🎓 Explain Like I'm 10
Bitcoin mining is a giant lottery. Every ~10 minutes, one miner wins 3.1868 Bitcoin — worth $215,364 today.
On Jan 31, 2025, this miner using a Large mining farm found block #881,676. They were mining alone — no big pool, just their own machines competing directly against the entire Bitcoin network (1020.75 EH/s total).
Winning solo means keeping 100% of the reward — no pool fees, no sharing. High risk, high reward.

Expected blocks to find 1 solo block
10,844 blocks
Probability per block = miner_hashrate / network_hashrate
= 94.1 PH/s / 1020.75 EH/s
= 1 in 10,844
Expected wait = blocks_to_win × 10 minutes
= 10,844 × 10 min = 2.5 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 543,365,475 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 (98.06%)
