BIP-110 Fork Fails: Who Has the Right to Change Bitcoin?

TL;DR

BIP-110 sought to raise the cost of writing large volumes of contiguous data — Ordinals inscriptions and the like — through a temporary consensus restriction.
In the voluntary early-lock-in phase, the proposal drew signals from only 51 blocks — 2.53% support — far below the 55% threshold.
Once the mandatory signaling period began, the minority chain formed by supporters produced just two blocks before stalling; BIP-110 is effectively dead as a network-wide consensus upgrade.
The debate over on-chain data, protocol neutrality, and development governance will continue; and because the forked chain lacks replay protection, ordinary holders should not rush to move or trade related assets.

In the early hours of August 9, Beijing time, Bitcoin reached block height 961,632 and BIP-110 entered its mandatory signaling period. Nodes running BIP-110 rules began rejecting blocks without version bit 4 set, splitting off from the mainnet. Thereafter, the BIP-110 branch produced only two blocks before stalling, while the mainnet kept producing normally. Over the preceding difficulty-adjustment period, only 51 blocks had signaled support — 2.53% — far below the proposal’s 55% voluntary early-lock-in threshold. BIP-110 thus never won broad miner support, and ultimately formed a minority chain with negligible hashpower.
