The fork, which split off on Saturday due to a proposal (BIP-110) to restrict non-payment data in transactions, has only produced two blocks since the split. In the same period, the main Bitcoin chain has produced over 300 blocks. The slow block production means the fork's network difficulty adjustment, which typically occurs every 2,016 blocks, is now projected to take 6.3 years to complete, up from 350 days on Sunday. This is because the mining difficulty inherited from the main chain remains high, while the fork's coin has no market value or buyers.
