The fork, which occurred on Saturday at block 961,632, inherited Bitcoin's mining difficulty but operates with a tiny share of hashpower. This has resulted in blocks being hours apart, with the chain needing 350 days to complete the 2,016 blocks required for a difficulty adjustment. Only 2.53% of blocks signaled for BIP-110, far below the 55% needed for activation without a split. Both the main Bitcoin chain and the BIP-110 chain still accept identical transactions, raising concerns about a novel attack method where transactions on the fork could be replayed on the main chain.
