CKPool Solo Miner With 70 TH/s Wins $222,000 Bitcoin Block

The outlier win shows how proof-of-work still gives small miners a shot at a full payout.

Overview

  • The solo miner, whose block 944,306 was confirmed Thursday by CKPool and mempool explorers, earned 3.128 BTC worth about $222,000.
  • CKPool’s Con Kolivas said the miner ran roughly 70 terahashes per second, a sliver of a network near 1.02 zettahashes per second.
  • Pseudonymous CKPool developer Dr-ck put the chance at about 1 in 100,000 per day for a miner of that size.
  • CKPool lets users mine in a solo setup and keeps a 2% fee when a block is found, with this win counted as the service’s 313th solo block.
  • The score follows another CKPool solo find days earlier at block 943,411 for roughly $210,000, underscoring rare lottery-like wins in a pool-dominated mining scene.
