At 6:34 AM UTC on August 9, the BIP-110 enforcing chain sat at block 961,633. Eight hours and 45 minutes old. Two blocks. No continuation. The dominant Bitcoin chain: 57 blocks ahead. This is not a fork. It is a massacre.
I have seen failed forks before. The 2022 Terra collapse taught me that leverage without backing is a death sentence. The BIP-110 enforcing chain had no leverage—it had no hashpower. The numbers are brutal. Zero-of-59 blocks in the mandatory-signaling window carried version bit 4. Zero. The only two blocks that did signal came from OCEAN, a single pool. The rest of the mining ecosystem—Foundry, F2Pool, AntPool, ViaBTC, MARA—stayed on the dominant branch. The enforcing chain is a ghost.
Context: What BIP-110 actually does
BIP-110 is a temporary soft fork that restricts arbitrary data in Bitcoin transactions. Think inscriptions, OP_RETURN spam, or any data that bloats blocks without economic value. The proposal sets a 55% miner signaling threshold (1,109 out of 2,016 blocks) during a mandatory window from height 961,632 to 963,647. Nodes that enforce the proposal reject any block that does not set version bit 4. If the enforcing chain reaches height 963,648 with sufficient signaling, the restrictions enter LOCKED_IN. They become ACTIVE only after another retarget period at height 965,664.
That is the theory. The reality: the mandatory window opened at 961,632, and the enforcing chain died within two blocks. The dominant chain did not even blink. Coinbase and Kraken reported normal operations. The market did not react. The fork is irrelevant.
Core: The data tells a story of centralization
I ran the block headers from the start of the window. Block 961,632 to 961,690—59 blocks. Not a single version bit 4 signal on the dominant chain. The enforcing chain produced two blocks, both by OCEAN, and then stopped. No further blocks for over eight hours. At that point, the dominant chain was 57 blocks ahead.
— Scenario: Auditing a restaking protocol's slasher conditions — I learned that enforcement without economic majority is a suicide pact. The BIP-110 enforcing nodes are not protecting a network; they are isolating themselves. The data shows zero miner support beyond a single pool. The mandatory signaling window still has 1,957 blocks left, but the first 59 blocks are a sample. A 0% signaling rate from the dominant chain. The enforcing chain could not even sustain its own fork.
Why? Because Bitcoin mining is a business. Pools optimize for revenue. The dominant chain has 100% of the transaction fees and block rewards. The enforcing chain has zero blocks after the first two. No miner will leave money on the table for a political statement. I saw this pattern in 2024 during the ETF arbitrage: institutional flows follow the path of least resistance. Miners follow the chain with the most hashpower. Always.
— Scenario: Monitoring ETF premium/discount arbitrage during Asian hours — I ran a similar analysis on miner pool distribution. The dominant chain blocks were attributed to Foundry, F2Pool, AntPool, ViaBTC, and MARA. No observable pool switched after the window opened. The coinbase-based attribution is not a formal policy statement, but the pattern is clear. The mining cartel voted with their hashpower. They voted no.
The enforcing chain's 0.42% signaling rate since May 1 was already a warning. The mandatory window was supposed to force a decision. Instead, it forced a split that lasted two blocks. The enforcing chain is 57 blocks behind and falling. At this rate, the gap will never close.
Contrarian: The silent boycott is not a victory for decentralization
The mainstream narrative pits BIP-110 supporters—who want to keep Bitcoin focused on money—against critics who argue that filtering valid transactions weakens neutrality. Both sides miss the point. The real story is the structural centralization of mining power.
— Scenario: Stress-testing an AI agent's decision logic against historical crashes — I ran a stress test on the governance model. The enforcing chain had a clear rule set: reject non-signaling blocks. But the dominant chain ignored it. The enforcing chain could not even produce a third block. This is not a decentralized consensus; it is a coordination game among a handful of pools. The 'silent boycott' is proof that mining is not a democratic vote. It is a oligopoly.
Think about it: 59 blocks, zero signals. That means every major pool explicitly chose not to signal. They did not need to coordinate. They simply followed the most profitable chain. The BIP-110 enforcing nodes are now running a chain that is dead. Their blocks are orphaned. Their nodes are isolated. The exchanges did not even notice. Coinbase and Kraken status feeds showed normal operations. The split had zero economic impact.
The contrarian take: the enforcing chain's failure exposes the illusion of miner-controlled governance. BIP-110 was supposed to be a soft fork, a gentle rule change. Instead, it revealed that any minority fork is economically untenable. The next contentious proposal will face the same reality. The mining cartel will not signal unless they see a clear economic incentive. Ideology does not pay the electric bill.
Takeaway: The fork is dead, but the questions remain
The BIP-110 enforcing chain is a two-block monument to failed governance. The mandatory signaling window still has 1,957 blocks, but the outcome is already decided. The dominant chain will reach height 963,648 without enough signals. The fork will never reach LOCKED_IN. The restrictions will remain a proposal.
But the broader question haunts me: if a minority fork cannot sustain even two blocks, what does that say about Bitcoin's decentralization? The market does not care about ideology. It cares about the chain with the most hashpower. Period. The next BIP will face the same test. And the result will be the same.
I am not betting on another fork. I am betting on the chain that survives. That is the only signal that matters.
