The emergence of new token standards on Bitcoin has reignited interest in the network’s potential beyond simple value transfer. A recent research report by Franklin Fund Group, shared via Twitter, highlights Runes—a new fungible token protocol built natively on Bitcoin—as a pivotal evolution in the ecosystem. With the protocol launching alongside the 2024 Bitcoin halving, the report positions Runes as a more efficient and sustainable standard compared to earlier models like BRC-20. This article breaks down the key insights from the Franklin analysis, explores how Runes improves upon past limitations, and evaluates its long-term implications for Bitcoin’s growing role in decentralized finance.

The Rise of Bitcoin NFTs: Introducing Ordinals
Before understanding Runes, it's essential to examine their predecessor: Ordinals. While non-fungible tokens (NFTs) first gained popularity on Ethereum through the ERC-721 standard, Bitcoin lacked a widely adopted NFT framework for years—until developer Casey Rodarmor introduced the Ordinals protocol in December 2022.
Unlike traditional NFTs that often store metadata off-chain on centralized servers, Ordinals inscribe data directly onto individual satoshis (the smallest unit of Bitcoin). Each satoshi is assigned a unique ordinal number based on its mining order, enabling true on-chain provenance and ownership without relying on external infrastructure.
This native approach sparked rapid adoption. By April 2025, the total market value of Ordinals-based assets had surged to approximately $2 billion, demonstrating strong demand for digital collectibles and artifacts on Bitcoin. This growth prompted developers to ask a critical question: If Bitcoin can support NFTs efficiently, why not fungible tokens too?
Runes: A Native Fungible Token Standard for Bitcoin
Enter Runes, also created by Casey Rodarmor, designed specifically as a streamlined, Layer-1-native solution for issuing and transferring fungible tokens on Bitcoin. Scheduled to launch simultaneously with the 2024 halving—a symbolic nod to community-driven innovation—Runes aims to address core inefficiencies found in earlier standards like BRC-20.
Why BRC-20 Falls Short
BRC-20 was an experimental token standard built atop Ordinals, borrowing concepts from Ethereum’s ERC-20 model. However, it operates using an account-based system grafted onto Bitcoin’s UTXO (Unspent Transaction Output) architecture—an architectural mismatch that leads to significant drawbacks:
- Blockchain bloat: Every mint or burn generates excessive UTXO data, contributing to chain inflation.
- Higher fees: Increased transaction volume and data size drive up costs for all users.
- Security risks: Poor infrastructure and reliance on third-party indexing services create vulnerabilities.
- Poor scalability: Not compatible with off-chain scaling solutions like the Lightning Network.
These issues limit BRC-20’s viability as a long-term standard within the Bitcoin ecosystem.
How Runes Solves These Problems
Runes takes a fundamentally different approach by embracing Bitcoin’s UTXO model rather than fighting against it. Key improvements include:
- Native UTXO integration: Tokens are managed directly through UTXOs, eliminating redundant data creation.
- No off-chain dependencies: All token logic resides on-chain, ensuring censorship resistance and decentralization.
- Lightning Network compatibility: Enables fast, low-cost microtransactions for fungible tokens.
- Efficient issuance and transfers: Reduces computational overhead and minimizes block space usage.
In essence, Runes offers a cleaner, more sustainable path forward—making it a strong contender to become Bitcoin’s de facto standard for fungible tokens.

Market Potential: Can Bitcoin Compete in Fungible Token Value?
Despite Bitcoin’s dominant market capitalization—consistently ranking as the largest cryptocurrency—its ecosystem has lagged behind others in terms of tokenized asset value. When comparing the market caps of native tokens across ecosystems:
- Ethereum hosts hundreds of billions in ERC-20 token value.
- Solana supports a rapidly growing array of SPL tokens.
- In contrast, Bitcoin’s total fungible token market remains relatively small.
However, this gap presents an opportunity. With more efficient protocols like Runes removing technical barriers, Bitcoin could see exponential growth in token issuance and usage. As decentralized finance (DeFi) applications begin to emerge on Bitcoin, having a robust, scalable fungible token standard becomes not just beneficial—but essential.
Moreover, Runes’ timing aligns with increased institutional attention. The Franklin report underscores that while current activity is speculative, the underlying infrastructure improvements signal long-term viability. If adoption grows, we may witness a shift where Bitcoin evolves from being perceived solely as “digital gold” to also serving as a platform for programmable assets.
Frequently Asked Questions (FAQ)
Q: What is the main difference between BRC-20 and Runes?
A: BRC-20 uses an account-based model grafted onto Bitcoin’s UTXO system, leading to inefficiencies and blockchain bloat. Runes, by contrast, is built natively on the UTXO model, minimizing data waste and improving scalability.
Q: Who created the Runes protocol?
A: Runes was developed by Casey Rodarmor, the same engineer behind the Ordinals protocol. He designed Runes to be a cleaner, more sustainable solution for fungible tokens on Bitcoin.
Q: Is Runes compatible with the Lightning Network?
A: Yes. One of Runes’ key advantages is its compatibility with the Lightning Network, enabling instant, low-cost transfers of fungible tokens.
Q: When did Runes launch?
A: Runes launched on April 20, 2024—the same day as the Bitcoin halving—marking a symbolic milestone for the Bitcoin ecosystem.
Q: Are there investment risks associated with Runes?
A: Yes. Like all crypto assets, investing in Runes or related tokens carries risks including price volatility, regulatory uncertainty, technical vulnerabilities, loss of private keys, and potential intellectual property disputes.
Q: Can Runes support DeFi applications on Bitcoin?
A: Potentially. With a reliable fungible token standard in place, developers can build decentralized exchanges, lending protocols, and other DeFi tools directly on Bitcoin—something previously difficult due to technical constraints.
Investment Risks and Final Considerations
While the technological promise of Runes is compelling, Franklin’s report rightly emphasizes caution. Cryptocurrency investments remain highly speculative and volatile. Specific risks include:
- Private key loss: No recovery mechanism exists if keys are lost.
- Regulatory uncertainty: Governments may impose restrictions on token issuance or trading.
- Smart contract-like flaws: Although Runes avoids complex scripting, implementation errors could still lead to exploits.
- Market volatility: Prices can swing dramatically in short periods.
- Trademark and naming conflicts: Popular rune names may lead to disputes or scams.
(Not financial advice)
As always, investors should conduct thorough research and assess their risk tolerance before participating in any emerging crypto project.

Conclusion
The introduction of Runes marks a transformative moment for Bitcoin. By offering a leaner, more efficient way to issue and manage fungible tokens directly on Layer 1, it addresses critical shortcomings of prior attempts like BRC-20. Backed by growing institutional interest—as seen in Franklin’s research—and timed with one of Bitcoin’s most anticipated events, Runes has the potential to catalyze broader adoption of programmable assets on the world’s most secure blockchain.
While still early, the convergence of technical elegance, community momentum, and strategic timing suggests that Runes could indeed become the standard for fungible tokens in the Bitcoin ecosystem—ushering in a new era of utility beyond mere store-of-value narratives.
