Core Overview

• The Bitcoin block height is about to reach 961632, at which point the BIP-110 proposal may limit non-financial data within transactions.
• Proponents of the proposal claim that this adjustment can return Bitcoin to its core function of settlement and alleviate the network burden caused by inscriptions and other applications that consume significant on-chain data.
• Critics warn that the proposal’s low voting threshold for miners and accompanying enforcement mechanism could likely lead to a split in the main chain, forcing major exchanges and node operators to adopt defensive measures.

Bitcoin is about to reach a critical point, as a years-long ideological divergence may evolve into the network’s most severe governance conflict in recent years. At the heart of this dispute is the Bitcoin Improvement Proposal BIP-110, which aims to limit the total amount of non-financial data that can be carried in Bitcoin transactions. The network is less than 10,000 blocks away from the mandatory activation window of block 961632, and this technical divergence, originally focused on "garbage transactions," has escalated into a high-stakes confrontation.

Supporters of BIP-110 believe that this limiting measure is the key to preserving Bitcoin’s core value as a currency settlement layer; opponents caution that this radical implementation risks splitting the entire industry ecosystem, leading to user assets being stuck in circulation while undermining market trust in the neutrality of the Bitcoin protocol.

Although the proposal has not yet garnered the broad support from miners and institutions required for significant protocol changes in the past, this impending contradiction will serve as a major stress test for Bitcoin’s decentralized power structure. The reason being that the proposal places network developers and node operators in opposition to miners and market makers, who are the core group that determines the economic value direction of the blockchain.

A Route Dispute Over Bitcoin’s Content Capacity

BIP-110 plans to temporarily limit any data storage on the Bitcoin chain by adding new consensus rules to the transaction structure. In simple terms, for nodes running the proposal code, transactions that carry massive amounts of data will be deemed invalid. The proposal targets inscriptions, runes, and other applications that directly engrave text, images, and token data onto the Bitcoin base chain.

These applications have indeed brought new users to the network and increased miner fee revenues, but they have also triggered frustration among Bitcoin purists who believe that the blockchain should not be used as a permanent storage medium.

Proponents define this change as a measure to maintain Bitcoin’s core functions. They argue that non-financial data consumes significant block space and burdens node operations, deviating from Bitcoin’s core position as a robust currency. In their view, filtering large data loads is not an audit of payment behavior but, rather, a restoration of rule boundaries, allowing the network to return to its original positioning.

This viewpoint has garnered support from a group of node operators and Bitcoin users who have long resisted the inscription craze. They believe that the upcoming activation window will prove that when users feel the Bitcoin rules are drifting from their original intent, the node holders responsible for verifying the entire chain still possess the ability to counterbalance miners and commercial entities.

Bitcoin analyst Luis Marcano, who supports the proposal, stated that the actual situation following BIP-110 activation may not be as dire as critics expect. He posits that nodes operating the new rules will reject blocks filled with irrelevant data, and computing power will ultimately flow to the blockchain that holds stronger economic value and complies with the new rules.

Some supporters take a firmer stance, depicting opponents as a small group of social media influencers, token investors, and enterprises profiting from on-chain data business. They claim that thousands of node operators are prepared to implement this new rule and that miners will not be willing to suffer the negative impacts of network uncertainty for the long term.

However, the market does not recognize this optimistic assessment.

Critics Warn: Proposal Implementation Mechanism Significantly Raises Conflict Risk

The most contentious aspect of BIP-110 lies in its execution design. In the past, large-scale protocol upgrades required miners, who maintain network security, to reach almost unanimous consensus before activation. However, BIP-110 completely changes this model: it only sets a 55% signaling threshold for miners and includes a highly controversial enforcement mechanism.

Even if miners fail to achieve the minimum voting threshold, supporters of the proposal plan to have all network nodes unilaterally reject any blocks not compliant with the new rules. This radical structure has transformed what was originally merely a technical divergence over block space allocation into a governance crisis at the foundational level.

Blockstream CEO Adam Back directly rejected this proposal, stating that it has serious technical flaws. He warned that forcing code changes without achieving economic consensus will almost inevitably create a forked chain with very few supporters.

Adam Back also explicitly opposed supporters analogizing this proposal to the 2017 SegWit upgrade. He stated that although there was considerable debate before the SegWit implementation, it ultimately gained broad consensus among developers, miners, and various infrastructure service providers, whereas the current BIP-110 lacks the same foundational industry consensus.

Veteran Bitcoin developer and security lead Jameson Lopp termed this proposal as dangerous overreach masquerading as governance of garbage transactions.

In addition to the immediate risk of chain splits, Jameson Lopp warned that this code could undermine the functionality of some niche wallets, potentially causing user assets to become inoperable. Furthermore, he believes that this limiting measure solves symptoms rather than root causes: Users with demand will simply switch other transaction fields to hide irrelevant data. Ultimately, Bitcoin will bear all systemic risks brought about by a controversial hard fork, without addressing the behavior that the proposal aims to curtail.

However, the fundamental disagreement that tears apart the entire industry ecosystem lies on the ideological level. The core value foundation of Bitcoin rests on absolute neutrality: as long as the sender pays fees that equate to market pricing, the network will process any compliant transaction.

Critics warn that actively punishing "unwanted" on-chain behavior through modifications to consensus rules will set an extremely dangerous precedent. If the protocol can filter inscription data today, other factions or national regulatory agencies may use this precedent in the future to demand the network block privacy coin transactions, gambling payments, or transfers containing politically sensitive information.

Supporters of the proposal dismiss these "slippery slope" concerns, stating that the network has always been able to distinguish between pure monetary use and the abuse of on-chain storage. They emphasize that BIP-110 is merely a precise adjustment, with the code explicitly setting an automatic expiration period of approximately one year.

However, this "temporary adjustment" explanation has done little to ease the opposing camp.

Bitcoin core developers, including Jameson Lopp, argue that a year-long rule change could cause damage exceeding that of a permanent change. Various enterprise wallets, cryptographic libraries, and smart contract protocols will need to build and maintain two sets of infrastructure to accommodate different rules.

More importantly, as a settlement network, Bitcoin heavily relies on stable and predictable rules, and a one-year temporary change will introduce long-term significant uncertainty. Developers cannot predict whether the restriction will simply expire, be extended, or be replaced with more stringent control rules.

The Market May Temporarily Downplay the Impact of BIP-110 Unless Exchanges Are Forced to Take Emergency Measures

Although rhetoric between core developers and node operators escalates, market analysts generally believe that the activation of nodes in early August will not trigger a catastrophic split in the network.

Bitfinex analysts, in their perspective provided to CryptoSlate, stated that the whole BIP-110 situation resembles a "governance stress test," rather than a true major crisis that would lead to chain splits.

This pragmatic assessment stems from the current obvious lack of economic consensus: currently, the proportion of nodes actively running the restrictive rules is only in the single digits, major mining pools are all taking a wait-and-see attitude, and the entire crypto industry shows no signs of urgently adjusting supportive systems or preparing to distinguish between two fork chains.

Various data indicates that the proposal is likely to fail to activate; in the worst-case scenario, it may only spawn a niche forked chain with very low liquidity and recognition.

In the history of the crypto market, there have been successful models to resolve such divergences. After the controversial fork that gave rise to Bitcoin Cash in 2017, liquidity, exchange support, and user groups quickly concentrated on the main chain that preserved the original economic scale and continued to use the BTC code designation.

Furthermore, the maturation of Bitcoin's market structure in recent years has provided a buffer space to mitigate the panic caused by protocol disputes. Unlike past cycles led by retail investors, today, the core forces influencing price trends are ongoing inflows from spot ETF funds, positions from professional derivatives institutions, and institutional allocation demands. In this mature market environment, a route dispute among a small group of developers is unlikely to trigger a long-term fundamental reassessment of asset prices.

The tail risk that truly needs to be monitored is concentrated on market infrastructure. If a group of nodes insisting on the new rules continues to support the niche fork chain during the activation window, centralized exchanges and asset custody institutions will have to initiate defensive plans.

To prevent replay attacks, ensure sufficient liquidity, and assess the overall stability of both chains, major trading platforms will likely temporarily suspend Bitcoin on-chain deposit and withdrawal operations.

For seasoned players in the crypto industry, such operations are not unfamiliar, but many new investors from traditional finance may struggle to adapt to the operational disruptions caused by decentralized consensus conflicts, which could easily trigger market emotional fluctuations.

In summary, BIP-110 currently lacks sufficient strong industry economic support to shake the status of the existing main chain. However, in the time leading up to the block height reaching 961632, the market is bound to experience short-term fluctuations driven by related news, the derivatives market will see a surge of hedging orders, and the entire industry’s institutional custody infrastructure will undergo a crucial stress test.
