Blockstream CEO warns BIP-110 has technical flaws, risks contentious fork

Blockstream CEO Adam Back rejected Bitcoin Improvement Proposal (BIP) 110 on June 8, stating it has technical flaws. He warned that forcibly activating the proposal without broad ecosystem support could trigger a contentious fork, splitting Bitcoin into minority chains. The proposal, BIP-110, seeks to limit non-financial data in Bitcoin transactions. Proponents are pushing to implement it via a User Activated Soft Fork (UASF) without miner consensus, with the debate intensifying in early June. Michael Saylor has also described BIP-110 as a threat to the protocol and Bitcoin's greatest risk of self-inflicted harm. Back dismissed the proposal, arguing it is fundamentally different from SegWit, which previously gained widespread support, and asserted that its purported spam-reduction benefits would not be effective.
