BIP-110 Signaling Starts With 2.5% Miner Support Amid Saylor Back Opposition

Woofun AI reports that Bitcoin reached block 961,632, triggering the mandatory signaling period for BIP-110, a controversial proposal aimed at curbing non-financial data embedding. This activation phase has immediately drawn sharp opposition from Strategy chairman Michael Saylor and Blockstream CEO Adam Back, setting the stage for a contentious governance battle.

The signaling window opened at approximately 19:35 UTC on Saturday, yet miner support remains stagnant below 2.5%, far short of the 55% threshold required for standard activation. Per Woofun AI, this lack of consensus has prompted proponents to pivot toward a user-activated soft fork (UASF) model, bypassing miner approval entirely. This strategic shift relies on node operators to enforce the rule change, effectively attempting to coerce miners into compliance or exclude them from the network.

Proponents cite the 2017 activation of SegWit via BIP-148 as historical precedent for this approach, where users accepted the upgrade despite insufficient miner support. Under the UASF mechanism, users would update their node software to reject blocks from miners who fail to signal support for BIP-110. This creates a direct conflict between the mining sector, which controls hash power, and node operators, who define network validity.

The immediate consequence is the potential emergence of two competing Bitcoin networks: a dominant mainnet backed by most hash power and institutional capital, and a minority chain enforced by BIP-110 nodes. This split could persist until block 965,664, expected in about four weeks, leaving the network's future structure uncertain. This marks a critical test of user versus miner authority in Bitcoin's governance.
