Saylor Warns BIP 110 Could Undermine Bitcoin Neutrality
The BIP 110 proposal would temporarily restrict non-financial data on Bitcoin, but Saylor says its broad rules could hurt neutrality and future extensions like BitVM.
Key Takeaways
- Michael Saylor is urging Bitcoin developers to reject BIP 110, saying it would weaken Bitcoin’s protocol neutrality.
- BIP 110 is designed to temporarily limit non-financial data on the Bitcoin blockchain, but Saylor argues the seven consensus restrictions are too broad.
- The proposal has little miner support, and the debate is now centered on Bitcoin governance, future upgrade flexibility, and fee-based blockspace management.
Michael Saylor is urging Bitcoin developers to reject BIP 110. The MicroStrategy chairman says the proposal tries to fix a real issue with a remedy that is even riskier, since it would weaken the protocol neutrality of Bitcoin for what he sees as a temporary and mostly symbolic result.
What BIP 110 Wants to Change
BIP 110, also called the Reduced Data Temporary Softfork, is meant to temporarily limit certain kinds of non-financial data on the Bitcoin blockchain. Its authors want to move Bitcoin closer to its original purpose as a peer-to-peer payments network, rather than a place to store other types of content.
Saylor says he supports that goal in principle. He also wants node operators shielded from unnecessary costs and believes payments should remain cheap. Even so, he argues the proposal’s seven consensus restrictions are too heavy-handed because they would affect valid, fee-paying transactions based only on the content they include.
Those limits cover script size, Taproot control blocks, and spending undefined witness versions. In Saylor’s view, that is a rough stand-in for a cost that was never properly measured.
Why the Upgrade Is Controversial
The proposal reached Complete status under BIP 3 in June. That means the authors have finished their work, but it does not mean the wider community has signed off. One key detail is that outputs created before activation would be exempt, and Saylor says that protection matters, even if it is not enough on its own.
The fight also comes down to Bitcoin’s future upgrade space. The protocol deliberately keeps some technical options unused so later upgrades can be added without breaking older software. BIP 110 would close off part of that space, including features that could matter for BitVM, an experimental approach for building complex agreements on Bitcoin without a trusted intermediary.
Saylor’s criticism echoes earlier pushback from Adam Back, who expects the effort to lose momentum within a few weeks once mandatory signaling becomes necessary. Miner support is also weak. Based on current figures, less than 1 percent of miners are signaling for BIP 110.
What This Says About Bitcoin Governance
For European crypto readers, the debate is a reminder of how difficult Bitcoin governance can be, even when the proposal is highly technical. The issue is not just about data on the blockchain. It is also about how much flexibility the network should preserve for future upgrades and which transactions should fall inside the rules.
Saylor instead favors fees and a voluntary relay policy, arguing that those tools can already manage blockspace without judging transaction content. Critics say the 55 percent miner-signaling threshold and the roughly one-year timeline make the proposal especially sensitive, particularly now that broad consensus looks unlikely.
At its core, the dispute is still the same: should Bitcoin focus on protecting a neutral base layer, or should it leave room for new use cases that want to use the blockchain for non-financial data as well? For now, that question remains open.
