Michael Saylor, executive chairman of Strategy (NASDAQ: MSTR), escalated his opposition to BIP-110 on Tuesday, calling the controversial Bitcoin proposal fundamentally at odds with the network’s founding principles.
Saylor took to X to voice his objections, writing that the impulse behind BIP-110 runs counter to the values Bitcoin was built upon.
“The impulse to change Bitcoin’s rules merely to prevent others from using Bitcoin in ways you disapprove of is statist and alien to a community rooted in liberty, property rights, free markets, natural law, and Austrian economics,” Saylor wrote.
He concluded his post with a sharp rebuke of the proposal’s underlying logic, writing: “BIP 110 would impose monetary purity by fiat.”
BIP-110 would place a cap on the amount of non-payment-related data, such as images or files, that can be attached to Bitcoin transactions on the network.
Saylor has previously argued that the proposal’s most dangerous aspect is not the spam it claims to eliminate, but the precedent it sets for restricting legitimate, fee-paying transactions.
He has warned that BIP-110 could push Bitcoin toward rule changes determined by a small subset of the network rather than the network as a whole, threatening its decentralized character.
The proposal has drawn criticism from several prominent figures in the Bitcoin developer community, with concerns spanning both its technical design and its activation process.
Blockstream CEO Adam Back said last week that Bitcoin had “robustly rejected” the proposal, describing it as an attempt to “police other people” rather than address any genuine technical problem.
Back went further, suggesting that supporters of BIP-110 had one realistic path forward, writing: “Your permissionless recourse is to club together and create a fork. But bitcoin won’t be joining it.”
Bitcoin Core developer Greg Maxwell has warned that BIP-110 may invalidate pre-signed transactions, adding another layer of technical concern to the already heated debate.
Developer Peter Todd has pointed out that the proposal relies on a User Activated Soft Fork approach rather than broader miner consensus, and that it lacks any defined activation timescale.
Opposition extends beyond technical objections, with concerns also raised over the pseudonymous authorship of the proposal and suspicion that it is backed by mining companies.
Miner support for BIP-110 remains near-absent, reinforcing fears that pushing the proposal forward could fracture the Bitcoin network entirely.
MSTR shares were trading up more than 3% during Tuesday’s midday session, moving alongside a broader uptick in crypto market sentiment.
On Stocktwits, retail sentiment around MSTR shifted to a neutral position from bearish territory, though chatter around the stock remained at low levels over the prior day.
The broader crypto market received a boost after the White House reportedly agreed on ethics language in the CLARITY Act, a development that could accelerate the bill toward a Senate floor vote.
