Why BIP-110 Failed: Flawed Soft Fork Design or Miner Capture?

A Fracture in Node Sovereignty

In the wake of the now-failed attempt to restrict non-financial data on the Bitcoin blockchain, prominent ecosystem voices, including BIP-110 proponent “Bitcoin Mechanic,” have declared that the protocol has suffered terminal “protocol capture” by centralized mining cartels.

The fallout follows the Aug. 8 activation deadline for BIP-110, yielding barely 2.5% hash power support. Nodes enforcing BIP-110 automatically split from the main network at block height 961632, causing a brief chain split that brought the minority chain to an immediate halt.

In a recent lengthy post on X, Bitcoin Mechanic—writing in an individual capacity separate from his association with OCEAN Mining—said the event has shattered his faith in Bitcoin’s governance model and node-level sovereignty. For years, a central tenet of Bitcoin philosophy held that decentralized full nodes, run by individual users, hold ultimate authority over the network’s consensus rules, serving as a check against miner overreach.

However, according to Bitcoin Mechanic, the rejection of BIP-110 by major pool operators proves that the dynamic no longer exists.

“This shattered a long-standing belief that Bitcoin’s anti-fragility and hard-monetary properties would continue thanks to its decentralized network of nodes who were run by people who understood Bitcoin and would fight to preserve it,” he wrote. “Proof-of-work is completely pointless if the criteria for what constitutes validity is decided by the ones doing the work.”

He accused major mining pool operators of acting as a “small cartel” operating behind closed doors to protect corporate interests, effectively overruling public community sentiment. He warned that the ongoing “dollarization” of the ecosystem will push Bitcoin away from its founding goal and transform it into a centralized tool for corporate and state alignment.

Stalled Chains and the Looming Algorithm Change

The technical consequences of the failed soft fork are already playing out. Because nodes running software built to enforce BIP-110—such as customized instances of Bitcoin Knots—refuse to accept blocks from the main chain that violate the new data-filtering rules, those nodes are now functionally isolated from the live Bitcoin network.

With the minority chain possessing less than 3% of total global hash power, block production on the BIP-110 chain has collapsed.

“My entire Bitcoin stack sees as the state of the network… simply stuck at block 961,633,” he noted, estimating that at current hash rate levels, producing blocks under the old proof-of-work (PoW) algorithm would take upwards of 32 hours per block.

Facing a chain frozen by difficulty adjustments that could take years to resolve naturally, some BIP-110 supporters are now weighing a drastic technical response: changing Bitcoin’s underlying PoW algorithm to strip current ASIC miners of their power.

Bitcoin Mechanic stated he fully supports a hard fork to a new PoW algorithm, arguing it represents the only logical defense when physical mining power becomes too centralized. He indicated he plans to keep his node paused until an upcoming Bitcoin Knots update implements a new algorithm capable of restoring block production.

However, he expressed no interest in fighting a brand war over the “Bitcoin” name.

“I have no desire to attempt to call this new chain ‘Bitcoin’ — Bitcoin is a case study in protocol capture and instead of dying, becomes a tool for the sickest of purposes,” he concluded. “I can think of nothing more evil than centralized Bitcoin.”

Industry Voices Push Back: Governance or Flawed Design?

While advocates like Bitcoin Mechanic view BIP-110’s failure as proof of miner capture, other industry figures argue the outcome simply demonstrates Bitcoin’s built-in defense mechanisms operating as intended.

Leo Fan, founder and CEO of zero-knowledge infrastructure provider Cysic, rejected the narrative that a single group dictates network rules, framing the difficulty adjustment and low support as structural realities rather than outright subversion.

“Bitcoin’s difficulty rules protect the incumbent chain from low-hash forks. Minority chains remain possible, but they must secure enough hashpower, or openly redesign themselves as separate networks,” Fan explained.

Addressing the balance of power, Fan emphasized that authority remains distributed across multiple facets of the ecosystem: “Nodes choose which rules to enforce, miners determine whether a chain keeps producing blocks, and exchanges and users determine which chain retains liquidity and the Bitcoin identity.”

Fan identified the proposal’s mandatory activation design as its primary flaw. With signaling hovering near 2.5%, forcing mandatory enforcement guaranteed a split and an immediate chain stall. “Activation thresholds should confirm consensus, not manufacture it,” Fan told Bitcoin.com News. “Single-digit support should trigger withdrawal or redesign, not automatic enforcement… The real problem was that major pools and their miners were unconvinced. Their non-signaling was the verdict, not the root cause.”

The anonymous owner of 1win echoed similar sentiments, arguing that the stalled BIP-110 chain is evidence of protocol resilience rather than systemic failure.

“BIP-110 didn’t fail because of a single actor or a social media debate. It failed because it never achieved the level of consensus required to change Bitcoin,” the 1win owner stated. “Miners signaled just 2.53% against a 55% activation threshold. That number alone shows the proposal never gained meaningful traction across the ecosystem.”

Addressing criticism surrounding the difficulty adjustment, the owner countered that the mechanism is designed to prevent minority factions from easily fracturing the network without substantial market backing:

“Once the BIP-110 chain split off, it inherited Bitcoin’s full mining difficulty but attracted only a tiny share of the network’s hashpower. That mismatch is what stalled it… Bitcoin deliberately makes contentious forks economically expensive unless they are backed by substantial hashpower and broad coordination.”

From a governance standpoint, the 1win owner noted that the episode proves technical proposals require holistic alignment across miners, node operators, exchanges, custodians, and economic users before activation mechanisms are triggered.

“The real issue was that the largest mining pools, including Foundry, AntPool, ViaBTC, and F2Pool, never supported the proposal at all,” the 1win owner concluded. “Bitcoin’s governance model rewards patient coordination… Here, Bitcoin worked exactly as designed — slow, conservative, resistant to unilateral change.”

As the main Bitcoin chain continues uninterrupted, the departure of vocal hardliners toward a brand-new PoW chain highlights a deepening ideological rift within the ecosystem—one that pits institutional scaling and miner neutrality against radical node sovereignty.
