Saylor Rejects BIP 110: 'Bitcoin Does Not Need Guardians of Purity'

Michael Saylor has urged developers to reject BIP 110, a proposed temporary softfork aimed at reducing arbitrary data stored through Bitcoin transactions. The proposal would impose seven consensus restrictions, including capping some script sizes and restricting Taproot control blocks.

Saylor argues that the package 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.

The proposal, which reached 'Complete' status under BIP 3 on June 25, would temporarily cap some script sizes, restrict Taproot control blocks, and prevent spending through undefined witness versions. Saylor agrees with the broader goal of protecting node operators and preserving affordable transactions but argues that BIP 110 uses seven consensus rules to reject valid, fee-paying activity without measuring the costs those transactions impose.

Saylor's strongest concern involves future development, as the proposal would close reserved technical options for later upgrades. He objects to bundling all seven restrictions into one package and using a 55% miner-signaling threshold below the 95% level associated with BIP 9 deployments.
