About block 953,568
Bitcoin block 953,568 was mined by F2Pool on June 14, 2026 at 12:23 AM UTC, 11 min 17 s after block 953,567. That is slower than the 10-minute target; long gaps are normal, since every hash attempt is an independent draw with the same tiny chance.
It confirmed 4,878 transactions in 1.61 MB (99.9% of the 4 million weight-unit limit). The median transaction paid 1.00 sat/vB, up from 1.00 sat/vB in the block before, and all fees added up to 0.0230 BTC. With the 3.125 BTC subsidy of halving era 5, F2Pool earned 3.1480 BTC for this block.
Block 953,568 is number 1 of 2,016 in difficulty epoch 473; 2,015 blocks remain until the next difficulty adjustment at block 955,583. The next halving is at block 1,050,000, 96,432 blocks after this one.
Its hash starts with 20 zeros: that is the proof of work, a number below the target that the whole network’s hashrate had to search for. F2Pool found 170 blocks in the week before. Today the block has 21,797 confirmations, so it is settled beyond any practical doubt.
Why block 953,568 is notable
Block 953,568 opens difficulty epoch 473. Every 2,016 blocks, each node recalculates the mining difficulty from how long the previous epoch took: if those blocks arrived in less than two weeks, difficulty goes up; if they took longer, it goes down, never by more than a factor of four. The new value, 124,932,866,006,548, took effect with this block, found by F2Pool on June 14, 2026 at 12:23 AM UTC, and applies until block 955,583; the following adjustment is at block 955,584.
Nobody schedules a retarget. It happens when the chain reaches the height, so the adjustment at block 953,568 came the moment F2Pool found it, not on a fixed date. The rule keeps the average close to one block every ten minutes however much hashrate joins or leaves the network.
Of the 3.14803996 BTC that F2Pool collected for this block, 3.125 BTC was new subsidy and 0.02303996 BTC came from fees, 0.7% of the total; leaving out the coinbase, its 4,877 transactions paid about 472 sats each on average.

What’s inside a Bitcoin block
Every block, 953,568 included, is made of the same parts:
- Header
- Eighty bytes that miners hash over and over: the version, the hash of the previous block, the Merkle root that summarises every transaction, a timestamp, the difficulty target in compact form and a nonce. A block is valid when the hash of its header falls below the target.
- Coinbase transaction
- The first transaction, written by the miner. It spends no inputs: it creates the subsidy and collects the fees, and since BIP 34 it must also record the block height.
- Transactions
- Everything else in the block: payments taken from the mempool, usually picked by fee rate because space is capped at 4 million weight units. Block 953,568 holds 4,878, counting the coinbase.
- Fees
- The difference between what each transaction spends and what it creates. The miner claims them in the coinbase; they are the part of the reward set by demand rather than by the protocol.
- Subsidy
- New bitcoin created by the block, fixed by the halving schedule: 50 BTC at the start, halved every 210,000 blocks. At height 953,568 it is 3.125 BTC.
