代幣化銀行存款能否取代穩定幣?




哥倫比亞商學院教授質疑代幣化銀行存款的可行性

根據哥倫比亞商學院的兼任教授奧米德·馬雷坎(Omid Malekan)的說法,代幣化銀行存款缺乏穩定幣的靈活性和技術特性,因此是一種劣質產品。

銀行和金融機構已經開始實驗代幣化銀行存款,即在區塊鏈上記錄的銀行餘額,但馬雷坎認為,這項技術注定會輸給穩定幣。

他指出,過度擔保的穩定幣發行者必須保持1:1的現金或短期現金等價物儲備來支持其代幣,從責任的角度來看,比發行代幣化銀行存款的部分準備金銀行更安全。

穩定幣還具有可組合性,這意味著它們可以在加密生態系統中轉移並用於各種應用,與此不同的是,代幣化存款是受限的,具有「了解你的客戶」(KYC)控制,並且功能受到限制。

馬雷坎進一步表示,代幣化銀行存款就像是一個「只能向同一家銀行的其他客戶開支票的支票帳戶」。他補充道:

> 「這樣的代幣有什麼意義?這種代幣無法用於大多數活動。它對跨境支付毫無用處,無法服務於無銀行賬戶的人,沒有可組合性,也無法與其他資產進行原子交換,並且無法用於去中心化金融(DeFi)。」

根據標準銀行的預測,代幣化現實世界資產(RWA)部門,包括法定貨幣、房地產、股票、債券、商品、藝術品和收藏品,預計到2028年將膨脹至2萬億美元。

代幣化銀行存款必須與收益型穩定幣競爭

馬雷坎還指出,代幣化銀行存款必須與收益型穩定幣競爭,或者與那些找到方法繞過GENIUS穩定幣法案中收益禁止的穩定幣發行者競爭,後者以各種客戶獎勵的形式傳遞收益。

銀行遊說團體對收益型穩定幣表示反對,擔心穩定幣發行者與客戶分享利息會侵蝕銀行業的市場份額。

目前,美國或英國零售銀行的儲蓄賬戶平均利率低於1%,使得任何高於這一水平的收益對客戶來說都具有吸引力。

紐約大學教授奧斯丁·坎貝爾(Austin Campbell)批評銀行遊說團體對收益型穩定幣的抵制,指責銀行業利用政治壓力來保護其金融利益,卻犧牲了零售客戶的利益。

這一討論不僅揭示了代幣化銀行存款的局限性,還反映了傳統金融與加密貨幣生態系統之間的緊張關係。隨著加密技術的發展,銀行業必須重新思考其商業模式,以適應這一不斷變化的市場環境。這也意味著,未來的金融服務可能會更加多元化,消費者將能夠享受到更具競爭力的產品與服務。

Create a photorealistic and highly detailed image featuring the attached image walking confidently down a modern city street, accompanied by Jason Statham, Dwayne “The Rock” Johnson, and Jason Momoa acting as bodyguards.
John Wick (Keanu Reeves) is walking just beside or slightly behind the subject, holding an umbrella over him to shield from light rain.
The subject should be the central figure, wearing stylish casual clothing — like a fitted jacket, dark jeans, and sunglasses — exuding calm authority and cool charisma.
Statham, The Rock, and Momoa are dressed in black tactical-style suits, maintaining alert, protective stances, scanning the surroundings like professional bodyguards. John Wick wears his signature black suit and tie, looking composed as he holds the umbrella.
The setting is a downtown urban street with wet pavement reflecting city lights, parked luxury cars, and paparazzi in the background snapping photos.
The photo should look like a real paparazzi shot — slightly off-angle, mid-step motion blur, with realistic lighting and reflections.
Lighting: natural daylight with overcast skies, reflections from wet concrete, realistic shadows, subtle raindrops on the umbrella and clothing.
Camera realism: crisp detail on facial features and clothing textures, shallow depth of field emphasizing the group, with lens flare or light bloom for authenticity.
Mood & tone: grounded, cinematic, and stylish — feels like a moment from a celebrity entourage photo or action-movie press capture, taken with an iPhone by paparazzi.
Style: ultra-realistic, documentary-style street photography with modern cinematic sharpness. Create a hyper-realistic promo image using my uploaded photo.  
Keep my real face exactly as it is (no changes to eyes, mouth, jawline, or skin).  
Place my portrait seamlessly inside the design of the US 100-dollar bill, maintaining the texture and engraving lines.  
Add two more versions:  
- One on the Euro (€100) banknote  
- One on the British Pound (£50) banknote  
Ensure the portrait blends naturally with the currency engraving style, with deep shadows, embossed effect, and authentic banknote detailing.
