The rise of Ordinals and Inscriptions has brought a wave of innovation to the Bitcoin ecosystem. BRC-20 tokens represent the latest development in this movement, capturing significant attention across the crypto community. This experimental token standard enables the deployment, minting, and transfer of fungible tokens on the Bitcoin blockchain.
While the total market capitalization of BRC-20 tokens briefly approached $1 billion, these tokens remain relatively simple. They lack smart contract functionality, distinguishing them from more established standards like ERC-20 or BEP-20. The recent minting frenzy in early May caused substantial congestion in Bitcoin's mempool, driving network transaction fees to surge dramatically.
What Are Ordinals and Inscriptions?
Ordinals refer to an open-source protocol that enables the tracking of individual satoshis (sats) on the Bitcoin blockchain. Each satoshi is assigned a unique identifier based on what creator Casey Rodarmor calls "Ordinal Theory." These individual sats can then be "inscribed" with arbitrary content—such as text, images, or videos—to create digital artifacts known as Inscriptions, effectively functioning as Bitcoin-native NFTs.
This innovation has opened new possibilities for Bitcoin, expanding its use beyond simple peer-to-peer transactions.
The Emergence of BRC-20 Tokens
With the advent of Inscriptions enabling NFTs on Bitcoin, the natural question became: what about fungible tokens? This is where BRC-20 enters the picture.
On March 9, an anonymous Twitter user known as domo introduced the concept of BRC-20—a method for creating a fungible token standard on top of the Ordinals Protocol. The idea involves inscribing JSON data onto individual sats to deploy, mint, and transfer fungible BRC-20 tokens.
The first token deployed was $ORDI, featuring a 1,000 token mint limit per transaction and a maximum supply of 21 million tokens—a clear homage to Bitcoin's own supply limit. The launch created immediate excitement, with all ORDI tokens minted in less than 24 hours. Soon after, other tokens emerged including $MEME, $PEPE, and $PUNK.
Current Market Landscape
Despite being conceptualized only months ago, the BRC-20 market has developed rapidly. As of mid-May 2023, over 18,000 BRC-20 tokens existed with a total market capitalization of approximately $500 million. While this figure reached nearly $1 billion in early May, the market has since corrected to find a more stable equilibrium.
$ORDI remains the market leader by both capitalization and trading volume, recently achieving listings on several exchanges. However, the market remains in its earliest stages with limited infrastructure and significant volatility.
Comparative Analysis: BRC-20 vs. Other Token Standards
Although the name "BRC-20" deliberately echoes Ethereum's ERC-20 standard, the two differ significantly:
Blockchain Foundation: BRC-20 tokens exist on Bitcoin, while ERC-20 tokens reside on Ethereum and BEP-20 tokens on BNB Smart Chain. This fundamental difference affects transaction speeds, fees, and overall user experience.
Functionality: ERC-20 and BEP-20 tokens utilize smart contracts, enabling complex programmable functions and various operations. BRC-20 tokens lack smart contract capabilities and offer relatively limited functionality.
Maturity and Infrastructure: Established token standards benefit from years of development including DEXs, centralized exchange compatibility, fiat on-ramps, and cross-chain capabilities. BRC-20 tokens, being only months old, lack this extensive infrastructure.
Impact on Bitcoin Network Metrics
Homogeneous vs. Heterogeneous Inscriptions
The emergence of BRC-20 tokens has dramatically shifted the composition of the Inscription market. While image-based inscriptions dominated initially, text-based inscriptions (primarily associated with BRC-20 tokens) now represent the overwhelming majority. Total inscriptions have grown from approximately 650,000 in late March to over 6.1 million by mid-May—nearly a tenfold increase.
Mempool Congestion
Bitcoin's mempool—the waiting room for unconfirmed transactions—has seen substantially increased activity throughout 2023. The recent interest in Inscriptions and BRC-20 tokens has caused a significant spike in unconfirmed transactions, increasing competition for block space.
Transaction Fees
The increased demand for block space has naturally driven transaction fees higher. While Bitcoin transaction fees have spiked previously during bull markets (December 2017 and April 2021), the recent increase is notable for occurring during what many consider a bear market.
From a miner perspective, transaction fees have increased from 1-2% of total rewards to over 20% in May. This development is particularly significant for Bitcoin's long-term security model, as block rewards will continue decreasing until eventually reaching zero. Higher transaction fees may help sustain miner revenue as block rewards diminish.
Community Response
The Bitcoin community has responded to these developments with diverse perspectives:
The "Pro-Fee" Camp
Many community members welcome increased fees as essential for Bitcoin's long-term security sustainability. With block rewards decreasing every four years, transaction fees must eventually compensate miners adequately to secure the network. Some blocks in early May even generated higher fees than the 6.25 BTC block reward—a remarkable achievement considering fees typically represented 1-2% of miner revenue throughout 2022.
The "Low-Fee" Camp
Others criticize these developments as偏离 Bitcoin's intended purpose as hard money and a non-sovereign currency. This group believes data-intensive transactions related to Ordinals primarily congest the Bitcoin network and increase fees, ultimately hindering peer-to-peer transactions.
Some have even suggested that Bitcoin core developers should censor Ordinal-related transactions—a proposal that contradicts Bitcoin's fundamental ethos of decentralization.
The Builder Perspective
Perhaps most importantly, developers are building tools and infrastructure to advance these innovations. Key contributors include:
- Casey Rodarmor: Creator of the Ordinals Protocol
- Domo: Conceptualizer of the BRC-20 standard
- UniSat Wallet: Early participant providing wallet functionality, a BRC-20 marketplace, and indexing tools
- ALEX: A project building DeFi on Bitcoin's Layer 2 (Stacks) with recent BRC-20 DEX testing
- Rare Satoshi Society: Focused on identifying and collecting rare satoshis based on Ordinal rarity classifications

Risks and Challenges
Despite the excitement, BRC-20 tokens involve substantial risks:
Limited Infrastructure
As an experimental token standard only months old, BRC-20 lacks mature infrastructure. Most trading occurs over-the-counter via Discord servers rather than through established exchanges. The absence of robust indexing creates challenges for tracking tokens and holders consistently across platforms.
No Intrinsic Utility
Most currently traded BRC-20 tokens are meme tokens with no fundamental utility. Their values primarily reflect social media sentiment and community hype rather than underlying value, creating vulnerability to sudden crashes.
High Fraud Risk
The experimental nature of these tokens creates elevated fraud risks. OTC trading on Discord servers has already resulted in numerous scams. Projects building infrastructure for Ordinals or BRC-20 may present security vulnerabilities at this early stage.
Future Outlook
Bitcoin Layer 2 Solutions
The recent congestion highlights Bitcoin's scaling challenges. If Bitcoin aims to become a global peer-to-peer payment system for millions or billions of users, Layer 2 solutions will be essential. Promising developments include:
- Lightning Network: Continued growth with Binance recently announcing integration plans
- Stacks: Upcoming sBTC release potentially enabling more decentralized L2 Bitcoin usage
- Rootstock, Liquid Network, and Rollkit: Additional scaling approaches
Infrastructure Development
Substantial infrastructure development is needed for BRC-20 tokens to mature. Critical requirements include:
- Functional, efficient DEXs beyond current test versions
- Robust, decentralized indexing to establish agreed global state
- Smoother trading processes moving beyond OTC Discord transactions
Several projects are working on these challenges, with the Bitcoin Frontier Fund recently accepting eight startups focused on Ordinals lending, Bitcoin Web3 gaming toolkits, and cross-chain bridging.
Token Design Innovations
The current BRC-20 standard remains relatively simple with limited flexibility. Key areas for innovation include:
- Moving beyond fair minting to allow team allocations and whitelist functionality
- Implementing token burning mechanisms despite lacking smart contracts
- Exploring alternative standards like ORC-20 (removing four-character name limitation) and SRC-20 (using different data storage methods)
Developers are rapidly innovating in this space, with further token design evolution expected.
