BIP 110 Controversy: Saylor's Battle for the Moat — How Bitcoin's 'Spam' Ban Could Shake the World's Largest Blockchain

In the ongoing governance struggle within the Bitcoin community, a proposal aimed at purifying the blockchain of "data pollution" is sparking unprecedented division. Michael Saylor, Executive Chairman and Co-Founder of Strategy (formerly MicroStrategy), recently published a lengthy analysis strongly opposing Bitcoin Improvement Proposal (BIP) 110. He warns that this proposal, seemingly intended to restore Bitcoin's "sound money" essence, could fundamentally undermine the operational pillars of the world's largest blockchain—from neutrality and decentralization to miner incentives.

Proposal Core: A Soft Fork Targeting "Spam"

BIP 110's intent seems clear: implement a one-year temporary soft fork, adding seven different consensus restrictions, including limiting data payload size and rejecting certain script execution, to curb the proliferation of non-monetary data storage on the Bitcoin blockchain. Supporters argue that Bitcoin's core value is a peer-to-peer digital cash system, not to be occupied by inscriptions, NFTs, or arbitrary metadata triggered by protocols like Ordinals. They claim the blockchain is being clogged by "spam," causing soaring transaction fees and confirmation delays, deviating from Satoshi's original whitepaper vision.

However, critics are equally vocal. They argue this is not a technical optimization but an attempt to restrict Bitcoin's use through protocol-level censorship, essentially writing human judgment into consensus rules. Saylor's position is at the forefront of this debate.


"No-Questions-Asked" Principle: Saylor's Core Moat

In Saylor's analysis, the most striking argument is Bitcoin's "no-questions-asked" nature. He writes: "Bitcoin cannot read intent. The network cannot know whether a byte represents an image, evidence, a contract, metadata, an authentication record, or a future application." This assertion directly targets BIP 110's logical blind spot: once the consensus layer begins to judge what data is "spam," it must define what constitutes "valuable" transactions.

Granting this definition power to the protocol equates to elevating human judgment to protocol law. Bitcoin's conservatism is precious precisely because of its "no censorship, no distinction, no discrimination" neutrality. Banning "spam" appears to clean up redundancy, but in reality, it sets the first subjective valve on the blockchain. Saylor stated directly: "The proposed solution is more dangerous than the problem itself. BIP 110 will use the consensus mechanism to restrict valid activities, constrain future choices, increase deployment complexity, and set a precedent that cannot be erased later."

Lowered Approval Threshold: The Sword of Damocles over Network Split

The most controversial mechanism change in BIP 110 is lowering the miner consent threshold from the usual 95% to just 55%. Saylor called this change "too radical" and warned it could directly lead to network splits and widespread market uncertainty. Lowering the approval threshold weakens minority opposition but also encourages more divergence—when approval votes barely exceed half, opponents have every incentive to fork and form a competing version.

For institutional investors, Bitcoin's biggest appeal is precisely its long-term stable and permissionless environment. Saylor clearly stated that if the new proposal is implemented, this appeal will be weakened. "Bitcoin does not need guardians of purity," he asserted, "It needs guardians of neutrality." Lowering the threshold is essentially a destruction of consensus rules, turning Bitcoin from a hard currency that "no one can change" into a flexible protocol that "a quasi-majority can modify."

Economic Backlash: How Lower Fees Threaten Security?

Saylor's analysis also touches on an economic paradox overlooked by supporters. By restricting certain uses of the network—even if those uses are considered "spam"—overall fee demand will drop. Against the backdrop of ongoing Bitcoin block reward halvings, fee income is becoming increasingly important. Lower fee income will reduce miners' incentive to invest in hashing power, ultimately threatening the security of the entire network.

This argument overturns the simplistic notion that "cleaning spam = optimizing the system." In fact, the inscription craze brought by the Ordinals protocol, while causing network congestion, has also significantly boosted miner revenue. During the halving cycle, this non-traditional use has actually provided miners with additional economic support. If this income source is forcibly shut down without other compensation mechanisms, Bitcoin will be at a disadvantage in the long-term security game.

Alternative: The Hand of the Market, Not the Sword of Code

Facing the "spam" issue, Saylor did not avoid it but proposed a solution more in line with Bitcoin's spirit: using existing better tools to manage network capacity. He noted that market-based fees and individual relay policies are the appropriate approach, without altering the sacred consensus rules.

The core of this approach is: if someone doesn't like certain transaction content, they can configure their node settings to block its propagation (relay policy), or let market fees naturally filter out "spam" users through higher transaction costs. This method neither modifies the underlying blockchain rules that apply to everyone, nor does it deprive users of choice. In short, return the right to judge to individual nodes, rather than elevating it to the protocol level.

Conclusion: Guarding Neutrality, Not Purity

Saylor's opposition has sparked widespread discussion in the Bitcoin community. His company Strategy holds 843,775 bitcoins (worth $54.31 billion as of Sunday), and as the world's largest publicly traded Bitcoin treasury company, his voice carries significant weight. But more importantly, the principle he defends—the indiscriminate neutrality of the blockchain—concerns Bitcoin's long-term survival as digital gold.

The BIP 110 controversy is essentially another ideological battle in the Bitcoin community over scaling and positioning. In the past, we witnessed the block size war; today, we see the data storage war. Each debate is a growing pain in Bitcoin's self-evolution. But Saylor's warning is worth pondering: If we allow the protocol to restrict "spam" today, will it restrict privacy tools tomorrow? Will it restrict novel custody solutions or enterprise applications the day after? Once the door to censorship is opened, Bitcoin will no longer be that permissionless open financial system.

Ultimately, Saylor's closing remark is apt—Bitcoin truly needs not "guardians of purity," but "guardians of neutrality." On the path to becoming a global currency, the cost of maintaining neutrality may be temporary inefficiency and chaos, but the cost of losing neutrality will be the soul of the entire network.
