Bitcoin has long been seen as the original and most secure blockchain, primarily used for peer-to-peer transactions and value storage. But with the emergence of Bitcoin Ordinals, the network is undergoing a cultural and technological evolution—ushering in a new era of digital ownership directly on Bitcoin.
What Are Bitcoin Ordinals?
At their core, Ordinals are unique digital assets inscribed directly onto individual satoshis—the smallest unit of Bitcoin (1 satoshi = 0.00000001 BTC). Unlike traditional NFTs that rely on sidechains or smart contract platforms like Ethereum, Ordinals exist natively on the Bitcoin blockchain. This makes them fully decentralized, immutable, and as secure as Bitcoin itself.
The innovation became possible thanks to Bitcoin’s Taproot upgrade in 2021, which improved transaction efficiency and privacy. In January 2023, developer Casey Rodarmor introduced the Ordinals protocol, enabling users to inscribe data—such as images, text, or audio—directly into a satoshi. These inscribed sats become one-of-a-kind digital artifacts, verifiable and transferable using standard Bitcoin transactions.

According to the Ordinal Theory Handbook, each satoshi is assigned an ordinal number based on the order it was mined—creating a provable sequence across Bitcoin’s total supply of 21 million coins. When a satoshi is inscribed with content, it becomes a permanent part of the blockchain’s history.
While some debate whether this use aligns with Satoshi Nakamoto’s original vision, the reality is clear: Ordinals have sparked renewed interest in Bitcoin’s utility beyond payments, opening doors for digital art, collectibles, and even decentralized publishing.
How Do Ordinals Differ From Traditional NFTs?
Most NFTs—especially those on Ethereum, Solana, or Polygon—are not fully on-chain. Instead, they typically store metadata (like an image link) off-chain via systems like IPFS. This creates potential vulnerabilities: if the hosting service goes down or the link changes, the NFT may lose its visual or functional integrity.
In contrast, Bitcoin Ordinal inscriptions store all data directly on the blockchain. This means:
- No reliance on external servers
- Complete permanence and censorship resistance
- True digital scarcity rooted in Bitcoin’s security model
Because of this, many refer to Ordinals as “complete” NFTs—digital artifacts that live entirely within Bitcoin’s ledger. Additionally, while Ethereum-based NFTs often include built-in royalties for creators, Ordinals do not enforce this by default. However, marketplaces like Gamma have introduced opt-in creator earnings, giving artists control over post-sale royalties.
Understanding Ordinal Inscriptions
Every Bitcoin is divisible into 100 million satoshis. With Ordinals, each satoshi can be tracked, numbered, and inscribed with data. The inscription process leverages the witness section of a SegWit (Segregated Witness) transaction—a feature introduced in 2017 that separates signature data from transaction data, freeing up space for additional information.
Due to block size limits, inscriptions are capped at 4MB per block, roughly equivalent to a high-resolution image or short video clip. As Bitcoin undergoes periodic halvings—reducing block rewards and increasing scarcity—the rarity of individual satoshis grows, potentially enhancing the value of inscribed ones.
This limited block space has also led to increased competition for transaction inclusion, contributing to temporary spikes in network congestion. Yet, these challenges reflect growing demand and engagement within the ecosystem.
How to Create an Ordinal Inscription
Originally, creating an Ordinal required advanced technical skills: running a full Bitcoin node, syncing the entire blockchain (which can take days), setting up an Ordinals-compatible wallet, and manually crafting transactions.
However, new tools have democratized access. Platforms now offer no-code solutions that allow anyone with a Bitcoin address to inscribe files—whether JPEGs, PNGs, or text—with just a few clicks.

These platforms simplify the process by handling backend complexities like fee customization, batch inscriptions, and collection launches. For example, creators can now mint entire NFT collections using intuitive interfaces, similar to Ethereum’s NFT marketplaces—but with the unmatched security of Bitcoin.
Wallets like Xverse and Leather have also added native support for Ordinals, making it easy to store, view, and transfer inscribed satoshis.
Notable Ordinals Collections and Use Cases
While digital art dominates early adoption, the scope of Ordinals extends far beyond NFTs.
Iconic Projects:
- Ordinal Punks: A tribute to CryptoPunks, this collection consists of 100 hand-drawn pixel art characters minted among the first 650 inscriptions.
- Taproot Wizards: A 1,000-piece generative art series that holds the record for the largest single transaction in Bitcoin history at 4MB.
- OnChainMonkey (OCM): Originally an Ethereum project, OCM inscribed all 10,000 monkeys into a single Bitcoin transaction—one of the first full 10K mints on Bitcoin.
Beyond Art:
Ordinals are being used creatively across domains:
- Permanent Publishing: Gamma.io inscribed its press release directly onto Bitcoin, marking the world’s first blockchain-based press release.
- Digital Archives: Historians and journalists are exploring ways to preserve important documents immutably.
- Memes & Culture: With meme coins like PEPE gaining traction, cultural moments are increasingly being immortalized via inscriptions.
With over 3 million inscriptions recorded to date and growing daily, the ecosystem continues to expand rapidly.
Frequently Asked Questions (FAQ)
Q: Can I send an inscribed satoshi like regular Bitcoin?
A: Yes. Once inscribed, the satoshi remains a valid unit of BTC and can be sent via any compatible wallet. However, special care must be taken during transactions to ensure the correct satoshi is transferred.
Q: Are Ordinals supported by all Bitcoin wallets?
A: No. Only wallets that support the Ordinals protocol—such as Xverse, Leather, or Hiro—can display and manage inscribed satoshis properly.
Q: Is there a gas fee for inscribing?
A: Instead of gas fees, you pay standard Bitcoin transaction fees based on network congestion and inscription size. Fees can vary significantly during peak usage.
Q: Can I update or edit an inscription?
A: No. Once data is inscribed on-chain, it is permanent and unchangeable—ensuring authenticity and integrity.
Q: Do Ordinals affect Bitcoin’s scalability?
A: They contribute to increased block space usage and mempool congestion at times. However, this reflects growing utility and does not compromise core network functions.
Q: How do I buy or trade Ordinals?
A: You can purchase them through dedicated marketplaces that support trustless trading of inscribed satoshis using Bitcoin.

The Future of Bitcoin-Centric Digital Assets
Bitcoin Ordinals represent more than just a trend—they signal a shift toward native digital ownership on the most secure blockchain in existence. By combining Bitcoin’s decentralization with creative expression, Ordinals unlock new possibilities for artists, developers, and collectors alike.
As infrastructure improves and user-friendly tools proliferate, we’re likely to see broader adoption across industries—from verifiable credentials to decentralized identity and beyond.
With continued innovation and community-driven development, Bitcoin may soon be known not just as digital gold—but as a foundational layer for the next generation of web3 experiences.
