The cryptocurrency landscape is continuously evolving, and one of the most significant recent developments is the emergence of BRC-20 tokens. Built directly on the Bitcoin blockchain, these tokens represent a new frontier in tokenization, expanding Bitcoin's utility beyond simple peer-to-peer transactions.
This guide explores everything you need to know about BRC-20 tokens, from their technical foundations to their potential future.
What Is the BRC-20 Token Standard?
BRC-20 is an experimental token standard on the Bitcoin blockchain. The name stands for Bitcoin Request for Comment 20. It allows users to create, mint, and transfer fungible tokens by inscribing data onto individual satoshis—the smallest unit of a Bitcoin.
This is achieved using the Ordinals protocol, which enables data like text, code, images, and JSON to be permanently attached to a satoshi. For a token to be a BRC-20, it must use a specific JavaScript Object Notation (JSON) format to define its properties.
What Are BRC-20 Tokens?
BRC-20 tokens are digital assets created and managed according to the BRC-20 standard. Unlike traditional Bitcoin transactions, which record the transfer of value, BRC-20 transactions inscribe JSON data that defines the token's characteristics, such as its name (e.g., ORDI), ticker symbol, total supply, and minting limits.
This process turns a simple satoshi into a carrier of a unique digital asset, bridging the world of Bitcoin with the functionality of tokenization.
The Origin and Growth of BRC-20
The BRC-20 standard was created by an anonymous blockchain analyst known as Domo in March 2023. The first token launched under this standard was ORDI.
The introduction of BRC-20 tokens sparked immense interest. Quickly, Bitcoin wallet providers integrated tools to support these new assets. The following months saw an explosion of new tokens, including meme-inspired coins like PEPE and MEME.
This rapid growth had a significant side effect: it congested the Bitcoin network. The process of inscribing data for BRC-20 tokens and Ordinals NFTs consumes substantially more block space than standard Bitcoin transactions, leading to a dramatic increase in transaction fees and network congestion throughout 2023.
How Do BRC-20 Tokens Work?
The functionality of BRC-20 tokens hinges on two key technologies: the Ordinals protocol and inscriptions.
- The Ordinals Protocol: This system allows for the numbering and tracking of individual satoshis, making it possible to inscribe data onto a specific one.
- Inscriptions: This is the act of attaching data to a satoshi. For BRC-20 tokens, this data is a JSON script that operates as a smart contract would on other blockchains, defining the token's core parameters.
To create a BRC-20 token, a user must:
- Write a JSON script specifying the token’s name, ticker, total supply, and mint limit.
- Inscribe this deployment script onto a satoshi.
- Pay the associated Bitcoin network transaction fee.
Once deployed, others can mint tokens by inscribing minting transactions, and holders can transfer them by inscribing transfer transactions.
Key Features of BRC-20 Tokens
- Bitcoin-Native: BRC-20 tokens are natively built on Bitcoin, leveraging its robust security and widespread infrastructure without requiring a separate blockchain.
- Simplicity: The standard uses a straightforward JSON-based system, making it relatively accessible for users to issue and transfer tokens without needing deep smart contract expertise.
- Security: They inherit the formidable security of the Bitcoin network, which is secured by a vast global network of miners using Proof-of-Work.
- Immutability: Once inscribed, the token data is permanently embedded on the Bitcoin blockchain, making it censorship-resistant and durable.
The BRC-20 Ecosystem and Market
The BRC-20 ecosystem has expanded at a remarkable pace. To date, thousands of different BRC-20 tokens have been created, with the total market capitalization for the standard reaching into the billions of dollars.
The first token, ORDI, achieved a multi-hundred-million dollar market cap. This growth, while impressive, has been a double-edged sword, contributing to the aforementioned network congestion and high fees on the Bitcoin blockchain.
Primary Use Cases for BRC-20 Tokens
BRC-20 tokens are being explored for various applications:
- Community Fundraising: Projects can use BRC-20 tokens to raise funds from a global community, similar to Initial DEX Offerings (IDOs) on other chains.
- Decentralized Finance (DeFi): While limited by the lack of native smart contracts, BRC-20 tokens can be integrated into DeFi protocols built on Bitcoin Layer 2 solutions or bridges to other chains for lending, borrowing, and trading.
- Utility Tokens: They can serve as in-app currency for platforms like NFT marketplaces or blockchain-based games operating within the Bitcoin ecosystem.
- Community and Meme Tokens: A significant portion of BRC-20 tokens are community-driven meme coins, which aim to build cultural value and engaged communities, similar to their counterparts on Ethereum or Solana.

Advantages and Limitations
Advantages
- Security: Built on Bitcoin's battle-tested, secure network.
- Network Effects: Benefits from Bitcoin's massive adoption and brand recognition.
- Simplicity: The JSON-based standard is easier for many developers and users to understand compared to complex smart contract languages.
Limitations
- No Smart Contracts: The standard does not support complex, programmable logic, limiting its functionality compared to tokens on Ethereum or Solana.
- Network Congestion: BRC-20 activity can clog the Bitcoin network, leading to slow transaction times and high fees for all users.

BRC-20 vs. ERC-20: A Brief Comparison
While both are token standards, BRC-20 and Ethereum's ERC-20 are fundamentally different.
- Smart Contracts: ERC-20 tokens are powered by Turing-complete smart contracts, enabling complex functionality. BRC-20 tokens rely on inscribed JSON data and lack this programmability.
- Underlying Blockchain: ERC-20 operates on Ethereum, while BRC-20 operates on Bitcoin. This leads to differences in transaction speed, cost, and overall philosophy.
- Transaction Fees: During times of high demand, Bitcoin transaction fees for BRC-20 operations can far exceed typical Ethereum gas fees.
BRC-20 vs. Bitcoin Runes
A new protocol called Runes was launched in 2024 to address some of BRC-20's limitations.
- BRC-20: Uses an "account-based" model, similar to Ethereum. It can create many small, "dust" UTXOs (unspent transaction outputs), which clutter the network.
- Runes: Uses a UTXO-based model that is more efficient for the Bitcoin network. It is designed to be more private and compatible with the Lightning Network.
The Future of BRC-20: Potential and Challenges
The future of BRC-20 is a topic of intense debate.
- Opportunities: Its growth demonstrates a strong desire to build more functionality on Bitcoin. Continued development of Layer 2 solutions could help overcome its scalability issues and unlock new use cases.
- Challenges: The protocol's inherent limitations, particularly its contribution to network congestion and lack of smart contract functionality, are significant hurdles. Competing standards like Runes may offer more efficient alternatives.
Success will likely depend on the broader Bitcoin community's ability to scale the network and develop solutions that mitigate the impact of inscription-based protocols.
Frequently Asked Questions
What is the difference between an Ordinal and a BRC-20 token?
An Ordinal refers to a single satoshi that has had any type of data (image, text, video, code) inscribed onto it, often creating an NFT. A BRC-20 token is a specific type of Ordinal that uses a JSON inscription to create a fungible, interchangeable token.
Do I need a special wallet for BRC-20 tokens?
Yes, you cannot store BRC-20 tokens in a regular Bitcoin wallet. You need a wallet that supports the Ordinals protocol, such as UniSat, Xverse, or Ordinals Wallet.
Why did Bitcoin transaction fees get so high?
A primary reason for the fee spikes in 2023 was the surge in demand for BRC-20 and Ordinals inscriptions. These data-heavy transactions compete for limited block space, driving up fees for everyone using the network.
Can BRC-20 tokens be bridged to other blockchains?
Yes, several cross-chain bridges have emerged to facilitate the movement of BRC-20 tokens to other chains like Ethereum, where they can be used in a wider variety of DeFi applications.
Is investing in BRC-20 tokens risky?
Yes, extremely. The standard is experimental, the market is highly volatile and speculative, and many tokens are meme coins with no fundamental value. Always conduct thorough research and never invest more than you can afford to lose.
What is the long-term goal of the BRC-20 standard?
The goal is to expand the utility of the Bitcoin network beyond a store of value and payment system, enabling it to participate in the broader tokenized economy, albeit in a different way than smart contract platforms.
