Bitcoin miners had plenty to celebrate in May 2023. A wave of BRC-20 token inscriptions and Ordinals activity drove transaction fees to five-year highs, generating approximately $63.2 million in fee revenue for miners during the month alone — surpassing the combined fee income from the entire first four months of the year.
TL;DR
- Bitcoin miners collected 2,750 BTC ($63.2 million) in transaction fees during May 2023
- Fee revenue in May exceeded the combined total of January through April (2,233 BTC / $69.3 million)
- Transaction fees surpassed the 6.25 BTC block subsidy on May 7 for the first time since December 2017
- Hashprice hit $129 per petahash per day, a 72% jump from the prior week
- BitMart and UniSat announced a strategic partnership to advance BRC-20 token infrastructure
The BRC-20 Fee Explosion
The catalyst behind the fee surge was BRC-20, an experimental token standard that leverages Bitcoin’s Ordinals protocol to create and transfer fungible tokens directly on the Bitcoin blockchain. What began as a niche experiment in March 2023 exploded into a speculative mania by early May, with thousands of users competing to inscribe tokens onto the network.
The bidding wars for block space were so intense that on May 7, at block height 788,695, transaction fees exceeded the 6.25 BTC block subsidy for the first time in this halving epoch. Some blocks contained over 6.4 BTC in fees alone, pushing total block rewards above 12.5 BTC — a figure not seen since the previous halving era’s base subsidy. The average fee-to-block-subsidy ratio during the first full week of BRC-20 mania reached 33.09%, compared to just 6.37% the week prior and a paltry 1.9% in early November 2022.
For context, the highest fee-to-subsidy ratio ever recorded was 77% on December 22, 2017, during Bitcoin’s historic bull run. The May 2023 spike represented the second-highest reading in Bitcoin’s history, underscoring just how transformative the BRC-20 phenomenon was for network economics.
A Lifeline for Struggling Miners
The timing of the fee surge could not have been better for Bitcoin miners. Throughout 2022, mining profitability had deteriorated sharply as Bitcoin’s price declined from its November 2021 all-time high of $69,000 while network hashrate continued climbing. Daily mining revenue in USD terms bottomed below $10 million on Christmas Eve 2022.
The BRC-20 fee bonanza abruptly reversed that trajectory. Hashprice — the revenue miners earn per unit of computational power — spiked to $129 per petahash per day during the peak of the inscription frenzy, representing a 72% increase from the prior week. Daily Bitcoin-denominated revenue climbed back to levels last seen in May and June 2022, before the worst of the bear market took hold.
The average transaction count per block also hit an all-time high of 4,373 on May 7, as users flooded the network with inscription transactions. Year-to-date, the average daily transaction fee in BTC was 38.63 ($1.03 million), compared to 16.50 ($329,795) during the second half of 2022 — a dramatic shift that demonstrated how new use cases were fundamentally altering Bitcoin’s revenue model.
BitMart and UniSat Partner to Build BRC-20 Infrastructure
As BRC-20 tokens captured mainstream attention, the infrastructure needed to support them was racing to catch up. On May 29, 2023, cryptocurrency exchange BitMart and UniSat — the leading open-source Bitcoin wallet for Ordinals and BRC-20 — announced a strategic partnership aimed at strengthening the resilience, security, and interoperability of the BRC-20 ecosystem.
The collaboration represented a significant milestone for Bitcoin’s emerging DeFi capabilities. UniSat had established itself as the primary gateway for users interacting with BRC-20 tokens and Ordinals inscriptions, while BitMart brought exchange infrastructure and liquidity to the table. Together, the partnership signaled growing institutional recognition that Bitcoin’s utility was expanding beyond its traditional role as a store of value.
The partnership also addressed a critical gap in the BRC-20 ecosystem: the lack of robust trading and custody infrastructure. While anyone could inscribe tokens directly on-chain, the user experience for trading and managing BRC-20 holdings remained fragmented. By combining UniSat’s wallet technology with BitMart’s exchange capabilities, the two companies aimed to create a more seamless pipeline from inscription to trading.
Implications for Bitcoin’s Long-Term Security Budget
The fee spike reignited a long-running debate within the Bitcoin community about the network’s long-term security model. With block subsidies halving approximately every four years — the next halving was expected in April 2024 — miners would increasingly depend on transaction fees to sustain their operations. The BRC-20 episode demonstrated that fee markets could indeed generate substantial revenue when on-chain activity is sufficiently high.
Critics argued that speculative BRC-20 trading was not a sustainable source of fee revenue, and that the congestion it caused harmed ordinary Bitcoin users. Average transaction fees briefly exceeded $7 in early May, with some reports of fees peaking above $16. Supporters countered that any activity generating fee revenue was ultimately beneficial for network security, and that the market would naturally equilibrate as users prioritized transactions.
Why This Matters
May 2023 was a watershed moment for Bitcoin’s economic model. For the first time in years, transaction fees became a material contributor to miner revenue — not through a gradual evolutionary process, but through an explosive speculative wave that caught much of the industry off guard. The BitMart-UniSat partnership showed that serious infrastructure players were already positioning themselves for a Bitcoin DeFi ecosystem. Whether BRC-20 tokens represent a lasting paradigm shift or a transient speculative episode, the fee data from May 2023 provided a compelling proof-of-concept for Bitcoin’s fee-driven security future.

miners making more from fees than the 6.25 btc subsidy on may 7 was insane. first time since 2017. ordinals changed the game overnight
and people said ordinals were just a fad. 63 million in fee revenue for miners in one month. that is sustainable demand, not speculation
$63M in one month looks sustainable until you realize most of it was speculative inscription volume that disappeared by june
Tobias W. calling $63M sustainable demand is wild when BRC-20 volume was 90% meme token minting. The fee market didn’t mature — it caught a speculative wave and surfed it until the wave broke. Real sustainable fees come from Lightning routing, not JPEGs.
ordinals_skeptic calling BRC-20 fees speculative is correct but Lightning routing fees are also tiny. neither generates enough sustainable fee revenue to replace the block subsidy long term
lightning routing fees are still negligible compared to L1 fees during ordinals peaks. the sustainable fee model argument is unresolved either way
Tobias K. lightning routing fees being negligible is exactly the point. L2 was supposed to handle small tx volume but L1 ended up doing it through inscriptions instead
ordinals_skeptic BRC-20 being 90% meme minting doesnt change the fee floor being permanently higher. may 2023 proved bitcoin blockspace has demand at the right price
fee revenue exceeding the 6.25 BTC subsidy was the moment bitcoin mining economics fundamentally changed. sustainable fee market is what makes the long term security model work
fee market becoming sustainable is the thesis but that was may 2023. fee revenue collapsed when inscription hype cooled
Elif M. calling it collapsed is generous — June 2023 fee revenue dropped 70% from May peaks. But the infrastructure built during the spike (UniSat indexing, BitMart trading rails) didn’t disappear. The fee floor is permanently higher than pre-Ordinals.
hashprice jumping 72% to 129 per ph per day is why i am bullish on mining stocks. the brc-20 wave turned mining from a subsidy game into a fee business
bitmart and unisat partnering on brc-20 infrastructure is the real signal here. exchanges are building the rails, miners just collect
bitmart and unisat building rails while miners just collected fees. that分工 tells you who the long term winners from ordinals actually are
miners making 63M in fees from BRC-20 mania while core devs were actively complaining about ordinals. peak crypto moments
Tobias L. hashprice jumping to 129 per petahash in a week. BRC-20 basically subsidized the entire mining sector right before the halving narrative kicked in
transaction fees surpassing the 6.25 BTC block subsidy on May 7 was the real milestone. miners basically got a second income stream overnight
fees beating the 6.25 BTC subsidy even once was historic. people forget that was the first time since 2017 it happened without a mania top
Darius M. fees beating the 6.25 BTC subsidy happened once in may 2023 and never again at that level. calling it historic is fair, calling it a trend is cope
subsidy_math_ happening once and never again is still significant. it proved the fee market CAN exceed the subsidy under demand pressure. the security model works in theory
The 72% hashprice jump is the real story nobody digs into. Mining pools adjusted their payout algorithms overnight to capture fee revenue, and smaller miners got squeezed by updated FPPS calculations. The fee boom accelerated consolidation in mining pools — fewer independent operators now than before Ordinals.
pool_operator_ the FPPS squeeze was real. saw 3 small pools shut down within weeks of the fee spike because they couldnt retool their payout logic fast enough
pool_operator_ the FPPS squeeze on small miners during the fee spike was brutal. consolidation accelerated 18 months in 3 weeks
63M in fees in one month from JPEGs on Bitcoin. miners made more from BRC-20 than block subsidies. and people still say ordinals have no utility. they literally funded the security budget
fees surpassing the 6.25 BTC block subsidy on May 7 was the signal. miners were getting paid more to inscribe memes than to secure transactions. Satoshi rolling in his pseudonym
