What to Know
- AntPool mined Bitcoin block 974,961 on Saturday with 11,255 transactions.
- The block was Bitcoin’s second-busiest by transaction count and came 984 transactions short of the 12,239-transaction record set by F2Pool in block 367,853 on Aug. 1, 2015.
- The transactions generated 240,533 satoshis in fees, worth about $180 at Sunday’s Bitcoin price near $75,800.
- Fees made up less than 0.1% of AntPool’s roughly $237,000 payout for the block.
- Nearly all of the miner payout came from Bitcoin’s fixed 3.125 BTC block subsidy.
- AntPool also mined block 974,557 on Nov. 4, carrying 10,573 transactions and paying about $110 in fees.
- Sampled transactions from the middle of Saturday’s block included 80-byte transactions paying a single satoshi and carrying a small data output.
- The median fee rate in Saturday’s block was rounded to zero by mempool.space.
- The subsidy is projected to halve in 2028, and Saturday’s fee haul would cover less than 0.2% of the subsidy miners stand to lose.
Bitcoin’s Second-Busiest Block Arrives With Barely Any Fee Revenue
Bitcoin produced one of its most transaction-heavy blocks on Saturday, but the fee revenue attached to it was strikingly small. AntPool mined block 974,961 with 11,255 transactions, making it the second-busiest block in Bitcoin history by transaction count. Despite that unusually high activity, the transactions together paid only 240,533 satoshis in fees, equal to about $180 at Sunday’s price near $75,800.
The block came close to a long-standing transaction-count record. F2Pool’s block 367,853, mined on Aug. 1, 2015, still holds the top spot with 12,239 transactions. AntPool’s Saturday block was only 984 transactions short of that mark, underscoring how dense Bitcoin blocks can become when transactions are small and fee rates are extremely low.
The fee figure stands out because it was tiny compared with the miner’s total reward. AntPool’s overall payout for the block was roughly $237,000, nearly all of which came from the fixed 3.125 BTC block subsidy minted by the Bitcoin protocol for the miner that finds a valid block. Fees accounted for less than 0.1% of that payout, a reminder that Bitcoin miners remain heavily reliant on subsidy revenue when fee pressure is muted.
Why the Fee Total Matters for Miners
Bitcoin miners earn revenue from two sources: the block subsidy and transaction fees. The subsidy is programmatic and fixed for each era of Bitcoin’s issuance schedule, while fees fluctuate based on demand for block space. When users compete aggressively to have transactions included quickly, fee revenue can rise. When block space is not under pressure, miners may include transactions that pay very little.
Saturday’s block illustrates the low-fee side of that system. Even with 11,255 transactions packed into a single block, the aggregate fee total remained below $200. That is not a sign that the block was empty or unused; rather, it shows that many of the included transactions were extremely small and carried minimal fees.
The issue is especially important because Bitcoin’s block subsidy is projected to halve in 2028. Under the current reward structure, miners receive 3.125 BTC before fees for finding a block. When the subsidy declines, fees become more important to the long-term economics of securing the network. Saturday’s fees would cover less than 0.2% of the subsidy miners stand to lose at the next halving, highlighting the scale of the gap between current low-fee blocks and the future revenue miners may need from transaction demand.
A Similar AntPool Block Appeared Days Earlier
The Saturday block was not an isolated occurrence. On Nov. 4, AntPool mined block 974,557, which carried 10,573 transactions and paid about $110 in fees. That earlier block also combined a high transaction count with very limited fee revenue, pointing to a broader pattern of compact transactions being included at negligible rates.
For market participants, the two AntPool blocks offer a fresh example of how Bitcoin’s fee market can behave during periods when users are not bidding aggressively for space. The network can process a large number of transactions in a block, but if those transactions consume little space and pay minimal rates, the resulting fee pool can remain small.
The contrast between transaction count and miner revenue is important. A high number of transactions does not automatically translate into high fees. Bitcoin fees are based on the space a transaction occupies, measured in virtual bytes, not simply the number of transfers inside a block. As a result, a block filled with many small transactions can generate less fee revenue than a block with fewer, larger, higher-priority transactions.
How Tiny Fees Reached the Block
Users bid for Bitcoin block space by attaching a fee rate per virtual byte. That rate determines how much a transaction pays relative to the amount of block space it consumes. In Saturday’s block, mempool.space rounded the median fee rate to zero, reflecting how low the typical included fee was.
A sample of transactions from the middle of the block showed a run of 80-byte transactions. Each paid a single satoshi and carried a small data output. A satoshi is one hundred-millionth of a bitcoin, making it the smallest unit commonly referenced in Bitcoin transactions. In this case, individual transactions paid the absolute minimum denomination while still being included in a valid block.
The rate associated with those transactions sat below the relay floor that Bitcoin Core 29.1 set by default last year, which was a tenth of a satoshi per virtual byte. That distinction matters because relay policy and consensus validity are not the same thing. A node’s default relay policy affects which transactions it forwards across the peer-to-peer network, but it does not necessarily determine whether a block is valid under Bitcoin’s consensus rules.
Blocks containing cheaper transactions can remain valid even if many nodes would not relay those transactions under default policy settings. Public data does not show how the transactions reached AntPool. They may have reached the miner through routes not visible in public mempool data, through direct submission, or through other pathways that do not require broad relay across the network. Any specific route remains unconfirmed from the public data available.
What It Says About Bitcoin’s Fee Market
The AntPool block adds to an ongoing discussion among miners, node operators, developers, and investors about Bitcoin’s long-term security budget. The network’s issuance schedule is designed to reduce the subsidy over time, which gradually shifts more responsibility to transaction fees if miner revenue is to remain robust in bitcoin terms.
Low-fee, high-transaction blocks do not by themselves prove that the fee market is broken. Bitcoin fees can vary widely depending on demand, mempool congestion, user urgency, and the type of activity taking place on the network. However, they do demonstrate that transaction count alone is an incomplete gauge of economic demand for block space.
For miners, the immediate incentive remains straightforward: include valid transactions when producing a block, collect the subsidy, and add whatever fees are available. In Saturday’s case, the subsidy did nearly all the economic work. The roughly $180 in fees was a tiny addition to the roughly $237,000 payout, making the block notable less for miner revenue than for the unusual combination of near-record transaction count and extremely low fee density.
For Bitcoin users, the block may be viewed as evidence that very low-cost transactions can still be mined under certain conditions. But it should not be interpreted as a guarantee that such conditions will persist. Fee markets can change quickly when demand rises, and users seeking timely confirmation may still need to bid competitively when block space becomes crowded.
Market Implications Remain Centered on Miner Economics
Bitcoin’s price near $75,800 on Sunday provided the conversion basis for the roughly $180 fee estimate, but the more significant takeaway for market participants is structural rather than short-term price-related. The episode highlights how dependent miners can be on the block subsidy during low-fee periods.
That dependence is manageable while the subsidy remains substantial, but each halving reduces the fixed reward. The projected 2028 halving is therefore a key reference point in the debate over whether future fee demand will be sufficient to replace a meaningful portion of subsidy income. Saturday’s block shows that, at least in this instance, fees were nowhere close to offsetting the subsidy reduction miners are expected to face.
Some chart watchers and mining-sector analysts are likely to focus on the contrast between network usage metrics and fee revenue. A block with 11,255 transactions might appear strong from a usage perspective, yet the economics for the miner were overwhelmingly driven by issuance. That distinction is central to evaluating Bitcoin’s long-term incentive structure.
For now, the network continued operating normally, the block was mined, and the transactions were included. The significance lies in what the block reveals about the current state of fee competition. Bitcoin can come close to a transaction-count record while delivering only a negligible fee contribution to miners, a dynamic that will remain important as the subsidy continues its scheduled decline.
Frequently Asked Questions (FAQs)
What happened in Bitcoin block 974,961?
AntPool mined Bitcoin block 974,961 on Saturday with 11,255 transactions, making it the second-busiest block in Bitcoin history by transaction count. Despite the heavy transaction load, the block generated only about $180 in fees.
How close was the block to Bitcoin’s transaction record?
The block was 984 transactions short of the record. The current record remains F2Pool’s block 367,853, which included 12,239 transactions on Aug. 1, 2015.
How much did AntPool earn from the block?
AntPool’s total payout was roughly $237,000. Nearly all of that came from Bitcoin’s fixed 3.125 BTC block subsidy, while transaction fees made up less than 0.1% of the payout.
Why were fees so low despite so many transactions?
Fees depend on block space used and fee rates paid per virtual byte, not simply the number of transactions. The block included many small transactions, and sampled transactions paid only a single satoshi each.
What is a satoshi?
A satoshi is one hundred-millionth of a bitcoin. The transactions in the sampled portion of Saturday’s block paid one satoshi each, which helped keep total fees extremely low.
Did another similar block happen recently?
Yes. On Nov. 4, AntPool mined block 974,557 with 10,573 transactions and about $110 in fees, showing a similar combination of high transaction count and very low fee revenue.
Why does this matter for Bitcoin miners?
Miners rely on both the block subsidy and transaction fees. Because the subsidy is projected to halve in 2028, low-fee blocks raise questions about how much future miner revenue can be supported by transaction fees when subsidy income declines.
Were the low-fee transactions invalid?
No. The fee rate sat below the default relay floor set by Bitcoin Core 29.1 last year, but relay policy is not the same as Bitcoin consensus rules. Blocks containing cheaper transactions can still be valid.
Does this mean Bitcoin fees will stay low?
Not necessarily. Bitcoin fees depend on demand for block space and can change quickly. Saturday’s block shows that very low-fee transactions can be included under certain conditions, but it does not guarantee that future transaction costs will remain low.
