Saylor warns Bitcoin spam-filter proposal risks politicising network’s rules
Strategy's Michael Saylor opposes BIP 110, arguing that filtering Ordinals-style data threatens Bitcoin's neutrality as a settlement network.
Michael Saylor, executive chairman of Strategy and the largest corporate holder of bitcoin, has publicly opposed a proposed Bitcoin protocol change known as BIP 110, warning that empowering node operators to filter certain transactions would compromise the network’s claim to neutrality. His intervention adds a heavyweight institutional voice to a technical dispute that has divided Bitcoin’s developer community for months.
BIP 110 proposes to add seven temporary consensus rules to Bitcoin for a period of one year, aimed at curbing what its proponents describe as network “spam” — non-monetary data inscriptions modelled on the Ordinals protocol. The proposal would cap new output scripts at 34 bytes and restrict OP_RETURN outputs to 83 bytes, effectively narrowing the space available for embedding arbitrary data on-chain.
A proposal with no miner backing
For BIP 110 to activate, at least 55% of network nodes would need to signal support for validating blocks under the new rules, with a target activation point set at block 965,664. According to the reported signalling data, miner support currently stands at 0%, leaving the proposal without the operational backing it would need to take effect.
The stalled signalling underscores a broader tension within Bitcoin’s governance model, in which changes to consensus rules require broad, voluntary coordination among miners, node operators and developers rather than a formal regulatory process.
Saylor’s structural objection
Saylor’s opposition is not framed as a defence of Ordinals inscriptions themselves, but as a warning about precedent. His argument is that Bitcoin’s consensus rules should determine whether a transaction is technically valid, not whether it is economically or culturally desirable — and that once the network begins distinguishing between “acceptable” and “unacceptable” transaction types, it risks abandoning the neutral, permissionless character that underpins its value proposition to institutional holders.
That framing matters for the growing base of corporate and institutional bitcoin holders, for whom the asset’s appeal rests partly on the assumption that its rules are fixed, apolitical and resistant to discretionary gatekeeping. Strategy itself holds one of the largest corporate bitcoin treasuries in the world, giving Saylor’s public stance added weight in a debate that would otherwise remain confined to developer mailing lists.
Why it matters for markets
The dispute over data-carrying transactions such as Ordinals inscriptions has simmered since the format’s emergence, pitting those who prioritise Bitcoin as a pure monetary settlement layer against those who see broader utility — and transaction fee revenue — in supporting arbitrary data storage on-chain. With miner signalling at zero and no clear timeline for consensus, BIP 110 currently has no realistic path to activation, but the episode illustrates how governance disputes, rather than price action alone, can shape institutional confidence in Bitcoin’s long-term neutrality.
For UK and European institutions increasingly exposed to bitcoin through exchange-traded products and corporate treasuries, such protocol-level debates carry indirect but real implications: any perception that Bitcoin’s rules can be altered to favour particular use cases could complicate its positioning as a neutral, censorship-resistant asset relative to traditional stores of value.
