as Ordinals Wallet, Xverse, OKX, Hiro, or Unisat). While you are at it, get some Bitcoin to use for token minting and transaction fees.
  2. Create Your Digital Asset: This could be any digital item like an image, a piece of music, a digital art, etc. It's important to remember that the digital asset you create should be original and owned by you.
  3. Mint the BRC-20 NFT: 'Minting' is the process of turning your digital asset into a BRC-20 token / NFT. This can be done using various platforms that support the Bitcoin blockchain. This step will usually involve a small fee payable in Bitcoin.
  4. Store or Sell Your NFT: Once your NFT is minted, you can keep it in your digital wallet or sell it on a marketplace such as Magic Eden that supports Bitcoin NFTs.
  5. Transfer Ownership: If you sell your NFT, the ownership of the NFT will be transferred to the buyer. This transaction will be recorded on the Bitcoin blockchain, ensuring the authenticity and ownership of the NFT.

Remember, this is a simplified explanation, and the actual process can be a bit more complex depending on the platform you use and the specific requirements of your digital asset. Always do your own research or consult with a professional if you're unsure about anything.

What are some popular Bitcoin NFT projects?

The first BRC-20 token, ORDI, is still one of the most popular in this space.

A BRC-20 meme token called MICE became wildly popular in late 2023 after Elon Musk tweeted about it.

And in 2024, the Taproot Wizards team released the "Quantum Cats" collection of Bitcoin-based NFTs. Interestingly, these cat images evolve over time (although their evolutionary path is encrypted and not apparent until unlocked). The "genesis" image of the collection, "Genesis Cat," sold at a Sotheby's auction for the equivalent of 254 million USD!

What is the controversy with Bitcoin NFTs?

The advent of the Ordinals protocol has incited a significant discussion among the Bitcoin community, prompting essential inquiries. Should Bitcoin's role be confined to a monetary function, or should it broaden its scope to encompass additional applications? Is the Ordinals protocol encroaching on the Bitcoin network?

The Bitcoin blockchain, due to its restricted block size and network structure, has traditionally facilitated only payment transactions. This architecture encourages the development of solutions on top of the blockchain, adding layers to enhance the network's programmability and scalability.

1. Diverging use case for Bitcoin

The recent surge in Ordinals has drawn attention and scrutiny from the Bitcoin community. There are concerns that it could divert from Bitcoin's fundamental purpose as a medium of exchange and whether Ordinals are an efficient use of block space. Ordinals, which can take the form of images, audio clips, or even games, necessitate space that detracts from financial data, potentially causing a significant slowdown in on-chain confirmation times and increased transaction fees.

Some passionate members of the Bitcoin community are upset over this development and are strongly opposed to NFTs hosted on the Bitcoin blockchain. The Bitcoin community is generally very conservative and tends to favor stability and network reliability. They make relatively infrequent code updates and tend to ignore calls to make the network as fast or as feature-rich as rival cryptocurrencies.

2. Challenge to Bitcoin's Fungibility

Ordinals also pose a challenge to Bitcoin's fungibility, a core characteristic of money. Ordinal inscriptions are embedded into a single satoshi, conferring a degree of rarity to it, much like how numismatic coins are unique physical items collected for their rarity.

Ordinal satoshis assume distinct identities that can be monitored, transferred, and imbued with valuable information, such as text or an image. This process makes the satoshi unique, effectively transforming it into a non-fungible token (NFT). Contrarily, the conventional viewpoint maintains that all satoshis should be treated as equal to preserve an essential attribute of money.

3. The permissionless nature of the Bitcoin blockchain means that it is impossible to prevent people from storing illegal or malicious data on the blockchain -- permanently.

How do you use an Ordinals wallet to back up and protect Bitcoin NFTs?

The Ordinals wallet is very straightforward to use, and the other Taproot-capable wallets are similar:

  • Create an account, secure your seed backup, and deposit funds into the wallet.
  • Be careful with the type of Bitcoin public addresses, use a Taproot-enabled address (usually starts with bc1p prefix).
  • Use that address to receive the Bitcoin NFT from the marketplace or trading platform you've chosen for Bitcoin NFT purchases.
Back up the recovery phrase for your Ordinals wallet as you would for any other wallet.

How do you ensure inheritance of Bitcoin NFTs?

As Bitcoin Ordinals become an even more prominent part of the Web3 world, obviously you have to care about inheritance of Bitcoin NFTs in the same way as any other Web3 digital asset. Web3 asset inheritance is different from the relatively straightforward steps for a traditional inheritance, where you go to the bank or the broker, you tell them that someone has passed on or is incapacitated, and you are given access to those assets. In contrast, with Web3 assets, you, the owner, are responsible for the security and safekeeping of those assets. If you haven't recorded all details about your assets and communicated them to the people who are going to be the beneficiaries, your assets will likely be lost. Even if you did record the details correctly, there are still a lot of ways for heirs to go wrong with complex technical things during the succession process.

...unless you set up Crypto Inheritance Management today.

It's simple—if you don't worry about it, nobody else will—not your software or hardware wallets vendors, not your exchanges, not your wealth managers. So you have to think about how to protect the generational wealth you have created and reduce the risks around passing that wealth on to your family and heirs. What are the challenges with crypto inheritance?

  • Crypto Wallets are difficult to use and do not offer crypto inheritance management. In fact, most of them tell you to write down your seed phrase on a piece of paper which is practically useless.
  • Some people back up their wallet seed phrases or private keys on paper, local devices like hardware wallets or USBs, or in the cloud - all of these options have severe drawbacks from hacking, to accidental loss, to loss of cloud services. No one wants that to happen to their crypto generational wealth.
  • Software wallets operate on specific blockchains, yet your crypto assets span multiple blockchains, for inheritance to work, you must be able to manage inheritance across every blockchain - now and forever.
