The rise of BRC-20 tokens has sparked widespread curiosity and debate across the cryptocurrency community. As more users explore the potential of tokenizing assets on Bitcoin’s blockchain, a common question emerges: What sets BRC-20 apart from the well-established ERC-20 standard? While both enable the creation of fungible tokens, their underlying architectures, use cases, and ecosystems differ significantly.
This article dives deep into the core distinctions between BRC-20 and ERC-20, exploring how they function, the blockchains they operate on, and their implications for developers, investors, and the future of decentralized innovation.
Understanding Token Standards
A token standard is a set of rules and technical specifications that define how tokens behave on a blockchain. These standards ensure interoperability—meaning wallets, exchanges, and decentralized applications (dApps) can recognize and interact with tokens in a consistent manner.
Key aspects governed by token standards include:
- Total token supply
- Token divisibility (decimal places)
- Transfer mechanisms
- Balance tracking
- Approval and spending controls
By adhering to a standard, developers avoid reinventing the wheel and ensure their tokens integrate seamlessly into existing infrastructure.

What Is ERC-20?
ERC-20 (Ethereum Request for Comments 20) is the most widely adopted token standard in the crypto space. Introduced in 2015, it serves as the foundation for creating fungible tokens on the Ethereum blockchain.
ERC-20 defines a standardized set of functions and events that every compliant token must implement, including:
totalSupply()– returns the total number of tokensbalanceOf(address)– checks an account's token balancetransfer(address, uint256)– sends tokens from one address to anotherapprove(address, uint256)– allows third-party spendingtransferFrom(address, address, uint256)– enables approved transfers
Because of its robust smart contract support, ERC-20 has powered thousands of projects—from stablecoins like USDT and USDC to utility tokens and governance tokens.
Beyond ERC-20, Ethereum also supports other standards like ERC-721 for non-fungible tokens (NFTs) and ERC-1155 for semi-fungible tokens.
Introducing BRC-20: Tokens on Bitcoin
Unlike ERC-20, BRC-20 is not built on smart contracts. Instead, it leverages the Ordinals protocol, which allows data to be inscribed directly onto individual satoshis—the smallest unit of Bitcoin.
BRC-20 is an experimental token standard that enables the creation and transfer of fungible tokens on the Bitcoin blockchain. It was introduced in March 2023 and quickly gained traction during the meme coin surge.
To deploy a BRC-20 token, users inscribe a JSON file into a Bitcoin transaction. This file contains key parameters such as:
p: Protocol identifier (e.g., "brc-20")op: Operation type (deploy, mint, transfer)tick: A four-letter ticker symbolmax: Maximum supplylim: Number of tokens per mint
Once deployed, anyone can mint the token (if within supply limits), and transfers occur through subsequent inscriptions.
Because each operation is recorded as a separate Bitcoin transaction, BRC-20 interactions are immutable but come with higher fees and slower processing times compared to Ethereum-based tokens.
Core Differences Between BRC-20 and ERC-20
| Feature | BRC-20 | ERC-20 |
|---|---|---|
| Blockchain | Bitcoin | Ethereum |
| Smart Contracts | No | Yes |
| Token Creation Method | JSON inscriptions via Ordinals | Solidity smart contracts |
| Transaction Speed | Slower (10 min avg block time) | Faster (~12 sec block time) |
| Fees | High during peak usage | Variable (can be high during congestion) |
| Ecosystem Support | Limited wallets/exchanges | Broad dApp, DeFi, and wallet integration |
| Security Model | Inherits Bitcoin’s PoW security | Ethereum’s proof-of-stake (PoS) security |
These differences reflect contrasting philosophies: BRC-20 extends Bitcoin’s functionality without altering its base layer, while ERC-20 builds new capabilities directly into Ethereum’s programmable environment.
The Meme Coin Surge and BRC-20 Popularity
Much of BRC-20’s growth was fueled by the meme coin craze of 2023. Tokens like ORDI, PEPE, and $WIF gained massive attention, drawing speculative capital into the Bitcoin ecosystem.
While many view these tokens as novelty-driven or speculative plays, their popularity highlights a growing desire to unlock new use cases for Bitcoin beyond being “digital gold.”
Even the creator of BRC-20, known pseudonymously as Domo, described it as a “fun experiment.” Yet, this experiment has ignited serious discussions about Bitcoin’s potential for innovation.

Network Congestion and Scalability Challenges
The rapid adoption of BRC-20 tokens led to significant network congestion on Bitcoin. In April and May 2023, inscription activity peaked, with BRC-20-related transactions accounting for over 50% of daily on-chain activity.
This surge caused transaction fees to spike dramatically—some reports indicated fees reaching $15–$20 for small transfers, making microtransactions impractical.
Critics argue that BRC-20 misuse wastes limited block space better reserved for payments. However, supporters counter that:
- Bitcoin has historically evolved through experimentation
- Upgrades like SegWit, Taproot, and Lightning Network improve scalability
- Market demand determines what data gets prioritized on-chain
As Layer 2 solutions mature, they may alleviate pressure on the main chain while preserving decentralization.
Innovation vs. Controversy: The Future of BRC-20
Despite the controversy, BRC-20 has undeniably pushed the boundaries of what’s possible on Bitcoin. It demonstrates that even a non-programmable blockchain can support tokenization through creative engineering.
Ordinals and inscriptions have opened doors to:
- Digital collectibles on Bitcoin
- Decentralized identity experiments
- On-chain art and cultural artifacts
- New forms of community-driven value creation
While BRC-20 may not replace ERC-20 in utility or functionality, it represents a cultural shift—proving that innovation can emerge organically from decentralized communities.
Frequently Asked Questions (FAQ)
What is the main difference between BRC-20 and ERC-20?
The primary difference lies in their underlying blockchains and technical implementation. BRC-20 operates on Bitcoin using data inscriptions via the Ordinals protocol, without smart contracts. In contrast, ERC-20 runs on Ethereum using programmable smart contracts, enabling complex logic and broader DeFi integration.
Can BRC-20 tokens be used in DeFi applications?
Currently, BRC-20 tokens have limited DeFi compatibility due to the lack of smart contract functionality. They cannot directly participate in lending, staking, or automated market makers like ERC-20 tokens can. However, bridging solutions may emerge in the future to connect them to Ethereum or other ecosystems.
Are BRC-20 tokens secure?
Yes, BRC-20 tokens inherit Bitcoin’s robust security model, secured by its proof-of-work consensus. However, because transactions rely on manual inscription parsing and lack formal verification standards, there’s a higher risk of user error or fraudulent tokens compared to audited ERC-20 contracts.
How do I store BRC-20 tokens?
You need a wallet that supports Bitcoin Ordinals, such as Unisat Wallet, Xverse, or Leather. Standard Bitcoin wallets that only handle BTC balances will not display or manage BRC-20 tokens properly.
Why are BRC-20 transaction fees so high?
Fees are high because each BRC-20 action (deploy, mint, transfer) requires a full Bitcoin transaction, often with large data payloads. During periods of high network demand—like NFT mints or popular token launches—users compete for block space, driving up costs.
Is BRC-20 officially supported by Bitcoin developers?
No. BRC-20 is a community-driven experiment built on top of existing Bitcoin features. It is not endorsed by core Bitcoin developers. Some express concerns about bloating the blockchain with non-payment data, while others see it as permissionless innovation in action.
Final Thoughts: Two Paths of Tokenization
BRC-20 and ERC-20 represent two distinct philosophies in blockchain design:
- ERC-20 embraces programmability and composability—ideal for complex financial systems.
- BRC-20 explores minimalism and data permanence—leveraging Bitcoin’s security for simple token experiments.
While ERC-20 remains dominant in utility and adoption, BRC-20 showcases the power of grassroots innovation. Whether it evolves into a sustainable ecosystem or remains a speculative phase, it has already left a mark on Bitcoin’s narrative.
As blockchain technology advances, we’re likely to see more hybrid models—where security, scalability, and functionality converge across networks.
