The Bankless Guide to Ordinals

·

Bitcoin continues to evolve beyond its original purpose as a peer-to-peer electronic cash system. With the emergence of Ordinals, the network has unlocked new capabilities for digital ownership, onchain data storage, and collectible creation—ushering in a renaissance for Bitcoin-based innovation. This guide dives deep into how Ordinals work, their impact on the NFT landscape, and what they mean for the future of Bitcoin.

Understanding Bitcoin Ordinals

At its core, Bitcoin Ordinals is a protocol that allows users to inscribe data—such as text, images, SVGs, or even HTML—onto individual satoshis, the smallest units of Bitcoin (one hundred millionth of a BTC). These inscribed satoshis become unique digital artifacts, often referred to as "Bitcoin NFTs" or "Ordinals."

The inscription process embeds data directly into the witness section of a Bitcoin transaction—a part traditionally used for signature verification. Once confirmed and mined, the data becomes permanently etched onto the blockchain. Unlike many Ethereum-based NFTs that rely on offchain storage (like IPFS), Ordinals are fully onchain, ensuring maximum immutability and decentralization.

Inscriptions are finally ready for Bitcoin mainnet.
Inscriptions are like NFTs, but are true digital artifacts: decentralized, immutable, always on-chain, and native to Bitcoin.

This permanence means each inscribed satoshi carries its data forever, making it distinguishable from all others. Thanks to Ordinal theory, these satoshis can be tracked across transactions, enabling ownership transfer through standard Bitcoin mechanics—though careful "sat control" is required to ensure the correct satoshi moves during transactions.

Why Onchain Storage Matters

One of the most compelling advantages of Ordinals is their fully onchain nature. While platforms like Ethereum often store NFT metadata offchain due to cost and scalability constraints, Ordinals leverage Bitcoin’s robust security model to keep everything—art, metadata, and ownership history—permanently recorded.

Although Bitcoin lacks advanced smart contract functionality compared to other blockchains, Ordinals make up for it with an unmatched permanence-to-cost ratio. With lower storage costs than Ethereum’s onchain NFTs and no reliance on external servers or decentralized file systems, Ordinals offer a more resilient form of digital ownership.

This shift challenges traditional assumptions about what Bitcoin can do. Far from being just a store of value or payment rail, Bitcoin now supports rich, user-generated content directly on its base layer.

BRC-20 Tokens: Fungibility Meets Inscriptions

Building atop the Ordinals protocol, BRC-20 tokens have emerged as an experimental fungible token standard. Unlike ERC-20 tokens on Ethereum, BRC-20s aren’t powered by smart contracts. Instead, they’re created by inscribing JSON data into a Bitcoin transaction.

This JSON defines key token properties such as:

Transfers and balance tracking occur through additional inscriptions that record batched movements—e.g., sending 100 or 500 tokens at once. While not fully fungible in practice (due to inscription uniqueness), BRC-20s have gained massive traction.

Notably, $ORDI became the first BRC-20 token to surpass a **$1 billion market cap**, signaling strong community interest and speculative momentum. Despite their unofficial status and technical limitations, BRC-20s represent a novel use case for Bitcoin: launching community-driven meme coins and utility tokens without complex infrastructure.

Rare Sats and the Art of Sat Hunting

A fascinating byproduct of the Ordinals protocol is the rise of Rare Sats—satoshis deemed special based on their position in Bitcoin’s mining history. The Rodarmor Rarity Index, named after Ordinals creator Casey Rodarmor, classifies satoshis into tiers:

The rarest of all is the very first satoshi ever mined—the "Genesis Sat"—which holds mythic status. Other notable categories include:

This classification has given birth to "Sat Hunting"—the practice of searching for and collecting rare satoshis. Enthusiasts use specialized tools to track these digital artifacts, turning otherwise identical units into prized collectibles.

Marketplaces and Wallets for Ordinals

To interact with Ordinals and BRC-20 tokens, you need a wallet that supports inscribed satoshis and can manage both NFTs and fungible tokens on Bitcoin.

Popular wallets include:

Once set up, users can explore leading marketplaces such as:

These platforms allow buying, selling, and discovering new inscriptions—from digital art to experimental tokens.

Adoption and Community Response

Since their launch in early 2023, Ordinals have sparked intense debate within the Bitcoin community.

Traditionalists argue that using Bitcoin for NFTs and data storage goes against its original vision—viewing such activity as bloat or spam. Some liken it to earlier criticisms of Counterparty NFTs in 2014, where similar concerns were raised about blockchain misuse.

However, a growing cohort sees Ordinals as a natural evolution. By increasing transaction volume, Ordinals boost miner revenue through fees—a critical development as Bitcoin’s block subsidy diminishes over time due to halvings. This shift could help sustain network security in a post-subsidy era.

Moreover, Ordinals have attracted artists, creators, and developers back to Bitcoin, revitalizing interest in its base layer. The surge in activity has also prompted discussions around scalability, layer-2 solutions, and future upgrades like Taproot Assets.

Challenges and Future Outlook

Despite their promise, Ordinals face real challenges:

Still, the trend points toward broader adoption. As infrastructure improves and more users recognize the cultural and financial value of onchain artifacts, Ordinals may become a cornerstone of Bitcoin’s next phase.

The conversation around whether Bitcoin should support NFTs isn’t just technical—it’s philosophical. But one thing is clear: Ordinals have expanded what’s possible on Bitcoin, blending scarcity, history, and creativity in unprecedented ways.

Frequently Asked Questions (FAQ)

What is an Ordinal?
An Ordinal is a protocol that assigns unique identities to individual satoshis, allowing them to carry inscribed data like images or text directly on the Bitcoin blockchain.

How are Ordinals different from Ethereum NFTs?
Ordinals are fully onchain with no reliance on external storage. They don’t require smart contracts and are natively integrated into Bitcoin transactions.

Can I buy or sell Ordinals?
Yes. You can trade Ordinals on dedicated marketplaces like OKX, Magic Eden, and Gamma using compatible wallets such as Xverse or Leather.

What are BRC-20 tokens?
BRC-20s are fungible tokens created via JSON inscriptions on Bitcoin. They’re experimental and not based on smart contracts but have gained popularity through community-driven launches.

What does “Sat Hunting” mean?
Sat Hunting involves tracking down rare satoshis based on their mining order or historical significance using tools that analyze the Rodarmor Rarity Index.

Do Ordinals affect Bitcoin’s performance?
Yes. High inscription activity increases block space usage, leading to temporary congestion and higher fees—sparking ongoing debates about scalability and network priorities.
