🎓 Explain Like I'm 10
Bitcoin mining is a giant lottery. Every ~10 minutes, one miner wins 12.7870 Bitcoin — worth $864,144 today.
On Dec 28, 2016, this miner using a Large mining farm found block #445,453. 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.

Probability per block = miner_hashrate / network_hashrate
= 13.1 PH/s / 1020.75 EH/s
= 1 in 78,011
Expected wait = blocks_to_win × 10 minutes
= 78,011 × 10 min = 1.5 years

🎯 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 1,609,755,089 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 — 12.5000 BTC (97.76%)
Fixed reward, halves every 4 years
Fees — 0.286977 BTC (2.24%)
From 888 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.
