F2Pool co-founder Wang Chun has expressed opposition to Bitcoin Improvement Proposals BIP-110 and BIP-54, likening their approach to the "bundling bills" tactic used by U.S. politicians. Wang argues that the issues these proposals aim to address—such as time deviation attacks, lengthy block verification, fake payment proofs, and duplicate transactions—are minor historical edge cases. He believes they do not justify the coordination costs, node upgrade workload, and community attention required for a soft fork. Wang emphasizes that Bitcoin has more significant vulnerabilities beyond these four issues and suggests that limited development resources should focus on more critical and impactful problems.
