A rare two-block reorganization occurred on the Bitcoin network, with Foundry USA winning the block battle.

PANews reported on March 24th that, according to U.Today, the Bitcoin network experienced a rare two-block reorganization last night. At height 941880, the network briefly split into two competing chains. AntPool mined block 941881, and ViaBTC subsequently mined block 941882 on the same chain; simultaneously, Foundry USA mined its version of block 941881 and continued mining its version of block 941882. After Foundry USA continued mining blocks 941883, 941884, and 941885, the competing chains were broken, and the blocks from AntPool and ViaBTC were discarded as orphan blocks.

This reorganization was not an attack or malfunction, but rather a normal result of the decentralized consensus mechanism of Bitcoin. Single-block reorganizations are common, but two-block reorganizations are relatively rare, meaning that the tie between the two chains lasted for an entire block cycle. Foundry USA mined seven consecutive blocks from 941879 to 941885.
