Saylor and Back to BIP-110: not in our blockspace 🧱

Strategy executive chairman Michael Saylor and Blockstream CEO Adam Back have reaffirmed their opposition to BIP-110, a proposed temporary Bitcoin fork designed to restrict non-monetary transactions on the network. Bitcoin Improvement Proposal-110 was introduced in December 2025 by pseudonymous developer "Dathon Ohm," with support from Ocean protocol founder Luke Dashjr, in an effort to curb Ordinals-style data inscriptions that proponents describe as "spam." Saylor and Back have signaled concern that the proposal itself poses a more serious risk to Bitcoin's credibility than the activity it aims to limit. "There are 110 things more dangerous to Bitcoin than spam," Saylor wrote on X on Saturday, adding that BIP-110 could invalidate ordinary transactions on the network.

BIP-110's mechanics mirror the contested governance battles of the 2015–2017 Blocksize Wars, when participants debated whether raising the block size limit was worth the risk of a chain split. Under the proposal, activation would require support from 55% of Bitcoin validating nodes across a defined block "period." During period 475, spanning blocks 955,584 to 957,599, just 1% of blocks signaled support for BIP-110. The proposal includes a one-year temporary limit on non-financial transactions, a structure its authors argue would not produce a permanent chain split.

The dispute comes as Ordinals activity has fallen sharply. Fewer than 10,000 inscriptions have been recorded on the Bitcoin blockchain daily over the past month, down from a peak of more than 400,000 in August 2023, according to Dune Analytics data. Back, whose company Blockstream is a major $BTC infrastructure provider, described BIP-110 as a "quest to police other people," arguing that Bitcoin's decentralization and cypherpunk ethos require that "you can't impose your views on others." Dashjr and other proponents have labeled Ordinals-driven blockchain bloat a "serious threat," while maintaining that the temporary fork would not invalidate fee-paying transactions over the long term.
