Ordinals Technical Overview
Ordinals bring a new layer of functionality to Bitcoin, introducing features that set it apart from other digital asset systems.
Bitcoin Updates That Power Ordinals
Ordinals leverage Bitcoin’s OP_RETURN function to inscribe data directly onto individual satoshis. This method creates a permanent record on Bitcoin’s blockchain without disrupting its existing infrastructure [10]. By doing so, specific satoshis can be marked with unique data, all while staying compatible with Bitcoin’s core operations.
Here’s what these updates enable:
- The ability to store data in a way that mimics smart contracts, without modifying Bitcoin’s fundamental design.
- The use of OP_RETURN to assign permanent data to satoshis within Bitcoin’s current framework.
Ordinals vs. Traditional NFTs
The differences between ordinals and NFTs are rooted in their technical design:
| Feature | Ordinals | Traditional NFTs |
|---|---|---|
| Data Storage | Fully on-chain | Often off-chain with blockchain links |
| Smart Contracts | Not required | Relies on smart contracts |
| Blockchain | Native to Bitcoin | Typically on Ethereum or others |
| Royalty Structure | No built-in royalties | Supports programmable royalties |
| Creation Process | Requires technical tools | Simplified platforms available |
One standout feature of ordinals is their approach to data permanence. Unlike most NFTs, which store metadata off-chain and use blockchain references, ordinals inscribe all data directly onto Bitcoin’s blockchain. This ensures long-term durability but comes at the cost of reduced transaction throughput [2]. This trade-off influences how Bitcoin handles operations [6].
This unique structure also opens up opportunities for ordinals in decentralized finance (DeFi). By integrating directly with Bitcoin, ordinals could serve as foundational elements for decentralized trading systems. This showcases Bitcoin’s ability to support new use cases while sticking to its core principles of decentralization and security.
Getting Started with Ordinals
Ordinals build on Bitcoin’s DeFi capabilities, offering unique digital assets on the Bitcoin blockchain. Let’s break down what you need to know to start working with them.
How to Create Ordinals
Creating ordinals requires some technical know-how and specific tools. To get started, you’ll need to set up and run a Bitcoin full node, which means having more than 500GB of storage space[9], a reliable internet connection, and familiarity with command-line tools.
Here’s the basic setup required:
- A fully synced Bitcoin Core node with the ord client
- A wallet that supports Taproot
- Some BTC to cover network fees
If running a full node feels too complex, platforms like Gamma.io and Ordinalsbot simplify the process. They offer user-friendly options for creating inscriptions without the need for a full node. However, keep in mind that using these services involves placing some trust in them[11].
Common Uses for Ordinals
Although ordinals gained popularity through digital art, their applications go far beyond that. They enhance Bitcoin’s role in decentralized trading systems and other areas. Here are some key use cases:
| Use Case | Description | Key Advantage |
|---|---|---|
| BRC-20 Tokens | Create fungible tokens | Works directly on Bitcoin |
| Document Timestamping | Record proof of existence | Tamper-proof verification |
| Digital Identity | Store credentials | Decentralized authentication |
| DEX Listings | Represent trading pairs | Immutable ownership |
While setting up ordinals requires technical effort, the costs are relatively low. Standard inscriptions typically cost between $2 and $20[11]. For valuable collections, consider using hardware wallets or multisignature setups for added security[9].
For developers, tools like Hiro Ordinals provide APIs and resources to integrate ordinals into applications seamlessly[8].

Effects on Bitcoin Operations
Ordinals have introduced changes that are reshaping Bitcoin’s network economics and infrastructure, altering how the system operates at its core.
Mining Economics and Fees
The introduction of ordinals has changed how fees work within the Bitcoin network. Miner revenues now hinge on balancing profits from inscriptions with the utility of decentralized trading. This adjustment in fee structures is altering revenue streams and creating new financial incentives for those involved in maintaining the network.
Network Storage Concerns
Ordinals have caused Bitcoin’s blockchain to grow at a much faster rate – jumping from an annual growth of around 50GB to over twice that amount [2]. In just six months after ordinals were introduced, the blockchain expanded from 25GB to 60GB [5]. This rapid growth is a direct result of ordinals’ method of storing all data directly on-chain. The increased demand for block space has pushed many blocks to consistently reach the 4MB size limit [10].
Some of the key effects include:
- Higher storage demands for node operators, who need to maintain full copies of the blockchain
- More frequent network congestion during periods of heavy inscription activity
These issues have sparked debates about potential scaling solutions, such as using Taproot-enhanced pruning techniques [4] or adopting Layer 2 systems to handle some of the inscription load [6].
"Faster blockchain growth risks centralization as node operation costs rise [5]"
Ordinals in DeFi Systems
DeFi systems are now utilizing ordinals’ integration with Bitcoin, transforming how digital assets are traded on the Bitcoin network. Protocols like Ordex use PSBTs (Partially Signed Bitcoin Transactions) for trustless, direct on-chain trading [1]. Meanwhile, DEFX has introduced ordinal trading features, including perpetual futures contracts with leverage options [11].
Trading ordinals on decentralized exchanges (DEXs) comes with distinct features compared to traditional NFT platforms:
| Feature | Key Characteristic |
|---|---|
| Settlement | Direct on-chain transactions that prioritize security |
| Trading Pairs | Bitcoin and dollar-pegged assets |
| Transaction Costs | Higher fees, which can impact trading strategies [3] |
| Market Making | Single-sided liquidity pools offering opportunities for providers [7] |
"The lack of smart contract functionality on Bitcoin necessitates more complex trading mechanisms, which can be both a challenge in terms of implementation and a benefit in terms of security" [8].
DeFi Development Trends
By January 2024, protocols based on ordinals had reached a total value locked (TVL) of $100 million [2]. Cross-chain applications are expanding their utility by using bridge protocols, enabling ordinal holders to tap into broader DeFi services while staying connected to Bitcoin [4].
Here are some key advancements:
- Lending Protocols: Platforms now allow users to borrow against BRC-20 tokens and inscriptions, improving how efficiently capital is used [12].
- Yield Generation: Ordinal staking in liquidity pools is becoming popular, with rewards paid in Bitcoin [7].
- Governance Systems: Ordinal-based voting mechanisms are being developed to strengthen governance security [10].
These advancements leverage Bitcoin’s Taproot features (as discussed in the Technical Overview), ensuring secure on-chain settlements and true ownership. However, they also come with increased transaction fees, as noted earlier.
Looking Ahead: Ordinals Development
Network Scaling Solutions
To tackle Bitcoin’s storage challenges, developers are exploring three main strategies to keep the network running smoothly:
| Solution | Benefit |
|---|---|
| Optimized Inscription | Reduces data payloads by 30% |
| Taproot Anchoring | Links metadata permanently |
| Bitstream Compression | Boosts storage efficiency by 4x |
With Bitcoin blocks reaching up to 4MB due to ordinal data [1], data compression methods like Schnorr signature batch processing are being tested. These approaches aim to enhance storage while keeping Bitcoin’s decentralized model intact.
Legal and Compliance Status
As ordinals become more integrated into DeFi systems, they are drawing increasing attention from regulators. Key areas of concern include:
- Copyright issues related to inscribed content
- Tax responsibilities for creators and traders
- Compliance with anti-money laundering (AML) laws
- Rules for cross-border transactions
Many ordinal marketplaces are tightening verification processes to meet these demands. To address these challenges, developers are introducing tools that align with compliance while preserving decentralization. These tools include:
- Automated copyright checks: Systems that flag potential intellectual property issues before inscriptions are finalized
- Advanced KYC integration: Similar to requirements seen on platforms like Gamma.io
- Global transaction standards: Frameworks for handling cross-border trades
The goal remains clear: balance the growth of ordinals with regulatory expectations. Developers and platforms are working together to ensure the technology stays accessible and decentralized while meeting legal standards.
