MEV影響DeFi發展,零售用戶受損




MEV 驅使機構遠離 DeFi,讓用戶付出高昂代價:加密執行長

根據 DEX Labs 的首席執行官 Aditya Palepu 的說法,最大可提取價值(MEV)這一過程,即礦工或驗證者重新排序區塊中的交易以提取利潤,正在阻礙金融機構採用去中心化金融(DeFi),這對零售用戶造成了傷害。

Palepu 在接受 Cointelegraph 訪問時指出,所有電子交易市場都受到 MEV 或類似問題的影響,這主要源於交易數據排序中的信息不對稱。他表示,解決方案是通過在可信執行環境中處理交易,防止訂單流數據在執行前被公開,這樣可以通過資金保管庫或其他機制私密地處理交易。

他補充道:“它們真正強大的地方在於可以私密地處理訂單。因此,在執行之前,你的交易意圖不會被全世界廣播。它們在客戶端進行加密,只有在安全區域內經過排序後才會解密。”

這樣一來,前置交易就變得“不可能”,保護用戶免受“夾擊攻擊”的影響,這是一種市場操縱形式,驗證者或礦工在用戶訂單之前和之後下單以操縱價格並提取利潤。

MEV 作為加密和 DeFi 的核心基礎設施,已引發行業高管和協議創始人之間的激烈討論,因為他們試圖解決 MEV 可能導致的中心化增加、成本上升和大眾採用受阻的問題。

機構不參與 DeFi 影響零售用戶

Palepu 指出,缺乏交易隱私使金融機構無法有效參與 DeFi,因為這會使它們面臨市場操縱和前置交易的風險。他表示:“當機構無法有效參與時,所有人都會受到影響,包括零售用戶。”他補充道,機構為金融市場的順利運行創造了“高速公路和道路”或必要的交易基礎設施。

這些基礎設施包括非提取性的套利交易機會,這些機會能減少價格波動,並保持資產價格在各交易所之間的接近平衡。他強調:“交易所就像任何市場一樣,需要活力和多樣的參與。”缺乏機構參與可能導致流動性枯竭、波動性上升、市場操縱增加以及交易成本上升。

在當前的加密市場中,MEV 的問題不僅影響了機構的參與意願,也直接影響到普通投資者的利益。隨著 DeFi 的發展,如何平衡透明度與隱私保護,將成為未來金融科技的重要課題。這不僅是技術上的挑戰,更是對市場規範和用戶信任的考驗。

A full-body studio portrait of an elderly man with a bald head and a long, thick white beard, standing confidently beside a muscular grey pit bull dog. The man wears layered monochromatic olive-green tactical fashion: a quilted asymmetric jacket with mixed textures, loose padded cargo pants, and rugged military-style sneakers. His hands rest casually in his pockets as he gazes thoughtfully to the side, calm and powerful. The dog sits alert at his side, wearing a black studded collar, matching the strong, loyal aesthetic. Minimalist studio background in soft matte olive green, seamless floor and wall. Soft cinematic lighting with subtle shadows, high fashion editorial style, ultra-detailed fabric textures, muted earthy color palette, sharp focus, realistic skin tones, dramatic yet elegant mood, 8K resolution, professional fashion photography, Vogue editorial, modern urban warrior aesthetic. Photorealistic recreation of the iconic grocery shopping scene from Home Alone, set on a snowy winter street in New York City with yellow taxis, steam rising from manholes, holiday lights on buildings, and pedestrians in the background. In the foreground, a man (his face is 100% same as the uploaded photo), smile gently, wearing a white sweater and a light beige scarf around his neck, is taking a selfie-style close-up photo. Behind him and slightly to the right, a young boy (recreated exactly like Kevin McCallister from Home Alone) with short blonde hair, wide-eyed surprised expression, wearing a red knit hat, red scarf, beige coat, gray gloves, holding two full plastic grocery bags (one with oranges visible, the other with a carton of milk and cereal boxes). The boy is standing on the snowy sidewalk looking shocked. Cinematic lighting, cold winter atmosphere, high detail, sharp focus, realistic textures on clothing and snow, film still style from 1990s holiday movie. Certainly! Here’s an enhanced, detailed, and artistic version of your prompt:

A charming and elegant cat sitting gracefully on a Parisian balcony, overlooking the romantic cityscape of Paris at sunset. The cat’s fur is soft and glossy, perhaps a classic tabby or a sleek black cat, with expressive, intelligent eyes. Delicate wrought-iron railings surround the balcony, adorned with blooming flower boxes of vibrant geraniums and lavender. In the distance, the Eiffel Tower rises majestically above the rooftops, bathed in warm golden and pink light. The artist’s style is a blend of impressionism and realism, capturing intricate city details—cobblestone streets, classic Parisian architecture, and atmospheric lighting. The mood is dreamy, whimsical, and full of European charm, evoking a sense of wonder and adventure.
