Ripple CTO emeritus David Schwartz criticized BIP-110 supporter Loogart's description of the BLAKE2b project as an effort to fix Bitcoin's legacy chain. The exchange began after an X user called BLAKE2b an attack on BTC and compared it with earlier Bitcoin Cash and Bitcoin SV forks. BLAKE2b is a breakaway Bitcoin hard fork backed by developer Luke Dashjr that replaces Bitcoin's SHA-256d mining algorithm and is set to launch on September 1. Loogart argued that participants were pursuing a separate chain voluntarily after opposing Bitcoin Core's direction. Schwartz replied that the project shifted from governance participation to attacking after its supporters refused to accept losing. He later highlighted the phrase fix the legacy chain with the response, Listen to yourself. The dispute comes as Bitcoin Knots attempts a second breakaway chain after BIP-110 stalled with only two blocks. The new chain uses BLAKE2b proof-of-work to avoid relying on existing Bitcoin miners, but no major exchange, wallet or Lightning implementation has committed to supporting it. BIP-110 proposed temporarily restricting Bitcoin block space used for non-financial data from Ordinals, BRC-20 and Runes, while its minority chain mined two blocks in eight hours before effectively stalling earlier in August.
