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:加密執行官

在交易執行之前廣播交易會對零售加密用戶施加一種「隱性稅」,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)是指礦工或驗證者重新排列區塊中的交易以獲取利潤的過程,這一現象正阻礙金融機構採用去中心化金融(DeFi),而這對零售用戶造成了傷害。

Palepu 在接受 Cointelegraph 採訪時表示,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中的信息不對稱。

他指出,解決方案是防止訂單流數據在執行之前可見,這可以通過在受信執行環境中處理交易來實現,這些環境通過資金保管庫或其他機制私下處理交易。他補充說:

> 「它們真正強大的地方在於可以私下處理訂單。這樣,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,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」,從而保護用戶免受「三明治攻擊」等市場操縱行為的影響,這是一種操縱價格和提取利潤的市場操控方式,驗證者或礦工在用戶訂單之前和之後進行交易。

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 可能增加集中化、推高成本和抑制大規模採用的問題。

機構不參與 DeFi 對零售用戶造成傷害

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風險,因為交易在執行之前會被廣播。

他表示:「當機構無法有效參與時,所有人都會受害,包括零售用戶。」他補充說,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,這些機會可以減少價格波動,並使資產價格在不同交易所之間保持接近一致。

Palepu 說:「交易所就像任何市場一樣,需要參與的活力和多樣性。」他指出,缺乏機構參與可能導致流動性枯竭、波動性激增、市場操縱增加和交易成本上升。

在這個背景下,如何平衡去中心化和機構參與的需求,將成為未來 DeFi 發展的關鍵挑戰。隨著市場的不斷演變,解決 MEV 問題的方案將不僅影響零售用戶的交易體驗,也可能決定整個行業的未來走向。
