Make this photo use ultra realistis  A man sitting at a futuristic desk, interacting with a large, modern holographic touchscreen display similar to the technology in the Iron Man movies. On the desk, there is an Iron Man gauntlet (Infinity Gauntlet) with all the Infinity Stones glowing on it. Next to the gauntlet, there is a plate of grilled corn on the cob (jagung bakar) and a coffee cup beside the plate. The desk area is clean and free of any cables. The overall setting should be a realistic and modern high-tech lab/room with Iron Man, Captain America, and Black Panther suits displayed in pods behind him. Cinematic lighting, hyper-realistic, high detail.
Use the original face exactly as it is, without changing a details. A full-body photograph of a glamorous female model in a vibrant, retro 1950s pin-up style bikini. The lighting should be bright, sunny, and highly saturated, evocative of a vintage summer advertisement or a pop art aesthetic.
Model & Outfit:
• Model: A slender woman with a confident, slightly posed expression.
• Hair & Accessories: A white and blue patterned headband tied in a bow. Bold, dark cat-eye sunglasses. Large gold hoop earrings and thick, stacked gold bangle bracelets on both wrists. Bright red lipstick.
• Swimwear: A two-piece retro bikini with a high-waisted bottom and a halter-neck top. The top is turquoise/teal with white polka dots, featuring a large bow detail at the bust. The bottom is a contrasting, high-rise, ruched style in pale peach or coral with small dark polka dots.
Setting & Composition:
• Location: A mid-century modern-style poolside scene on a bright sunny day.
• Background Details: A sparkling blue swimming pool, several brightly colored lounge chairs (yellow, teal, pink), and large beach umbrellas (striped orange and white). There are large, bright flotation devices (yellow, teal, orange inner tube) scattered around the edge of the pool.
• Composition: Vertical, full-body shot. The model is centered, and the background is slightly blurred (shallow depth of field) to keep the focus on the model.
Aesthetic Keywords:
• Vibrant, High Saturation, Retro Summer, 1950s Pin-up, Mid-Century Modern, Pop Art, Poolside Glamour, Commercial Photography, Magazine Ad, Halter Bikini, High-Waisted, Sunny Day.
Base Setup

keep 100 percent facial information adherence of the attached image and turn her into a fashion model walking through a dim stone tunnel toward a bright exit, captured as a live action photograph or movie still, not an illustration or CGI render. Her styling leans seductive and attractive through fashion, attitude, and mood rather than explicit content.

Shot and Camera

Full body silhouette shot from behind at slightly low camera height, matching the original perspective and narrow tunnel framing. Keep her stride, tunnel curvature, and vanishing light exactly as seen.

Identity and Pose

Preserve her height impression, slim silhouette, hair length, and body proportions. She walks forward with one hip subtly angled, natural arm swing, confident stride, and a slow, sensual rhythm. Her head tilts slightly as if aware of being watched. Include 8k Photorealistic and hyper realistic.

Lighting and Environment

Strong backlight from the tunnel exit creates a glowing rim around her body, with soft, scattered reflections on the wet stone floor. The tunnel remains dark with textured stone irregularities and real moisture streaks. Add subtle haze for realism and keep the environment grounded with accurate shadows and surface wear.

Masking and Constraints

Change only the outfit and styling, keep lighting, perspective, white balance, pose, face geometry, body proportions, and silhouette the same. Absolutely no added text, no cartoon look, no CGI sheen, no plastic skin, no floating feet, and no overly clean backgrounds. Maintain consistent perspective, grounded contact shadows, film like grain, and full live action realism.

未知攻擊者在Sepolia的Pectra升級中造成困擾

以太坊最近在Sepolia測試網進行的Pectra升級遇到了問題,這一問題因為一名未知用戶發送零代幣轉賬而變得更加嚴重。

以太坊開發者Marius van der Wijden表示,Pectra在3月5日早上7:29於其最後的測試網Sepolia推出,但在3月8日的帖子中,他提到團隊立即開始在其geth節點上看到錯誤信息,並且出現了空區塊的情況。

根據Van der Wijden的說法,錯誤是因為存款合約觸發了錯誤類型的事件——一個轉賬事件而不是存款事件。

雖然已經推出了修復,但Van der Wijden表示他們錯過了一個邊緣案例,而一名未知用戶利用這一點,向存款地址發送了0代幣的轉賬,這再次觸發了錯誤。

“幾分鐘後,我們又看到很多空區塊,所以我們再次查看交易池,發現另一個觸發相同邊緣案例的有問題交易,”他說。

“起初我們以為是某個受信任的驗證者犯了錯,但我們很快意識到這筆交易來自一個最近由水龍頭資助的新賬戶。”

根據Van der Wijden的說法,ERC-20標準並不禁止零代幣轉賬;這使得任何人,即使他們沒有任何代幣,也能向另一個地址進行轉賬,而這正是未知用戶所意識到的。

“阻止這次攻擊的唯一方法就是過濾掉所有與存款合約互動的交易。因此,我們進行了以下私密修復,並將其部署到幾個DevOps節點。”

“我們懷疑攻擊者在閱讀我們的一些聊天記錄,所以我們決定不公開這個修復,而只是更新我們控制的幾個節點,以便在網絡上獲得更多完整的區塊,”他補充道。

到下午2點,所有節點都已更新了修復,並且未知用戶的交易成功被挖掘。

Van der Wijden表示,在事件期間他們從未失去最終確認,問題僅限於Sepolia,因為他們使用的是一個代幣限制的存款合約,而非正常的主網存款合約。

此前,開發者在2月26日的Holesky測試網上測試了Pectra升級,當時也遇到了問題。

因此,開發者決定推遲Pectra升級,直到可以進行更多測試。

評論

這次事件突顯了區塊鏈技術在安全性和穩定性方面的脆弱性,尤其是在進行重大升級時。雖然開發者迅速反應並修復了問題,但這也反映出在開發過程中對潛在邊緣案例的忽視。隨著區塊鏈技術的普及,未來可能會有更多類似的攻擊出現,這要求開發者在設計合約時必須更加謹慎,並進行更全面的測試。

此外,這次事件也提醒我們,社群的透明度和信息共享的重要性。在面對攻擊時,開發者選擇不公開修復方案,雖然短期內有效,但長期來看可能會影響社群對項目的信任。未來,如何在安全性和透明度之間取得平衡,將是區塊鏈項目面臨的一大挑戰。
