Michael Saylor, chairman of Strategy, has intensified his public opposition to Bitcoin Improvement Proposal 110, warning that this temporary soft fork risks undermining Bitcoin's core principle of neutrality by enforcing new consensus rules that restrict transaction data.

Controversy Over Data Restrictions and Consensus

BIP 110, formally named the Reduced Data Temporary Softfork, proposes limiting data-heavy transactions by capping OP_RETURN outputs at 83 bytes and payloads at 256 bytes, while exempting outputs created before activation. The rules would remain active for roughly one year. Its proponents argue that these restrictions would alleviate storage and bandwidth burdens on full nodes, reducing arbitrary data storage that complicates network operation.

However, Saylor contests that Bitcoin’s consensus layer should not discriminate between valid transactions based on data content or structure, as the protocol cannot interpret the intent behind transaction data. In his article “110 Reasons BIP 110 Is a Bad Idea,” Saylor stresses that miners and fee markets not consensus rules should manage transaction prioritization. He advocates for guardians of neutrality rather than guardians of purity.

This dispute highlights a foundational tension: whether consensus rules should evolve to regulate transaction content or remain neutral arbiters of validity. Saylor’s view emphasizes that imposing restrictions risks fracturing the community and setting dangerous precedents for future consensus changes.

Support from miners remains minimal, with signaling near zero against the 55% threshold required for activation. Adam Back, Blockstream co-founder, aligns with Saylor in cautioning that pushing BIP 110 without broad consensus could split the network. Meanwhile, developer Luke Dashjr continues to back the proposal, reflecting ongoing division amid increasing debate over data-heavy uses like Ordinals and Runes.

The outcome of this debate could shape not only transaction policy but also the broader governance dynamics of Bitcoin. The resistance against limiting data within transactions shows the community’s attachment to Bitcoin’s neutral base-layer ethos.
