🔍 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: 4i\QdN_9ckpool/solo.ckpool.org/
Hashrate unknown
This pool doesn't expose per-miner API data. We can't verify the exact hashrate — only that they found the block.
❓ 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. 🎉
