A Bitcoin branch tied to BIP-110 stalled after producing only two blocks, according to CoinDesk. The contested fork mined a short chain before it ceased advancing, signaling insufficient sustained hashpower rather than any disruption to the main Bitcoin network.

The proposal is documented in BIP-110's specification on the Bitcoin BIPs repository, the canonical reference for the intended rule change. A BIP itself defines a proposed modification; a live branch only materializes when miners actually construct blocks under those rules. BIP-110 reached its third activation stage, but only briefly.

This distinction is critical: a BIP is a proposal, activation support is gauged through miner signaling, and a branch is the physical chain of blocks that emerges when sufficient hashpower enforces the new rules. Bitcoin's proof-of-work design means any chain without continuous hashpower backing is mathematically guaranteed to fall behind the main chain, since blocks arrive roughly every ten minutes and the longest valid chain is treated as authoritative.

Why Two Blocks Signals a Support Deficit

Two blocks suffice to demonstrate that the proposed rules can produce a valid chain, but fall far short of sustaining one. Without continuous miner participation, a branch cannot keep pace with the main chain and simply stops extending.

The stall aligns with earlier indicators of thin backing. As previously reported, BIP-110 had entered mandatory signaling with miner support below 3% — a level well beneath what a durable branch requires.

The proposal's status has been tracked at the BIP-110 project site, and competing chain tips can be observed through public monitoring tools such as Fork.observer, which visualizes branches as they appear and are subsequently abandoned.

Implications for Bitcoin Holders

For ordinary Bitcoin users, a branch that halts after two blocks requires no action. The main chain continued operating normally, and a short-lived branch does not split balances or compel holders to choose sides.

The episode serves primarily as a signal about ecosystem backing. A change that cannot retain miner support beyond two blocks illustrates that a proposal can be technically valid yet still lack the economic weight needed to become a competing chain. Bitcoin's upgrade process has historically set a high bar for contentious changes — previous proposals that failed to reach sustained consensus, such as those advancing larger block sizes, similarly demonstrated that miner and ecosystem alignment, not technical merit alone, determines whether a branch endures.

This outcome establishes a reference point for future fork and upgrade campaigns. Contentious changes will likely be measured against the same threshold BIP-110 failed to clear: whether they can attract and sustain enough hashpower to keep a chain alive beyond its initial blocks.
