An intense, close-up portrait set in a smoky, underground jazz club or speakeasy. The subject is the 'Boss' of an information network, hiding in plain sight. The scene is dark, defined by heavy shadows and cigarette smoke swirling in the air. A single spotlight hits the subject from the side, creating a classic 'Rembrandt triangle' on the cheek of [exactly face uploaded image 100%]. He wears a sharp, pinstripe suit with a silk tie, loosened at the collar. He holds a glass of amber whiskey, the condensation rendered in 8K detail. The camera uses a macro 100mm lens, focusing entirely on the eyes and the texture of the skin, blurring out the background patrons into abstract shapes. The mood is conspiratorial, sophisticated, and deeply atmospheric.
Create an image that captures a person working on a laptop while sitting on a wooden beach chair on a sandy beach.
Here are some key details:
Subject: A man uploaded photo wearing a light-colored, long-sleeved shirt open botten (possibly linen or a light denim), dark shorts. He is focused intently on the screen and keyboard of his silver laptop.
Setting: The scene is set on a beach during sunset or sunrise, indicated by the warm, golden light and the long shadows. There is a palm tree towering over the person, and its fronds are visible against the bright sky. The ocean is in the background.
Atmosphere: The overall mood is one of a "digital nomad" or someone enjoying the flexibility of working remotely in a beautiful, relaxed, and warm location. The lighting creates a very aesthetic and aspirational feel.
Foreground Detail: To the left of the chair, there's a wooden crate or small table where a portion of a coconut appears to be resting.
The photo effectively contrasts the intensity of work with the serene,
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.

MEV 驅使機構遠離 DeFi,令用戶付出高昂代價:加密高管

在交易執行前廣播交易會對零售加密用戶施加「隱性稅」,同時使金融機構感到疏離。

根據去中心化加密衍生品交易所 DerivaDEX 的首席貢獻者、DEX Labs 的 CEO Aditya Palepu,最大可提取價值(MEV)是指礦工或驗證者在一個區塊中重新排序交易以提取利潤的過程,這使得金融機構無法採用去中心化金融(DeFi),從而損害了零售用戶的利益。

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,防止訂單流數據在執行前被公開,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:

> 「它們的強大之處在於能夠私下處理訂單。這樣你的交易意圖在執行前不會被廣播到全世界。它們在客戶端進行加密,並且只有在安全區域內在排序後才會解密。」

這使得前置交易變得「不可能」,保護用戶免受「三明治攻擊」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,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、推高成本和阻礙大規模採用的問題。

機構不參與 DeFi 影響零售用戶

Palepu 表示,缺乏交易隱私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,因為交易在執行前被廣播。

他告訴 Cointelegraph:「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。

這些包括非提取的套利交易機會,這些機會減少價格波動,並保持資產價格在各交易所之間接近平價。

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

這篇文章引發了對加密市場中 MEV 的深入思考。MEV 的存在不僅影響了零售用戶的交易成本,還可能妨礙整個 DeFi 生態系統的健康發展。隨著機構投資者的缺席,市場的流動性和穩定性受到威脅,這使得 DeFi 的潛力無法完全釋放。未來,如何平衡透明度與隱私、競爭與公平,將是業界需要共同面對的挑戰。
