The Runes protocol represents a significant step forward in the evolution of the Bitcoin network. It is a new fungible token standard that enables the creation and management of interchangeable tokens directly on the Bitcoin blockchain. Developed by Casey Rodarmor, the same innovator behind the groundbreaking Ordinals protocol, Runes aims to provide a more efficient and integrated token system compared to earlier standards.
By leveraging Bitcoin's existing Unspent Transaction Output (UTXO) model, Runes minimizes unnecessary data storage, leading to a more streamlined and resource-efficient approach to tokenization. This article explores everything you need to know about the Runes protocol, how it functions, and its role in the broader Bitcoin ecosystem.
Understanding the Runes Protocol
The Runes protocol is fundamentally a set of rules that allows for the issuance of fungible tokens on Bitcoin. A fungible token is one where each unit is identical and interchangeable, much like Bitcoin itself or traditional currencies. This contrasts with non-fungible tokens (NFTs), which are unique digital assets.
Runes operates by embedding specific data into Bitcoin transactions, a process known as "etching." This data defines the token’s core properties, such as its name, symbol, and total supply. This method utilizes the OP_RETURN field, a part of Bitcoin's scripting language that allows for a small amount of arbitrary data to be included in a transaction.
The Need for Runes on Bitcoin
Bitcoin's primary design is as a decentralized peer-to-peer electronic cash system. Its architecture intentionally lacks native support for complex smart contracts, which has historically limited its functionality for creating diverse digital assets. Previous attempts to introduce tokenization, such as the BRC-20 standard, often led to network inefficiencies, including excessive data storage and congestion.
The Runes protocol was created to overcome these challenges. It provides a native and efficient way to create tokens without overburdening the network. This expansion of utility opens doors to new applications on Bitcoin, including aspects of decentralized finance (DeFi), gaming assets, and community tokens, all while adhering to Bitcoin's core principles of security and decentralization.
How the Runes Protocol Operates
The functionality of Runes is elegantly simple and built upon Bitcoin's existing infrastructure. The process revolves around the UTXO model, which is a fundamental building block of how Bitcoin tracks ownership.
When a token is created, or "etched," its defining information is inscribed into an OP_RETURN output within a Bitcoin transaction. Subsequent transactions that transfer these tokens simply reference this original data. This approach is highly efficient because it avoids creating excessive "junk" UTXOs—a common problem with other token standards that clogged the network.
This efficient design means that creating and transferring Runes tokens has a minimal impact on the overall blockchain, preserving storage space and keeping transaction fees lower for everyone.
A Step-by-Step Guide to Creating a Rune
For those interested in creating their own token, the process is relatively straightforward. Here’s a general breakdown of the steps involved:
- Define Token Parameters: The first step is to determine the core attributes of your token. This includes its name, ticker symbol, divisibility, and the total supply that will ever exist.
- Prepare a Bitcoin Transaction: Using a compatible wallet, you will construct a transaction. This transaction includes an
OP_RETURNoutput containing the encoded data that defines your new token according to the Runes protocol specifications. - Broadcast the Transaction: The completed transaction is then broadcast to the Bitcoin network. Miners will verify the transaction and include it in a block, at which point the token's existence is officially recorded on the blockchain.
- Token Distribution: The initial allocation of tokens, as defined in the etching process, is distributed to the specified Bitcoin addresses once the transaction is confirmed.

Runes vs. Ordinals: Key Differences
While both protocols were created by Casey Rodarmor and exist on Bitcoin, they serve entirely different purposes and should not be confused.
Ordinals is a protocol for creating non-fungible tokens (NFTs). It involves inscribing unique data—such as images, text, or video—onto individual satoshis (the smallest unit of Bitcoin), turning them into distinct digital artifacts or collectibles.
Runes, on the other hand, is exclusively for fungible tokens. Each unit of a specific Rune is identical and holds the same value. Technologically, Runes is considered more efficient as it uses the OP_RETURN method and is built for the UTXO model, reducing its environmental footprint on the network compared to the data-intensive nature of some Ordinals inscriptions.
In short, Ordinals are for unique digital items, and Runes are for interchangeable tokens.
Notable Projects Using the Runes Protocol
The ecosystem around Runes has grown rapidly, with several projects capturing significant attention and demonstrating the protocol's versatility. Some of the most notable early examples include:
- UNCOMMON•GOODS (GOODS): The first Rune, hard-coded by Casey Rodarmor himself. It features a minting process that is scheduled to conclude around the time of the next Bitcoin halving, adding scarcity.
- SATOSHI•NAKAMOTO (SATOSHI): A tribute token that quickly achieved one of the highest market capitalizations in the early days of the protocol's launch.
- DOG•GO•TO•THE•MOON (DOG): A popular memecoin project that rewarded its early community by airdropping tokens to holders of specific Bitcoin Ordinals collections.
- Z•Z•Z•Z•Z•FEHU•Z•Z•Z•Z•Z (ᚠ): Inspired by the oldest runic alphabet, this project was among the first to be launched after the protocol went live.
These projects highlight the range of possibilities, from artistic endeavors and cultural tributes to community-driven memecoins, all built natively on Bitcoin.
How to Acquire Runes Tokens
Interested in purchasing Runes? These tokens are available on several specialized marketplaces. Since they are built directly on Bitcoin, their availability is primarily on platforms that support Bitcoin-based assets.
Step 1: Choose a Compatible Wallet
Your first step is to set up a Bitcoin wallet that supports the Runes protocol. Not all standard Bitcoin wallets can display or manage Runes tokens. Recommended options include Xverse, Leather, or Ordinals Wallet.
Step 2: Fund Your Wallet with BTC
Runes transactions require Bitcoin (BTC) to pay for both the token itself and the network transaction fees. Transfer enough BTC from your exchange or another wallet to your new Runes-compatible wallet.
Step 3: Connect to a Marketplace
Visit a marketplace that supports Runes trading. Connect your wallet to the platform securely.
Step 4: Browse and Select a Rune
Explore the available collections. Pay close attention to the project's details, community, and transaction history to ensure you are making an informed decision.
Step 5: Complete Your Purchase
Once you’ve selected a token, confirm the transaction. The purchase will be processed on the Bitcoin network, and your new Runes token will appear in your connected wallet after the transaction is confirmed.

Storing Your Runes Securely
Can you store Runes in a regular Bitcoin wallet? The answer is nuanced. While the underlying transaction is on the Bitcoin blockchain, standard wallets may not recognize or be able to interact with the Runes token data embedded within.
For full functionality—including sending, receiving, and viewing your token balance—you must use a wallet that has integrated support for the Runes protocol. The following wallets are known to offer compatibility:
- Xverse Wallet: A popular Bitcoin wallet that was one of the first to add native support for Runes.
- Leather Wallet: Previously known as Hiro Wallet, it provides robust support for both Ordinals and Runes.
- Ordinals Wallet: As the name implies, this wallet is specifically designed for managing Bitcoin-based digital assets like Ordinals and Runes.
The Future of Runes on Bitcoin
The Runes protocol successfully expands the utility of the Bitcoin network by enabling efficient fungible token creation. Its key innovation lies in its use of Bitcoin's native UTXO model, which promotes better scalability and reduces unnecessary blockchain congestion compared to its predecessors.
The long-term success and adoption of Runes will likely be intertwined with the overall health and growth of the Bitcoin ecosystem. As more developers and creators build on this standard, it has the potential to unlock new and innovative use cases for the world's oldest blockchain.
