MEV影響DeFi發展,零售用戶受損




MEV 驅使機構遠離 DeFi,令用戶付出高昂代價:加密貨幣高管

在交易執行之前廣播交易,對零售加密貨幣用戶施加了一種「隱性稅收」,同時也使金融機構感到疏遠。

根據 DEX Labs 的首席執行官 Aditya Palepu 的說法,最大可提取價值(MEV)——即礦工或驗證者重新排序區塊中的交易以提取利潤的過程——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 訪問時表示,所有電子交易市場都受到 MEV 或類似問題的影響,這些問題源於交易數據排序的資訊不對稱。

他指出,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之前可見,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之前不會被廣播到全世界。它們在客戶端加密,並且只有在安全區域內按順序解密。”

他表示,這樣可以使前置交易變得「不可能」,保護用戶免受「三明治攻擊」等市場操縱行為的影響,這是一種市場操縱手法,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 可能導致的集中化、成本上升和阻礙大規模採用的問題。

機構不參與 DeFi 影響零售用戶

Palepu 指出,交易隱私的缺乏使金融機構無法採用 DeFi,因為這使他們面臨市場操縱和前置交易的風險,因為交易在執行之前就已經被廣播。他表示:

「當機構無法有效參與時,每個人都會受到影響,包括零售用戶。」他補充說,機構為金融市場的順利運作創造了「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,這些機會能夠減少價格波動,並保持資產價格在各交易所之間的接近平衡。他表示:

「交易所就像任何市場一樣,需要活力和多樣化的參與。」他補充說,缺乏機構參與可能導致流動性枯竭、波動性上升、市場操縱增加和交易成本上升。

在這個背景下,MEV 的問題不僅是技術上的挑戰,更是對整個加密貨幣生態系統的考驗。隨著越來越多的機構對 DeFi 表現出興趣,如何解決 MEV 帶來的隱私和安全問題,將成為未來發展的關鍵。這不僅影響到機構的參與意願,也直接關係到零售用戶的利益和整個市場的健康發展。

Create a portrait of a man (from attached photo) made of tiny ceramic mosaic tiles. Man is dressed in black oversized shirt and cargo pants. The image should look like a wall mural in a graffiti alley. People walking by and looking at the portrait. 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.
