F2Pool Co-Founder Wang Chun: Bitcoin Protocol Upgrades Should Not Use "Bundling Legislation" Approach, Oppose BIP-110 and BIP-54 Summary

F2Pool Co-Founder Wang Chun stated on the X platform that Bitcoin protocol upgrades should not resemble the "bundling legislation" approach used by American politicians, and he opposes BIP-110 and BIP-54. He mentioned that time warp attacks do not provide significant benefits to miners, and block verification efficiency has already been greatly improved. Currently, only the "replay transaction" issue is worth fixing.

According to Gate News, on April 4, Wang Chun posted on the X platform that Bitcoin protocol upgrades should not involve methods similar to the U.S. politicians' "bundling legislation" to push through "some necessary but unpopular clauses," which is a key reason for his opposition to BIP-110 and BIP-54. When asked whether he encountered issues with any fixes using BIP-54, Wang Chun added: The time warp attack problem has existed for a long time and does not offer significant advantages to miners because it cannot predict who will mine the next block. Its only practical use is to interfere with certain altcoins. Since it offers almost no real benefit to Bitcoin miners, there is no urgent need to modify it. Block verification efficiency has been significantly improved through libsecp256k1 and hardware upgrades, eliminating the need for protocol-level adjustments. The "faked confirmed transactions" essentially rely on cracking double SHA256 collisions, which, if achieved, would mean Bitcoin core security has been compromised.

Wang Chun further added that these issues are not sufficient to drive protocol modifications. Currently, only the "duplicate transactions" problem has some repair value and may be one of the few worthwhile changes to implement.
