At block 961,632, the mandatory signaling window for BIP-110 opened. The enforcing chain expected miners to set version bit 4. Instead, the next 59 blocks on the dominant chain carried zero signals. Zero. The enforcing nodes found themselves on a two-block branch, 57 blocks behind. Eight hours and 45 minutes without a single new block on that branch. This is not a slow start. This is a coordinated rejection. The BIP-110 chain is effectively dead, and the data is unequivocal.
BIP-110 is a proposed temporary soft fork that restricts certain methods of embedding arbitrary data in Bitcoin transactions. Its supporters argue it keeps the blockchain focused on monetary use. Opponents see it as censorship. The proposal uses a 55% threshold over a 2,016-block window starting at height 961,632. For nodes enforcing the rule, blocks without bit-4 are invalid. The split was inevitable. But the speed of the collapse is telling. The enforcing branch produced only two blocks, both by OCEAN pool, then stalled. The dominant chain, carrying blocks from Foundry, F2Pool, AntPool, ViaBTC, and MARA, continued without interruption. The mandatory signaling window has 1,957 blocks remaining, but the initial signal is zero. Based on my experience auditing consensus mechanisms, this is a fatal sign.
I do not read the whitepaper; I read the bytecode. But here, the bytecode is irrelevant. The consensus is social. The data from block explorers shows that from height 961,632 to 961,691, not a single block on the dominant chain set bit 4. The probability of 59 consecutive non-signaling blocks under a random distribution, assuming even a 10% signaling rate, is less than 0.1%. This is not chance. Major mining pools have coordinated a silent boycott. The ledger remembers what the team forgets. The enforcing chain's two blocks, both from OCEAN, are isolated. They are not building on top of each other; they are orphaned in everything but the enforcing node's view. The snapshot at 06:34 UTC on Aug 9 shows the dominant chain at 961,690, the enforcing branch at 961,633. That's a 57-block gap, growing. The BIP-110 state machine requires reaching height 963,648 for LOCKED_IN, then 965,664 for ACTIVE. The enforcing chain is nowhere near those targets. Even if it started producing blocks now, it would need to catch up and maintain a majority of hashrate. But the miners have spoken. Code is the only witness. The coinbase-based pool attribution shows zero major pool switching. Foundry, F2Pool, AntPool, ViaBTC, MARA all produced blocks on the dominant branch. No observable policy change. The enforced chain is a ghost chain. I have seen this pattern before. In 2020, during the BIP-148 UASF debate, similar signaling failures led to the proposal's abandonment. The difference is that BIP-110 is a soft fork, not a user-activated one. The miners hold the keys. And they are not turning. The exchange status feeds from Coinbase and Kraken show normal operations. That is a diplomatic way of saying "nothing to see here." But the chain split is real. For enforcing nodes, Bitcoin is broken. For the rest, it's business as usual.
The contrarian view: the mandatory signaling window is only 59 blocks in. There are 1,957 blocks left. Miners could change their mind. Perhaps they are waiting to see if the proposal gains more node support. The BIP-110 supporters argue that the low initial signaling is typical for contentious proposals and that the threshold can be met later. Some even claim that the two-block branch is a necessary stress test, proving that the network can handle a split without catastrophic failure. But this is wishful thinking. The pattern of zero signaling from the top five pools is not a random fluctuation. It is a deliberate signal. The probability of such a streak under any reasonable assumption of miner support is negligible. The enforcing chain's hashrate, as measured by the orphaned blocks, is less than 0.1% of the total. To catch up, they would need to attract a massive shift in hashrate. That is not happening. The window is 2,016 blocks, not 59. But the first 59 blocks are the most important. They set the tone. And the tone is rejection. The contrarian argument ignores the social cost of switching. Pools that switch to the enforcing chain risk producing blocks that are not recognized by the majority. That is a losing proposition.
The BIP-110 fork is a textbook case of miner veto. The mandatory signaling window was designed to force a decision. Instead, it forced a split. The enforcing chain is now a historical artifact, two blocks long. The remaining 1,957 blocks are irrelevant. The outcome is clear: Bitcoin's consensus is not just code; it is the collective action of miners. The proposal is dead. The question is not whether BIP-110 will activate. It is whether the Bitcoin community will learn from this failure. The ledger remembers. And so do I.
