Michael Saylor critiques BIP 110, warns of neutrality risks

Michael Saylor opposes BIP 110, warning it would restrict valid transactions, introduce governance, and threaten Bitcoin’s neutrality and security. He urges managing unwanted activity without consensus changes.

Michael Saylor has released a comprehensive critique of Bitcoin Improvement Proposal 110 (BIP 110), outlining over 100 reasons for his opposition. He contends that BIP 110, which introduces seven temporary consensus restrictions—including limits on OP_RETURN outputs and data-heavy transactions—would restrict currently valid transactions and bring governance intervention into Bitcoin’s use cases. Saylor warns that lowering the miner signaling threshold for activation from the standard 95% to 55% could increase the risk of a chain split, negatively affecting miner fee revenue and overall network security. He argues that existing tools already empower node operators and miners to manage unwanted transactions without changing consensus rules. Saylor emphasizes that Bitcoin’s protocol should remain neutral, with transaction fees, miner choice, and local node policies determining blockspace use. He cautions that using consensus changes to filter transactions sets a dangerous precedent and could undermine Bitcoin’s foundational neutrality.
