F2Pool co-founder Wang Chun: The BTC protocol upgrade should not involve political compromises

F2Pool co-founder Wang Chun stated on platform X that the Bitcoin protocol upgrade should not adopt practices similar to those of American politicians who forcefully push "some necessary but unpopular provisions" through "omnibus bills." This is also an important reason for his opposition to BIP-110 and BIP-54.

In response to whether there were issues encountered when using any fixes for BIP-54, Wang Chun added that the timewarp attack issue has been around for a long time and does not provide significant advantages for miners, as it is impossible to predict who the next block miner will be. The only practical use is to disrupt certain altcoins. Since there are almost no real benefits for Bitcoin miners, there is no urgent need to modify it. Additionally, block validation efficiency has significantly improved due to libsecp256k1 and hardware upgrades, making protocol layer adjustments unnecessary. Furthermore, the essence of "forging confirmed transactions" relies on breaking the double SHA256 collision, and if established, it would mean that Bitcoin core security has been compromised.

Wang Chun added that the aforementioned issues are not sufficient to drive protocol modifications. Currently, only the "duplicate transactions" issue has some repair value and may be one of the few changes worth implementing.
