BRC-20

What is BRC-20?

The BRC-20 standard represents a significant shift in the utility of the Bitcoin blockchain. At its core, the definition of BRC-20 refers to an experimental fungible token standard created specifically for the Bitcoin network. Unlike traditional tokens on Ethereum, which rely on smart contracts, BRC-20 tokens utilize a unique method of embedding data directly onto individual satoshis — the smallest unit of a Bitcoin.

What does BRC-20 mean for crypto?

To gain a full understanding of this technology, one must look at how it changes Bitcoin's identity. For years, Bitcoin was viewed primarily as "digital gold" or a simple peer-to-peer payment system. The emergence of BRC-20 explained a new possibility: the ability to issue and transfer fungible assets directly on the world's oldest blockchain without needing a secondary layer.

The meaning of this standard lies in its simplicity. It was introduced in early 2023 by an anonymous developer named Domo, who sought to see if the Ordinals protocol could be used to create a fungible token ecosystem similar to Ethereum’s ERC-20. While it lacks the programmable complexity of smart contracts, it offers a decentralized way to create and trade tokens that inherit the security and permanence of the Bitcoin network.

How BRC-20 works and its use cases

The technical logic behind BRC-20 is tied to Ordinal Inscriptions. Each token is created by "inscribing" JSON (JavaScript Object Notation) data onto a satoshi. This data defines the token’s supply, name, and minting limits.

There are three main functions within the BRC-20 ecosystem:

• Deploy: Creating the initial token standard and setting parameters like the ticker symbol and maximum supply.
• Mint: Allowing users to claim a portion of the total supply based on the rules set during deployment.
• Transfer: Enabling the movement of tokens between different Bitcoin wallets.

In terms of real-world use cases, the BRC-20 market has been largely driven by memecoins and community-led projects. Assets like ORDI and SATS were among the first to gain significant market capitalization. For businesses and developers, this standard demonstrates that Bitcoin can host a diverse range of assets, potentially opening the door for decentralized finance (DeFi) primitives, loyalty points, or even tokenized real-world assets on the Bitcoin mainnet.

How to use and get BRC-20 tokens

Interacting with BRC-20 tokens requires a specific setup because standard Bitcoin wallets may not recognize the inscribed data. To get started, users generally follow these steps:

1. Set up a compatible wallet: You need a wallet that supports Ordinals and BRC-20, such as UniSat, Xverse, or Leather. These wallets allow you to view the inscriptions rather than just seeing a standard BTC balance.

2. Fund with BTC: Since every BRC-20 transaction is essentially a Bitcoin transaction, you must have a small amount of BTC to cover "gas" or network fees.

3. Access a Marketplace: Users can buy or sell existing tokens on specialized marketplaces. Alternatively, if a token is still in its "minting" phase, users can participate by paying the network fee to claim their share.

Once you own these tokens, they reside in your Bitcoin address. However, it is vital to remember that because they are inscribed on specific satoshis, you must use a "BRC-20 aware" wallet to send them. Using a regular wallet to send Bitcoin could accidentally result in "spending" the satoshi that holds your token, effectively destroying the asset.
