The BIP-110 Fork: A Failed UASF and the Economic Reality of Bitcoin Governance

The chart whispers; the ledger screams the truth. On block height 961,681, Bitcoin’s main chain quietly continued its 10-minute cadence. Eight hours earlier, at height 961,632, a minority of node operators had triggered a unilateral fork based on BIP-110—a proposal to restrict non-financial data in Bitcoin transactions. The result? A ghost chain: two blocks in eight hours, a 48-block deficit against the main chain, and zero miner support. This was not a fork. It was a protest. I’ve watched this pattern before. In DeFi Summer 2020, I saw liquidity protocols try to enforce rules that ignored miner incentives. The market always wins. The BIP-110 fork is a textbook case of what happens when idealism meets economic gravity. As a macro watcher, I see this as a liquidity event—not of capital, but of hash power. The miners voted with their ASICs, and the result was clear: 2.53% signal support in the previous epoch, 55% threshold unmet, and a chain that couldn’t sustain a single meaningful transaction. Context: The Battle for Bitcoin’s Block Space BIP-110 aimed to limit the amount of non-financial data that can be embedded in Bitcoin transactions. The primary target: Ordinals inscriptions, which have turned Bitcoin into a settlement layer for digital artifacts. The proposal was a ‘subtraction’—it didn’t add functionality; it removed the permission to use block space for data-heavy applications. To activate, it required 55% of blocks in a 2,016-block window to signal support. That’s a mid-range threshold, lower than the 80% used in BIP 91, but higher than the simple majority of BIP 148. The designers hoped to create a gamified pressure: miners would eventually comply to avoid chain split. They miscalculated. Why? Because miners are not idealists. They are profit-maximizers. Ordinals transactions have become a significant source of fee revenue. In 2025, inscription-related fees accounted for nearly 15% of total Bitcoin transaction fees during peak periods. Any proposal that cuts off that revenue stream would face resistance. The 2.53% support rate was not a signal of apathy; it was a silent veto. The follow-through fork—initiated by node operators who refused to accept non-signaling blocks—was a UASF in spirit, but without hash power, it was dead on arrival. Core: The Failure Mechanism and Its Implications Let’s dissect the mechanics. The fork was triggered by nodes rejecting blocks that didn’t include a BIP-110 signal. This is a classic UASF move, similar to the BIP 148 activation of SegWit in 2017. But there is a critical difference: SegWit had overwhelming miner support once the signal threshold was reached. BIP-110 had almost none. The result was a chain with such low hash rate that it could only produce two blocks in eight hours. For context, the main chain produced 49 blocks in the same period. The fork chain’s security was effectively zero—a 51% attack would require a single laptop. From a technical standpoint, this demonstrates the flaw in assuming that node-enforced rules can override economic incentives. In Bitcoin’s Proof-of-Work consensus, the chain with the most accumulated work is the canonical chain. A fork without work is a fork without legitimacy. The BIP-110 fork is a perfect example of the ‘UASF dilemma’: you can enforce a rule, but you cannot force miners to mine. The network’s resilience lies in its economic alignment, not its code. I’ve seen this play out in traditional finance too. In 2022, during the LUNA collapse, I shorted overleveraged DeFi positions because I knew the economic incentives would force a deleveraging. The same logic applies here: miners will not support a rule that cuts their fees. The BIP-110 proponents failed to provide any compensating mechanism—no fee redistribution, no subsidy, nothing. The proposal was a pure cost imposition on miners, and they rejected it. Now, what does this mean for Ordinals? In the short term, it’s a reprieve. The ‘risk of regulation via protocol change’ is off the table for now. But this is not a permanent victory. The conflict between Bitcoin’s original vision as a ‘purely monetary network’ and its current role as a ‘permissionless data ledger’ is far from resolved. The 2.53% support rate may seem small, but it represents a committed minority—node operators who are willing to incur costs to express their displeasure. They will try again, possibly with a more sophisticated approach. Contrarian: The Decoupling Thesis and the Real Fragility The conventional narrative is that the BIP-110 fork failure is a win for decentralization and user choice. I disagree. This event reveals a structural fragility: Bitcoin’s governance is not as decentralized as its proponents claim. The power to veto protocol changes lies with a small number of large mining pools. In 2025, the top five pools control over 60% of the hash rate. Their economic interests are not aligned with the broader user base. They are not elected; they are market participants. And they will act to protect their revenue streams. The decoupling thesis that Bitcoin can be both a store of value and a settlement layer for data is under strain. If Ordinals fees continue to grow, they will eventually crowd out lower-value transactions, increasing transaction costs for ordinary users. At that point, the community may face a choice: accept high fees or restrict non-financial data. The BIP-110 failure does not solve this; it postpones it. The structural fragility is that the miners’ economic incentives are short-term (fee revenue) while the network’s long-term health requires predictable, low-cost transactions. This is a classic time-inconsistency problem. Capital flows where intelligence meets speed. The intelligence here is to recognize that the battle for block space is not a technical debate; it’s a liquidity allocation problem. Hash rate is liquidity. It flows to where the returns are. If Ordinals provide higher returns, miners will support them. If the returns decline, they will switch. The BIP-110 proponents failed to understand that they were asking miners to accept lower returns for no compensation. That is a losing proposition in any market. Takeaway: The Next Cycle and Positioning History does not repeat, but it rhymes in code. The BIP-110 fork is a minor event with major implications. It shows that Bitcoin’s governance is not a democracy; it’s a plutocracy of hash power. For investors, the immediate takeaway is that Ordinals have a policy tailwind—the risk of a protocol-level ban has been temporarily removed. But the long-term risk remains: if Ordinals fees become too large, they will attract regulatory scrutiny and internal pressure for change. My positioning: I am neutral on Bitcoin’s price in the short term, but I am watching the fee market closely. If Ordinals transactions rise above 20% of total fees, I expect a new wave of proposals—possibly more moderate ones, like limiting inscription size rather than banning them outright. The next attempt will be smarter, with better economic incentives. The BIP-110 failure is not the end; it’s the beginning of a longer negotiation. The chart whispers: the fork failed. The ledger screams: the miners won. But the game is not over. The next cycle will test whether Bitcoin can remain a neutral settlement layer or whether it will be forced to choose between monetary purity and data utility. I’m betting on the latter, but I’m hedging my position with exposure to layer-2 solutions that can offload data traffic. In the end, capital flows where intelligence meets speed—and the intelligence of the market is that block space is too valuable to be constrained by ideology.
