Foundry polls miners on BIP-110 as Adam Back says support is too low

Foundry USA Pool has begun surveying mining clients on whether to support BIP-110, a proposed Bitcoin soft fork that would temporarily restrict arbitrary non-monetary data and several currently valid transaction features. Foundry said voting is weighted by each client’s average 10-day hashrate from July 6 to July 15, with polling starting July 16; the pool will keep signaling “No” unless more than 51% of voting hashrate supports switching to “Yes,” and non-votes count as “No.” The proposal faces criticism from prominent industry figures. On July 18, 2026, Blockstream CEO Adam Back said BIP-110 is likely to fail, citing signaling data showing only 0.86% support in the current difficulty period, far below the 55% threshold needed for lock-in as mandatory signaling approaches near block 961,632. Strategy founder Michael Saylor published a detailed critique including “110 reasons” to reject the proposal, arguing it would use consensus rules to invalidate some currently valid, fee-paying transactions, bundle seven temporary restrictions into one package and create precedent and activation risks. Saylor also said many Bitcoin supporters he respects back BIP-110 and that he understands their desire to protect Bitcoin, but called the proposal’s solution “more dangerous than the problem itself” and said he will present “110 reasons” Bitcoin must uphold neutrality as a global open, decentralized monetary network. He has also argued Bitcoin should uphold neutrality, open markets and permissionless innovation, and that Bitcoin cannot judge transaction intent or use cases, so disputed activity such as inscriptions should be addressed by market forces, relay policies, mining policies and node operators rather than the protocol. F2Pool co-founder Wang Chun also said F2Pool will not support BIP-110.
