🎓 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 Apr 8, 2025, against enormous odds, they hit the jackpot — block #891,426 worth $211,781. The cost of renting that hashrate? A fraction of the reward.

Expected blocks to find 1 solo block
3,538 blocks
Probability per block = miner_hashrate / network_hashrate
= 288.5 PH/s / 1020.75 EH/s
= 1 in 3,538
Expected wait = blocks_to_win × 10 minutes
= 3,538 × 10 min = 25 days

🎯 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 4,109,883,043 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 (99.72%)
Fixed reward, halves every 4 years
Fees — 0.008786 BTC (0.28%)
From 607 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.
