There are about 1790 blocks and over ten days until the Bitcoin network starts the mandatory signaling window for BIP-110 at block height 961632; based on the current block generation rate, this window is expected to open around August 9, 2026. As of July 27, 2026, 8:40 (EDT), the total network block height is only around 959842, and BIP-110 remains in the "pre-statement night." This should be a technical vote on the protocol upgrade: miners write "support" or "silence" in the block header signaling field to vote on the proposal's fate with on-chain data. However, according to a single public data source, so far, only about 2.64% of the mined blocks carry BIP-110 support signals, meaning that the vast majority of miners have either not yet made a decision or choose to remain silent. During the mandatory signaling window, if the support rate does not reach the undisclosed threshold, the proposal may be postponed or even become void, putting the Bitcoin community, which has long had disagreements over scalability and transaction processing methods, into a tense and unclear state once again: miners, developers, and a broader base of holders all understand the countdown has begun, but no one can predict where this on-chain vote will ultimately land.
Countdown to the Mandatory Signaling Window: Only 1790 Blocks
The so-called "mandatory signaling window" is a limited interval in the Bitcoin soft fork process: within a pre-agreed height range, the network assesses miners' votes for a proposal by counting specific signals in the block headers. For BIP-110, this key interval is anchored at block height 961632, and starting from this height, whether each new block carries the BIP-110 signal will be counted toward the total support rate, determining whether this proposal, aimed at adjusting block size or transaction processing mechanisms, can continue to be advanced.
As of July 27, 2026, 8:40 (EDT), the Bitcoin block height is approximately 959842, which is about 1790 blocks away from 961632. Roughly estimating an average of one block every 10 minutes, this means that miners have only a little over ten days remaining; the mandatory signaling window is expected to open around August 9, 2026. For power participants spread across different time zones, each with varying operating costs and risk preferences, this is not a long transition period where they can continue to observe from the sidelines, but rather a countdown process in which they must complete internal assessments, deploy or upgrade nodes, and clearly express their positions via block header signal within a short timeframe.
2.64% Support Rate: Why Miners Remain Silent Collectively
The countdown has begun, but the on-chain attitudes are still nearly blank. According to a single public data source, currently, blocks carrying the BIP-110 signal account for only about 2.64% of all blocks; under the mechanism where soft fork upgrades rely on block header signaling to gauge support, this indicates that the vast majority of recent blocks have not written in a support position. In other words, during this critical preparatory period before the mandatory signaling window opens, the main computing power of the Bitcoin network has chosen to "not express a position," making it challenging for anyone to determine which step this upgrade is at on the miners' side.
This silence should not be hastily interpreted as opposition; it resembles a complex state layered with asymmetric information, watchful sentiment, and divergent opinions on the route. On one hand, the specific technical parameters of BIP-110 have not been fully laid out in public materials, and some miners may still be internally assessing the upgrade's impact on their cost structures and risk management processes; on the other hand, the Bitcoin community's long-standing arguments over scalability routes and transaction processing methods have made it more cautious for power participants when it comes to taking a stance. Current public materials do not provide detailed statements from major mining pools or mining organizations on BIP-110; the only number visible from external observations is this 2.64%, which comes from a single statistical source. Before the mandatory signaling window truly opens, the support rate has evident potential for increase or fluctuation. Therefore, any judgment of "miners collectively rejecting the upgrade" is premature; a more reasonable attitude is to see this silence as a mid-game phase of an unfinished contest.
BIP-110's Position Amidst the Aftershocks of Scalability Disputes
In the aftermath of the long-standing disputes over scalability routes, BIP-110 has been placed in a sensitive position. Current public materials only describe it as a proposal "aimed at adjusting the Bitcoin block size or transaction processing mechanism," without disclosing specific parameters or implementation paths. However, just touching on block capacity and throughput structure is enough to place it within that familiar line of argument: whether to let each block hold more transactions or stick to allowing as many people as possible to run full nodes and fully validate. These two objectives are destined to be difficult to maximize simultaneously. Throughput, fee levels, and node running costs are interdependent; any slight shift on one side will be amplified by participants on the other side.
Bitcoin protocol upgrades typically adopt a soft fork path, where miners express their attitude through block header signals, and BIP-110 is no exception. As the mandatory signaling window approaches, this proposal essentially brings the old question of "how to improve performance without sacrificing decentralization" back to the forefront. However, this time, the public information available for community discussion is considerably less, with only the upcoming signaling mechanism and the current 2.64% support signal seen while lacking sufficient technical details to determine what it will change on-chain. This asymmetry of information and responsibility itself is becoming a core variable on the path to advancing BIP-110.
The Network Risks That Mandatory Signaling May Ignite
Entering the mandatory signaling window with approximately 2.64% of the on-chain blocks clearly expressing support signals means that a state of not forming a clear majority will be "locked into" a time-limited signaling period. For some developers and supporters, this is seen as a necessary procedure to advance the upgrade and compel miners to express their position. However, for observers and opponents, it seems more like prematurely starting the countdown before consensus has taken shape, thus amplifying the division over "should we continue to push BIP-110 at this time?".
According to the existing public materials, if the support rate does not reach the pre-set but undisclosed threshold during the mandatory signaling window, BIP-110 may be postponed or even become void. This uncertainty directly impacts governance expectations: a path originally described as "gradual" could turn into a shelved proposal at any time when the window closes. From a technical perspective, mandatory signaling provides a clear on-chain path for the upgrade—concentrating on the fixed block height to tally miners' attitudes, determining whether to enter the subsequent activation process. However, at the governance level, this mechanism also raises the pressure on network stability and trust during periods of insufficient consensus, as each party must stake their position within a limited time. Once the result falls into the "below threshold" range, what remains is not just an unfinished upgrade, but collective questions on how Bitcoin will handle similar proposals in the future.
Three Things to Watch in the Next Two Weeks
From now until the expected opening of the mandatory signaling window around August 9, 2026, there are only three key things to watch: first, will the on-chain support rate visibly rise from the current approximately 2.64% level, even if it's just transitioning from "almost no statement" to "a few miners testing"? Second, will major mining pools, core developers, and leading service providers break their silence to provide clear support or reservations, offering interpretable references for future block signaling? Third, will internal discussions within the Bitcoin community converge on a new consensus direction amid the tug-of-war between scalability and security—even if the conclusion is to postpone BIP-110, it is still a form of consensus. It should be emphasized that all current judgments are based on a single source of on-chain signal data, and once multiple sources cross-verify or new public statements emerge, any assessments of BIP-110's prospects today could be significantly revised. What truly needs observation is how Bitcoin recalibrates the balance between "programmatic upgrades" and "genuine consensus" in this event and provides a governance answer that can be trusted in future similar proposals.
