The post Bitcoin Logs Rare Two-Block Reorg as Mining Pools Clash—Network Shrugs It Off – Crypto News Bitcoin News appeared on BitcoinEthereumNews.com.

Foundry USA Extends Lead in Bitcoin Reorg Race The event unfolded around block height 941880 on March 23, when competing blocks were mined nearly simultaneously, creating a temporary fork between chains led by the mining pool giant Foundry USA and a rival branch backed by Antpool and Viabtc. Bitcoin developer and “observer” b10c discovered the reorg. “We just had a rare-ish two block fork/reorg between Foundry and AntPool+ViaBTC. Foundry mined six blocks in a row,” the developer wrote. “*seven, Foundry mined seven blocks in a row,” the X account b10c added. Within seconds, both sides extended their versions of the chain, producing two parallel branches of equal length. For a short window, different nodes recognized different chains as valid, a standard outcome when blocks are discovered at nearly the same time. The tie did not last long. Foundry USA pulled ahead by mining additional consecutive blocks, ultimately extending its chain beyond the competing branch. Once it established the longer chain, the network followed suit, abandoning the shorter version. The rival blocks mined by Antpool and Viabtc were marked as “orphaned,” meaning they were removed from Bitcoin’s canonical history. Transactions included in those blocks were not lost; they returned to the mempool and were later processed again. Analysts and onlookers, including Bitcoin observer b10c, described the episode as routine behavior under Bitcoin’s proof-of-work system. No exploit, double-spend, or malfunction was detected. If anything, the system did exactly what it is designed to do. Short reorganizations—especially single-block events—happen from time to time due to network latency and simultaneous discoveries. Two-block reorganizations are less common, but still well within expected parameters. The timing is notable. The reorg came shortly after a 7.76% downward difficulty adjustment, one of the largest declines this year. At the same time, global hashrate has slipped from prior highs,…
