MEV影響DeFi,機構投資者為何退縮?

MEV驅動機構遠離DeFi,讓用戶付出高昂代價:加密執行官

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損害。

Palepu在接受Cointelegraph訪問時表示,所有電子交易市場都受到最大可提取價值或類似問題的影響,這些問題源於交易數據排序中的信息不對稱。他指出,解決方案是通過在可信執行環境中處理交易,防止訂單流數據在執行前可見,這些環境可以通過資金保管庫或其他機制私下處理交易。他補充道:

> “使它們真正強大的原因在於它們可以私下處理訂單。因此,在執行之前,你的交易意圖不會被廣播到全世界。它們在客戶端加密,只有在安全區域內按順序解密。”

這樣一來,前置交易(front-running)就變得“不可行”,從而保護用戶免受“夾擊攻擊”(sandwich attacks)等市場操縱行為的影響,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放置交易,以操縱價格並提取利潤。

MEV作為加密和DeFi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,因為他們試圖解決MEV可能導致的集中化、成本上升以及抑制大規模採用的問題。

機構不參與DeFi遊戲傷害零售用戶

Palepu告訴Cointelegraph,交易隱私的缺乏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風險,因為交易在執行前被廣播。“當機構無法有效參與時,所有人都會受害,包括零售用戶,”Palepu說,並補充道,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。

他還補充道,這些基礎設施包括非提取性的套利交易機會,這些機會可以減少價格波動,並使資產價格在不同交易所之間保持大致一致。

“交易所,像任何市場一樣,需要活力和多樣化的參與,”Palepu說,並指出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飆升。

在這篇報導中,我們可以看到MEV對於加密貨幣生態系統的深遠影響。這不僅僅是技術上的挑戰,更是對整個市場結構的考驗。隨著DeFi的興起,如何平衡透明性和隱私、效率與公平性將成為未來的關鍵議題。機構參與的缺乏不僅影響了市場的流動性,更可能阻礙新技術的採用和創新。因此,解決MEV問題的同時,還需考慮如何吸引機構回歸DeFi,這將是推動整個行業向前發展的關鍵。

A captivating portrait of a young Asian woman, inspired by Imada Mio and embodying an exquisitely delicate, doll-like (精緻洋娃娃臉) aesthetic. She has large, round, expressive eyes that radiate innocence and curiosity, subtly accented with a moist shimmer. Her petite V-line face is framed by soft, rosy cheeks, and her lips are naturally pink and slightly parted, exuding an energetic, slightly flirty, yet pure aura. Her expression is a candid blend of sweetness and playful allure.

Her long, dark brown hair is artfully tousled with a messy morning (剛睡醒的凌亂感) effect—loose strands fall gently around her face, conveying natural volume and effortless beauty. The hair has a silky texture, catching the light in places, suggesting a recent awakening.

She is dressed in an oversized, translucent white button-down shirt (男友風白襯衫) with the top buttons casually undone, delicately revealing her collarbones and a slender neckline. The shirt drapes loosely, giving a tasteful "bottomless" look (下衣失蹤風格), her bare legs just barely visible beneath the shirt's hem, enhancing the innocent-meets-sensual ambiance.

The composition is styled in the manner of a Japanese Gravure Photobook (寫真集風格), exuding a pure & sexy vibe with an airy, dreamy atmosphere. Employ bright, high-key lighting for a clean, luminous effect that highlights her velvety soft skin texture. Use Fujifilm PRO 400H film tones for subtle pastel hues, gentle contrast, and a seamless blend of natural colors, further enriching the soft, ethereal, and intimate photographic quality.

The background is minimalist and softly blurred, ensuring complete focus on the subject, and enhancing the overall sense of warmth, comfort, and inviting allure typical of high-end Japanese photobooks.
