Bitcoin BIP-54 specification is complete, while F2pool declines early activation support

Bitcoin’s proposed soft fork BIP-54, known as “Consensus Cleanup,” completed its specification in May 2026, according to the report cited by Odaily. The proposal is designed to fix four consensus rule boundary issues and does not add new Bitcoin features. On Aug. 10, F2pool co-founder Wang Chun said he does not support BIP-54. He added that if the proposal clears the standard BIP-9 process and secures the required majority, F2pool will upgrade its mining nodes, but it will not signal support ahead of time. BIP-54 has already been tested in Bitcoin Inquisition, a Signet-based testing environment. Mining pools MARA and ViaBTC have voluntarily produced compatible coinbase transactions there. The report also said final activation parameters have not been set and voting on Bitcoin mainnet has not been completed. It contrasted BIP-54 with the earlier BIP-110 proposal, which sought to limit certain non-financial data in Bitcoin transactions, failed to win enough miner support, and stalled around block height 961635. BIP-54 does not restrict general script functionality.

Bitcoin BIP-54 spec completed as F2Pool says it will not signal early support

The specification for Bitcoin soft fork proposal BIP-54, known as "Consensus Cleanup," was completed in May 2026, according to ChainCatcher. The proposal is designed to fix four edge-case issues in Bitcoin’s consensus rules and does not add new functionality to the network. F2Pool co-founder Wang Chun said he does not support BIP-54, though he added that the mining pool would upgrade its mining nodes if the proposal secures the required majority through the standard BIP-9 activation process. He also said F2Pool would not send an early support signal. BIP-54 has already been tested in Bitcoin Inquisition, a Signet-based testing environment. Mining pools MARA and ViaBTC have voluntarily produced compatible coinbase transactions there. The proposal’s final activation parameters have not yet been set, and voting on Bitcoin mainnet has not been completed. The report also noted that BIP-110, an earlier proposal that sought to restrict some non-financial data in Bitcoin transactions, failed to win enough miner support and stalled near block height 961635. Unlike BIP-110, BIP-54 does not seek to restrict general script functionality.

F2Pool Co-founder Wang Chun Doesn't Support BIP-54, Will Update Nodes if BIP-9 Threshold Met

Wang Chun, a co-founder of the mining pool F2Pool, said on Aug. 11 that the firm does not, for now, support BIP-54, a bitcoin protocol upgrade proposal that has been discussed recently in the community. According to BlockBeats, in a public post Chun said his team would update the mining pool's nodes if the proposal advances strictly through BIP-9, bitcoin's established improvement proposal activation mechanism, and reaches the required supermajority signaling threshold. Until those formal activation conditions have been met, F2Pool will not take part in BIP-54 signaling votes, he added. BIP-54 is one of the protocol upgrade proposals recently discussed in the bitcoin community, and it also involves adjustments to the network's consensus rules. Chun's statement reflects a cautious attitude among some miners toward the proposal, as well as a preference for advancing upgrades through the standardized BIP-9 process and through community consensus. BlockBeats reported the development on Aug. 11.

F2Pool co-founder Wang Chun says he does not back BIP-54 for now

F2Pool co-founder Wang Chun said his team does not currently support the BIP-54 proposal and will not take part in signaling votes before the proposal meets its formal activation requirements. He said the team would update its mining pool nodes only if BIP-54 moves forward under the BIP-9 activation process and reaches the required absolute supermajority signaling threshold. BIP-54 is one of the protocol upgrade proposals recently under discussion in the Bitcoin community and involves changes to Bitcoin consensus rules. Wang Chun’s comments point to a cautious stance among some miners, with preference given to a standardized BIP-9 process and broader community consensus before any upgrade proceeds.

F2Pool Co-Founder: OCEAN Pool CTO Luke Dashjr's BIP-110 Fork Failed, Financial and Reputational Bankruptcy

Wang Chun, co-founder of F2Pool, said OCEAN Pool co-founder and CTO Luke Dashjr is both financially and reputationally bankrupt. His remarks follow the Bitcoin BIP-110 fork struggling just eight hours after launch, securing too little hash power to produce more than two blocks.

Wang Chun: BIP-110 Fork Faces Collapse, Luke Dashjr Bankrupt Financially and in Credibility

Wang Chun, co-founder of F2Pool, the third-largest bitcoin mining pool, said on X that Luke Dashjr, co-founder and CTO of OCEAN pool, is bankrupt both financially and in terms of personal credibility. Wang also said that changing the proof-of-work algorithm would not produce good results. His comments follow reports that the Bitcoin BIP-110 fork faced collapse within eight hours of activation, supported by insufficient hash power and yielding only two blocks.

SBI shuts Bitcoin mining pool as top three pools near 60% of network hashpower

SBI Crypto, the Bitcoin mining arm of Japan’s SBI Group, shut down its mining pool on July 31 after five years of operation, according to a customer notice signed by CEO Hiroaki Morita. The pool stopped accepting hashpower at 7:00 a.m. Japan time on July 31, or 22:00 UTC on July 30, and any hashpower submitted after that point would not count toward final payouts. As of June 30, the pool’s seven-day average hash rate stood at about 20.9 EH/s, equal to roughly 2.2% of the Bitcoin network, but that figure had already fallen about 64% over the month leading up to the shutdown. SBI did not give a reason for the closure and instead directed customers to Braiins, Luxor Pool, or NeoPool. The timing has drawn attention because Hashrate Index data shows Foundry USA, AntPool, and F2Pool together recently accounted for about 60% of Bitcoin block production, with their share reaching around 64.8% in the week of July 20. If ViaBTC is added, the top four pools come close to 70%, reviving debate over mining concentration on Bitcoin.
