Saylor Opposes Bitcoin BIP-110, Says It Risks a Network Split

Michael Saylor, co-founder and chairman of Strategy, has publicly opposed BIP-110, a proposed Bitcoin soft fork intended to curb spam on the network.

The Block reported on July 19 that Saylor had posted on X on July 18 under the headline "110 Reasons Why BIP-110 Is a Bad Idea," arguing the proposal could create bigger risks than the problem it is meant to solve.

BIP-110 is a temporary soft-fork proposal to limit large-data transactions on the Bitcoin network. First introduced in October 2025, it would impose multiple restrictions on data-heavy transactions for one year through a client based on Bitcoin Knots.

Saylor argued that Bitcoin's consensus rules should not judge the "purpose" of transactions that pay normal fees. Nodes and miners can choose not to relay or mine unwanted data. But the consensus rules themselves should be aimed at clearly proven problems such as actual denial-of-service attacks or validation risks.

At the end of his post, he criticized BIP-110 as a "Bitcoin Iatrogenic Proposal," adding: "What Bitcoin needs is not guardians of purity, but guardians of neutrality."

BIP-110 is due to enter its mandatory signaling period around Aug. 7, with the rule set to take effect around Sept. 1. Its current signaling rate stands at about 0.86%, far below the 55% needed for early lock-in.

There are also concerns in the market that BIP-110 nodes could break off into a minority chain if support remains at current levels and they reject most non-signaling blocks. BIP-110 supporters also estimate current node support at about 7% to 15% and acknowledge the proposal may fail.

Separately, on the following day Saylor posted a chart showing Strategy's history of Bitcoin purchases along with the message, "What's next?" His recent weekend posts, however, have not always been followed by disclosures of additional purchases, leaving the market focused on Strategy's next capital-allocation move.
