BIP-110 is technically live and politically orphaned. Bitcoin's price doesn't seem to mind.

Bitcoin block 961,632 was mined at roughly 20:06 UTC on 8 August 2026, and with it the network crossed the activation threshold for BIP-110, a controversial proposal that has spent months gathering users and losing miners in roughly equal measure. Two blocks later, the breakaway chain inherited bitcoin's full mining difficulty, then stalled for hours between finds because fewer than 3% of hashpower had bothered to signal support (Coindesk).

That gap, between a community of node operators that wants the change and an industrial mining base that plainly does not, is the story of the week. Spot bitcoin has spent the days since oscillating in a tight band around $64,000-$65,000, dipping below the round number on 9 August before reclaiming it on inflation expectations into 10 August. Traders are not pricing the fork as a tail risk; they are pricing the US Consumer Price Index print due later this week (Coindesk).

What BIP-110 actually does

BIP-110 is a user-activated soft fork. Its mechanism is the inverse of the playbook that brought miners SegWit and Taproot: rather than waiting for hashpower to cross a threshold and then locking in, BIP-110 sets an activation date and lets enforcing nodes carry the change on their own. Once block 961,632 passed, the rules tightened for any node running the BIP-110 software. Miners who never signalled the change are now mining what is, from their vantage, a non-BIP-110 chain that is fully compatible with the same transaction set (Cointelegraph).

That is the structural novelty, and the reason the proposal has refused to die despite near-zero mining support. The activation path does not require the constituency that produces blocks; it requires the constituency that validates them. The Coindesk explainer from 7 August walked through why the design effectively lets the proposal walk past gatekeepers who have refused to move (Coindesk).

Why miners aren't following

The mining industry's position has hardened into a near-uniform no. Influential commentary against the proposal had already been circulating in the run-up to activation, and the hashpower that bothered to signal stayed below the 3% mark by 20:06 UTC on 8 August (Coindesk). Two blocks mined on the BIP-110 chain over the following hours ran into the difficulty inheritance problem that minority forks always run into: the same target difficulty as the parent chain, but a fraction of the hashpower, means blocks arrive hours apart instead of every ten minutes (Coindesk).

The post-fork state at the time of writing is a slow chain. Both chains still accept the same transactions, which is the part that matters for ordinary holders.

What this means for anyone holding BTC

The risk that surfaced over the weekend is not a price risk; it is a replay risk. A developer quoted by Coindesk on 8 August warned that holders who sell coins received on a minority BIP-110 chain could find those same signed transactions replayable on the main bitcoin network, meaning an apparent sale of worthless fork coins could move real BTC (Coindesk). The defensive posture is to do nothing until the chains can be cleanly separated.

For traders, the price action tells a simpler story. Spot BTC slipped below $65,000 on 9 August as ETF inflows into US spot products offset fork-related caution (Investing.com). By the Asia session on 10 August, the complex had recovered, with BTC, ether and BNB each up close to 3% on the week while XRP lagged (Coindesk). Realised volatility has compressed to the point that one Coindesk daybook noted the disappearance of swings more than their presence (Coindesk).

What to watch next

Three data points will determine whether this stays a technical curiosity or becomes a market event.

First, the US CPI print expected this week. A soft print supports the rate-cut path that has been the dominant tailwind for risk assets through August; a hot print likely pulls BTC back under $64,000 and tightens the trading range further (Coindesk, Investing.com).

Second, whether BIP-110's enforcing chain attracts any incremental hashpower. The Coindesk account from 9 August described the breakaway chain as stuck at the inherited difficulty; any meaningful migration of miners would change the calculation, but none has shown up in the available source material (Coindesk).

Third, whether node operators consolidate around the change or quietly peel off. The Cointelegraph reporting on 9 August framed the situation as the enforcing fork still moving toward activation regardless of miner posture, which leaves the proposal's long-run viability tied to node count rather than hashpower (Cointelegraph).

Monexus assessment: the dominant wire framing treats BIP-110 as a governance stress test that markets have already looked through. The counter-read, which the available sources do not refute, is that a chain splitting off with sub-3% hashpower and a replay surface still open is the kind of structural risk that does not show up in spot price until it does. Holders with exposure on custodians that have not pre-announced replay protection are running that risk implicitly. The next 72 hours are less about the fork itself and more about whether miners, exchanges and major custodians issue coordinated guidance before any forced replay window opens.

Desk note: Monexus framed BIP-110 as a governance-versus-mining power struggle rather than the price drama that the wire has largely moved past. The piece treats node activation and hashpower signalling as separate constituencies, which the available reporting supports, and flags replay risk as the operational concern rather than treating the fork as resolved.
