The Ordinals protocol has introduced many to the world of digital collectibles—or as the protocol’s creator, Casey Rodarmor, calls them, "digital artifacts." By allowing custom data to be inscribed directly onto individual satoshis (the smallest unit of Bitcoin), Ordinals opened the door to a new form of value and expression on the Bitcoin blockchain.
Among these, rare satoshis—or rare sats—have gained popularity as unique collectibles that mark significant moments in Bitcoin’s history. In this article, we explore what rare sats are, how they are categorized, and how you can identify and verify their rarity.
Understanding Satoshis
Before diving into rare sats, it’s essential to understand what a satoshi is. A satoshi represents the smallest denomination of Bitcoin, equivalent to one hundred millionth of a BTC. Named after Bitcoin’s pseudonymous creator, Satoshi Nakamoto, this tiny unit enables microtransactions and reflects the decentralized and innovative ethos of Bitcoin.
For example, just as cents make dollar transactions more manageable, satoshis allow precise and accessible pricing in the Bitcoin economy. Every satoshi transaction is recorded on the blockchain, ensuring transparency and security—even for the smallest amounts.
The Origin of Rare Sats
Rare sats emerged from the Ordinals protocol, launched by Casey Rodarmor in January 2023. This protocol uses existing Bitcoin upgrades like Taproot and SegWit to inscribe data—such as images, text, or code—onto individual satoshis. Each satoshi is assigned a unique ordinal number based on its creation order, making it possible to track and identify specific units.
This innovation turned satoshis into more than just currency; they became digital artifacts whose value could be derived from rarity, historical significance, or inscribed content.
Categories of Rare Sats
Rare sats are classified based on their scarcity and historical context. Here are the main categories:
Common Sats
These are the majority of satoshis and hold no distinctive traits beyond their transactional use.
Uncommon Sats
The first satoshi mined in each new block falls into this category. These are slightly rarer than common sats.
Rare Sats
These are the first satoshis mined after each Bitcoin difficulty adjustment, which occurs approximately every two weeks. Their scarcity stems from the periodic nature of these adjustments.
Epic Sats
Epic sats are the first satoshis created after a Bitcoin halving event, which happens every four years. These are highly sought after due to their infrequency.
Legendary Sats
These are exceptionally rare, minted after coinciding major events—such as a halving and a difficulty adjustment occurring simultaneously.
Mythic Sats
The rarest of all, mythic sats refer to the very first satoshis mined by Satoshi Nakamoto. Only one exists, making it the ultimate digital artifact.
Exotic Sats
Beyond the primary categories, exotic sats include subtypes like:
- Black Sats: The last satoshi in a block that concludes a significant event.
- Pizza Sats: Satoshis from the infamous 2010 transaction where 10,000 BTC were used to buy two pizzas. These are historically symbolic and celebrated annually on Bitcoin Pizza Day.
The Rodarmor Rarity Index offers a systematic way to classify and evaluate these sats based on their unique attributes.
What Drives the Value of Rare Sats?
Not all satoshis are created equal. Some are valued highly due to:
- Historical Significance: Sats linked to iconic events, like the first pizza transaction, carry cultural and historical weight.
- Position in Block: The first or last satoshi in a block is often more valuable due to its symbolic placement.
- Ordinal Inscriptions: Sats with unique inscribed content—art, text, or code—can become one-of-a-kind collectibles.
- Market Dynamics: Supply, demand, and trends within the crypto community influence prices.
- Technological Milestones: Sats associated with major Bitcoin upgrades (e.g., SegWit or Taproot) are prized for their technological significance.
How to Identify and Verify Rare Sats
Several tools and platforms can help you verify the authenticity and rarity of a satoshi:
Ordscan
This tool provides detailed information about a satoshi’s ordinal number, inscription data, and mining context. It’s useful for browsing and validating rare categories.
Blockchain Explorers
Platforms like Blockstream and BTC.com allow you to trace a satoshi’s transaction history and verify its block details—essential for confirming rarity.
NFT Marketplaces
Marketplaces that support Bitcoin-based NFTs, such as Gamma.io, often include rarity rankings and market data to help assess value.
Community Engagement
Forums like BitcoinTalk and dedicated Discord channels are rich sources of collective knowledge and real-time discussions about rare sats.
Social Media and Blogs
Developers and influencers frequently share insights on platforms like X (formerly Twitter) and Medium, offering updates and discoveries related to rare satoshis.

The Future of Rare Sats
Casey Rodarmor has proposed "light pools"—a decentralized trading system that uses a node network to facilitate efficient, low-cost trading of Bitcoin-based assets like rare sats. By leveraging Bitcoin’s UTXO model and digital signatures, light pools could offer a scalable and secure marketplace without compromising decentralization.
This innovation may further boost the liquidity and accessibility of rare sats, creating new opportunities for collectors and traders.
Conclusion
Satoshis are not just units of currency—they are evolving into historical artifacts and unique digital collectibles. Thanks to the Ordinals protocol, rare sats now represent memorable moments, technological milestones, and cultural touchstones within the Bitcoin ecosystem.
As the market for these digital artifacts grows, understanding how to identify, verify, and value them becomes increasingly important for enthusiasts and collectors alike.
