Bitcoin backers Michael Saylor and Adam Back oppose BIP-110

Their pushback comes as Ordinals inscriptions have fallen to under 10,000 per day in recent weeks, from more than 400,000 at the August 2023 peak.

Bitcoin bulls Michael Saylor and Blockstream CEO Adam Back are doubling down against BIP-110, a proposed temporary fork that would limit non-monetary transactions and other arbitrary data on the Bitcoin network. Cointelegraph reports that the proposal, introduced in December 2025, is aimed at reducing “spam” from Ordinals inscriptions while preserving Bitcoin’s use as peer-to-peer cash.

Saylor said BIP-110 could do more harm than good, warning in a post on X that it could invalidate ordinary transactions and arguing that there are “110 things more dangerous to Bitcoin than spam.” Cointelegraph also notes that Back shares concerns that a fork could damage Bitcoin’s credibility.

Cointelegraph frames the debate as one of the more notable protocol disputes since earlier “Blocksize Wars” era discussions about whether a chain split was worth the risk to improve scalability. The article says BIP-110 was put forward by pseudonymous developer “Dathon Ohm,” with support from Ocean protocol founder Luke Dashjr.

Cointelegraph adds that Ordinals activity has dropped sharply, with fewer than 10,000 inscriptions into the Bitcoin blockchain per day over the last month, down from more than 400,000 at the peak in August 2023. It also says that during a recent period, only about 1% of blocks were BIP-110 supportive between block 955,584 and 957,599.
