Babylon質押代碼漏洞或拖慢區塊產出速度

開發者近日發現,Bitcoin質押協議Babylon存在一個軟件漏洞,可能令惡意驗證者(validator)在提交區塊時故意省略區塊哈希(block hash)欄位,導致驗證者系統崩潰,進而在網絡共識過程中造成阻滯,拖慢區塊產出速度。

這個漏洞影響Babylon的區塊簽名機制——BLS投票擴展(BLS vote extension),該機制用以證明驗證者對某個區塊達成共識。根據周四在GitHub發佈的安全公告,惡意驗證者可利用漏洞在發送投票擴展時故意忽略區塊哈希欄位。區塊哈希告訴驗證者他們實際上是在投票支持哪個區塊,缺失此欄位會造成共識問題,特別是在網絡的epoch邊界時期。

理論上,這種漏洞可令惡意驗證者在epoch邊界進行關鍵共識檢查時觸發其他驗證者崩潰,若多個驗證者受影響,將導致區塊產出速度明顯放慢。

發現漏洞的匿名貢獻者GrumpyLaurie55348指出:「在epoch邊界時,驗證者會間歇性崩潰,拖慢該區塊的產生。Babylon在共識關鍵代碼路徑(尤其是VerifyVoteExtension和提案時的投票驗證)中,會對這個空指標進行解引用,導致運行時恐慌(runtime panic)。」

截至發稿,Cointelegraph已聯絡Babylon團隊了解漏洞影響及修復方案,但尚未收到回覆。開發者強調漏洞尚未被主動利用,但若不及時修補,仍有被濫用風險。

Babylon持續擴展Bitcoin收益生態

Babylon被視為Bitcoin去中心化金融(DeFi)領域的重要創新,首次在加密貨幣歷史中推出了Bitcoin原生的質押功能。Bitcoin DeFi(簡稱BTCFi)是新興技術範式,旨在將DeFi能力引入世界首個區塊鏈網絡,這得益於2024年Bitcoin減半期間推出的Runes協議。

本周三,Babylon從著名風險投資機構a16z Crypto獲得1500萬美元融資,資金來自Andreessen Horowitz數字資產部門透過出售Babylon原生代幣BABY所得。a16z Crypto表示,這筆資金將用於推動Bitcoin原生DeFi基礎設施的持續發展。

今年12月,Babylon與Aave Labs合作,將Bitcoin抵押貸款功能引入Aave v4,允許BTC作為抵押品使用,無需包裝代幣或托管機構。該產品預計於2026年第一季度進入測試階段,並計劃於2026年4月聯合正式推出。

評論與分析

Babylon此次發現的漏洞凸顯了Bitcoin生態系統中DeFi基礎設施發展的風險與挑戰。Bitcoin作為最早且最廣泛使用的區塊鏈,其安全性向來被視為業界標杆,但隨著複雜功能如質押和DeFi應用的引入,系統的複雜度和潛在攻擊面也同步增加。這次BLS投票擴展的漏洞雖未被證實遭到利用,但其可能引發的共識崩潰和區塊產出延遲,提醒我們在追求創新同時,必須嚴格把控安全風險。

另一方面,Babylon獲得a16z Crypto的巨額投資,顯示市場對Bitcoin DeFi的未來充滿期待。Bitcoin原生的質押和貸款功能若能成功推廣,將為Bitcoin生態注入新的活力,吸引更多資金和用戶參與。但這也意味著,Babylon及類似項目必須加強代碼審計和安全測試,避免因漏洞導致用戶信心受損,甚至造成資產損失。

總體而言,Babylon的案例是Bitcoin DeFi發展過程中的一個縮影,展現了技術創新與安全保障的雙重考驗。未來,如何在保持去中心化和安全性的前提下,推動Bitcoin功能多元化,將是整個行業需要深思的課題。

A cinematic high-angle portrait of a young woman looking up at the camera, intense expressive eyes with sharp focus, natural freckles and soft skin texture, slightly messy brown hair adding realism and motion, wearing a simple white sleeveless top and casual denim shorts, minimal accessories, urban lifestyle vibe. Shot from an overhead perspective creating depth and vulnerability, shallow depth of field with softly blurred concrete background, dramatic soft lighting with subtle shadows, moody color grading, high contrast, ultra-realistic skin tones, professional fashion photography style, 85mm lens look, f/1.8, cinematic realism, editorial portrait, 8K detail, film grain, modern aesthetic, photorealistic. Prompt:
Use my image in Ultra-realistic, hyper-detailed, 8K cinematic portrait of a young stylish man, using the uploaded image for exact face and hairstyle.
Outfit: An oversized red knit sweater with white hearts, exactly as described in the prompt.
Pose: A hyper-realistic close-up portrait with a messy, cropped framing showing only the boy holding the book. His left hand rests on the wooden table and covers part of his cheek, with a subtle smile on his lips. His other hand holds the book titled "Something I Never Told You" with the word "YOU" written in pink, exactly as
described in the prompt. Background: Not specified. Base Setup

keep 100 percent facial information adherence of the attached image and turn her into a fashion model walking through a dim stone tunnel toward a bright exit, captured as a live action photograph or movie still, not an illustration or CGI render. Her styling leans seductive and attractive through fashion, attitude, and mood rather than explicit content.

Shot and Camera

Full body silhouette shot from behind at slightly low camera height, matching the original perspective and narrow tunnel framing. Keep her stride, tunnel curvature, and vanishing light exactly as seen.

Identity and Pose

Preserve her height impression, slim silhouette, hair length, and body proportions. She walks forward with one hip subtly angled, natural arm swing, confident stride, and a slow, sensual rhythm. Her head tilts slightly as if aware of being watched. Include 8k Photorealistic and hyper realistic.

Lighting and Environment

Strong backlight from the tunnel exit creates a glowing rim around her body, with soft, scattered reflections on the wet stone floor. The tunnel remains dark with textured stone irregularities and real moisture streaks. Add subtle haze for realism and keep the environment grounded with accurate shadows and surface wear.

Masking and Constraints

Change only the outfit and styling, keep lighting, perspective, white balance, pose, face geometry, body proportions, and silhouette the same. Absolutely no added text, no cartoon look, no CGI sheen, no plastic skin, no floating feet, and no overly clean backgrounds. Maintain consistent perspective, grounded contact shadows, film like grain, and full live action realism.
