On Saturday, nodes enforcing the BIP-110 rules diverged from Bitcoin’s primary blockchain at height 961,632. Once the mandatory signaling window opened, enforcing nodes (primarily those running Bitcoin Knots) rejected non-compliant blocks and isolated themselves. In the hours after the split the minority chain generated only two blocks and stalled near height 961,633, while the main chain advanced dozens of blocks further. Because the breakaway chain inherited the prevailing high difficulty yet commands negligible hashrate, new blocks arrive only at long intervals. Bitcoin’s main chain, backed by the overwhelming majority of hashrate, has continued operating without interruption.
