The BIP-110 Autopsy: How a Two-Block Fork Proved Miner Veto Is Bitcoin's Only Constitution

Hook At block height 961,632, a small group of Bitcoin node operators decided they owned the protocol. Their client began rejecting every block that did not carry a BIP-110 support signal. Eight hours later, the rebellion had produced exactly two blocks. The main chain did not blink. Everyone is watching the price; no one is watching the plumbing. But this time the plumbing failed so loudly that even order books should have heard it. Context BIP-110 is not a scaling proposal. It is a weaponized rule change designed to purge non-financial data from Bitcoin's block space—a direct attack on Ordinals, BRC-20 tokens, and every data-heavy experiment living on L1. The activation path was even more telling. Instead of gathering miner support through the standard BIP-9 signaling mechanism, BIP-110 nodes forced the issue at a specific height, a UASF-style ultimatum: run our rules, or your blocks do not exist. The previous difficulty period had recorded only 51 out of 2,016 blocks carrying the signal—2.53%. The proposal demanded 55%. That is not a negotiation. That is a declaration against arithmetic. To understand why this failed, look at the mechanism, not the drama. A UASF is a political bomb: a client sets a flag date, and after that date, nodes with the new rules treat every old block as invalid. If enough economic nodes run it, miners are forced to follow or lose their revenue. If not, the bomb explodes only in the faces of the people holding it. BIP-110 was a bomb with a fuse made of wet cardboard. Core Analysis Hashrate is the only constitution. Let's do simple arithmetic. Bitcoin targets one block every ten minutes. Eight hours of expected production means forty-eight blocks. The BIP-110 chain produced two. That puts its active hashrate at roughly four percent of the network—and probably much closer to a single miner testing a theory than a movement testing a mandate. This is not a fork. This is a pothole on a highway. The proposal's target list is important. It wanted to restrict OP_RETURN-like data, inscription metadata, and any non-financial payloads. That is not a neutral efficiency upgrade. It is a land-use law for block space. Land-use restrictions are always political choices. In traditional finance, we call this zoning. BIP-110 was zoning without a vote, and the miners responded the way property owners always respond to unapproved zoning: they ignored it. The real failure is not cryptographic; it is economic and political. BIP-110 would have redefined block space from an auction open to all bidders into a restricted lane for financial transactions only. That means miners would lose a meaningful stream of fee revenue generated by Ordinals-related transactions. I spent 2020 dissecting Uniswap v2 and cross-border settlement; I spent 2021 modeling NFT volumes against the dollar index. The lesson recurred constantly: when a protocol asks its security apparatus to cut its own revenue for ideological purity, the protocol loses. Miners did not reject BIP-110 because they love inscriptions. They rejected it because they have electricity bills. Tracing the liquidity ghosts through the ICO fog taught me that participants follow incentives, not ideology. The 2.53% signal rate is the part every analyst should frame. Fifty-one blocks out of 2,016 signaled support. Under BIP-9, a soft fork would need 95% in a difficulty period; BIP-110 lowered the bar to 55% and still couldn't get close. But the support-failure analysis misses a deeper point: this was never a coordination problem. The proposal's supporters tried to weaponize UASF because they knew they had no miner alignment. They wanted node operators to act as a judiciary, overriding the miners' economic vote. In Bitcoin's governance, that is like holding a vote in one country to change the laws of another. It produces noise, not law. The deeper macro lesson is that liquidity hides governance debt. In a bull market, money flows into narratives long before the technical infrastructure is tested. BIP-110 failed eight hours after launch because the infrastructure did not exist. But the same pattern appears across the crypto ecosystem: products launch with tiny real usage and hope that liquidity will paper over structural gaps. I saw it in the ICO boom, in the yield-farming summer, and in the NFT land grab. The block height was different. The physics were identical. Bear case: BIP-110's failure is not a victory for open block space. It is a demonstration that miners have a veto they are willing to use to protect revenue. That veto cuts both ways. Today it protects Ordinals. Tomorrow it could protect a cartel-friendly fee schedule, or a mining pool that decides to filter high-value inscriptions off-chain while keeping the base layer clean. The same economic rationality that killed BIP-110 can be used to reintroduce its policy in a subtler form: not by changing consensus rules, but by changing who gets to bid. I keep tracing the liquidity ghosts through the ICO fog, and I see the same sequence: a failed ideological attack is followed by a successful financial capture. What did the fork actually accomplish? A two-block chain is not a chain; it is a tombstone. It cannot safely custody value, it cannot support payment channels, and any exchange that lists its token is listing a promise backed by a rounding error. Based on my audit experience with low-hashrate forks, I would advise anyone holding "BIP-110 Bitcoin" to treat it as a collectible, not an asset. The main chain at 961,681 kept moving while the fork froze at 961,633. That forty-eight-block gap is the message: the network can absorb dissent without restructuring. Compare BIP-110 with the successful BCH fork of 2017. BCH had key mining pools, exchanges, and a loud community behind it before the split. BIP-110 had none of that. It tried to trigger a split with less than three percent miner support. The only comparable scenario in modern monetary history is a central bank announcing a currency redesign with no one printing the new notes. The two blocks it produced are not a mark of resilience; they are a mark of how little support a faction can have and still create a timestamp. What about the Ordinals holders? The immediate reading is relief. But I would urge caution. The same miners who ignored BIP-110 are the ones who profit from inscription traffic. If a future fee market reform reduces that profit, these same miners may support a more effective mechanism. The longevity of Ordinals is not guaranteed by consensus rule; it is guaranteed by the revenue line on a mining pool's balance sheet. Revenue lines can be re-engineered. That is the real fragility hiding behind the celebration. The Contrarian Read The market will likely frame this as "Ordinals survives, Bitcoin unchanged." I think the opposite is true. Bitcoin has not resisted change; it has surrendered to miner capitalism. The UASF attempt failed, but it exposed a governance truth that should disturb purists: the miners are the ultimate arbiter of what Bitcoin is. That is not decentralization. It is industrial democracy with a specific constituency. The BIP-110 collapse also means the "data purge" crowd will adapt. They will stop trying to change consensus and start trying to change incentives. They might propose a fee reform that makes inscription-heavy transactions wildly expensive, or a mempool policy that labels Ordinals as "spam" and refuses to relay it. The next attack on Ordinals will not be a flag day at a block height. It will be a quiet policy in a mining pool's documentation. The BIP-110 story is not about two blocks. It is about the slow migration of power from consensus rules to mempool policies. Takeaway Watch the next twelve months for two things: script-level proposals such as OP_CAT and BIP-119, and the fee behavior of the largest mining pools. If a major pool begins silently dropping high-data transactions, you will know that BIP-110's agenda has merely changed its uniform. The fork was a two-block footnote, but the economics that killed it are the same economics that will shape the next battle. Tracing the liquidity ghosts through the ICO fog is not a hobby. It is a survival skill. The next rebellion won't announce itself at a block height. It will appear as a fee schedule, not a manifesto, yet.
