F2Pool Co-founder Wang Chun: BTC Protocol Upgrade Should Not Include "Political Compromises"

F2Pool co-founder Wang Chun opposes practices similar to the U.S. bundling legislation in Bitcoin protocol upgrades, especially BIP-110 and BIP-54. He points out that time warp attacks do not provide significant advantages to miners, and protocol-level adjustments are no longer necessary; the only issue worth fixing is the double-spending problem.

BlockBeats message, April 4, F2Pool co-founder Wang Chun said in a post on the X platform that the Bitcoin protocol upgrade should not involve similar conduct to that of American politicians using a “package bill” to force through “some provisions that must pass but are unpopular,” and this is also an important reason for his opposition to BIP-110 and BIP-54.

In response to whether he has encountered any problems with any remediation procedures that use BIP-54, Wang Chun added that the “Timewarp” problem has been around for a long time and offers miners no significant advantage, because it is not possible to predict who will mine the next block. Its only practical use is to disrupt certain altcoins. Since it provides virtually no practical benefits to Bitcoin miners, there is no urgent need to modify it. In addition, block validation efficiency has been significantly improved by libsecp256k1 and hardware upgrades, so there is no need for protocol-layer adjustments. As for “forging already confirmed transactions,” it fundamentally depends on exploiting a broken double SHA256 collision; if it were to work, it would mean that Bitcoin Core security has been compromised.

Wang Chun added that none of the issues mentioned above are sufficient to drive protocol changes. At present, only the “duplicate transactions” problem has some remediation value, and it may be the only change (or one of very few changes) worth implementing.
