BRC-20 Tokens Explained
Learn about BRC-20 tokens and how they use Bitcoin’s blockchain for simpler tokenization. Explore their market growth, security benefits, and popular examples.
Summary: BRC-20 tokens offer a streamlined tokenization method on Bitcoin's blockchain using JSON inscriptions, diverging from smart contract-based standards like ERC-20. Examples include SATS Ordinals and RATS Ordinals.
Despite Bitcoin's scalability issues, the BRC-20 standard's market growth exceeding $2.4 billion underscores its importance in the digital asset space, enhancing Bitcoin's network security by strengthening the fee market for miners.

What is a BRC-20 Token?
A BRC-20 token is an experimental standard for the Bitcoin blockchain, using the Taproot and Ordinals protocol. Unlike smart contract-based tokens, BRC-20 uses JSON inscriptions on satoshis (the smallest Bitcoin units) to create and manage fungible tokens. This approach aligns with Bitcoin's infrastructure, simplifying tokenization by avoiding complex smart contracts.
BRC-20's method contrasts sharply with standards like ERC-20 on Ethereum. While it eases token creation and transfer, it lacks the extensive functionalities of smart contracts. This makes BRC-20 tokens simpler but more limited in use, focusing on fungible token applications within Bitcoin.
However, BRC-20 tokens face Bitcoin's inherent limitations, such as scalability and transaction speed issues. These constraints, along with the lack of advanced features, may affect their broader adoption and versatility.
How do BRC-20 Tokens Work?
BRC-20 tokens operate uniquely within the Bitcoin ecosystem, and their functionality is outlined as follows:
- Deployment: Tokens are created using JSON data inscriptions via the Ordinals protocol on the Bitcoin blockchain. This data includes essential details like the token's name, symbol, and total supply.
- Minting Process: After deployment, new tokens are minted according to predefined rules in the inscription. The initial recipient is chosen by the service used for the inscription, with platforms like Unisat known for their reliability.
- Token Transfer: Transfers occur by updating the JSON data in the inscriptions, acting as a ledger to trace the token's movement across different Bitcoin addresses.
- Storage Mechanism: Unlike Ethereum's ERC-20 tokens that rely on smart contracts, BRC-20 tokens store their information within the Bitcoin blockchain using script files.
BRC-20 tokens lack the advanced functionalities of smart contracts, limiting them to basic features compared to ERC-20 tokens. For detailed information and technical specifics, refer to the BRC-20 GitHub documentation.
Examples of BRC-20 Assets
Key examples of BRC-20 tokens that are gaining attention include:
- SATS Ordinals (SATS): This BRC-20 token, named after the smallest Bitcoin unit - Satoshi, has garnered interest due to its close correlation with Bitcoin's market movements. With a substantial user base, SATS demonstrates the potential for growth within the Bitcoin community.
- RATS Ordinals (RATS): RATS, a unique meme token following the BRC-20 standard, stands out for its scarcity and novelty. Developed using the Ordinals protocol, it operates exclusively on the Bitcoin network, enhancing its appeal to niche token enthusiasts.
- Multibit (MUBI): As a bridge between BRC-20 and ERC-20 tokens, Multibit plays a crucial role in promoting cross-chain interactions. Its functionality in facilitating seamless token transfers between different blockchain networks marks it as a significant asset in the BRC-20 ecosystem.
Are BRC-20s Safe?
BRC-20 tokens leverage the security of the Bitcoin blockchain, benefiting from its stability and decentralized nature. By avoiding complex smart contracts, they potentially reduce vulnerabilities, enhancing their overall security.
However, these tokens depend on external services for tasks like minting and transferring, which can impact their safety. Secure key management and scam awareness are essential for users. Given their experimental nature, caution is advised due to potential undiscovered risks and market volatility.
Who Created BRC-20s?
The BRC-20 token standard was created by @domodata, a blockchain analyst, and introduced on March 8, 2023. This experimental fungible token standard is designed specifically for the Bitcoin blockchain and has attracted significant interest in the cryptocurrency community.
While it has functional limitations compared to Ethereum's ERC-20 standard, BRC-20 represents a noteworthy development in digital assets, contributing to the evolving blockchain landscape.
Bottom Line
In conclusion, BRC-20 tokens introduce a novel approach to tokenization on the Bitcoin blockchain, utilizing JSON inscriptions and avoiding complex smart contracts. While they offer simplicity and leverage Bitcoin's robust security, their experimental nature and limited functionality compared to ERC-20 tokens suggest a cautious approach. As the ecosystem evolves, BRC-20 tokens may play a unique role in the digital asset landscape, but users should stay informed and vigilant about potential risks and developments.
