TechFlow News, April 4: Wang Chun, co-founder of F2Pool, posted on X stating that Bitcoin protocol upgrades should not adopt the U.S. politicians’ practice of “bundling bills” to force through changes—a key reason he opposes BIP-110 and BIP-54. Several issues under discussion lack real urgency: for instance, the “timewarp attack” has existed for a long time but offers no tangible benefit to miners; block validation efficiency has already improved significantly due to libsecp256k1 and hardware upgrades, eliminating the need for protocol-layer adjustments; and “forging confirmed transactions” fundamentally relies on breaking SHA-256 collision resistance—its feasibility would imply Bitcoin’s core security has already been compromised. Wang Chun added that none of the above issues justify protocol modifications; currently, only the “duplicate transactions” issue holds some merit for remediation and may be among the few changes worth implementing.
