Michael Saylor, CEO of MicroStrategy, has recently identified protocol mutability, specifically the push for complex new features, as the "greatest risk" facing Bitcoin. In a provocative social media post, Saylor implied that "ambitious opportunists advocating protocol changes" could potentially undermine the main value proposition of the world's flagship cryptocurrency, which is its inherent immutability. His comments directly target a growing faction of developers and "activist" Bitcoiners who champion ambitious changes to the protocol.

Saylor's remarks are likely aimed at controversial upgrades such as BIP110. This proposal, authored by the pseudonymous developer Dathon Ohm in late 2025, seeks to aggressively limit arbitrary data storage on the Bitcoin blockchain. BIP110 is widely viewed as a proxy in the ongoing "anti-spam" philosophical debate championed by the controversial Bitcoin developer Luke Dashjr. The primary software implementing BIP-110 is Bitcoin Knots, which is maintained by Dashjr. So far, this soft fork has garnered support from more than 2% of all Bitcoin nodes.

The tension between Saylor's perspective and that of protocol modifiers escalated significantly between 2024 and 2025, particularly surrounding MicroStrategy’s launch of "MicroStrategy Orange." This decentralized identity protocol is built directly on Bitcoin using Inscriptions. Saylor has consistently defended the right of users to inscribe various forms of data, including JPEGs, IDs, and text, on Bitcoin, provided they pay the required transaction fees. In stark contrast, Dashjr has labeled Inscriptions and Ordinals as an "attack" on Bitcoin, advocating for strict code updates to address what he perceives as misuse.

A proponent of Dashjr responded to Saylor's latest social media post, stating, "Nobody in the Knots/BIP-110 is an opportunist, because none of us make any money from reckless protocol development. We simply want to keep our savings safe and preserve Bitcoin as sound money for future generations." This highlights the differing motivations perceived by the various parties involved in the debate. Additionally, there are those who explicitly advocate for Bitcoin's ossification, a complete cessation of protocol changes. Adam Simecka, founder of Manna, encapsulates this view with his assertion: "Stop changing Bitcoin. It isn't broken." This ongoing philosophical divide underscores the complex challenges facing Bitcoin's future development and core identity.
