Miners reject BIP-110 proposal after two blocks

A proposed Bitcoin upgrade known as BIP-110 has stalled after mining only two blocks, with its enforcing fork stuck at Bitcoin’s full mining difficulty and almost no hash power signaling support.

BIP-110 is a technical proposal designed to change how Bitcoin handles block size limits by letting miners vote on temporary increases. It emerged as Bitcoin’s block space grows scarce, pushing fees higher and slowing transactions. Proponents argue it buys time for deeper consensus on long-term scaling solutions. But the approach has drawn criticism for centralizing control and delaying a full block size debate.

The fork’s difficulty remains locked at Bitcoin’s baseline, meaning miners aren’t committing real hash power to secure the chain. Only a handful of test blocks have been mined, far below the 95% threshold needed for activation. Core developers and mining pools have largely ignored or opposed BIP-110, favoring alternative roadmaps like SegWit and later Taproot upgrades.

If the fork fails to gain traction, Bitcoin’s transaction backlog may worsen during high-demand periods, reinforcing calls for clearer scaling plans. Without wider miner support, BIP-110 risks fading into obscurity, leaving Bitcoin’s capacity debate unresolved — again.
