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 dropped brc-20 in march 2023 and fees hit 12 dollars for basic transfers within weeks
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
Timur A. creative doesnt begin to cover it. inscribing JSON on satoshis to create tokens on a chain with no smart contracts was a hack that broke fees for everyone
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
paying 22 dollars to move 0.50 worth of btc on the ordinals protocol was the breaking point
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
utf8_warlock 28 sats per vByte to 12 dollar transfers in 6 weeks. the fee curve was basically vertical and people were still minting meme tokens on satoshis
domo tagged BRC-20 as experimental and people still minted 800M market cap in 60 days. the github readme literally had it in caps
12 dollar transactions on the chain that was supposed to be digital cash. BRC-20 was a fascinating experiment that priced out the exact users BTC was built for
Lightning was supposed to solve the fee problem and then BRC-20 made it worse by pushing everyone back to the base layer. deeply ironic
Sami N. lightning was already struggling with routing before BRC-20. the congestion just exposed how far bitcoin L2 still was from being usable for normal people
28455 btc price during the may 2023 congestion still did not stop the brc-20 mint rush
the fee market purge was honestly healthy long term. showed btc base layer cant host degens without pricing out actual users
ong_debug_ healthy is a stretch when a basic transfer cost 22 bucks. that just pushed everyone to lightning which nobody actually uses for payments either
all that energy spent inscribing JPEGs and meme tokens onto satoshis while Lightning Network adoption quietly stalled. priorities were backwards
Mette H. lightning adoption didnt stall because of ordinals, it stalled because routing liquidity is still a nightmare for non-technical users
i waited 9 blocks for a 50k sat transaction that normally confirms in 1. BRC-20 was fun for speculators but a disaster for anyone using BTC as actual money
BRC-20 was the moment bitcoin maxis learned what fee market competition feels like from the other side. suddenly inscriptions were fine but DeFi on ETH was a bug
mempool_mourner_ the irony is domo literally wrote EXPERIMENTAL in bold on the github and people still aped 8 figures into brc-20 tokens
Gints U. Domo put EXPERIMENTAL in caps and people still minted 800M in BRC-20 market cap within 60 days. the disclaimer was right there
Gints U. exactly, domo put EXPERIMENTAL in the readme and the market still assigned a billion dollar valuation to brc-20 tokens. reminds me of the ICO craze but on the chain that was supposed to be too dumb for tokens
