So to understand what a radical change this is going to bring, let's look at one industry, financial services.
所以為了理解即將到來的突破性的改變，讓我們看一個行業：金融服務業。
Recognize this? Rube Goldberg machine.
你們能否認出這是什么？小題大做的機器。
It's a ridiculously complicated machine that does something really simple, like crack an egg or shut a door.
這臺機器離奇地復雜，工作卻很簡單，像是敲碎雞蛋或是關上門等。
Well, it kind of reminds me of the financial services industry, honestly.
老實說，它使我想起了金融服務業。
I mean, you tap your card in the corner store,
我的意思是，你在街角的商店刷了卡，
and a bitstream goes through a dozen companies, each with their own computer system,
一股比特流便穿過了好幾家公司，每一家都有自己的計算機系統，
some of them being 1970s mainframes, older than many of the people in this room, and three days later, a settlement occurs.
其中還有一些20世紀70年代的主機，甚至比在座的各位還要老，然后三天過后，一份交易說明誕生了。
Well, with a blockchain financial industry, there would be no settlement,
好吧，金融業有了區塊鏈，將不再會有交易說明，
because the payment and the settlement is the same activity, it's just a change in the ledger.
因為交易和交易說明是同一種行為，它只是在賬本中有所不同。
So Wall Street and all around the world, the financial industry is in a big upheaval about this,
所以在華爾街或世界上所有地方，金融業正在巨變，
wondering, can we be replaced, or how do we embrace this technology for success?
思考著自己是否會被取代，或是如何正視技術迎接成功？
Now, why should you care? Well, let me describe some applications.
現在為什么要在意呢？讓我來講述幾個應用吧。
