After days of unprecedented congestion that saw Bitcoin transaction fees skyrocket to $31 per transfer, the network is finally showing signs of relief. On May 11, 2023, average on-chain fees plummeted by more than 90% to just $3.00 for high-priority transactions, as the mempool backlog that had swelled to over 500,000 unconfirmed transactions began to steadily clear.
TL;DR
- Bitcoin mempool peaked at 500,000+ unconfirmed transactions on May 7, an all-time high
- By May 11, the backlog dropped to approximately 300,000 pending transactions
- Average transaction fees crashed from $31 (May 8) to $3.00 — a 90%+ decline
- BRC-20 token and Ordinals inscription frenzy was the primary cause of congestion
- Ordinals trading volume fell from $18.13 million (May 8 ATH) to $4.86 million by May 11
- Global hashrate remained steady at 342 EH/s with difficulty adjustment expected May 18
The BRC-20 Fever That Clogged Bitcoin
The root cause of the congestion crisis was a speculative mania around BRC-20 tokens — a new standard for creating fungible tokens on the Bitcoin blockchain using Ordinals inscriptions. What began as an experimental technology quickly morphed into a meme coin gold rush, with thousands of users racing to mint and trade BRC-20 tokens directly on Bitcoin’s base layer.
The result was predictable to anyone familiar with block size economics: demand for block space exploded, the mempool filled to historic levels, and transaction fees surged to levels not seen in years. On May 7, the queue of unconfirmed transactions breached 500,000 — an all-time record that brought back memories of the 2017 block size wars.
Relief Arrives as Speculation Cools
The turning point came as BRC-20 trading activity began to lose steam. Ordinals trading volume, which had hit an all-time high of $18.13 million on May 8, collapsed to $4.86 million by May 11 — a decline of more than 73%. The number of daily Ordinals transactions also dropped significantly, from approximately 17,000 to around 6,000.
UniSat, the dominant marketplace for BRC-20 tokens, saw its market share erode from 80-90% down to 50-60% as competing platforms emerged and user interest waned. The cooling demand meant fewer inscriptions competing for block space, allowing the mempool to begin draining naturally.
By 7:00 AM Eastern Time on May 11, the backlog had fallen to just over 300,000 unconfirmed transactions. While still elevated, the trajectory was clearly downward. Approximately 185 blocks still needed to be mined to fully clear the queue, but block times were running faster than the ten-minute target — averaging between 8 minutes 28 seconds and 9 minutes 57 seconds — accelerating the clearance process.
Fee Structure Normalizes
The fee relief was dramatic. After peaking at $31 per transaction on May 8, costs dropped precipitously:
- High-priority transactions: $3.00
- Medium-priority transactions: $2.65
- Low-priority transactions: $2.23
The more than 90% reduction in fees represented a return to normalcy for Bitcoin users who had been priced out of transacting during the peak of the BRC-20 frenzy. For context, many everyday Bitcoin users had been forced to either pay exorbitant fees or delay their transactions entirely during the congestion event.
Network Fundamentals Remain Strong
Despite the congestion drama, Bitcoin’s underlying infrastructure proved resilient. The global hashrate held steady at 342 exahash per second (EH/s), reflecting continued investment in mining infrastructure. Block difficulty was projected to increase by 0.1% to 1.94% at the next adjustment on May 18, a modest rise that suggests the network is adapting smoothly to current demand levels.
The congestion episode also reignited debate within the Bitcoin community about the appropriate use of block space. Critics argued that BRC-20 tokens and meme coin speculation represented a wasteful use of Bitcoin’s limited capacity, while proponents countered that the network’s ability to handle the surge — without any central coordination or intervention — demonstrated its robustness as a permissionless platform.
Why This Matters
The BRC-20 congestion crisis of early May 2023 was a stress test for Bitcoin at a scale the network had not experienced since the bull market peaks of previous cycles. The rapid escalation and equally rapid resolution offer several lessons. First, speculative manias can impose real costs on ordinary users — the $31 fee peak effectively shut out anyone not willing to pay premium prices for basic transactions. Second, market dynamics, not protocol changes, resolved the crisis: as fees rose, speculative activity declined, and the network cleared itself.
The episode also highlighted the growing tension between Bitcoin’s role as a store of value and its emerging use case as a platform for tokenized assets. As Ordinals and BRC-20 continue to evolve, the question of how Bitcoin should allocate its scarce block space will only become more pressing. For now, the network has passed this particular test — but the next wave of innovation (or speculation) could push it even harder.

500k unconfirmed tx in the mempool and fees at $31. then BRC-20 hype dies and fees crash to $3. classic speculative bubble playing out on the base layer
Hashrate steady at 342 EH/s through all of this. Miners just kept mining while the fee market went crazy and then normalized.
Johan K. 342 EH/s steady through the chaos tells you miners loved every second of $31 fees. the fee market was their dream scenario
342 EH/s holding steady while fees crashed 90pct just proves miners were extracting maximum value from the bubble. smart money exits first
watched the mempool chart like it was a horror movie for a week straight. 500k unconfirmed tx was genuinely scary
fee_panic 500k unconfirmed tx was genuinely terrifying if you had a time-sensitive transfer. watched my transaction sit for 4 days before RBF
fee_panic i was sending a tx at 28 sat/vB during the peak. watched it sit for 3 days before rbf. never again without rbf
Ordinals volume dropping 73% from $18M to $4.8M in 3 days. The BRC-20 bubble burst faster than most meme coin cycles.
73% volume drop in 3 days is faster than most meme coin cycles. the brc-20 crowd moved on to the next thing almost immediately
fee_panic same here. had a tx at 25 sat/vB stuck for 4 days. ended up using RBF twice. never going on-chain during a mania again
BRC-20 volume dropped 73% because the tokens themselves had zero utility. it was inscription gambling plain and simple
brc_skeptic inscription gambling is the perfect description. zero utility tokens clogging the base layer so people could mint jpgs on bitcoin
brc_skeptic exactly right. the tokens had no purpose beyond flipping. at least JPEGs on eth had communities behind them
Chen Wei 73% volume drop in 72 hours. faster than most memecoins dump. confirms it was pure speculation with zero sticky liquidity
500k unconfirmed transactions at peak and people were paying 31 per transfer for a BTC payment. BRC-20 was the most expensive L2 experiment that wasnt even an L2
Ordinals volume going from 18.13M ATH to 4.86M in three days. the crash was faster than the pump
^ 342 EH/s hashrate holding steady through the fee chaos shows miners did not care about BRC-20 either way. they just kept mining blocks
the fact that BRC-20 inscriptions are still happening at lower volume means the spam isnt going away. fees will spike again next cycle
Ordinals volume 18M to 4.8M in 3 days. faster crash than most ICO tokens in 2018. speculative mania with zero sticky demand
and this is why we need scaling. $31 fees even for a few days prices out everyone outside the developed world
layer2_please $31 fees for a week and the Lightning Network was sitting right there the whole time. people would rather pay 10x than use it
layer2_please 31 dollar fees for basic transfers prices out the entire global south. BTC as a payments network died during that week
lightning exists but nobody uses it for BRC-20 mints. the fee market exposed how fragile the base layer is when speculation overwhelms block space
brc_skeptic zero utility tokens clogging the base layer is exactly right. inscription gambling with no underlying product
BRC-20 fees crashing 90% in 3 days is the fastest speculative death spiral in BTC history. faster than ICOs, faster than NFTs
