BRC-20 tokens represent a relatively new type of cryptocurrency that can be created and traded on the Bitcoin blockchain. Inspired by Ethereum's ERC-20 token standard, BRC-20 tokens operate using a distinct protocol known as Ordinals. This protocol allows data to be inscribed on satoshis, the smallest units of Bitcoin, and functions seamlessly within the Bitcoin network.
The BRC-20 token market has experienced exponential growth since its introduction in March 2023, driven by an anonymous developer known as Domo. As of late 2023, the total market capitalization of BRC-20 tokens surpassed $1.35 billion, capturing significant attention from the broader blockchain and cryptocurrency community.
BRC-20 transactions now constitute a substantial portion of Bitcoin's network activity, contributing to periods of network congestion. Recently, these transactions have dominated Bitcoin's mempool, as reflected in data from analytics platforms.
However, the launch of new token standards within blockchain ecosystems often brings confusion and controversy, with hastily created memecoins and misleading information. This article cuts through the hype to explain what BRC-20 tokens are, how they work, and their potential applications.
What Are BRC-20 Tokens?
BRC-20 tokens are a unique and innovative token standard. They utilize a recent development within the Bitcoin community called Ordinals. Ordinal inscriptions are digital assets inscribed directly onto individual satoshis.
Explaining Token Standards
Token standards refer to the rules and functions that govern the behavior of cryptocurrency tokens. To fully understand token standards, one must grasp the fundamentals of smart contract standards. Smart contract standards compile the instructions that smart contracts must follow to operate as intended on a specific blockchain network.
These standards facilitate the creation of new tokens, name registries, package formats, and more by providing a set of guidelines for smart contracts to execute. With these standards, anyone possessing sufficient technical knowledge can create their own tokens.
Token standards are a subset of smart contract standards, specifically focusing on the creation, issuance, and deployment of tokens on a blockchain network. Some of the most popular token standards include ERC-20, ERC-721, ERC-777, and ERC-1155, typically used within Ethereum-based smart contracts.
The Mechanics of BRC-20 Tokens
Unlike traditional tokens stored on separate blockchains, BRC-20 tokens leverage the Taproot upgrade on the Bitcoin blockchain to inscribe data. Taproot introduced the witness field, which allows for the storage of related data within Bitcoin transactions.
By utilizing Ordinals and inscriptions, the BRC-20 token standard functions as an experimental fungible token on the Bitcoin base layer. The standard implements token deployment, minting, and transfers using JSON data inscribed as Ordinals.
The BRC-20 token standard was announced by Twitter user @domodata on March 8, 2023, highlighting Bitcoin's fungibility with Ordinals. Although it borrows its naming convention from Ethereum's ERC-20 standard, the BRC-20 standard does not possess the same smart contract capabilities as token standards on the Ethereum Virtual Machine (EVM).
Capabilities and Limitations of BRC-20 Tokens
What BRC-20 Tokens Can Do:
- Enable developers to create their own tokens on the Bitcoin blockchain, a feature similar to ERC-20 tokens on Ethereum.
- Facilitate seamless transactions between two tokens of the same type.
- Allow token creators to mint and trade BRC-20 tokens directly from a Bitcoin cryptocurrency wallet.
What BRC-20 Tokens Cannot Do:
- They cannot interact with smart contracts like Ethereum's ERC-20 tokens.
- While Ordinals can facilitate the creation of NFTs on the Bitcoin blockchain, BRC-20 tokens are designed to be fungible and tradable with other tokens of the same type.
BRC-20 vs. ERC-20: A Comparative Analysis
Here are some key differences between Bitcoin's BRC-20 and Ethereum's ERC-20 tokens:
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, whereas ERC-20 tokens are secured by Ethereum's Proof-of-Stake (PoS) consensus. Unlike ERC-20 tokens, BRC-20 tokens cannot interact directly with smart contracts. Instead, they leverage inscriptions through the Ordinals protocol to function as fungible assets.
Smart Contract Functionality
Unlike conventional token standards on the EVM chain, the BRC-20 token standard operates differently. It does not rely on smart contracts to enforce rules and regulations. Instead, BRC-20 uses script files within Bitcoin and assigns tokens to satoshis, enabling seamless transfers between users.
Although BRC-20 tokens currently lack smart contract functionality, they represent an innovative step towards Bitcoin-based tokens that operate on the Bitcoin network, moving beyond the concept of "NFTs on Bitcoin."
Support and Flexibility
In terms of support and flexibility, ERC-20 tokens are more widely adopted 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, these tokens may evolve to incorporate additional features that mimic certain functions of ERC-20 tokens.
Top BRC-20 Projects and Tokens by Market Capitalization
The ease of minting BRC-20 tokens has led to the rapid proliferation of BRC-20 projects, with many emerging since March 2023. Tracking platforms boast an impressive record of over 40 million Ordinals inscriptions. Since its launch, there have been tens of millions of BRC-20 transactions on the Bitcoin network, with transaction fees amounting to significant sums.
The growing interest in BRC-20 tokens has injected momentum into the expanding ecosystem. Here is a list of notable BRC-20 tokens based on market activity:
- SATS: Aims to facilitate micro-transactions and enable the representation of smaller Bitcoin units on the blockchain.
- ORDI: One of the oldest BRC-20 tokens, created as an integral part of the Ordinals Protocol, facilitating trading within its decentralized digital asset marketplace.
- RATS: A memecoin inspired by animals (rats) operating on the Bitcoin blockchain, complying with the BRC-20 standard.
