🎓 Explain Like I'm 10
Bitcoin mining is a giant lottery. Every ~10 minutes, one miner wins 3.1503 Bitcoin — worth $240,781 today.
On Oct 13, 2025, this miner using mining hardware found block #918,887. They were mining alone — no big pool, just their own machines competing directly against the entire Bitcoin network (973.07 EH/s total).
Winning solo means keeping 100% of the reward — no pool fees, no sharing. High risk, high reward.
⚠️ Miner Identity Assessment
🏭
🏭 Large Unknown Pool
Based on 19 blocks found from this address
2.15 EH/s
Implied Hashrate
How we estimate: Each Bitcoin block found requires approximately difficulty × 2³² hashes.
With 19 blocks over 54 days,
the implied sustained hashrate is 2.15 EH/s.
⚠️ Not a solo miner. At 2.15 EH/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.
🎲 The Odds — Show Your Work
Hashrate unknown for this miner — odds cannot be calculated. They found a single block; their true hashrate is a mystery.

🎯 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 544,962,868 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 ~4294967.3ms.
💸 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 (99.2%)
Fixed reward, halves every 4 years
Fees — 0.025259 BTC (0.8%)
From 2,918 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.
