Bitcoin, the world’s first and most secure blockchain, has long been praised for its decentralization and immutability. However, unlike Ethereum or Solana, it doesn’t natively support smart contracts. Despite this limitation, innovative protocols have emerged to expand Bitcoin’s utility—introducing NFTs and fungible tokens to its ecosystem. Among the latest breakthroughs is Bitcoin Runes, a protocol redefining how fungible tokens operate on Bitcoin.
In this guide, we’ll explore what Bitcoin Runes are, how they differ from other token standards like Ordinals, Stamps, and BRC-20, and why they represent a major leap forward in scalability and efficiency for the Bitcoin network.
Understanding Bitcoin’s Token Ecosystem
Before diving into Runes, it’s essential to understand the existing frameworks that enabled digital assets on Bitcoin:
Bitcoin Ordinals
Ordinals revolutionized Bitcoin by allowing users to inscribe unique data—such as images, text, or code—onto individual satoshis (the smallest unit of BTC). Each inscribed satoshi becomes a distinct digital artifact, effectively creating NFTs on Bitcoin. These "inscriptions" are stored directly on-chain and can be transferred just like regular Bitcoin.
Bitcoin Stamps (SRC-20)
An alternative to Ordinals, Stamps store digital art within transaction outputs rather than individual satoshis. This method ensures data permanence and resists pruning but comes with higher fees and stricter size limitations.
BRC-20 Tokens
Inspired by Ethereum’s ERC-20 standard, BRC-20 uses JSON files embedded via Ordinals to issue fungible tokens on Bitcoin. While groundbreaking, BRC-20 has a critical flaw: it generates excessive Unspent Transaction Outputs (UTXOs), contributing to network bloat and congestion.

What Are Bitcoin Runes?
Bitcoin Runes is a new protocol designed to create and manage fungible tokens on the Bitcoin blockchain more efficiently than BRC-20. Created by Casey Rodarmor—the same developer behind Ordinals—Runes aims to solve the UTXO bloat problem while maintaining full compatibility with Bitcoin’s base layer.
Instead of relying on off-chain metadata or complex inscription methods, Runes uses a streamlined approach based on standard Bitcoin transactions. It introduces a unified output model, where token creation, minting, and transfers occur without generating unnecessary UTXOs.
This means:
- Lower transaction fees
- Reduced blockchain clutter
- Improved scalability for tokenized assets
Runes operate through a system of “etching” (creating a token), “minting” (issuing new supply), and “transferring” (sending tokens), all encoded directly into transaction OP_RETURN fields—a native Bitcoin feature used for storing small amounts of metadata.
How Runes Improve Upon BRC-20
While BRC-20 opened the door for fungible tokens on Bitcoin, its design leads to significant inefficiencies:
| Issue | BRC-20 | Bitcoin Runes |
|---|---|---|
| UTXO Generation | High – each transfer creates new UTXOs | Minimal – uses consolidated outputs |
| On-chain Footprint | Large due to JSON inscriptions | Compact using OP_RETURN encoding |
| Transfer Efficiency | Requires multiple steps | Streamlined process |
| Network Impact | Contributes to congestion | Reduces strain on the blockchain |
By minimizing UTXO expansion, Runes make it feasible to scale token operations on Bitcoin without compromising security or decentralization.
Moreover, Runes are Lightning Network-compatible, enabling fast, low-cost microtransactions. This opens doors for real-world use cases such as:
- Micropayments for content creators
- Loyalty points and rewards systems
- Stablecoins issued on Bitcoin
Where to Trade Bitcoin Runes
As adoption grows, several platforms now support the trading and management of Runes:
- Magic Eden: One of the first marketplaces to integrate Runes trading, offering a seamless experience for buying and selling.
- Cube: A dedicated BTC layer-focused platform with robust tools for interacting with Runes and other Bitcoin-based assets.
Wallet support is still evolving. While Phantom Wallet currently does not fully support Runes, it remains a top choice for managing native BTC, Ordinals, and BRC-20 tokens across multiple chains. It offers browser extensions (Chrome, Firefox, Brave, Edge) and mobile apps (iOS, Android), along with built-in fiat on-ramps via partners like MoonPay and PayPal.
For cross-chain users, Phantom’s Cross-Chain Swapper allows easy bridging between Ethereum, Solana, and Polygon—ideal for those diversifying their crypto portfolios.

Frequently Asked Questions (FAQ)
What is the main advantage of Bitcoin Runes over BRC-20?
The primary benefit is efficiency. Runes drastically reduce UTXO bloat by using a consolidated output model, resulting in lower fees, less network congestion, and better long-term scalability compared to BRC-20.
Can I store Bitcoin Runes in any wallet?
Not all wallets support Runes yet. You’ll need a wallet that specifically integrates with the Runes protocol. Popular options include Runes-native wallets or updated versions of multi-chain wallets as they roll out support.
Are Bitcoin Runes NFTs?
No. Bitcoin Runes are designed exclusively for fungible tokens, meaning each unit is interchangeable with another of the same type. For non-fungible assets on Bitcoin, protocols like Ordinals or Stamps are used instead.
How do I create a Rune?
Creating a Rune involves “etching” a new token on the Bitcoin blockchain using specific transaction formats that define properties like symbol, supply, and minting rules. Tools and interfaces are emerging to simplify this process for developers and creators.
Is the Runes protocol secure?
Yes. Runes rely entirely on Bitcoin’s base layer and use standardized scripting (OP_RETURN), meaning they inherit Bitcoin’s robust security model without introducing smart contract risks.
Does Runes compete with Ordinals or BRC-20?
Not exactly. While there’s overlap in functionality, Runes complement existing protocols by solving specific inefficiencies in fungible token issuance. Think of them as an optimized upgrade path rather than a replacement.
The Future of Fungible Tokens on Bitcoin
Bitcoin Runes represent a pivotal moment in the evolution of Bitcoin’s ecosystem. By addressing the core limitations of earlier token standards, Runes pave the way for sustainable growth in decentralized finance (DeFi), digital ownership, and peer-to-peer value exchange—all without altering Bitcoin’s foundational principles.
As developer tooling improves and wallet integrations expand, expect broader adoption across exchanges, marketplaces, and everyday payment systems. With Lightning Network compatibility, Runes could even become the backbone of a new generation of instant, low-cost digital transactions powered by Bitcoin.
Whether you're an investor, developer, or enthusiast, now is the time to understand how Runes, Ordinals, and other innovations are unlocking new possibilities on the world’s most trusted blockchain.
