Bitcoin News said in a post on X that Dathon Pwn claims to have identified a late-upgrade consensus flaw tied to BIP 110. According to the claim, nodes upgraded from older software could retain chain history that newly deployed BIP 110 nodes would reject. That mismatch, if confirmed, could create a hidden chain split. The post did not provide additional technical detail beyond describing the difference in how upgraded legacy nodes and newly deployed BIP 110 nodes may treat historical chain data. The claim was relayed by Bitcoin News on X and cited by ChainCatcher in a market analysis newsflash. No further information was included in the source text.
