🎓 Explain Like I'm 10

Someone spent a small amount of money to rent mining power from NiceHash for a short time. They pointed it at the Bitcoin network solo, hoping to win the lottery.


On May 19, 2025, against enormous odds, they hit the jackpot — block #897,427 worth $218,270. The cost of renting that hashrate? A fraction of the reward.

🔍 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: )SS/NiceHash/
📡
Hashrate from Estimated from block frequency (5 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. 🎉
