F2Pool co-founder Wang Chun: BTC protocol upgrades should not adopt approaches similar to “bundled bills”

Odaily reported that F2Pool co-founder Wang Chun stated on X that Bitcoin protocol upgrades should not adopt approaches similar to U.S. politicians using "omnibus bills" to force the passage of "certain necessary but unpopular clauses." This is also a major reason why he opposes BIP-110 and BIP-54.

When responding to whether he had encountered any issues with fixes using BIP-54, Wang Chun added that the "Timewarp" attack has existed for a long time and presents no significant advantage for miners, since it is impossible to predict who will mine the next block. Its only practical use is to interfere with certain altcoins. Because Bitcoin miners gain virtually no real benefit, there is no urgent need to change it. In addition, block validation efficiency has already improved significantly due to libsecp256k1 and hardware upgrades, so no adjustments are needed at the protocol level. As for "forging confirmed transactions," this essentially relies on breaking double SHA256 collisions, which, if successful, would mean that Bitcoin's core security has been breached. Wang Chun concluded that none of the above issues are sufficient to drive protocol modifications. Currently, only the "duplicate transactions" problem has some repair value and may be one of the few changes worth implementing.
