At 6:34 a.m. UTC on Aug. 9, Bitcoin existed in two states. One chain, the dominant proof-of-work ledger, stood at block 961,690. The other, a two-block ghost chain enforcing BIP-110, sat 57 blocks behind at 961,633. Its latest block was nearly nine hours old. This is not a reorg. This is a consensus split—a temporary soft fork that entered its mandatory signaling window and immediately produced a measurable minority branch. But the data tells a deeper story: the enforcing chain has been silently boycotted by the mining majority. Over the first 59 blocks of the window, zero carried the required version bit 4 signal on the dominant chain. Only OCEAN pool contributed to the fork, producing two blocks at heights 961,632 and 961,633. The rest? Foundry, F2Pool, AntPool, ViaBTC, MARA—all stayed on the main chain. Chasing the ghost in the smart contract code, I traced the headers. The pattern is stark.
BIP-110 proposes temporary consensus limits on methods of placing arbitrary data in Bitcoin transactions—a spam filter, essentially. Its deployment uses a 55% threshold (1,109 of 2,016 blocks) and requires signaling from heights 961,632 through 963,647 for enforcing nodes. If an enforcing chain reaches height 963,648, it enters LOCKED_IN, and restrictions become ACTIVE at height 965,664. But the current split occurred during mandatory signaling—the transaction restrictions are two stages away. The proposal has been controversial since its introduction. Supporters argue it keeps Bitcoin focused on money; critics say filtering valid transactions weakens neutrality. Since May 1, miner signaling has hovered at 0.42%, per BGeometrics. The August lock-in window was supposed to force exchanges and pools to take a stand. Instead, the market delivered a verdict: silence. Based on my experience auditing signaling mechanisms during the 2022 Terra collapse—where on-chain data revealed the depeg minutes before exchanges halted withdrawals—I know that silence in mining is rarely neutral. It is a signal in itself.
The divergence began at height 961,632. Enforcing nodes started rejecting blocks without version bit 4. I reviewed the dominant chain’s first 59 block headers in the window. Result: zero bit-4 signals. The BIP-110 enforcing branch produced two blocks, both attributed to OCEAN. Then, nothing. For enforcing nodes, this is a consensus split—they are on a minority chain that cannot advance without more hashpower. Meanwhile, the dominant chain continued adding blocks at a normal pace. Pool attribution is coinbase-based and does not establish formal policy, but the pattern is clear: major pools have not switched. Foundry, F2Pool, AntPool, ViaBTC, MARA all appear on the dominant branch. No observable major-pool switch after the window opened. This is not a technical failure; it is an economic boycott. Miners are rationally choosing the chain with higher probability of finality. The two-block branch is orphaned in all but name. Exchange status feeds from Coinbase and Kraken reported Bitcoin operations normal. Wallets, merchants, and self-hosted nodes remain outside the sample. At the snapshot, 1,957 blocks remained in the signaling window. The zero-of-59 result establishes a clear absence of dominant-chain signaling. Follow the scholar, not the token—the miners are voting with their hashpower, not their version bits. The chart didn't lie: the enforcing chain is a ghost.
The popular narrative frames this as a 'silent miner boycott'—ideological opposition to BIP-110. But I see a different mechanism at work. This is not about ideology; it is about risk management. Miners operate on thin margins. Switching to an enforcing branch risks orphan blocks and lost revenue. The two-block branch is not being boycotted; it is being ignored because it offers no economic incentive to join. The real story is that BIP-110's threshold of 55% was always a paper target. In practice, soft forks require overwhelming hashpower support to avoid splits. The enforcing nodes—likely a small group of ideologically committed operators—are now stuck on a chain that cannot grow. Beneath the surface, the nest was empty. The silent boycott is not a protest; it is a rational market response. If no major pool switches in the next 1,957 blocks, BIP-110 will fail to reach LOCKED_IN. The proposal will die not by vote, but by indifference.
Watch the next 1,957 blocks. If Foundry or AntPool flips a bit, the fork becomes a real contest. If not, BIP-110 becomes a textbook case of economic consensus overriding protocol rules. Speed eats stability for breakfast—but in this case, stability ate speed. The enforcing chain raced ahead and found itself alone. The market has spoken. Now we wait to see if anyone listens.
