BIP-110 Bitcoin Fork Stalls After Two Blocks Amid Limited Mining Support

A proposed Bitcoin fork, BIP-110, has stalled after only two blocks were produced on a minority branch. The fork began at block 961,632 when nodes enforcing the proposal started rejecting non-signaling blocks.

This rule divergence created a separate chain from the dominant Bitcoin network, but the enforcing branch struggled to maintain a regular block production schedule due to limited mining support.

Only 51 out of the previous 2,016 blocks signaled support for BIP-110, which is far below the proposed 55% threshold. The minority branch inherited Bitcoin's existing mining difficulty and received only a small fraction of its hash rate, making it unable to maintain the approximate 10-minute block interval.

The event has been described as a rule split and a real-time test of user-activated soft-fork coordination rather than a completed Bitcoin protocol upgrade. The proposed data restrictions have not yet entered the ACTIVE stage, but transactions may be valid on both chains without reliable replay protection.
