🎓 Explain Like I'm 10
Someone spent a small amount of money to rent mining power from NiceHash for a short time. They pointed it at the Bitcoin network solo, hoping to win the lottery.
On Jul 13, 2025, against enormous odds, they hit the jackpot — block #905,331 worth $213,948. The cost of renting that hashrate? A fraction of the reward.

Miner's share of total Bitcoin hashrate
0.010741%
Miner: 109.6 PH/s vs Network: 1020.75 EH/s
Miner hashrate (Estimated from block frequency (3 blocks found))
109.6 PH/s
Bitcoin network hashrate
1020.75 EH/s
Chance of winning each block
1 in 9,310
Expected wait time at this hashrate
65 days
Expected blocks to find 1 solo block
9,310 blocks
Probability per block = miner_hashrate / network_hashrate
= 109.6 PH/s / 1020.75 EH/s
= 1 in 9,310
Expected wait = blocks_to_win × 10 minutes
= 9,310 × 10 min = 2.1 months

🎯 The Winning Number — Nonce Visualizer
To mine a block, the miner cycles through numbers from 0 to 4,294,967,295 at billions per second, checking if each produces a valid hash. Number 2,269,679,381 was the winner.

💡 The miner also tried different extra nonce values — restarting from 0 each time the full 4.29B range was exhausted. Modern ASICs can cycle through the entire nonce space in ~0ms.
💸 Fee Breakdown — What the Miner Captured
The block reward has two parts: a fixed subsidy set by Bitcoin protocol, plus transaction fees paid by users who wanted their transactions included.
Subsidy — 3.1250 BTC (98.71%)
Fixed reward, halves every 4 years
Fees — 0.040843 BTC (1.29%)
From 3,183 transactions in this block
⚡ Solo miners keep 100% of fees — no pool takes a cut. In pool mining, the fee revenue is also split among all pool members.
