The misleading news double-spend attack first became news and a trending topic on Twitter after BitMex Research reported on block 666,833’s misleading information on Twitter. The reorganization meant a “stale block” (also sometimes called an “orphan block”) had been mined that contained bitcoin also spent on Bitcoin’s valid blockchain, so a transaction containing the same bitcoin was recorded on both the relevant and irrelevant chains.

What BitMEX research called at first a “double-spend-like scenario” now looks like a brilliant storm caused by the one block reorg and a replace-by-fee transaction. A RBF transaction occurs when you tell your wallet to send the same bitcoin again but with a higher fee, with the hopes that it will be confirmed before the lower fee transaction.
