A short-lived fork appeared on the Bitcoin network on March 24 after Antpool mined block 941,881 at 15:49:35 UTC and Foundry USA produced a different version of the block 12 seconds later. The split briefly left two competing chains at the same height. ViaBTC then extended the Antpool version with block 941,882, while Foundry USA kept building on its own branch. Foundry USA went on to mine blocks 941,883 through 941,886 in succession, giving its branch the lead in cumulative work. Nodes later reorganized to the Foundry USA chain, which became the winning version of the ledger. As a result, blocks mined by Antpool and ViaBTC on the losing branch were orphaned. The miners involved lost the associated block rewards and transaction fees. Transactions that were not confirmed on the winning chain returned to the mempool and were later confirmed in subsequent blocks.
