Michael Saylor has warned that changes to Bitcoin’s consensus rules pose a greater long-term threat than rival cryptocurrencies, governments, or external competition.
Summary
- Saylor called internal rule changes Bitcoin’s “gravest threat” after the asset gained broad market recognition.
- He argued that consensus rules protect property rights, scarcity, settlement, and limits on power.
- Saylor said proposals such as BIP-110 could weaken block-space scarcity and miners’ fee revenue.
- Strategy recently joined eight companies pledging $15 million toward Bitcoin security research.
Saylor warns against capturing Bitcoin consensus
Strategy Executive Chairman Michael Saylor issued the warning in a series of X posts on Tuesday, describing Bitcoin’s consensus rules as its constitution. Those rules determine how ownership is recognized, how scarcity is maintained, how transactions settle, and what network participants can change.
“Bitcoin has won. Now it must survive victory,” Saylor wrote. “Its gravest threat is not an enemy at the gates, but corruption from within.”
He argued that changing the protocol to serve one group would infringe on the economic rights of miners, developers, investors, companies, custodians, and other users. Once one faction gains enough influence to rewrite the rules, he warned, competing groups may pursue changes through the same process.
That outcome could make protocol disputes permanent, according to Saylor. He said prolonged governance conflicts would drive away capital, slow development, weaken security, and leave Bitcoin with only a fraction of its potential.
Saylor expects Bitcoin could grow 100-fold and become part of the infrastructure supporting global capital markets. From that perspective, he argued that a poorly designed rule introduced today could restrict financial products, technologies, and economic activity that do not yet exist.
Why Saylor opposes BIP-110
Saylor’s latest comments extend his opposition to Bitcoin Improvement Proposal 110, a proposed temporary soft fork intended to reduce arbitrary data stored on the blockchain.
BIP-110 supporters argue that limiting some forms of data would ease storage and verification burdens for node operators. They also want Bitcoin to remain focused on monetary transactions rather than inscriptions, tokens, or file storage.
Saylor accepts that some on-chain data may have little value or could be linked to harmful activity. However, he argues that Bitcoin cannot reliably determine the purpose behind transaction data and should not use consensus rules to decide which valid, fee-paying transactions deserve block space.
“Bitcoin does not need guardians of purity,” Saylor wrote in his July 18 article. “It needs guardians of neutrality.”
His latest X thread widened that argument beyond BIP-110. Saylor also criticized proposals that add covenant functionality or increase block capacity, saying each approach creates different risks for Bitcoin’s base layer.
Bitcoin fee market and network security at stake
According to Saylor, restrictions on valid transactions could reduce competition for block space and weaken the fee market. Larger blocks, meanwhile, could dilute block-space scarcity while raising the bandwidth and hardware costs required to operate a node.
He also argued that covenants would make Bitcoin’s consensus rules more complex and introduce additional attack surfaces. These claims represent Saylor’s assessment of the proposals rather than an established consensus among Bitcoin developers.
Transaction fees will become increasingly important to miners as the block subsidy falls by half roughly every 210,000 blocks. Saylor warned that suppressing fee demand could reduce the income available to miners and weaken the financial incentives protecting the network.
His preferred approach is to keep the base layer simple, neutral, scarce, and secure. Developers can then build new functions through second-layer networks and applications, where adoption remains voluntary and failures have a more limited effect.
Strategy backs $15 million security effort
Saylor’s stance carries added relevance for US investors because Strategy has built its corporate model around holding Bitcoin and promoting enterprise adoption. He recently argued that companies are necessary for Bitcoin to develop into a global monetary network, placing corporate participation at the center of its next stage.
Strategy also joined Anchorage Digital, ARK Invest, BlackRock, Block, Blockstream, Coinbase, Fidelity Digital Assets, and Galaxy in forming the Bitcoin Security Consortium.
The nine firms pledged a combined $15 million over three years to support developers and researchers working on Bitcoin security, including preparations for potential quantum-computing threats. Members will direct their funding independently, while the consortium says it will neither control Bitcoin development nor take positions on individual protocol changes.
Saylor said upgrades should remain rare, conservative, and driven by necessity. His latest intervention places protocol restraint alongside corporate adoption and security funding as central parts of his long-term Bitcoin strategy.
