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.
Bitcoin soft fork proposal BIP-54, or "Consensus Cleanup," completed its specification in May 2026, according to ChainCatcher. The proposal is intended to fix four edge-case issues in Bitcoin’s consensus rules and does not introduce new Bitcoin features.
Wang Chun, co-founder of digital asset mining pool F2Pool, said he does not support BIP-54. He said that if the proposal reaches the required majority through the standard BIP-9 process, F2Pool will upgrade its mining nodes, but it will not issue an early support signal.
BIP-54 remains in testing
BIP-54 has been tested in Bitcoin Inquisition, a Signet-based testing environment. Mining pools MARA and ViaBTC have voluntarily produced compatible coinbase transactions.
The proposal’s formal activation parameters have not been determined, and voting on the Bitcoin mainnet has not been completed.
Different from the earlier BIP-110 proposal
An earlier proposal, BIP-110, sought to restrict some non-financial data in Bitcoin transactions. It did not receive enough miner support and stalled near block height 961635. BIP-54 does not involve restrictions on general script functionality.
