A solo Bitcoin miner has achieved a rare success by validating a Bitcoin block using rented hashrate, earning a reward of over $200,000. The miner secured the 3.125 BTC block reward after successfully mining block 938092, utilizing $75 worth of on-demand hashrate. This approach allowed the miner to rent 1 petahash per second of computing power through CKPool, a service that enables individual miners to operate independently while using a pool server. Solo Bitcoin mining victories are uncommon, with only 21 miners achieving this feat in the past year, collectively earning 66 BTC, valued at $4.1 million. The occurrence of solo block mining has increased by 17% over the past year, with an average interval of 17.2 days between solo block discoveries. This development comes as the Bitcoin mining industry recovers from recent US winter storms, which had previously caused a significant drop in hashrate.
