What Is BRC-20? Definition and Meaning in Cryptocurrency

·

The BRC-20 token standard has sparked growing interest in the cryptocurrency world, especially among Bitcoin enthusiasts exploring new layers of functionality on the original blockchain. While Bitcoin was initially designed for peer-to-peer transactions, innovations like the Taproot upgrade and the Ordinals protocol have expanded its capabilities—leading to the emergence of BRC-20 tokens. This article explores what BRC-20 is, how it works, its differences from ERC-20, and the limitations that shape its future potential.

Understanding the BRC-20 Standard

BRC-20, short for Bitcoin Request for Comment, is a token standard that enables the minting of fungible tokens on the Bitcoin blockchain. Inspired by Ethereum’s widely adopted ERC-20 standard, BRC-20 introduces a new way to create and manage digital assets directly on Bitcoin—without requiring smart contracts.

The standard was introduced in March 2023 by a pseudonymous Twitter user named domo (@domodata). Unlike traditional token standards built on programmable blockchains, BRC-20 leverages the Ordinals protocol, which allows users to inscribe data—such as JSON text—onto individual satoshis (the smallest unit of Bitcoin). These inscriptions effectively function as tokens, enabling deployment, minting, and transfers within the Bitcoin network.

How Does BRC-20 Work?

At its core, BRC-20 uses plain JSON (JavaScript Object Notation) data inscriptions to simulate smart contract-like behavior on Bitcoin. Since Bitcoin does not natively support smart contracts, this method creatively bypasses that limitation by encoding token logic into readable text stored directly on-chain.

Here’s an example of a typical BRC-20 deployment inscription for the first BRC-20 token, ORDI:

{
  "p": "brc-20",
  "op": "deploy",
  "tick": "ordi",
  "max": "21000000",
  "lim": "1000"
}

Let’s break down what each field means:

This simple structure allows developers and creators to launch their own tokens with minimal technical overhead. After ORDI’s launch, tens of thousands of BRC-20 tokens were quickly deployed, many of them meme coins capitalizing on community hype.

Popular BRC-20 tokens beyond ORDI include DFUK, OSHI, PEPE, and MEME, reflecting a trend toward speculative and community-driven projects.

BRC-20 vs ERC-20: Key Differences

While both standards facilitate fungible tokens, their underlying architectures and ecosystems differ significantly.

ERC-20 tokens benefit from Ethereum’s robust smart contract infrastructure, enabling advanced features like automated transfers, staking, and integration with DeFi platforms. In contrast, BRC-20 tokens are more rudimentary. They rely on external tools and manual processes for tracking balances and executing transfers, making them less efficient but intriguing due to their novelty and connection to Bitcoin’s security.

Limitations of the BRC-20 Standard

Despite the excitement surrounding BRC-20, several critical limitations raise questions about its long-term viability.

1. Experimental Nature

The creator of BRC-20 explicitly described it as an experimental framework—not a formal standard. It was designed to explore whether state management could be achieved through inscriptions rather than being a scalable solution for tokenization on Bitcoin.

2. Semi-Fungibility

Although labeled as fungible, BRC-20 tokens are more accurately described as semi-fungible. Each token unit is tied to a specific inscription, meaning they aren’t perfectly interchangeable. For example, if you want to buy 500 ORDI tokens, you need to find someone selling exactly that amount under a matching inscription—limiting liquidity and complicating trades.

3. Scalability and Network Impact

Inscribing data onto the Bitcoin blockchain increases transaction size and congestion. As more users mint BRC-20 tokens, block space demand rises, potentially leading to higher fees and slower confirmation times—a concern for core Bitcoin users who prioritize fast, low-cost payments.

4. Lack of Built-in Transfer Mechanisms

Unlike ERC-20, BRC-20 does not have a native transfer function. Transfers require separate inscriptions and depend on wallet providers or third-party services to interpret balance changes correctly. This adds friction and increases the risk of errors or fraud.

Frequently Asked Questions (FAQ)

What does BRC-20 stand for?

BRC-20 stands for Bitcoin Request for Comment 20. It follows the naming convention of Ethereum’s ERC-20 but applies to experimental token standards on the Bitcoin network.

Can I create my own BRC-20 token?

Yes, anyone can deploy a BRC-20 token by crafting a valid JSON inscription and broadcasting it to the Bitcoin network via a compatible wallet or service. However, success depends on community adoption and visibility.

Is BRC-20 supported by all Bitcoin wallets?

No. Only specialized wallets that recognize Ordinals and BRC-20 inscriptions can display and manage these tokens. Standard Bitcoin wallets will treat them as regular transactions with embedded data.

Are BRC-20 tokens secure?

They inherit Bitcoin’s high level of network security due to Proof-of-Work consensus. However, individual tokens may lack utility or value, so investors should exercise caution.

How are BRC-20 tokens different from NFTs on Bitcoin?

Both use the Ordinals protocol, but NFTs represent unique, non-fungible assets inscribed on individual satoshis. BRC-20 tokens are intended to be fungible—though semi-fungibility remains a challenge.

Should I invest in BRC-20 tokens?

Investing in BRC-20 tokens carries high risk due to their speculative nature, limited functionality, and uncertain regulatory status. Always conduct thorough research before participating.

The Future of BRC-20

The rise of BRC-20 reflects a broader trend: extending Bitcoin’s utility beyond simple value transfer. While currently dominated by meme coins and speculative projects, the concept could inspire more robust tokenization models on Bitcoin in the future—especially as tooling improves and community interest grows.

However, widespread adoption faces hurdles. Without native smart contract support or standardized transfer protocols, BRC-20 remains a niche experiment rather than a foundational shift in how we use Bitcoin.

That said, innovation often begins at the edges. If future upgrades enhance inscription efficiency or enable better composability, BRC-20—or its successors—might play a role in bringing programmable assets to the most secure blockchain in existence.
