Saylor Launches Scathing Attack on BIP-110, Warning of Network Split Risks

Michael Saylor, executive chairman of Strategy, has forcefully opposed a new proposal aimed at cleansing Bitcoin’s blockchain of 'spam,' warning that such a move could fundamentally alter the operational integrity of the world's largest cryptocurrency network.

The Assault on Protocol Neutrality

The Bitcoin Improvement Proposal (BIP) 110 seeks to temporarily restrict arbitrary data to focus on core monetary functions. Saylor argues this 'cure is more dangerous than the condition,' asserting that using consensus to narrow valid activity constrains future options and complicates deployment. Saylor's primary objection rests on the 'no-questions-asked' nature of money; the network cannot distinguish whether bytes represent an image, a contract, or metadata. By banning 'spam,' the protocol would effectively elevate human judgment into protocol law, overturning Bitcoin's conservatism.

A Dangerous Precedent in Consensus Rules

A critical point of contention is the proposal to lower the upgrade approval threshold from 95% to just 55% of miners. Saylor warns this aggressive threshold could encourage disagreement, significantly increasing the probability of a network split into competing versions. As his firm holds 843,775 BTC, worth $54.31 billion, making it the world's largest publicly listed bitcoin treasury company, Saylor emphasizes that BTC's appeal to institutional investors lies in its stable, permissionless environment—a reputation that could be dented by the new proposal.

Economic Risks to Miner Incentives

Suppressing certain network uses could lead to a 'chilling effect' on innovation. Crucially, Saylor notes that lower aggregate fee demand could weaken miner incentives to commit hash power. As block subsidies continue to halve, reduced fee revenue poses a direct threat to Bitcoin's security model. Rather than altering the underlying code, Saylor suggests that market-based fees and individual relay policies are the appropriate mechanisms to manage capacity without modifying sacred consensus rules.

From a tokenomics standpoint, proposals like BIP-110 are fundamentally flawed because they attack the demand side of the security budget. As the block subsidy diminishes, transaction fees become the primary line of defense for network security. By censoring specific data payloads—often dismissed as spam—the protocol artificially caps the fee market. As a quant analyst, I view this as a negative supply shock to the revenue model: restricting use cases today tightens the fee pressure tomorrow, potentially leaving the network under-secured when the subsidy runs dry.
