Base表示序列器故障導致區塊生產中斷33分鐘
======================================================================

根據Base的說法,故障於8月5日06:07 UTC開始,當時活躍的序列器因鏈上活動造成的擁堵而落後。

由於序列器的故障,Coinbase的Base第二層區塊鏈在週二的活動中停滯了33分鐘。開發人員在一份後期報告中指出,這次故障是因為序列器故障轉移未能如預期恢復。

事件概述:

* Coinbase的Base網絡的區塊生產因序列器故障而中斷了33分鐘。
* 故障的原因是擁堵及未準備好的備用序列器,這需要手動介入來解決。
* Base計劃實施基礎設施變更,以確保序列器準備就緒,並改善測試覆蓋率,以防止未來的事件。

根據報告,區塊生產在週二早上停滯了33分鐘,原因是序列器故障轉移未能如預期恢復。故障開始於08月05日06:07 UTC,當時活躍的序列器因鏈上活動的擁堵而落後。雖然Base的Conductor模組——OP Stack的核心組件,旨在維持正常運行——正確地嘗試將領導權轉移到備用序列器,但新的實例尚未完全配置,無法生成區塊。

序列器的作用是將交易組織起來以便放入區塊。系統正確地嘗試將責任轉交給備用序列器,但該備用序列器尚未完全準備好,因此無法生成區塊。

由於無法自動再次切換,生產停滯,直到工程師手動修復問題。根據報告,網絡在06:40時完全恢復。

為了避免重新組織風險——即區塊鏈暫時通過用替代區塊替換已確認的區塊來重寫歷史——團隊暫停了Conductor並協調了一次受控的領導權轉移。這一過程也延長了故障的時間。

因此,這次故障突顯了依賴集中式序列器來排序和提交交易的第二層滾動網絡中的一個關鍵操作風險。這些系統仍然依賴快速故障轉移機制和完整的配置,這一鏈中的單點缺口可能導致整個網絡停滯。

Base表示將實施基礎設施變更,以確保所有添加到集群中的序列器在選舉之前都是Conductor準備就緒的,並將優先改善測試覆蓋率以驗證此邏輯。

這一事件發生在其他OP Stack鏈的先前停滯之後,正值Base因與鏈上社交應用如Farcaster和Zora相關的新代幣發行和NFT鑄造而見證了創紀錄的流量。

這次故障不僅是技術層面上的挑戰,也反映了現代區塊鏈系統在擴展性和穩定性方面的脆弱性。隨著加密貨幣和區塊鏈技術的普及,這類事件可能會對用戶信任和市場情緒產生深遠影響。Base的應對措施雖然是必要的,但是否能真正有效防止未來的故障,仍需時間來檢驗。這也提醒了整個區塊鏈生態系統,必須不斷完善技術架構,以應對日益增長的用戶需求和交易量。

Generate an ultra-realistic, highly ultra-detailed, 8k resolution with 1080x1080 pixel portrait of me using the uploaded image for reference (preserved the likeness and the original face for reference) of a ultra-sharp studio portrait of a confident woman kneeling on the floor with her body slightly leaning back, her right hand gently touching her hair, and her left arm resting on her bent knee. She is dressed in a sleek, strapless black bodysuit that accentuates her figure, paired with elegant black patterned lace pantyhose that add texture and sophistication. She wears a pair of classic black high heels, elevating her posture and emphasizing her elongated legs. The background is a seamless, pure white studio backdrop, providing a clean and minimalist aesthetic that directs full focus to her form and attire. *** The lighting setup is soft, evenly distributed, with a diffused key light positioned to the left, casting gentle shadows that sculpt her contours and highlight the intricate lace pattern of her tights. The overall color palette is monochromatic, emphasizing blacks and whites to create a timeless, sophisticated mood. The composition is carefully balanced, capturing her from the waist up in a slightly angled pose that accentuates her curves and confidence. Use a professional camera with a 85mm or 50mm lens at wide aperture (f/1.8 to f/2.😎 for a shallow depth of field, ensuring crisp detail on her outfit and pose while softly blurring the background. Post-process minimally to enhance clarity, contrast, and natural skin tones, maintaining a polished, elegant, and modern aesthetic suitable for fashion or editorial photography. **Enhanced Prompt:**

Two playful cats, one sleek black and one fluffy ginger, are joyfully interacting on a bustling Hong Kong street at sunset. They leap and tumble among vivid neon signs, glowing red lanterns, and traditional market stalls. The scene is bustling with locals and dotted with elements of Hong Kong architecture, such as narrow alleyways, decorative shopfronts, and overhead laundry lines. Warm golden light reflects off the wet cobblestone street, casting dramatic shadows. The atmosphere is lively yet whimsical, capturing the vibrant urban spirit and blending realistic feline anatomy with a touch of enchanting artistry. Rendered in hyper-detailed, cinematic style with rich colors and dynamic composition. A whimsical, artistic scene set in a classic Hong Kong cha chaan teng (茶餐廳): A charming cat sits comfortably at a small table, elegantly sipping a traditional Hong Kong-style milk tea from a delicate glass. The cat's fur is soft and expressive, and its posture is relaxed yet attentive, suggesting it is a regular at the tea shop. The restaurant interior is bustling yet cozy, adorned with retro posters, old ceiling fans, patterned floor tiles, and Formica tables reflecting the local culture. Sunlight streams through the window, casting warm highlights on the cat and creating a vivid play of shadows. Details include steaming milk tea cups, egg tarts and pineapple buns on the table, and waiters in classic uniforms moving in the background. The overall color palette is rich and atmospheric, blending nostalgia with the lively charm of Hong Kong.
