Saylor Slams BIP 110 as Threat to Protocol Neutrality

Michael Saylor has spoken out against BIP 110, a proposal that aims to reduce arbitrary data stored through Bitcoin transactions. The proposal includes seven temporary consensus restrictions that would limit script sizes, restrict Taproot control blocks, and prevent spending through undefined witness versions.

Saylor, executive chairman of Strategy, formerly MicroStrategy, argues that the proposal threatens protocol neutrality and uses a 55% miner-signaling threshold that is too low for a disputed change. He supports market fees and voluntary relay policies instead of consensus rules that judge transactions by their perceived purpose.

BIP 110 aims to reduce node costs and keep block space focused on payments, but Saylor believes it uses seven consensus rules to reject valid, fee-paying activity without measuring the costs those transactions impose. The proposal has reached 'Complete' status under BIP 3, indicating that its author considers the draft ready rather than showing broad community support.

Saylor's strongest concern is that the proposal would close reserved technical options for later upgrades and bundle all seven restrictions into one package. He argues that Bitcoin does not need 'guardians of purity', but rather 'guardians of neutrality.'
