Bitcoin's BIP-110 fork stalls as hashpower stays home; BTC holds above $65,000 into US data week

Block 961,632 landed on the Bitcoin network on 8 August 2026, and with it the start of mandatory signaling for BIP-110, a proposed soft fork aimed at tightening rules around the OP_RETURN data field. Within twenty-four hours the enforcing branch had produced just two blocks, while miner support sat below 3% of hashpower (CoinDesk, 8 August 2026; Cointelegraph, 8 August 2026).

By 10 August 2026, Bitcoin trades above $65,000, with spot ETF inflows absorbing the supply fork uncertainty typically releases and a quieter macro tape clearing space for a quiet rally ahead of US inflation data due this week (Investing.com, 10 August 2026; CoinDesk, 10 August 2026). The split between chain-level politics and price action is the story.

The fork that won't unstick

BIP-110 is a user-activated soft fork, which means it does not need miner supermajority to lock in. Enforcing nodes can move the network's rules forward unilaterally. That design choice is precisely why the proposal has lingered through repeated rounds of indifference from miners. A Cointelegraph brief on 9 August 2026 put the gap plainly: "The enforcing fork remains stuck at Bitcoin's full mining difficulty as mandatory signaling proceeds with little hashpower support."

For ordinary holders, the practical risk is replay. A developer quoted by CoinDesk on 8 August 2026 warned that anyone who spends coins on a minority fork branch between now and chain separation risks having that signed transaction replayed on the dominant Bitcoin chain, paying out real BTC for what was intended as fork-coin. The safest path, the developer argued, is to do nothing until the chains can be cleanly distinguished. The same reporting flagged a secondary path: a hard fork of the enforcing side, the kind of clean break the BIP-110 design was explicitly built to avoid.

The thread evidence supports a continuing-but-stalled read. CoinDesk's 7 August 2026 explainer framed it as a proposal "attracting only a sliver of miner support, yet its user-activated design means the proposal continues toward its activation date and (most likely) beyond." External reporting cited elsewhere has described the effort as failed or dead, which is a materially different framing; on the available thread evidence the more defensible characterisation is that mandatory signaling is live, miner adoption is negligible, and the proposal's design lets it keep advancing regardless. Which read becomes the dominant one will turn on hashpower movements and venue posture over the next several days.

The price ignores the noise

While the chain politics have stalled, the order book has rallied. Bitcoin slipped below $65,000 on 9 August (per the Investing.com headline of that date), then climbed back above it by 10 August (Investing.com, 10 August 2026; CoinDesk, 10 August 2026), a swing consistent with ETF demand absorbing the supply that fork-driven uncertainty typically releases. CoinDesk's 10 August market note flagged that every major except XRP was green on the week, with BTC, ether and BNB each up nearly 3%, and global equities trading near records.

The volatility picture supports that read. CoinDesk's day-ahead brief on 7 August 2026 ran the headline "Bitcoin's volatility has nearly disappeared. The risk hasn't." Implied vol is compressed; tail risk from a fork misstep, a hostile macro print, or a sudden liquidity event is not. The market is paying for peace; it is not insured against surprise.

Why a fork with no miners still moves

BIP-110's refusal to die despite near-zero miner support is the more interesting structural fact (CoinDesk, 7 August 2026). User-activated soft forks invert the usual veto: miners can refuse to enforce, but they cannot stop enforcing nodes from rejecting their blocks. The proposal has attracted only a sliver of hashpower, yet its design means it continues toward activation regardless.

Monexus analysis: this is governance by infrastructure, not governance by capital. The constituency that decides what Bitcoin is has shifted, at least for this one rule change, from those who spend on electricity to those who run the validating software. Mining pools, by contrast, retain an economic veto: they can simply decline to mine on top of the new rules, fragmenting hashpower but not the protocol.

The fork is therefore best read not as a coming split but as a referendum on who sets the rules. If BIP-110 activates cleanly with under 3% miner support, the precedent travels. The next contested change will not need a mining consortium to win; it will need a critical mass of node operators, exchanges, and wallet vendors to coordinate. That is a meaningfully different political economy from the one Bitcoin has operated under since the blocksize war.

What to watch into the data week

The market's immediate focus is the US inflation print expected this week, with Iran-related risk headlines running alongside as a secondary driver (Investing.com, 10 August 2026; CoinDesk, 10 August 2026). A softer number extends the risk-on tape that has carried BTC back through $65,000; a hotter number pulls the macro argument in the other direction.

On the fork, two markers matter more than price. First, hashpower on the enforcing side over the coming days: if it climbs materially above 3%, BIP-110 has a real chance of a clean activation; if it stays where it is, the proposal's user-activated design continues to carry it forward but with the legitimacy gap widening (Cointelegraph, 9 August 2026). Second, exchange and wallet posture: which venues announce replay protection, and when. That is the operational signal holders should care about more than the headline price.

The fork is small, the price action is real, and the precedent, if it lands, is durable.

This piece focuses on chain-level governance and the immediate macro tape. The sources do not specify which wallet vendors or exchanges have announced replay-protection measures, and we have not independently verified any venue's posture beyond the developer warnings cited above. External outlets have characterised the fork in stronger terms than the available thread evidence supports; readers should weight the continuing-but-stalled framing as the thread's read rather than a settled verdict.
