Michael Saylor and Adam Back, two prominent Bitcoin figures, have publicly opposed BIP 110, a proposal to modify Bitcoin's consensus rules to combat spam transactions. Saylor argued that spam does not represent the primary threat to Bitcoin and that altering consensus rules to address it could establish a dangerous precedent for future interventions.
Back took a stronger ideological stance, contending that the initiative contradicts Bitcoin's foundational principles by attempting to control participant behavior within the network. His criticism centers on the proposal's departure from Bitcoin's permissionless ethos and its implications for network governance.
BIP 110 seeks to introduce new transaction validation rules specifically targeting spam-related activity. The opposition from both figures signals potential resistance within Bitcoin's development community to consensus-layer changes motivated by transaction filtering, raising questions about the proposal's viability in the current political landscape of Bitcoin improvement discussions.
