Adam Back and Michael Saylor Reject BIP 110 as Bitcoin Governance Debate Intensifies

TL;DR

• Adam Back and Michael Saylor have publicly opposed Bitcoin BIP 110, arguing it conflicts with Bitcoin’s decentralized and permissionless design.
• Back warned that implementing the proposal could divide the community and potentially lead to a Bitcoin network fork.
• Saylor said BIP 110 would turn a spam debate into a consensus change that invalidates currently valid, fee-paying transactions.
• The debate highlights ongoing disagreements over Bitcoin governance and how future protocol upgrades should be implemented.

Two of Bitcoin’s most influential figures have publicly opposed Bitcoin Improvement Proposal (BIP) 110, arguing that the proposal risks undermining the network’s long-standing principles of decentralization and permissionless access.

Blockstream co-founder Adam Back and Strategy Executive Chairman Michael Saylor both criticized the proposal, which seeks to change how certain Bitcoin transactions are treated in an effort to curb what supporters describe as network spam. Their comments add further weight to an increasingly divisive debate over Bitcoin’s future direction and governance. 

Back argued that BIP 110 attempts to dictate which transactions should be considered acceptable on the Bitcoin network. According to him, allowing consensus rules to selectively reject otherwise valid transactions runs counter to Bitcoin’s neutral and permissionless design.

He also warned that pushing the proposal without broad agreement across the ecosystem could ultimately split the network through a contentious fork rather than achieve meaningful consensus. 

Saylor echoed similar concerns, saying BIP 110 transforms what he described as a transaction “spam” debate into a protocol-level consensus change. In his view, introducing rules that invalidate transactions currently accepted by the network would establish a dangerous precedent that could have long-term consequences for Bitcoin’s governance.

Rather than focusing on disputes over transaction types, Saylor argued the community should prioritize addressing more fundamental threats facing the Bitcoin ecosystem.

Debate Over Bitcoin Transaction Filtering Continues to Divide the Community

BIP 110 was introduced as a proposal aimed at limiting arbitrary non-financial data stored on the Bitcoin blockchain. Supporters believe restricting these transactions would help preserve block space for monetary transfers and reduce blockchain bloat caused by inscriptions and similar applications. 

Critics, however, argue that Bitcoin’s consensus rules should remain content-neutral. They contend that if users are willing to pay transaction fees that comply with existing protocol rules, the network should not discriminate based on how transaction data is used.

The disagreement reflects a broader philosophical divide that has resurfaced several times throughout Bitcoin’s history. Previous debates over block sizes, Taproot, and Ordinals similarly raised questions about balancing innovation with preserving Bitcoin’s original monetary purpose.

Although some miners and node operators have expressed support for BIP 110, public signaling remains well below the threshold typically associated with broad network consensus, leaving the proposal’s future uncertain. 

Consensus Remains the Biggest Challenge on the Bitcoin Proposal

The latest comments from Back and Saylor highlight how difficult it can be to introduce protocol changes to Bitcoin without overwhelming community support.

Historically, major Bitcoin upgrades have required extensive coordination among developers, miners, exchanges, wallet providers, and node operators before activation. Several analysts note that proposals lacking broad agreement face significant hurdles and can risk creating competing versions of the network if implemented unilaterally. 

For now, BIP 110 remains one of the most closely watched discussions within the Bitcoin ecosystem. While supporters continue to argue that tighter limits on non-financial data would strengthen the network’s efficiency, opponents maintain that preserving Bitcoin’s censorship resistance and permissionless nature should remain the higher priority.

As the debate continues, the outcome is likely to shape not only how Bitcoin processes transactions but also how future protocol changes are debated and approved across the world’s largest cryptocurrency network.
