On Friday, November 21, 2025, a solo miner known as Solo CK successfully mined a Bitcoin block—despite contributing just 6 TH/s (terahashes per second) to a network-wide hashrate of 855.7 EH/s (exahashes per second).

The odds? A staggering 1 in 180 million per day—comparable to winning multiple lotteries simultaneously. The reward: 3.146 BTC plus transaction fees, worth nearly US$265,000 at current prices.

The miner used CKpool, an anonymous solo-mining pool launched in 2014, where individuals keep the full block reward (minus a 2% fee) if they solve a block—without sharing with large mining pools.

This marks the 308th solo block mined via CKpool—and Solo CK’s first in roughly three months. For context, in 2022, a solo miner with 126 TH/s (21× more power) faced odds of just 1 in 1.3 million. That means this recent feat is statistically rarer, especially given today’s mining landscape dominated by industrial-scale operations.

VECS Commentary

This isn’t just luck—it’s a living testament that Bitcoin’s decentralization is still breathing. Amid extreme hashrate concentration by ASIC farms and corporations, a home-scale miner’s success proves that proof-of-work remains mathematically fair: every single hash has an equal chance.

What’s poignant:

This isn’t a staged narrative—it’s the result of persistence, patience, and belief in the ethos of “run your own node, mine your own blocks.” Yet reality is stark: solo mining is now nearly impossible without extraordinary luck—not because the system is broken, but because past decentralization success has ironically attracted present centralization. Bitcoin doesn’t promise ease. It promises fairness—even if that fairness arrives once in 180 million tries.
