Bitcoin BIP-110 moves to mandatory signaling as miner support stays under 3%
The latest deployment milestone for BIP-110 tests whether enforcing nodes can operate with minimal miner signaling, while developers consider a hard-fork fallback.

Bitcoin Improvement Proposal 110 (BIP‑110) has entered the mandatory signaling phase, a step that requires full nodes to enforce the proposed rule regardless of miner vote. Current miner signaling for the change remains below three percent.
The milestone obliges enforcing nodes to sustain the protocol alteration, effectively testing the network’s ability to operate under the new requirement despite limited miner endorsement.
With miner support at such a low level, developers are discussing a potential hard‑fork fallback that could be triggered if the mandatory signaling does not achieve broader consensus.
The outcome will inform whether the Bitcoin network can maintain stability while advancing protocol upgrades in an environment of minimal miner participation.
