Bitcoin's BIP-110 Fork Freezes at 2 Blocks, but the 55% Warning Stays Real

BIP-110's immediate split risk faded, but the signaling test still matters for BTC

The short-term split risk has eased. The BIP-110 side has been frozen at block 961,632 while the main chain kept producing blocks 961,633 and 961,634. Mechanically, that makes the fork itself a short-term non-event: the rival chain failed to extend, and the rest of the network kept building.

Miner support still looks too weak for a clean bullish case

The pressure point is no longer whether the split survived. It is whether BIP-110 can gain credibility before the signaling window closes. Right now, miner support is seldom exceeding 2.5%, well below the 55% signaling threshold. That does not look like the trajectory of a proposal with confident backing.

The calendar still matters more than the stalled fork

BIP-110 locks in no later than block 963,648 in late August and activates its new transaction rules at block 965,664. With that window now open, the main risk is less a lasting chain split than a hit to confidence if another near-miss leaves traders questioning network cohesion.

The first market pressure from BIP-110 is likely confidence, not permanent breakage

The stall reduced immediate breakage risk, but it did not remove the broader narrative risk.

Sentiment can react to divided signaling even without a lasting split

The key question is not whether BIP-110 is good policy. It is whether divided signaling makes markets treat Bitcoin as a noisier, less predictable settlement asset. The proposal still carries a 55 percent miner-signaling threshold, yet support has been seldom exceeding 2.5%. That gap matters because it keeps uncertainty alive around whether a future rule change is coming.

A proposal with such thin backing is easier for bears to frame as evidence of internal friction than as a clean coordination success. That narrative does not require a lasting split to pressure sentiment.

Miner economics look limited, but coordination costs are harder to ignore

Miners may not lose much from disputed transactions on pure fee terms. One Reddit estimate says those transactions represent about 0.1% to 0.2% of miner revenue. But the real question is what miners do when rule enforcement starts to clash.

The early split already showed the pressure point. BIP-110 mined only two blocks before stalling, while the main chain kept running. Observers also noted extremely divergent block templates across the split. If that confusion persists deeper into the signaling window, miners face a tougher trade-off: follow a rule set with weak support, or ignore it and risk reputational backlash from backers. That is not just a revenue decision.

Custody and operational friction are the sharper investor concern

For investors, the more concrete risk is operational friction at exchanges and custodians. Bitcoin's rules have been stable since Taproot activated in November 2021, so a new contested rule change revives basic questions about which chain should be treated as authoritative during activation.

That is why the market cost can exceed the technical cost. A protocol debate can translate into slower deposit or withdrawal processing, tighter custody practices, or other liquidity friction. If BIP-110 stays this weak, activation risk remains limited. But as long as the debate is live, BTC can still absorb a sentiment tax.

BTC trade setup: constructive unless signaling improves or the chain splits again

Trade BTC as a reaction setup, not a panic setup. BIP-110 still sits at just 2.6% support against a 55% signaling threshold, which is not itself a market-resetting level.

• Watchpoint: If support stays weak and another stall repeats, the constructive read remains intact.
• Invalidation: If miner support moves sharply higher before lock-in, or if a second split produces meaningful extension on the rival chain, the risk case strengthens.
