F2Pool Co-founder Wang Chun: Bitcoin Protocol Upgrades Should Avoid 'Political Compromise'

On April 4, F2Pool co-founder Wang Chun stated on platform X that Bitcoin protocol upgrades should not adopt practices similar to U.S. politicians using ‘omnibus bills’ to force through ‘some necessary but unpopular provisions.’ This is a key reason for his opposition to BIP-110 and BIP-54. In response to whether there were issues with any fixes using BIP-54, Wang Chun added that the ‘Timewarp’ attack issue has been longstanding and does not provide significant advantages to miners, as it is impossible to predict who the next block miner will be. Its only practical use is to disrupt certain altcoins, and since it offers almost no real benefits to Bitcoin miners, there is no urgent need for modifications. Furthermore, block validation efficiency has significantly improved due to libsecp256k1 and hardware upgrades, eliminating the need for protocol layer adjustments. The issue of ‘forging confirmed transactions’ fundamentally relies on breaking the double SHA256 collision, and if successful, it would mean that Bitcoin’s core security has been compromised. Wang Chun concluded that the aforementioned issues are insufficient to drive protocol changes, and currently, only the ‘duplicate transactions’ issue holds some repair value, possibly being one of the few changes worth implementing.
