Bitcoin BIP-110 Proposal Lowers Protocol Upgrade Threshold to 55%, Sparking Community Divide

According to BlockBeats, on July 20, the Bitcoin community became engulfed in heated debate over BIP-110, a controversial proposal to reduce the mining approval threshold for protocol upgrades from 95% to 55%. The proposal also aims to restrict arbitrary data on-chain (such as limiting transaction outputs to 34 bytes and capping OP_RETURN at 83 bytes) to reduce blockchain usage by inscriptions and Runes, with an August deadline for potential user-activated soft fork (UASF) activation.

BIP-110 has polarized the community. Supporters argue it would ease node operator burden and curb spam transactions, while prominent critics including developer Jameson Lopp and billionaire Michael Saylor warn the proposal could undermine Bitcoin's neutrality, impede Layer 2 development, and freeze existing UTXOs. Saylor stated the governance risks outweigh any problem-solving benefits. Current miner support remains extremely low, and the proposal's activation prospects remain highly uncertain.
