Foundry USA continuously mined 6 blocks, Bitcoin block 941,881 chain reorganization completed

Antpool mined Bitcoin block 941,881 at 15:49:35 UTC, and Foundry USA mined another version at the same height 12 seconds later, leading to a brief formation of two competing chains on the Bitcoin blockchain.

Subsequently, ViaBTC extended block 941,882 on the Antpool version, and Foundry USA continued to extend its own branch. Foundry USA then consecutively mined blocks 941,883 to 941,886, with its branch accumulating more work. Nodes then reorganized to the Foundry USA version, and the blocks mined by Antpool and ViaBTC were orphaned. Relevant miners lost the corresponding block rewards and transaction fees, and transactions not confirmed on the winning chain re-entered the memory pool and were confirmed in subsequent blocks.
