中性技術vs.人為錯誤
在加入幣安美國站擔任首席執(zhí)行官以前,我曾領導過美國貨幣監(jiān)理署,該署是美國聯(lián)邦銀行體系的主要監(jiān)管機構。因此,我知道金融監(jiān)管的主要關注點是那些由于人為疏忽或瀆職而產(chǎn)生的錯誤(例如,欺詐、自我交易、歧視、內(nèi)幕交易、建模出錯等)。
所有錯誤都是由決策過程中的某些人犯下的。例如,當某人違反信托義務,“提示”了他人,或自己根據(jù)內(nèi)幕信息進行非法證券交易時,就會發(fā)生內(nèi)幕交易。一個適當去中心化的技術體系則無心自行非法斂財或犯下其他罪行。絕大多數(shù)時候,尤其是與容易犯錯的人類同行相比,它的行為是中立的。以此類推,由人類的貪婪、無能或疏忽導致的其他違規(guī)行為也是如此。
設身處地為銀行審查員想想。你認為是檢查一個公開的開源軟件簡單,還是質詢一個可能會撒謊的人簡單?現(xiàn)在想象一下,如果導致我上文列出的所有失誤或不法行為出現(xiàn)的人為因素能夠大幅減少甚至消除,現(xiàn)在我們面臨的很多風險難道不會就此消失嗎?
我要強調(diào)一下,去中心化金融并非毫無風險。在去中心化金融體系中,洗錢現(xiàn)象仍然會出現(xiàn)(但可以說不會那么頻繁或相當容易)。編程不當?shù)乃惴ㄈ匀粫π抛u良好的少數(shù)族裔貸款申請人造成輕重不一的影響(但想必待遇上不會出現(xiàn)歧視問題)。而且,許多去中心化金融協(xié)議都與其原生代幣關系密切,這些代幣的波動性可能比投資者慣于處理的其他資產(chǎn)更大,這意味著風險披露尤為重要。但它仍不能改變這一事實,即如果這些技術得到了謹慎和恰當?shù)氖褂茫淇梢越栌梢淮渭夹g飛躍幫助解決許多金融體系風險,而不僅僅是逐步解決它們。
這一點很重要,也讓人很安心,因為去中心化金融的崛起好像幾乎是不可避免的,就像在美國人的生活中圖書館和郵局必然會被新穎的互聯(lián)網(wǎng)所取代一樣。顯然,銀行借以立足數(shù)百年的信息和信任不對稱已被技術,尤其是區(qū)塊鏈和人工智能所取代。人們對信息、商業(yè)和金融領域的大型中央存儲庫的需求已被技術所削弱,這些技術不僅可以借由去中心化和對等網(wǎng)絡等手段執(zhí)行同樣的職能,而且其速度更快價格又更低。
希望我們能夠意識到,我們的行為心理學模式使得一些人由于恐懼于早期的技術發(fā)展從而幾乎錯失了它們帶來的好處。是的,馬車鞭制造業(yè)被汽車業(yè)永久取代了,但我們大多數(shù)人的境況因此變得更好了。是的,許多備受推崇的實體零售店被網(wǎng)上購物永久取代了,但網(wǎng)購的速度和價格優(yōu)勢讓我們大多數(shù)人都過得更好了。然而再一次地,我們又在為一場新的技術革命的出現(xiàn)而擔心,而且這并不是因為目前的金融體系備受歡迎。這只是因為這個魔鬼已為我們所知。(財富中文網(wǎng))

At its core, innovation is exciting. It involves a new way of operating that can bring the promise of greater efficiency and access for consumers and businesses—beyond what we know in the moment. Think of the automobile, the transistor, or the smartphone. However, when innovation comes to finance, it is often met with skepticism over safety and suitability—an issue faced by fintech over the past decade. The good news is that we can all generally agree that fintech has made life easier for most people. Think of PayPal and Rocket Mortgage.
Today we hear about skepticism and worry over decentralized finance, or “DeFi.” Regulators have seen the rise of DeFi as increasing the risk in the traditional financial system. Given how skeptical we all were about past innovations that turned out to deliver major benefits, this isn’t terribly surprising. The question is, why does it need to be this way? Can we instead overcome our brains’ status quo bias and recognize that DeFi might reduce risks that exist in the traditional financial system?
First, some context. In the roughly 18 months since the emergence of DeFi at scale, approximately $80 billion of capital has been contributed to DeFi protocols—something big.
DeFi has grown this fast and become so significant for a reason. Every dollar contributed to a DeFi platform is a dollar someone decided not to deposit at a bank or invest with a traditional asset manager. Why? Because large numbers of people decided that the risk-adjusted benefits of DeFi participation were more favorable than traditional banking or investment services.
Let’s consider some of the shortcomings of consumer finance today. For as long as any of us can remember, the rates that savers can earn at banks have been depressed due to monetary policies such as post-financial-crisis quantitative easing and COVID-era stimulus programs. This problem is exacerbated by rampant hidden fees that may reduce customer return even when explicit trading fees go to zero (the “Robinhood effect”). And customers of one institution can’t trade with those of other institutions as a result of the inefficient “walled gardens” created by centralized structures (for example, Venmo users cannot pay Zelle users).
And then there’s the risk of human error—the possibility that, for example, a bank’s credit committee approves a risky loan that should not have been made or denies credit to a creditworthy borrower. Or, of even greater concern, that human discrimination will enter the equation, further disadvantaging certain groups or individuals.
It’s frustrating, for sure, so I come back to the question of why it needs to be this way. Why does our bias in favor of the risks we’re familiar with prevent us from seeing that DeFi, a new idea, might actually reduce or eliminate some of those risks?
Neutral technology vs. human fallibility
Before joining Binance.US as its CEO, I headed the Office of the Comptroller of the Currency (OCC), which is the primary overseer of the nation’s federal banking system. So I know that most of the focus of financial regulation is on mistakes that are made through human negligence or malfeasance (for example, fraud, self-dealing, discrimination, insider trading, modeling errors, and the like).
Each of these mistakes depends on there being a human being in the decision-making process. For example, insider trading happens when a person violates fiduciary duty and “tips” others, or acts on insider knowledge themselves, to illegally trade securities. A properly decentralized technology system has no desire to illegally enrich itself or perform other misdeeds. The vast majority of the time—particularly in comparison to its fallible human counterparts—it acts neutrally. So too with other violations caused by human greed, incompetence, or negligence.
Put yourself in the shoes of a bank examiner. Do you think it would be easier to examine a piece of open-source software that is transparent for all to see, or to question a human being who might be motivated to lie? Now imagine if the human factor that can lead to each of the mistakes or malfeasance I listed above could be substantially reduced or even eliminated. Wouldn’t that address a vast number of today’s risks?
Let me note that DeFi is not without risks. Money laundering can still happen (though, arguably, less frequently or easily) under decentralized financial systems. An improperly programmed algorithm can still result in disparate impact against creditworthy minority loan applicants (though it presumably can’t engage in disparate treatment discrimination). And many DeFi protocols are tightly integrated with their native token, whose value may be more volatile than other assets investors are accustomed to dealing with—meaning that risk disclosures are especially important. But the fact remains that these technologies, when carefully and properly used, can help to solve many financial-system risks in one leap of technology, not just address them incrementally.
This is important and reassuring, because the growth of DeFi seems almost inevitable, for the same reason that the displacement of libraries or post offices in American life was the inevitable result of the original Internet. The information and trust asymmetries that banks existed to intermediate centuries ago have been significantly displaced by technology, particularly blockchain and artificial intelligence. The need for great central repositories of information, commerce, and now finance is being reduced by technologies that allow decentralized peer-to-peer networks to perform the same functions more quickly and cheaply.
Hopefully we can recognize the behavioral psychology patterns that led some of us to fear earlier technology developments and almost led us to miss their benefits. Yes, buggy-whip manufacturers were permanently displaced by the auto industry, but most of us are far better off as a result. Yes, many venerated brick-and-mortar retailers were permanently displaced by the commercialization of the Internet, but the speed and price advantages of Internet shopping made most of us better off. Yet once again we fear a new technology revolution—and not because the status quo financial system is particularly loved. It is merely the devil we know.
