PANews posted on X (formerly Twitter) that the Bitcoin network underwent an unusual two-block reorganization last night. The event began at block height 941880, where the network briefly split into two competing chains. AntPool mined block 941881, followed by ViaBTC with block 941882. Meanwhile, Foundry USA mined its own versions of blocks 941881 and 941882, leading to a stalemate between the two chains.
Foundry USA continued to mine blocks 941883, 941884, and 941885, and according to the 'longest chain' principle, the blocks mined by AntPool and ViaBTC were eventually discarded, becoming orphan blocks. Foundry USA successfully completed a sequence of seven consecutive blocks from 941879 to 941885.
It is important to note that this reorganization was not due to an attack or network malfunction but rather a normal operation of Bitcoin's decentralized consensus mechanism. While single-block reorganizations occur occasionally, a two-block reorganization is rare, indicating that the tie between the two chains lasted for an entire block cycle.
