Michael Saylor condemns Bitcoin BIP 110 proposal as a fiat‑imposed monetary purity measure

Michael Saylor, Executive Chairman of Strategy (formerly MicroStrategy), reiterated his opposition to Bitcoin Improvement Proposal (BIP) 110, describing it as an attempt to impose "monetary purity by fiat" that would undermine Bitcoin’s freedom and decentralisation. In a July 19 X post he shared a lengthy article titled "110 Reasons BIP 110 Is a Bad Idea," arguing the soft‑fork would restrict valid transactions and set a precedent for future data‑storage limits on the blockchain.

Saylor’s stance echoes that of Blockstream CEO Adam Back, who also warned that BIP 110 would downgrade Bitcoin rather than clean it up. The proposal seeks to limit the size of arbitrary data (such as OP_RETURN inscriptions) stored on the chain for a one‑year period, with a reduced 55 % consensus threshold for activation and mechanisms to reject non‑supporting blocks. Both Saylor and Back contend that consensus rule changes should be reserved for clear, critical bugs, not for managing spam or data‑storage policies, and that existing node and miner policies are sufficient to handle such concerns.

The debate reflects broader tensions in the Bitcoin community over how to balance network utility, node load, and the currency’s core monetary properties.
