David Schwartz criticized Bitcoin Knots over its characterization of a failed BIP-110 activation attempt, arguing the episode was being misrepresented as an attack on Bitcoin. The dispute followed a chain split at block 961,632, when Bitcoin Knots nodes enforcing BIP-110 diverged from the main Bitcoin chain after the proposal failed to activate as a soft fork (backward-compatible protocol change). Community context attached to the post said the main chain kept operating normally, while the minority BIP-110 branch fell far behind because it attracted little miner support. At one point, the main network had reached block 961,681 while a BIP-110-enforcing node was still at block 961,633, with blocks on that branch reportedly arriving several hours apart instead of Bitcoin's usual roughly 10 minutes. Bitcoin Knots nevertheless urged users to upgrade to its latest version, said it was working on a mitigation strategy to repair affected chain states, and announced plans to choose a new proof-of-work algorithm (method used to secure mining) through a deterministic random process.
