Bitcoin | BIP-110 Failed to Gain Miner Support, BIP-54 Takes Center Stage

Bitcoin has not seen a consensus rule change since the activation of Taproot in November 2021, marking the longest stretch of inaction in its history. BIP-110's signaling window opened around block 961,632 in early August, but miners barely supported it, with support lingering below 1% until the end of July.

The Fallout from BIP-110

The lack of major mining pools committing to BIP-110 brings serious questions about the signaling process. F2Pool rejected the proposal outright, while AntPool stayed silent on the matter. Foundry USA opted for a hashrate weighted vote instead, further complicating the scenario.

"If pools can't even coordinate on that, what happens when something really urgent comes up?" said one concerned participant. It looks like miners are hesitant to adopt proposals, even those aimed at fixing security vulnerabilities.

What's Next: BIP-54

With BIP-110 now sidelined, the focus shifts to BIP-54, which aims to patch a vulnerability known as a "timewarp attack". This exploit could allow attackers with majority hashrate to manipulate timestamps and drive mining difficulty down significantly, disrupting contract payments on the Lightning Network. The proposed solution would implement timestamp limits at both the start and end of each 2016 block difficulty period.

Interestingly, discussions surrounding BIP-54 are not new—it dates back to 2023-2024. It received its BIP designation in April 2025, and the spec was finalized this past May after successful testing.

Miner Coordination Issues

Participants are puzzled about the miner coordination problem this situation reveals. Many believe that crucial fixes should not face the same signaling bar as feature enhancements. One pointed out, "Making miners 'want' a timewarp fix is a weird dynamic — they gain nothing by leaving a vulnerability open, unless they’re exploiting it themselves."

"The high bar argument makes sense in theory, but BIP-54 addresses a known attack vector," another commenter agreed.

Takeaways from BIP Discussions

• 🔒 Security concerns dominate discussions about BIP-54, contrasting with earlier feature proposals.

• ⚠️ An alarming absence of support for BIP-110 could signal ongoing challenges for future proposals.

• 📉 "Miners dragging their feet on a real security fix feels like watching someone refuse to lock their door."

As discussions continue, many hope that the challenges faced by BIP-110 don't hinder the implementation of essential fixes like BIP-54. With the stakes so high, the crypto community remains on edge, questioning how future changes will be navigated.

The Way Forward for Bitcoin Proposals

The current climate suggests that BIP-54 may see more favorable reception among miners compared to its predecessor BIP-110. Given the urgent nature of the timewarp vulnerability, there’s a strong chance that miners will prioritize security in the coming months, potentially leading to increased support for BIP-54. Experts estimate around 70% approval from major mining pools as discussions heat up, driven by the need to protect the integrity of the Lightning Network. If there are no major pushbacks, the implementation could happen as early as mid-2026, allowing Bitcoin to regain traction in its development process.

A Lesson from the Past: Software Security and Urgency

This situation recalls the early days of software development when critical patches often faced scrutiny but ultimately prevailed due to pressing security needs. Many businesses once hesitated to adopt critical updates until a major security breach forced their hand, echoing the current sentiment in the Bitcoin miner community. Just as companies learned to adapt and prioritize security over features, the Bitcoin ecosystem might have to confront its vulnerabilities directly. It's a vivid reminder that delay in addressing security flaws can have long-term ramifications—an invaluable lesson as the crypto landscape evolves.
