بابلون بروتوكول إيداع البيتكوين يكشف عن ثغرة رئيسية: قد يقلل المُحققون الخبيثون من سرعة توليد الكتل

【BitTui】Bitcoin Staking Ecosystem Faces Technical Risk Again. The development team recently disclosed a critical software vulnerability in the Babylon protocol on GitHub—this flaw is hidden in the BLS voting extension scheme, which was originally designed to ensure validators reach consensus on blocks.

The crux of the issue lies in the block signature mechanism. When validators vote, they need to attach a block hash field to indicate which blocks they support. However, this vulnerability allows malicious nodes to directly skip this field when sending voting extensions. It might sound trivial, but the consequences are problematic—when this occurs during critical consensus checks at epoch boundaries, other validators might crash due to incomplete information.

Imagine if multiple validators are triggered by this issue simultaneously, the block generation speed of the entire network would noticeably slow down. This is not a hypothetical threat—developers explicitly point out that while no active exploitation of this vulnerability has been observed yet, it’s only a matter of time before malicious exploitation occurs if not patched promptly.

For Babylon and the Bitcoin staking ecosystem, this is a timely wake-up call. The security of staking protocols directly affects validator returns and overall network stability, and any consensus-layer vulnerability could potentially evolve into systemic risk.
