🎓 Explain Like I'm 10

Bitcoin mining is a giant lottery. Every ~10 minutes, one miner wins 3.1392 Bitcoin — worth $260,641 today.


On Oct 16, 2026, this miner using mining hardware found block #971,781. They were mining alone — no big pool, just their own machines competing directly against the entire Bitcoin network (1021.75 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 186 blocks over 185 days, the implied sustained hashrate is 8.57 EH/s.
⚠️ Not a solo miner. At 8.57 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.

💡 Slow block — the network took longer than average. This miner kept hashing through a tough stretch. Luck > 100% means a faster-than-expected find.
🔍 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: /trustpool/,mm66-)n|AQtsu6sH#
📡
Hashrate from Estimated from block frequency (186 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. 🎉
