Solo bitcoin miner overcomes 1-in-28,000 odds to secure $210,000 block reward

The win landed the same week listed miners Riot, MARA, and Genius Group disclosed selling more than 19,000 BTC from their treasuries.

What to know:

• A solo bitcoin miner with roughly 230 terahashes per second of computing power unexpectedly validated block 943,411, earning 3.139 BTC worth about $210,000.
• The miner, connected to the anonymous solo.ckpool.org pool and representing just 0.00002% of the network's estimated 1-zetahash hashrate, faced roughly 1-in-28,000 odds of finding a block on any given day.
• The win is part of a recent streak of improbable solo-mining successes on CKpool, including small-scale miners beating odds as steep as 1-in-180-million to secure six-figure rewards.

A solo bitcoin miner running roughly 230 terahashes per second of computing power validated block 943,411 on Thursday, pocketing 3.139 BTC worth about $210,000 despite controlling a share of total network hashrate so small it rounds to zero on most dashboards.

The miner was connected to solo.ckpool.org, the anonymous solo mining pool introduced in 2014 that lets operators keep their full block rewards minus a 2% fee. CKpool developer Con Kolivas confirmed the win on X, noting the miner had roughly a 1-in-28,000 chance of finding a block on any given day.

At 230 terahashes, the winning rig represents about 0.00002% of bitcoin's total estimated hashrate of roughly 1 zetahash per second as of early April. That output is consistent with a small stack of home-scale ASICs running under a single roof rather than a rented cloud burst or industrial operation.

For context, listed miner Riot Platforms alone runs more than 30 exahashes, roughly 130,000 times the hashrate of Thursday's winner.

The block is the 312th solo win registered on CKpool since its inception, and the first since Feb. 28, ending a 33-day drought. Solo pools have found just 20 bitcoin blocks over the past 12 months, distributing a combined 62.96 BTC. That's roughly one solo block every 18.7 days on average, with a longest gap of 58 days.

The win continues a pattern that has repeated with surprising regularity through this cycle.

In December, a roughly 270 TH/s miner cleared 1-in-30,000 daily odds to claim a $284,633 reward. In November, a miner running just 6 TH/s, the output of a single old-generation ASIC that would not normally expect to find a block in hundreds of years of continuous mining, beat 1-in-180-million odds to land roughly $265,000.

And in late February, a miner turned approximately $75 of rented cloud hashrate into a $200,000 reward by pointing just 1 petahash at CKpool for a few hours.

Most crypto privacy models weaken as blockchain data grows. Encryption-based models like Zcash strengthen. CoinDesk Research maps the five privacy approaches and examines the widening gap.

Why it matters:

As blockchain adoption scales, the metadata available to machine learning models scales with it. Obfuscation-based privacy approaches are structurally degrading as a result. This report provides a comprehensive comparison of all five major crypto privacy architectures and a framework for evaluating which models remain durable as AI capabilities improve.
