MEV影響DeFi發展,機構用戶受損




MEV驅使機構遠離DeFi,令用戶付出沉重代價:加密貨幣高管

在交易執行前廣播交易會對零售加密貨幣用戶施加「隱形稅」,同時使金融機構感到疏離。

根據DEX Labs的首席執行官Aditya Palepu的說法,最大可提取價值(MEV)——即礦工或驗證者在區塊中重新排序交易以提取利潤的過程——正在阻止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告訴Cointelegraph,所有電子交易市場都受到MEV或類似問題的影響,這是由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來防止訂單流數據在執行前可見,這些環境通過資金保管庫或其他機制私下處理交易。他補充道:

> “它們真正強大的地方在於可以私下處理訂單。因此,你的交易意圖在執行前不會被廣播到全世界。它們在客戶端加密,只有在安全區域內經過排序後才會解密。”

他表示,這使得前置交易變得「不可能」,保護用戶免受「三明治攻擊」等市場操縱行為的侵害,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放置交易,以操縱價格並提取利潤。

MEV作為加密和DeFi的核心基礎設施的存在,引發了行業高管和協議創始人之間的激烈辯論,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遊戲對零售用戶造成損害

Palepu告訴Cointelegraph,缺乏交易隱私使金融機構無法採用DeFi,因為這使它們面臨市場操縱和前置交易的風險,因為交易在執行前被廣播。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,機構創造了金融市場運行所需的「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,這些機會減少了價格波動,並保持資產價格在交易所之間的接近平衡。他指出:「交易所,像任何市場一樣,需要活力和多樣化的參與。」他表示,缺乏機構參與可能會導致流動性枯竭、波動性上升、市場操縱增加和交易成本飆升。

在當前的加密貨幣市場中,MEV的問題不僅影響了機構的參與意願,也對普通用戶造成了實質性的損失。這不僅是一個技術問題,更是對整個金融生態系統的挑戰。隨著DeFi的發展,如何平衡透明性與隱私,保障用戶的交易安全,將成為未來的關鍵議題。這也提醒我們,金融科技的進步必須伴隨相應的監管和保護措施,以確保所有參與者的利益。

A rugged post-apocalyptic survivor standing in a wasteland, hyper-realistic portrait. A young man with a shaved military-style haircut, dirt- and blood-stained face, visible scars, intense determined eyes. Wearing layered tactical clothing: torn and weathered jacket, patched sleeves, multiple scarves and cloth wraps in earthy tones, tactical pants with reinforced padding. Covered in survival gear: large worn backpack, utility pouches on chest and waist, rope, knives, handmade tools, makeshift firearm at the hip. Textures of dust, rust, scratches on all equipment. Cinematic dystopian lighting, muted earthy color palette, shallow depth of field, dramatic storytelling atmosphere, ultra-detailed, photorealistic, 50mm lens. The same person, the same face, unaltered features. An almost hyperrealistic image with sharp detail, a stylish photograph captures a model standing against a backdrop of pristine white volcanic rocks. The stones are expertly arranged, revealing natural cracks in the beige hue. In a medium-length shot, the balance of luxury and meticulous attention to detail is striking. She wears a carefully tailored white suit: a jacket with a structured fabric, high shoulders, and precise waist trim, a deep V-neck that elegantly reveals the neckline without being contrived, and matching skirts that maintain clean lines and lend the look a classic, understated elegance. The head is covered by a wide-brimmed white straw hat, its high angle pointing forward and adorned with a bouquet of red and white roses resting on the front brim, adding a touch of drama and romance. Green eyes, professional makeup, full lips, and long, sleek blonde hair cascading over her shoulders. Her right hand lifts the brim of the hat as if adjusting it, while her left hand crosses her chest in a confident pose that reflects a strong feminine presence. The fabric's lines and texture are carefully highlighted with a long, graceful touch of movement. The fabric details are delicate and soft, with subtle ripples and hidden seams that enhance the sense of high craftsmanship. Soft lighting from the left creates a long shadow on the wall, giving the image depth and body without compromising the purity of the white. Shades of white blend with a touch of warm gray, and the red roses stand out as a focal point, adding warmth and visual dimension. The stone background creates a calming effect, allowing the fine details of the hat, suit, and roses to stand out. White volcanic stones. Natural fissures.

Create a portrait of a  fair-skinned woman with long, curly dark hair styled in a high ponytail, her head turned to the side, her expression neutral and serene; her makeup features defined eyebrows, subtle eyeliner, light blush, and glossy lips; she wears dangling earrings with a floral design; she has a piercing in her ear; the image is in ultra-high 8K resolution, showcasing detailed skin textures, crisp edges, and sharp focus on her eyes; a medium shot, taken from the side to emphasize her profile, with a shallow depth of field that softly blurs the background; soft, diffused lighting illuminates her face evenly, creating subtle shadows and highlights, with a warm color palette of soft browns and creams; she is wearing a dark strapless top; the background is a soft, neutral tone, ensuring the focus remains on the subject; no additional props are present; photorealistic style, akin to a raw camera capture, is achieved using an 85mm lens, ISO 100, and an aperture of f/2.0 for a shallow depth of field and soft background blur.
