Bitcoin BIP-110 Fork Crosses 400 Blocks With Zero Signals

Bitcoin BIP-110 Fork Passes 400 Blocks

The 421-block reading makes the gap more than a brief timing mismatch. The monitor’s BIP-110 node was 419 heights behind the standard node, while its branch measure was two blocks higher because it counts from the mandatory-signaling height at 961,632.

That distinction is important. The data show one BIP-110-enforcing node declining the standard path under its rules and a standard node continuing to accept it. They do not show two histories with comparable hash power, exchange support or economic use.

No public evidence reviewed for this report showed a general Bitcoin payment outage, failed ordinary transactions on the standard chain or broad guidance from major custodians to move BTC. Claims that BIP-110 has already become a Bitcoin-wide consensus rule would exceed what the live node and header data establish.

The fork’s widening is nevertheless a notable operational marker. The proposal’s initial mandatory-signaling start was only a schedule milestone. The subsequent 421 non-signaling blocks show that the standard history has continued well beyond that window’s opening without the signal BIP-110 specifies.

Zero Signals Extend the BIP-110 Deadlock

The monitor marked all 421 scanned standard-branch blocks as non-signaling. It attributed the period’s block production to pools including Foundry USA, AntPool, F2Pool, SpiderPool and ViaBTC, but a block header is not a complete statement of every pool’s policy or every node operator’s preference.

BIP-110 uses a modified BIP9-style deployment. It says its bit 4 is required in the proposed mandatory-signaling range and gives 963,648 as a no-later-than lock-in height, followed by a proposed ACTIVE state at 965,664. Those terms are conditions in a proposal, not a result the current standard chain has met.

The sequence also underscores the gap between software policy and mining power. A small minority chain can remain observable while taking much longer to produce a block, while a higher-work standard history extends. The monitor’s stalled BIP-110 node and advancing standard node are consistent with that dynamic, but do not quantify the hashrate on either path.

The 421-block result is distinct from an earlier 100-block non-signaling update. It passes a fresh 400-block threshold and adds 147 blocks since the most recent 274-block report, while leaving the key fact unchanged: zero observed bit-4 signals in the monitor’s standard-branch tally.

What the 421-Block BIP-110 Split Means for Bitcoin Users

For normal users, the evidence remains narrower than a network emergency. The standard history is the one tracked by the monitor’s standard node and the cited block explorer. No examined source reported an ordinary-wallet migration requirement, a broad service suspension or a general loss of Bitcoin transaction finality.

The more specific risk is for parties that attempt to market or transact an unsupported minority history as though it has broad infrastructure backing. Histories sharing earlier transactions can create operational complexity where replay protections, custody policies and chain selection are unclear. The monitor does not disclose exchange policy, wallet support or a comprehensive economic-activity measure for the short path.

Bitcoin’s quantum-readiness debate is a separate question. BIP-110 concerns proposed limits for certain new data-carrying output constructions, not a confirmed emergency migration for existing Bitcoin holders. The specification says previously created UTXOs would be grandfathered if its temporary rules ever activated.

The Crypto Fear and Greed Index read 29, categorized as Fear, on Aug. 11. The sentiment gauge does not assess which chain is valid or predict the proposal’s outcome, but it provides a cautious market backdrop for an unusually visible governance disagreement.

The next verified checkpoints are whether the BIP-110-enforcing path finds another block, whether any standard-chain header begins carrying bit 4, and whether major mining pools, wallets or exchanges publish operating guidance. Until then, the clearest update is the 421-block, zero-signal standard history, not a completed BIP-110 activation or a Bitcoin-wide disruption.
