A dispute emerged over how to describe a stalled Bitcoin fork after Bitcoin Knots said the network was under attack when the BIP-110 branch stopped at block 961,633. David Schwartz, identified as XRP Ledger architect, pushed back on that framing as misleading. The episode centered on the BIP-110 branch, which had split from Bitcoin's main chain, and raised a familiar debate in crypto over whether failures on an alternative chain represent a direct threat to the primary network or simply problems within a separate fork.
