Bitcoin's BIP-110 is stalling. The market isn't flinching.

BIP-110, the user-activated soft fork designed to tighten Bitcoin Core's relay policy, has produced two blocks in roughly a day of mandatory signaling and has not budged past the network's full mining difficulty. Reporting on 9 August 2026 put the enforcing chain still pinned to Bitcoin's regular schedule, with mandatory signaling proceeding on a sliver of hashpower (Cointelegraph). Bitcoin itself, by contrast, sat within touching distance of $65,000 on the same day, with spot-ETF inflows offsetting the headline risk (Investing.com). The market is doing something unusual with this fork: ignoring it.

The read for the rest of the year is that protocol politics are increasingly a separate game from price action. BIP-110 was always designed to advance regardless of miner sentiment. With activation on track and the hashpower deficit now public, the contest is over whether an enforcement fallback kicks in. Volatility traders have already priced that as a low-conviction event.

Two blocks, no separation

The proposal crossed its mandatory-signaling milestone around 8 August 2026, with on-chain data showing less than 3% of miner support behind the change (Cointelegraph, 8 August). Block 961,632 was the marker, and influential commentators had already publicly opposed the fork before activation (CoinDesk, 8 August). Two days later, the enforcing chain remained "stuck" at Bitcoin's full mining difficulty, unable to push its own epoch forward without a critical mass of hashpower behind it (Cointelegraph, 9 August). The mechanism is doing what the mechanism was designed to do: it advances on user-activated signaling rather than miner signalling, so the absence of miner support does not by itself kill the proposal (CoinDesk, 7 August). What it does is force a conversation about the fallback. A hard fork, an enforced difficulty override, or quiet deprecation are all on the table, and developers are publicly advising holders to do nothing until the two chains can be cleanly separated (CoinDesk, 8 August, on replay risk).

The replay warning is the operational point that matters for anyone with non-custodial bitcoin. If a minority chain emerges this weekend, any signed transaction spending fork-coin could be replayed on main-chain bitcoin, debiting real BTC from the same wallet. The safest posture, on the developer framing, is to refrain from moving fork-coin until an explicit replay protection mechanism is live.

Volatility says nothing matters; options traders disagree

Bitcoin's BVIV index printed its lowest reading since 2025 over the weekend of 9 August, with the option book showing an outright collapse in demand (CoinDesk, 10 August). That is the surface read: implied vol is at a year-and-a-bit low, the term structure has flattened, and day-to-day price action has stopped surprising anyone. Underneath the calm, overwriting surged and downside protection still commands a premium over calls at the same strike. In plain terms, professional vol traders are selling upside while keeping their insurance against a tail. That is a hedged-bearish posture, not a bullish one, even though the price line has stopped cooperating with it.

The ETF tape is the other side of the same story. Bitcoin slipped below $65,000 on 9 August and recovered on inflows that the cited wire reporting characterised as offsetting the fork risk (Investing.com). A day earlier, the same outlet had framed a push back toward $65,000 against a separate set of infrastructure-security concerns, suggesting the tape is taking its cues from custody and flow rather than from protocol governance (Investing.com, 8 August). The fork is, in effect, a non-event for the spot price.

What the fork fight actually tests

BIP-110 is a policy fork, not a consensus fork. It targets relay rules around transaction filters and is being run through a user-activated pathway precisely because the miners have not signed off. That is the test case: whether a sufficiently motivated node-and-end-user coalition can move Bitcoin's de facto policy without miner consent. The precedent matters because the next round of policy disputes, from mempool rules to block-construction guidance, will run through the same playbook.

Monexus assessment: the more interesting read is not whether BIP-110 activates on its current schedule, but what the fallback choice tells the market about governance tolerance. A clean hard fork with replay protection is one outcome; a quiet abandonment is another. The first signals that policy-forcing is a viable tool, the second that it isn't.

Stakes and the next 72 hours

For miners, the immediate stake is revenue. A minority chain with near-zero hashpower is unprofitable to mine, and the equipment that flips across is mining at a loss against an electricity bill. For exchanges and custodians, the operational burden is replay protection, balance-sheet segregation, and a customer-facing decision about which chain gets the ticker. For holders, the practical advice is the boring one: do not move fork-coin until the chains can be distinguished. For the broader market, the read is that a contested soft fork no longer moves spot price, and that vol traders are paid to hedge that fact rather than to fight it. The fork fight is a governance stress test; the price tape has decided it is not a market event. Monexus will be watching whether the fallback choice, when it comes, changes that read.

Desk note: this piece treats the fork as a governance story priced into a low-vol regime, rather than as a directional catalyst. Wire reporting has framed BIP-110 in protocol terms; we frame it in flow and posture terms and flag the replay risk separately.
