BIP-110: A Clinical Dissection of Bitcoin's Failed Content Censorship Soft Fork
Hook
On the eve of its activation window, BIP-110 commanded exactly 1% miner support. That is not a typo. It is a statistical zero. The proposal to restrict Bitcoin’s data payload – framed as an anti-spam measure – died not from technical flaws, but from an immune response hardwired into the community’s DNA. But the autopsy reveals more than just a dead proposal. It exposes the fault lines in Bitcoin’s governance architecture and the mathematical inevitability of its rejection.
“Code does not lie, but it often omits the truth.” The omission here was the truth about miner incentives. BIP-110 was never a technical fix; it was a political coup attempt wrapped in a soft fork.
Context
BIP-110, officially the “Reduced Data Temporary Soft Fork,” was introduced in early 2024 as a response to the surge in non-monetary transactions on Bitcoin – specifically Ordinals inscriptions, BRC-20 tokens, and the Runes protocol. These applications bloated block space, driving up transaction fees and congesting the network for traditional value transfers. The proposal sought to temporarily limit block data to 1 MB per 10 minutes, effectively capping the amount of arbitrary data that could be included in witness and script fields.
Proponents, led by a small group of developers and miners, argued that Bitcoin was being degraded into a “digital landfill.” They proposed a reduced activation threshold of 55% miner signaling, rather than the historical 95% consensus required for soft forks. The stated goal was to pass the change quickly before ordinals cemented their presence.
Enter Michael Saylor, founder of Strategy (formerly MicroStrategy), holding over 84,000 BTC. He published a public statement warning that BIP-110 would “set a precedent for censorship” and risked a chain split. He was joined by Adam Back (Bitcoin core developer) and Jameson Lopp (Casa CTO), both labeling the proposal “reckless.” By mid-2024, only about 1% of miners had signaled support – a technical death sentence.
Core
The Engineering Anatomy of Failure
To understand why BIP-110 failed, we must dissect its three false premises.
Premise 1: Data volume is the root cause of congestion. Contrary to popular belief, Bitcoin’s block space is a scarce resource by design. The average block weight in early 2024 hovered around 1.2–1.5 MB (with SegWit discount). Ordinals added, at peak, an extra 200–300 KB per block. This is not structural congestion; it is cyclical demand. The real issue is fee market elasticity – users willing to pay higher fees for non-monetary uses crowd out lower-fee monetary transactions. BIP-110’s solution was to suppress demand, not increase supply. That is like treating a fever by breaking the thermometer.
Premise 2: A 55% threshold is sufficient for legitimacy. “Trust is a variable; verification is a constant.” Bitcoin’s 95% threshold exists for a reason: it ensures near-universal acceptance, minimizing the risk of a persistent chain split. With a 55% threshold, a coalition controlling just 56% of hashpower could force a soft fork on the remaining 44%. In hashpower distribution terms, that coalition could be formed by two large mining pools (e.g., Foundry USA and Antpool). If those two pools had coordinated, the fork would have been mandatory for all nodes under the new rules. Nodes running old clients would see blocks exceeding the data limit as invalid, effectively splitting the network.
Mathematically, the probability of a minority chain gaining economic significance under 55% activation is non-trivial. Using a simple Nash equilibrium model: if the minority holds 44% of hashpower and continues mining their own chain, they would produce blocks every ~13 minutes instead of 10. Their chain would lag but could persist indefinitely if economic nodes (exchanges, wallets) refused to upgrade. The result: two Bitcoins – a scenario that would destroy billions in market value.
Premise 3: Miners would benefit from reduced data. This is the killer flaw. Miners earn revenue from block subsidies (now 3.125 BTC per block post-halving) and transaction fees. BIP-110 would reduce fee revenue by eliminating high-fee ordinals transactions. A back-of-the-envelope calculation: in May 2024, ordinals-related fees accounted for 15–20% of total miner revenue. Removing that would hit miner margins directly. Why would miners support a proposal that cuts their income? They wouldn’t – unless they were compensated off-chain, which the proposal didn’t specify. The 1% signaling support was rational: self-interest aligned with network stability.
The Kill Switch: Conditions for Catastrophe
Every protocol upgrade should include a stress test. For BIP-110, the kill switch was embedded in its own design. The two main conditions for failure:
- Majority coalition consolidation: If two or three pools had colluded to signal 55%+, the risk of chain split would spike. The probability was low (given public opposition from leaders), but not zero. As a risk management consultant, I model worst-case scenarios. In a worst-case where Foundry (30% hashrate), Antpool (25%), and ViaBTC (12%) collectively signaled 67%, the fork would activate. The remaining pools (F2Pool, Binance Pool, etc.) would have faced an existential choice: follow or fork. That is not governance; it is hostage negotiation.
- Economic node fragmentation: Even if miners activated, exchanges and wallet providers would need to upgrade or risk accepting invalid blocks. A single major exchange refusing to upgrade could trigger a liquidity crisis. In 2026, we have seen how exchange concentration amplifies systemic risk. BIP-110 lacked any contingency for this – no fallback, no revert mechanism. Once activated, the only way to roll back would be another soft fork, requiring 95% consensus. The irony is inescapable: a proposal that sought to lower the bar for change would create conditions where change becomes irreversible.
The Ordinals Paradox
“Hype builds the floor; logic clears the debris.” The ordinals ecosystem generated billions in market capitalization, created new users, and increased transaction fee revenue for miners. By any metric, ordinals are a positive sum game for Bitcoin’s economy – except for the ideological purists who view Bitcoin solely as peer-to-peer cash. BIP-110 attempted to legislate usage norms through protocol constraints, which is antithetical to Bitcoin’s permissionless nature. The community’s rejection was a reaffirmation of the principle: if you don’t like ordinals, don’t use them. But do not prevent others from using the network as they see fit.
Miner Dilemma: Short-Term Pain vs. Long-Term Value
During my audit of the TerraUSD collapse, I learned that circular dependency is the most dangerous design pattern. BIP-110 presented a circular dilemma for miners: reject the fork and lose revenue from ordinals; accept the fork and risk a chain split that would devalue all their BTC holdings. Rational miners chose the latter – by doing nothing, they avoided both risks. The proposal died by inertia, not by active rejection. This is a key insight: Bitcoin’s governance is not democratic; it is inertial. The default state is no change.
In 2020, I modeled the Impermax liquidity trap using discrete event simulations. The lesson: when incentives are misaligned, the system collapses under its own weight. BIP-110’s incentives were misaligned – it asked miners to accept a revenue cut today for an abstract benefit (cleaner blocks) tomorrow. That’s not a trade-off; it’s a subsidy from miners to ideologues.
Contrarian: What the Bulls Got Right
The narrative that BIP-110’s failure proves Bitcoin’s governance is strong is correct – for now. But the contrarian angle is that this failure actually strengths Bitcoin’s long-term investment thesis. Here’s why:
First, the community’s unwavering defense of permissionlessness removes a major regulatory risk. If Bitcoin had adopted even a mild form of transaction discrimination, regulators could pressure future upgrades to censor specific addresses (e.g., sanctioned wallets). By rejecting BIP-110, Bitcoin said: we will not build censorship into the base layer. This positions Bitcoin as the hardest money – immutable in both supply and rules.
Second, the ordinals controversy has had a positive side effect: it has accelerated investment in Bitcoin Layer 2 solutions. Lightning Network capacity hit record highs in Q3 2024. New protocols like RGB and Rootstock are gaining traction. BIP-110’s failure sends a strong signal: do not try to change the main chain; build on top instead. This is creating a vibrant ecosystem of L2s that can handle ordinals, DeFi, and beyond without congesting the base layer. For investors, the real opportunity is not in L1 governance battles but in the L2 infrastructure that will emerge to solve the very problem BIP-110 tried to tackle.
Third, the 1% miner support figure is misleading. It suggests the proposal had no chance, but what if it had been reframed? A better-designed BIP could have offered miners a fee incentive or a temporary subsidy to offset revenue loss. That version might have garnered 30–40% support. The fact that no such proposal emerged indicates a lack of sophistication in the pro-censorship camp. Future attempts may be more nuanced. The bulls are complacent if they think this issue is settled forever.
Takeaway
BIP-110 is dead. The funeral was held in the public square of social consensus, and the epitaph reads: “Thou shalt not reduce the threshold for change.” The question it posed, however, remains unanswered: how does Bitcoin scale without compromising its principles? The answer will not come from the main chain. It will come from the layers above. The question for investors is whether they are positioned for that shift – or still staring at the corpse of a proposal that never had a pulse.
“Hype builds the floor; logic clears the debris.” The debris here is the illusion that protocol changes can solve social disputes. Bitcoin’s governance is its ultimate immune system. It rejected BIP-110 not because the proposal was technically flawed, but because it violated the unwritten constitution: do not touch the consensus rules unless the network is on fire. And ordinals, no matter how annoying to purists, do not constitute a fire.
The next proposal will be smarter. It will offer miners a bribe, buy off exchanges, and manipulate the signaling timeline. When it comes, the community’s immune system must be even stronger. For now, Bitcoin breathes – unchanged, unperturbed, and still the most robust asset on the planet.
