What Are BRC-20 Tokens? A Deep Dive into the Bitcoin Memecoin Machine
BRC-20 tokens represent a relatively new cryptocurrency type that can be both created and traded on the Bitcoin blockchain. Drawing inspiration from Ethereum's ERC-20 standard, BRC-20 tokens operate using a distinct protocol known as Ordinals, which enables the inscription of data on satoshis, Bitcoin's smallest unit, and seamlessly functions within the Bitcoin blockchain.
The BRC-20 market has experienced exponential growth since its introduction in March 2023, driven by an anonymous developer named Domo. To date, the aggregate market cap of BRC-20 tokens has surged to over $1.35 billion as of November 2023, firmly grasping the attention of the blockchain and cryptocurrency community.
BRC-20 transactions now constitute a substantial portion of Bitcoin transactions, contributing significantly to network congestion. In recent times, BRC-20 transactions have dominated the Bitcoin mempool, as evident from data on Dune Analytics.

The launch of any new token standard in the blockchain ecosystem, however, is typically a hotbed of confusion, hastily-minted memecoins, and conflicting information. Join us in a KuCoin deep dive into BRC-20 as we dismantle the hype surrounding this new token standard and find out what BRC-20 tokens are, how BRC-20 tokens work, and what BRC-20 tokens actually do.
What Are BRC-20 Tokens?
BRC-20 tokens are a unique and revolutionary type of token standard that utilizes a recent innovation within the Bitcoin development community known as Ordinals. Ordinal Inscriptions are digital assets inscribed directly onto satoshis, the smallest unit of Bitcoin.
What Are Token Standards?
The regulations and functions governing a cryptocurrency token's behavior are referred to as token standards. To fully understand token standards, it’s necessary to understand the fundamentals of smart contract standards. Smart contract standards are guidelines that must be followed by a smart contract in order for it to perform as intended on a given blockchain network.
These standards help create new tokens, name registries, and package formats, among other things, by providing a set of guidelines for the smart contract to follow. With these standards, anyone with enough knowledge can create their own token.
Token standards are a subset of smart contract standards, specifically focused on creating, issuing, and deploying tokens on the blockchain network. Some of the most common token standards are ERC-20, ERC-721, ERC-777, and ERC-1155, which are frequently used in Ethereum-based smart contracts.
BRC-20 Tokens, Explained
Unlike traditional tokens stored on separate blockchains, BRC-20 tokens leverage the Taproot upgrade on the Bitcoin blockchain to inscribe their data. Taproot introduced the witness feature, which enables the storage of associated data within a Bitcoin transaction.
By leveraging Ordinals and Inscriptions, the BRC-20 token standard operates as an experimental fungible token on the Bitcoin base chain. It deploys, mints, and transfers tokens using JSON data inscribed as Ordinals.
The BRC-20 token standard was announced on March 8th, 2023, by Twitter user @domodata, demonstrating fungibility on Bitcoin with Ordinals. While it borrows its name from Ethereum's ERC-20 token standard, the BRC-20 token standard does not possess the same smart contract capabilities as the EVM standard.

What Can BRC-20 Tokens Do?
- Let developers create tokens based on the Bitcoin blockchain, similar to ERC-20 tokens on Ethereum.
- Facilitate seamless trading between two tokens of the same type.
- Enable token creators to mint and trade BRC-20 tokens directly from a Bitcoin wallet.
What Can't BRC-20 Tokens Do?
- BRC-20 tokens cannot interact with smart contracts like Ethereum's ERC-20 tokens.
- While Ordinals may facilitate the creation of NFTs on the Bitcoin blockchain, BRC-20 tokens are designed to be fungible and tradeable for other tokens of the same type.
Bitcoin’s BRC-20 vs. Ethereum’s ERC-20 Token Standard
Here are some key differences between BRC-20 and ERC-20 tokens:
BRC-20 vs. ERC-20: Underlying Blockchain
BRC-20 and ERC-20 are two distinct token standards with significant differences. BRC-20 tokens operate on the Bitcoin blockchain, while ERC-20 tokens operate on the Ethereum blockchain.
BRC-20 tokens are secured by Bitcoin's Proof of Work (PoW) consensus mechanism, while ERC-20 tokens are secured by Ethereum's Proof of Stake (PoS) consensus mechanism. Unlike ERC-20 tokens, BRC-20 tokens cannot interact directly with smart contracts. Instead, BRC-20 tokens leverage Inscriptions through the Ordinals protocol to function as fungible assets.
Smart Contract Functionality
Unlike conventional token standards on Ethereum Virtual Machine (EVM) chains, the BRC-20 token standard operates differently. It doesn't rely on smart contracts to enforce rules and regulations. Instead, it utilizes a script file within Bitcoin and assigns tokens to satoshis, enabling seamless transfers between users.
Although BRC-20 tokens are not currently equipped with smart contract functionality, they represent a move towards Bitcoin-based tokens operating on the Bitcoin network rather than being "NFTs on Bitcoin."
Support and Versatility
Regarding support and versatility, ERC-20 tokens are more widely acknowledged and utilized than BRC-20 tokens. This is primarily due to the technical limitations and experimental nature of the BRC-20 token standard. However, as the BRC-20 ecosystem continues to expand, BRC-20 tokens may develop additional features to emulate certain functionalities of ERC-20 tokens.

Cons of BRC-20 Tokens
1. Network Congestion: The introduction of BRC-20 tokens can contribute to network congestion on the Bitcoin blockchain, leading to slower transaction processing times and higher transaction fees. For instance, during the four-day period between April 29 and May 2, BRC-20 token swaps constituted more than 50% of all network transactions, resulting in congestion and delays for regular BTC transactions.
2. Gas Fee Increase: BRC-20 tokens consuming block space can result in higher gas fees, reducing cost efficiency and accessibility for users conducting transactions on the Bitcoin blockchain. On 8 May 2023, Bitcoin’s transaction fees surged to a record high of $30, with over 300,000 pending transactions, mostly because of BRC-20 token swaps.
3. Potential for Scams: The popularity of BRC-20 tokens may attract the attention of scammers seeking to exploit unsuspecting users, highlighting the importance of conducting thorough research and due diligence before participating in token-related activities.
4. Ecosystem Fragmentation: A large number of BRC-20 tokens may result in a fragmented ecosystem, with many tokens having limited use cases and struggling to gain widespread adoption and utility.
What’s Next for BRC-20 Tokens?
While BRC-20 tokens are gaining attention for their potential use cases, they currently cannot interact with smart contracts. This limitation restricts their functionality within ecosystems like DeFi, where smart contracts play a vital role in executing complex financial transactions.
The emergence of BRC-20 tokens has introduced fungible and non-fungible tokens (NFTs) into the Bitcoin ecosystem, thanks to the Ordinals protocol. However, if BRC-20 tokens continue to gain traction and widespread adoption, they could be upgraded to include smart contract functionality. Several ongoing projects are actively exploring the integration of DeFi, NFTs, applications, and smart contract functionality with the Bitcoin blockchain, with initiatives like Stacks (STX) leading the way.
Further developments in BRC-20 tokens could propel them to a level of functionality similar to the ERC-20 token standard, opening the door to more advanced DeFi applications being built on the Bitcoin blockchain. BRC-20 tokens are primarily associated with the issuance of memecoins, but their future could see them evolve into a more versatile asset within the cryptocurrency ecosystem.
