If you tried sending a Bitcoin transaction in early May 2023, you probably noticed something unusual: the fees were significantly higher than normal, and transactions were taking much longer to confirm. The culprit was a phenomenon that had been building for weeks—the explosive growth of BRC-20 tokens on the Bitcoin network. With Bitcoin trading at $28,455 and the total market cap exceeding $550 billion, understanding what BRC-20 tokens are and why they were causing network congestion became essential knowledge for anyone involved in cryptocurrency.
The Basics
BRC-20 is an experimental token standard created in March 2023 by an anonymous developer known as Domo. Unlike Ethereum’s ERC-20 standard, which uses smart contracts to manage tokens, BRC-20 tokens are created using Bitcoin’s Ordinals protocol—a system that allows data to be inscribed directly onto individual satoshis (the smallest unit of Bitcoin).
Think of it this way: if Bitcoin is like a ledger book, Ordinals allows you to write notes in the margins of individual pages. BRC-20 uses those margin notes to create and transfer tokens. It is an ingenious hack, but it comes with significant trade-offs—primarily because Bitcoin was never designed to handle this type of token activity.
The most popular BRC-20 tokens in early May 2023 included ORDI, the first token created using the standard, as well as numerous memecoins inspired by the success of PEPE on Ethereum. The total market capitalization of BRC-20 tokens had surged past $1 billion, creating a gold rush mentality that flooded the Bitcoin network with inscription transactions.
Why It Matters
The BRC-20 token frenzy directly impacted everyday Bitcoin users in several ways. First and most obviously, transaction fees skyrocketed. Average Bitcoin transaction fees reached levels not seen in years, with some users reporting fees of $30 or more for a simple transfer. For users in developing countries who rely on Bitcoin for remittances and everyday transactions, these fees were prohibitively expensive.
Second, transaction confirmation times increased dramatically. The Bitcoin network processes approximately seven transactions per second under normal conditions. The flood of BRC-20 inscription transactions consumed a disproportionate share of block space, pushing regular transactions into a growing mempool backlog.
Third, the congestion highlighted a fundamental tension in Bitcoin’s design philosophy. Bitcoin was created as peer-to-peer electronic cash, a system optimized for financial transactions. BRC-20 tokens repurposed Bitcoin’s security model for speculative token creation, raising questions about the network’s intended purpose and the sustainability of its limited block space.
Getting Started Guide
If you want to understand BRC-20 tokens and their impact, here is a practical guide to navigating this new landscape. First, familiarize yourself with the Ordinals protocol. Ordinals assign a unique number to each satoshi based on the order in which it was mined. This numbering system allows individual satoshis to be tracked and inscribed with data, including BRC-20 token information.
Second, understand how BRC-20 token operations work. There are three primary operations: deploy (create a new token), mint (create tokens according to the deployment parameters), and transfer (move tokens to another address). Each operation requires a Bitcoin transaction, which is why the standard generates so much network activity.
Third, if you want to interact with BRC-20 tokens, you will need a compatible wallet. Several wallets emerged in early 2023 to support Ordinals and BRC-20, including UniSat and the Ordinals Wallet. These wallets manage the inscription process and help users track their BRC-20 holdings.
Fourth, be prepared for higher fees. When BRC-20 activity is high, even simple token operations can cost significantly more than the base Bitcoin transaction fee. Monitor the mempool using tools like mempool.space to gauge current network conditions before transacting.
Common Pitfalls
New BRC-20 users should be aware of several common mistakes. The most dangerous is confusing BRC-20 tokens with actual Bitcoin. BRC-20 tokens are separate assets that happen to exist on the Bitcoin blockchain. They do not benefit from Bitcoin’s monetary properties or its established market value.
Another pitfall is attempting to send BRC-20 tokens using a regular Bitcoin wallet. If you send an inscribed satoshi to a wallet that does not support Ordinals, you may lose access to your tokens permanently. Always use a compatible wallet that recognizes inscription data.
Users should also be cautious about the speculative nature of many BRC-20 tokens. Unlike Bitcoin, which has a proven track record spanning over a decade, most BRC-20 tokens are experimental and highly volatile. The memecoin dynamics that drove much of the BRC-20 hype in May 2023 meant that many tokens could lose most of their value within days or even hours.
Finally, do not underestimate the technical complexity. BRC-20 is explicitly labeled as an experimental standard. The tooling is immature, the documentation is limited, and the standard itself may undergo significant changes. Only engage with BRC-20 if you are comfortable with these risks.
Next Steps
The BRC-20 phenomenon is likely just the beginning of tokenization on Bitcoin. As the ecosystem matures, expect to see more sophisticated token standards, improved tooling, and potentially Layer 2 solutions that alleviate network congestion. In the meantime, everyday Bitcoin users should monitor network conditions, adjust their fee expectations accordingly, and consider using the Lightning Network for smaller transactions when on-chain fees are elevated. Understanding BRC-20 is not just about participating in a new token trend—it is about understanding the evolving capabilities and limitations of the Bitcoin network itself.

Domo created BRC-20 as an experiment and it broke Bitcoin fees for weeks. unintended consequences at their finest
domo literally tagged it experiment in the github readme. people just ignored that part and aped in anyway. classic crypto behavior
literally tagged experimental and people still threw millions at it. the disclaimers were right there in the readme
inscribing token data onto satoshis is genuinely creative but the fee externality on regular users was brutal
paid $12 for a simple transfer that week. thanks ordinals lol
12 dollars for a simple transfer was the mild end. some people reported 30 plus for priority confirmation. regular users got priced out for weeks because of token experiments on satoshis
i paid 22 for a basic transfer that normally costs 0.50. regular users should not subsidize token experiments on the base layer
Boris T. i paid 28 sats/vB for a transaction that confirmed in 3 blocks the week before BRC-20 exploded. by May it was unusable for normal payments
all that energy spent inscribing JPEGs and meme tokens onto satoshis while Lightning Network adoption quietly stalled. priorities were backwards
