🎓 Explain Like I'm 10

Bitcoin mining is a giant lottery. Every ~10 minutes, one miner wins 3.1418 Bitcoin — worth $241,978 today.


On Oct 30, 2026, this miner using mining hardware found block #973,821. They were mining alone — no big pool, just their own machines competing directly against the entire Bitcoin network (1071.56 EH/s total).


Winning solo means keeping 100% of the reward — no pool fees, no sharing. High risk, high reward.

Avg Gap
How we estimate: Each Bitcoin block found requires approximately difficulty × 2³² hashes. With 8 blocks over 7 days, the implied sustained hashrate is 6.45 EH/s.
⚠️ Not a solo miner. At 6.45 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 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 538,010,164 was the winner.

💡 The miner also tried different extra nonce values — restarting from 0 each time the full 4.29B range was exhausted. A modern ~200 TH/s ASIC runs through all 4.29 billion nonces in about 0.02 ms — some 47,000 times every second.
💸 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.

🔍 How We Know This
⛓️
Block is on the Bitcoin blockchain
The block hash starts with many zeros — proof of work that cannot be faked. It's in Bitcoin's immutable history forever.
🏷️
Pool identified from coinbase tag
The coinbase transaction contains a text signature: "^

Hashrate from Estimated from block frequency (8 blocks found)
We query the pool's public API using the miner's wallet address to get their actual submitted hashrate.
❓ What is Solo Mining?

In pool mining, thousands of miners work together and split the reward every time they find a block.


In solo mining, you work alone. You keep 100% of the reward — but you might go years without finding anything.


The Bitcoin network produces ~52,560 blocks per year. Each block currently pays 3.125 BTC.


Every solo block is proof that small miners can still win. 🎉
