🎓 Explain Like I'm 10
Bitcoin mining is a giant lottery. Every ~10 minutes, one miner wins 3.1513 Bitcoin — worth $267,860 today.
On Nov 4, 2025, this miner using a Large mining farm found block #922,216. They were mining alone — no big pool, just their own machines competing directly against the entire Bitcoin network (974.27 EH/s total).
Winning solo means keeping 100% of the reward — no pool fees, no sharing. High risk, high reward.
⚠️ Miner Identity Assessment
🏭
🏗 Medium Pool
Based on 28 blocks found from this address
971.2 PH/s
Implied Hashrate
How we estimate: Each Bitcoin block found requires approximately difficulty × 2³² hashes.
With 28 blocks over 216 days,
the implied sustained hashrate is 971.2 PH/s.
⚠️ Not a solo miner. At 971.2 PH/s this is a large mining operation — likely an unregistered pool or industrial farm that mempool.space doesn't yet have a signature for. We display the block for completeness but mark it accordingly.

Probability per block = miner_hashrate / network_hashrate
= 308 PH/s / 974.27 EH/s
= 1 in 3,164
Expected wait = blocks_to_win × 10 minutes
= 3,164 × 10 min = 22 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 3,904,403,858 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 (99.17%)
Fixed reward, halves every 4 years
Fees — 0.026299 BTC (0.83%)
From 3,270 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.
