Michael Saylor, co-founder of Strategy and the largest publicly listed corporate Bitcoin holder, publicly opposed BIP-110 on July 11, a proposed one-year soft fork that would restrict non-financial data storage on the Bitcoin blockchain. Saylor argues the proposal introduces more systemic risk than the spam problem it targets, framing the issue as a governance question about who decides valid transactions. As of July 13, miner signaling for BIP-110 stood at approximately 1.3%, far below the required 55% threshold, with a voluntary signaling deadline around block 961,542 in August. Saylor's critique warns that embedding transaction-type discrimination in consensus rules compromises Bitcoin's structural neutrality. Strategy holds approximately 843,775 BTC, positioning Saylor's opposition as a statement from the largest corporate Bitcoin balance sheet.
Miner Signaling Stands at 1.3% Against 55% Threshold
As of July 13, miner support for BIP-110 registered approximately 1.3%, according to the public signaling monitor at bip110.org. The proposal requires a 55% miner signaling threshold for activation, with a voluntary deadline around block 961,542 in August. The 55% threshold is aggressive by historical Bitcoin governance standards. At current support levels, the proposal remains far from the activation requirement, though the threshold itself continues to function as a live governance benchmark.
BIP-110 Technical Scope Restricts Data Storage and Block Validation
BIP-110 would restore a tighter limit on OP_RETURN outputs, restrict larger data uploads, and reject blocks containing transactions that are valid under Bitcoin's current rules. Nodes adopting BIP-110 would enforce a narrower definition of acceptable transactions than non-adopting nodes. This creates a split scenario where consensus rules diverge based on node configuration, a structural concern Saylor highlighted in his critique posted to X and covered by the Bitcoin Foundation on July 11.
Saylor Argues BIP-110 Compromises Bitcoin Neutrality and Institutional Stability
Saylor's argument positions Bitcoin neutrality as a structural property the network cannot afford to compromise. He frames BIP-110 as a decision about which valid, fee-paying transactions the network should accept, rather than a technical spam-management measure. Saylor warns that if consensus rules can be modified to exclude data storage labeled as spam, the same mechanism becomes available for other transaction categories. Institutional investors who have followed Strategy's lead and the broader wave of corporate treasury adoption are implicitly betting on protocol stability. A governance mechanism that excludes valid use cases introduces a risk category unrelated to price or macroeconomic factors.
Fee Revenue and Market-Based Alternatives to Consensus Changes
Saylor argues that suppressing on-chain use cases, regardless of their aesthetic merit, affects demand for transaction fees. His position holds that market-based fees and individual relay policies are the correct instruments for managing unwanted data traffic, because they operate without altering consensus and can be reversed or adjusted without a network-wide coordination event. This approach avoids embedding judgment in the protocol layer while preserving flexibility for node operators and miners.
Governance Debate Surfaces Tensions Over Protocol Discrimination
Saylor is not the only prominent voice opposing BIP-110. Other long-standing Bitcoin contributors have also publicly rejected the proposal. The debate has surfaced tensions in Bitcoin governance over who holds effective veto power: miners, developers, node operators, or major holders. Questions remain about whether a 55% miner threshold constitutes a legitimate activation path for changes of this scope. With miner support at 1.3% six weeks before the August deadline and no clear institutional momentum, BIP-110 faces significant activation hurdles. The governance question Saylor raises — whether Bitcoin's consensus layer should ever discriminate between transaction types, and who makes that determination — remains unresolved.
FAQ
What is BIP-110 and why does Michael Saylor oppose it?
BIP-110 is a proposed one-year soft fork that would restrict non-financial data storage on the Bitcoin blockchain by tightening OP_RETURN output limits and rejecting blocks with certain valid transactions. Michael Saylor opposes BIP-110 because he argues it introduces systemic risk by compromising Bitcoin's neutrality and embedding transaction-type discrimination in consensus rules. Saylor posted his critique to X on July 11, framing the proposal as a governance question about who decides which valid, fee-paying transactions the network should accept.
What is the current miner support for BIP-110?
As of July 13, miner signaling for BIP-110 stood at approximately 1.3%, according to the public monitor at bip110.org. The proposal requires a 55% miner signaling threshold for activation, with a voluntary deadline around block 961,542 in August. At 1.3%, support remains far below the required threshold.
